Description

Storage medium, electronic device, game screen display method and device

Technical Field

The invention relates to the field of internet, in particular to a storage medium, an electronic device, a game picture display method and a game picture display device.

Background

In a game, the starry sky belongs to a very typical and classical scene, and the main implementation mode of the starry sky is realized by a sky box, a fixed model of human art or frame animation.

(1) The sky box implementation is shown in fig. 1, in which a game scene is enclosed by 6 boxes of maps (corresponding to the positive and negative poles of the X, Y, and Z axes in a three-dimensional coordinate system).

(2) The manner of implementation with fixed models of art is shown in fig. 2 and 3. The stars in fig. 2 and 3 may be of various shapes.

(3) The frame animation is implemented as shown in fig. 4, and the change of the stars, such as the size of the stars, the positions of the stars, etc., is implemented by the difference between the frames.

In the technical scheme of the 'implementation by using a sky box', the camera cannot rotate under perspective projection, so that the camera adopts orthogonal projection and can only move in parallel, and cannot express the sense of depth. As shown in fig. 5, the effect is obtained after the projection of the camera is changed to the orthogonal projection, and the cloud layer is significantly deformed, and the depth feeling cannot be displayed.

In the technical scheme of "realizing by using the fixed model of art", art needs to manufacture a lot of resources (how many stars need to be manufactured according to how many stars need to be manufactured), and has certain fixity, and the fixed model is monotonous or wastes art resources.

For the flickering stars, the game generally uses the frame animation to simulate the shining of the stars, the resource waste is large (including art resources and game resources), and the picture is single.

In addition, objects such as stars and the like are often projected into the animation in an orthogonal projection mode in the game, and due to the fact that the number of stars is large, the babysbreath occupies most of the area of a picture when being projected into the animation, and is not layered and poor in sense of reality, and game experience is affected.

Aiming at the technical problem that the area of a game animation picture occupied by stars in a starry sky scene in the related art is too large, an effective solution is not provided at present.

Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

First, partial terms or terms appearing in the description of the embodiments of the present invention are applied to the following explanations:

orthogonal projection: the projection of the projection line perpendicular to the projection plane belongs to orthogonal projection and belongs to one of parallel projection.

Alpha channel: is an 8-bit gray channel that records transparency information in an image with 256 levels of gray, defining transparent, opaque and translucent areas, where white indicates opaque, black indicates transparent and gray indicates translucent.

A sky box: the PANORAMIC image can be mapped by a PANORAMIC picture or PANORAMIC photograph, which is also called PANORAMA, and the English is PANORAMIC PHOTO, or PANORAMA, and generally refers to a photograph which is shot according to the normal effective visual angle of two eyes of a human (about horizontal 90 degrees and vertical 70 degrees) or comprises the visual angle of the residual light of two eyes (about horizontal 180 degrees and vertical 90 degrees) or even a complete scene range of 360 degrees.

View cone body: is a three-dimensional volume whose position is relative to the camera, and the shape of the view frustum determines how the model is projected from the camera space onto the screen. The most common type of projection, perspective projection, is such that objects near the camera are projected larger, while objects further from the camera are projected smaller. Perspective projection uses a pyramid as the view frustum, with the camera located at the vertex of the pyramid. The pyramid is truncated by two planes, one in front of the other, forming a Frustum called the viewing pyramid ViewFrustum, only the model inside the Frustum being visible.

Unity 3D: is a comprehensive game development tool developed by Unity Technologies to create multiple platforms of types of interactive content, such as three-dimensional video games, building visualizations, real-time three-dimensional animations, etc., is a fully integrated professional game engine.

NPC: the concept of Non-Player Character, which is an abbreviation of English Non Player Character, is also called Non-person Character or Non-Player Character, and the concept originally originated from a single-Player game and gradually extended to the whole game field, which generally refers to all characters in games that are not controlled by players.

According to an embodiment of the present invention, there is provided a method embodiment of a display method of a game screen.

Alternatively, in the present embodiment, the above-described display method of the game screen may be applied to a hardware environment constituted by the server 602 and the terminal 604 as shown in fig. 6. As shown in fig. 6, a server 602 is connected to a terminal 604 via a network, including but not limited to: the terminal 604 is not limited to a PC, a mobile phone, a tablet computer, etc. The game screen display method according to the embodiment of the present invention may be executed by the server 602, the terminal 604, or both the server 602 and the terminal 604. The terminal 604 may execute the game screen display method according to the embodiment of the present invention by a client installed thereon.

Fig. 7 is a flowchart of an alternative game screen display method according to an embodiment of the present invention, and as shown in fig. 7, the method may include the following steps:

step S702 is to obtain a first position of a first object in a first three-dimensional space, where the first three-dimensional space is a three-dimensional space where the first object is located in a plurality of three-dimensional spaces included in a game scene, and the first object is an object in the game scene.

The first object is an NPC object in a game scene, such as a prop of a player in the game, a prop in the scene (such as stars, moon, sun, mountain, water, river, field, etc.), and an NPC character (such as soldiers, auxiliary characters, pets, etc.).

The game scene is a game scene of a game, the game scene may be composed of a plurality of three-dimensional spaces, the game further includes a second object (i.e., an object controlled by a game account in the game), and the first three-dimensional space is a three-dimensional space in which the first object needs to be displayed and is also a three-dimensional space currently visible to the game account (player).

When the game is running in the client, the game engine (e.g., Unity) generates the game scene, and the camera captures a picture of the first three-dimensional space currently visible by the game account (step S704), and displays the picture.

Step S704, obtaining a target three-dimensional image to be mapped according to the original three-dimensional image of the first object, vertically mapping the target three-dimensional image to a target plane in the game scene to obtain a first two-dimensional image, obtaining a target two-dimensional image to be displayed according to the first two-dimensional image, where the size of the target two-dimensional image is related to the distance between the first position and the target plane, and the size of the target two-dimensional image is different from the size of a second two-dimensional image obtained by vertically mapping the original three-dimensional image to the target plane.

Alternatively, the "second two-dimensional image in which the size of the target two-dimensional image is different from the original three-dimensional image vertically mapped into the target plane" includes the following two meanings: one is that the size of the target two-dimensional image is smaller than that of the second two-dimensional image, namely the target two-dimensional image is obtained by reducing the second two-dimensional image; the size of the target two-dimensional image is larger than that of the second two-dimensional image, namely the target two-dimensional image is obtained by amplifying the second two-dimensional image. The following description will be given by taking a first mode (i.e., corresponding to a reduction) as an example, and a second mode is similar to the first mode.

As shown in fig. 8, the orthogonal mapping (orthogonal mapping, i.e. vertical mapping, is used in the game logic) is used in the present application, but in order to improve the reality of the object display, when the target three-dimensional image of the first object (such as a sphere) is mapped to the target plane to obtain the two-dimensional image, the perspective mapping effect needs to be achieved, and the mapping manner of the orthogonal mapping is not changed.

In the real environment, when an object is farther away from an observer, the image of the object is smaller, and the size of the first object mapped on the target plane is not changed when the target three-dimensional image is mapped on the target plane by adopting orthogonal mapping, so that the difference exists between the method adopting orthogonal mapping and the real image of the observed object.

The target plane is a plane of the first three-dimensional space facing the camera, and the distance between the plane and the camera is a preset closest distance allowing the game account to be observed; the other side opposite to the target plane is the farthest distance which is preset and allows the observation of the game account number, and the space between the two planes forms the first three-dimensional space.

Step S706, a target two-dimensional image mapped on the target plane is displayed.

The client of the game may be installed on a mobile terminal (e.g., a mobile phone, a tablet), a PC, a server, or the like, so that the target two-dimensional image is displayed on the client of the terminal.

In the technical scheme, the mapping mode (orthogonal mapping) of the game logic is not changed, so that the game logic does not need to be edited again, the perspective mapping effect can be achieved, the first object is displayed according to the mode meeting the perspective effect, and the first object is displayed according to the principle of 'far, small and near big' when displayed in the picture of the game animation, so that the situation that the whole picture is an object with equal size (such as stars and moonlights) is avoided, and the 'far, small and near big' display mode can show the layering sense on a two-dimensional plane, and further the game experience of a player can be improved.

Through the steps S702 to S706, obtaining a first position of a first object in a game scene in a first three-dimensional space, obtaining a target three-dimensional image to be mapped according to an original three-dimensional image of the first object, vertically mapping the target three-dimensional image to a target plane in the game scene to obtain a first two-dimensional image, obtaining a target two-dimensional image to be displayed according to the first two-dimensional image, wherein the size of the target two-dimensional image is related to the distance between the first position and the target plane; the target two-dimensional image mapped on the target plane is displayed, and because the size of the target two-dimensional image is different from that of a second two-dimensional image obtained by vertically mapping the original three-dimensional image on the target plane (namely, the target two-dimensional image is displayed according to a perspective mode of 'far-small-near-large'), when the first object is a star, the technical problem that the area of the game animation picture occupied by the star in the star sky scene in the related technology is too large can be solved, and the technical effects of reducing the area of the game animation picture occupied by the star and improving the reality of the game animation picture are achieved.

The technical solution of the present application is described in detail below with reference to the steps shown in fig. 7.

In the technical solution provided in step S702, the game scene may include a plurality of three-dimensional spaces, a first three-dimensional space in which a first object is located in the plurality of three-dimensional spaces is determined, and a first position of the first object in the first three-dimensional space is detected.

For the first object, there may be two cases, one of which is first present in the game scene at the current time and the other of which is already present in the game scene before the current time, and for the two cases, the method of acquiring the position may be different, and details are described below as to the configuration of the first object (when and in what form it is present in the game scene), how to acquire the position of the first object.

Configuration of a first object

Attribute information of each first object appearing in the first three-dimensional space is configured prior to acquiring a first position of the first object in the first three-dimensional space.

It should be noted that, in the present application, a plurality of object models (a small number, such as less than 10, or less than 20) may be predefined, and a plurality of colors for rendering the object models may be predefined. The role of the attribute information includes at least one of:

(1) the first object is indicated to be one of a plurality of preset objects which are randomly selected;

(2) for instructing to randomly select one from a plurality of preset colors for the first object;

(3) for indicating the first object to rotate randomly by an angle (including angles along the X-axis, the Y-axis, and the Z-axis) at the original position, so that the first object takes different shapes when facing the target plane, which is equivalent to indicating a random selection of one of the first object from a plurality of preset shapes;

(4) for indicating an initial distance between the first object and the target plane;

(5) for indicating the velocity vector (including the direction of motion and the magnitude of the velocity of motion) of the first object in the game scene.

(II) determining the position of the first object

(1) Case 1, the first occurrence in the game scene at the current moment

When the first object does not exist in the second three-dimensional space at the moment before the current moment, the first position configured for the first object in the first three-dimensional space is obtained, namely the first position is determined according to the initial distance between the attribute information and the target plane, the first three-dimensional space comprises the second object controlled by the game account number, the plane where the second object exists can be used as the target plane, namely the second object is always kept at the nearest end, and the control interaction of the game is facilitated.

The second three-dimensional space is a three-dimensional space in which the first object exists at a time immediately before the current time among the plurality of three-dimensional spaces.

(2) Case 2, having appeared in the game scene before the current time

And under the condition that the first object exists in the second three-dimensional space at the moment before the current moment, acquiring a second position of the first object in the second three-dimensional space, and determining a first position according to the second position and the moving speed of the first object, wherein the first object exists in the first three-dimensional space at the current moment.

As shown in fig. 8, if the speed direction of the first object indicated by the attribute information in the game scene is away from the camera along the Z-axis and the speed magnitude is V, the first position is different from its coordinates on the Z-axis only with respect to the second position, the changed coordinates are L — L0+ VT, L0 is the Z-axis coordinates of the second position, and T is the time difference between the current time and the previous time.

In the technical scheme of the application, the color, the angle, the initial distance and the velocity vector of the object model (such as the star model) with extremely small quantity are changed, so that the effect of 'starry sky' and different stars (size and color) can be realized, the model is prevented from being manufactured for each different star, and the art resources are saved; and in the game process, a large number of object models are prevented from being rendered, so that the game resources are saved.

In the technical solution provided in step S704, a target three-dimensional image to be mapped is obtained according to an original three-dimensional image of a first object, the target three-dimensional image is vertically mapped onto a target plane in a game scene to obtain a first two-dimensional image, a target two-dimensional image to be displayed is obtained according to the first two-dimensional image, a size of the target two-dimensional image is related to a distance between a first position and the target plane, and a size of the target two-dimensional image is different from a size of a second two-dimensional image obtained by vertically mapping the original three-dimensional image onto the target plane.

(one) shape and color with respect to mapping

In the above embodiment, the step of vertically mapping the target three-dimensional image onto the target plane in the game scene to obtain the first two-dimensional image may comprise the steps of:

in step S11, attribute information configured for the first object is acquired, the attribute information indicating a shape (which can be determined by the rotation angle indicated by the attribute information) and a color of the target three-dimensional image vertically mapped on the target plane.

Step S12, the target three-dimensional image is vertically mapped onto the target plane according to the shape and color indicated by the attribute information, resulting in a first two-dimensional image.

(II) size of the map

In the technical scheme of the application, the size of the finally obtained target two-dimensional image is related to the distance between the first position and the target plane through preprocessing before mapping and/or post processing after mapping, and the perspective display effect is achieved. The following description is made for these two implementations, respectively:

(1) pre-mapping preprocessing

Step S21, adjusting the size of the original three-dimensional image according to the distance between the first position and the target plane to obtain a target three-dimensional image, where the size of the target three-dimensional image is related to the distance between the first position and the target plane.

It should be noted that, the adjustment of the size of the original three-dimensional image may be an adjustment of the image itself, that is, the original three-dimensional image is scaled down to obtain the target three-dimensional image; or the first object can be scaled down and then rendered to obtain a target three-dimensional image.

Step S22, vertically mapping the target three-dimensional image onto a target plane to obtain a first two-dimensional image, and taking the first two-dimensional image as the target two-dimensional image.

Alternatively, the step S21 of "adjusting the size of the original three-dimensional image according to the distance between the first position and the target plane to obtain the target three-dimensional image" may be implemented as follows:

step S211, a first distance between the first position and the target plane is acquired.

Step S212, a reduction scale corresponding to the first distance is obtained according to a target relationship, wherein the target relationship is used for indicating a relationship between the distance between the position of the first object in the three-dimensional space and the target plane and the reduction scale.

Alternatively, the above target relationship may be described by the following relationship:

k ═ 1-Z/L, K denotes the reduction scale, Z denotes the first distance, and L denotes the farthest distance that the camera is allowed to capture (i.e., the farthest distance that the game account number sees), which can be used for the distance representation between that plane in the first three-dimensional space that corresponds to the target plane and the target plane.

Step S213, reduces the original three-dimensional image according to the reduction ratio corresponding to the first distance, to obtain the target three-dimensional image.

(2) Post-processing after mapping

In step S31, an original three-dimensional image of the first object is acquired as a target three-dimensional image.

Step S32, vertically mapping the target three-dimensional image onto the target plane to obtain a first two-dimensional image without changing the size of the first object.

Step S33, adjusting the size of the first two-dimensional image according to the distance between the first position and the target plane, to obtain a target two-dimensional image.

The step S33 of "adjusting the size of the first two-dimensional image according to the distance between the first position and the target plane to obtain the target two-dimensional image" may be implemented as follows:

in step S331, a first distance between the first position and the target plane is obtained.

Step S332, acquiring a reduction scale corresponding to the first distance according to a target relationship, where the target relationship is used to indicate a relationship between the distance between the position of the first object in the three-dimensional space and the target plane and the reduction scale.

Optionally, the target relationship may be described by the relationship, and the specific calculation manner is similar to that described above, and is not described herein again.

Step S333, the first two-dimensional image is reduced according to the reduction ratio corresponding to the first distance, and the target two-dimensional image is obtained.

In the technical solution provided in step S706, a two-dimensional image of the target mapped on the target plane is displayed.

As shown in fig. 9, when the first object is a star, in a general game, the background of the starry sky is generally realized by a sky box or a real art model, but due to the particularity of part of the game, orthogonal projection and a camera with a fixed angle are added, if the sky box is used, only the parallel movement of the starry sky background along with a character can be seen, and the depth sense (namely, near-fast and far-slow) of perspective projection in the subconscious of a player cannot be generated, and if the art resource is used, the manufacturing cost of art is very high, or the texture of the starry sky is very monotonous.

In the technical scheme of the application, simple resources for art manufacturing are used, perspective projection is simulated, grid mesh is automatically and randomly generated, and a starry sky background with perspective is formed.

For the glaring stars in the foreground, the method in the common game is to make frame animation, and the frame animation also has the problems of insufficient randomness and excessive resources. According to the scheme, a random shape and random flicker can be presented to the maximum extent by using simple resources according to the Alpha value in the art resources and the random time. Therefore, under orthogonal projection, the depth sense of the background starry sky and the shining effect of the foreground starry are realized.

As an alternative example, the following detailed description will be made of an implementation manner of the present application taking the first object as a star:

the game engine can select Unity, can edit in an editor of Unity, and can finish the technical scheme of the application by configuring parameters and preparing two maps.

The configuration of the starry sky in the corresponding script can adjust the effect of the art by changing the parameters of the script. The method can be adjusted during operation, and the stars can be adjusted by configuring material parameters.

As shown in fig. 10, parameters such as the initial number of stars, the initial size, the size attenuation (the ratio of each attenuation), the near-end distance (allowing the closest distance), the far-end distance (allowing the farthest distance), the color attenuation (e.g., fading, color fading), the moving speed of the camera, the initial position, and the material of the stars may be set.

As shown in fig. 11, on the star selection interface, one or more required stars may be selected from a plurality of star models of the star map, and the flicker amplification scale, the flicker frequency, and the Alpha channel value are configured, so that the same stars are configured differently to realize the full-sky stars and different stars.

The star and sky maps can be made by art, an optional star and star map in the sky is shown in fig. 12, Alpha channels in the maps are used, the color of the star map can be configured in the script, 9 shapes in the maps can be randomly selected from the codes, then a random rotation angle is added, and one of the colors configured by the art is randomly added.

An optional star map is shown in fig. 13, which has the shape of a star and can also carry information of Alpha values to be flashed. As described in detail below.

(1) Drift of starry sky and position in view window body are random

As shown in fig. 8, the position is first tied to the camera and an opposite relative velocity is added to the camera in each frame. This has a near-fast-far-slow effect, and since orthogonal projection is used in the game, i.e. the right side, it is difficult to show depth, and at this time, a perspective projection matrix M can be used for the space, so that the left side effect can be shown. The M matrix is as follows:

aspect denotes the projection plane (i.e. the aspect ratio of the object plane), fov denotes the angle of the view volume in the Z-axis direction, far denotes the distance from the far plane of the view volume to the focal point, near denotes the distance from the near plane of the view volume to the focal point.

Each piece of the starry sky is randomized to a position in the view volume space, and the three latitudes x, y and z are randomized.

For example, the coordinates of the star in the target space are (x1, y1, z1), and then the mapped coordinates are (x2, y2, z2), the mapping relationship between the two is: (x2, y2, z2, t2) ═ M (x1, y1, z1, t1) (M is the matrix), where t1 is an arbitrary number, such as 1. For the resulting (x2, y2, z2, t2), if mapped onto a plane, z2 and t2 can be left out, and x2, y2 are the desired coordinates.

(2) Space utilization of limited resources

In the foregoing, it is explained that the starry sky not only moves in reverse relative to the camera when the camera is moving, but also moves itself, and fragments of the starry sky may come out of view due to the movement of the starry sky.

Thus, the sky fragments are cut off, and in order to maintain the density of the sky fragments in the screen space, a large number of sky fragments are created in the whole game scene, so that the camera can see enough sky fragments when moving. However, doing so creates a significant overhead.

In order to reduce the amount of sky fragments, the present scheme does not actually generate as many sky fragments, although the positions of the sky fragments in the sky are always accumulated, as shown in fig. 14, the positions of the sky fragments are converted to the positions relative to the view volume during the actual rendering, and then the size of the view volume is modeled, so that the sky fragments are reset into the view volume after being moved out of the view volume, for example, for the star a, the star B and the star C are completely in the view volume, and the star fragments (partially in the view volume) after being converted and modeled. I.e. infinite starry sky is simulated with finite starry sky resources.

(3) Fading effect of starry sky

In order to simulate the effect of gradual hiding of starry sky from moving to a far place, the Alpha value of the fragments of the starry sky can be associated with the Z value, namely the farther the section is relative to the visual body, the lower the Alpha value of the fragments of the starry sky is, and the effect of gradual hiding of the starry sky from moving to the far place is further presented.

(4) Random algorithm of stars

As shown in fig. 15, in order to make the stars more realistic, the present solution randomly selects a star map from the previously described star maps, and then rotates a random angle, so that the real stars can be generated by using limited resources to the maximum extent, and different effects of the stars can be achieved (the small triangles and quadrilaterals in fig. 15 represent different stars).

(5) Sparkle of stars

Not only are the images of the stars varied, but they are also required to be glittering as in reality. The sparkle of a star includes a linear change in color value and an exponential change in Alpha. The change function Y of the exponent of Alpha is shown in FIG. 16 using X-axis time as the change parameter.

The x axis represents time, the y axis represents an alpha value, and the index is a function of a certain period of time which is flat and a certain period of time which is changed rapidly along with the time, so that the appearance of sudden twinkling of a star is met.

The change in color is linear, so that the luminance changes linearly with time, and the function is shown in fig. 17, where the X axis represents time and the Y axis represents luminance, and the luminance gradually increases and then gradually decreases with time, thereby showing a glittering effect.

As shown in fig. 18 and fig. 19, the starry sky is a very important part of the whole game, so that the player is in the air, and is the only scene of the game, and the texture of the starry sky is very important for the overall texture of the game, so that the experience of the player can be further improved after the starry sky is pushed out.
