Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. However, those skilled in the art will recognize that the aspects of the present disclosure may be practiced with one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

In the related art, the virtual flame is an integral body, and the virtual flame effect as shown in fig. 1 is presented by controlling the size of the virtual flame in the z direction to match the spraying distance; and determining an injection target point through the injection direction of the injection port coordinates of the flame injector so as to judge the injury scope and determine the injury effect. Obviously, in the process, the virtual flame generation logic and the injury effect determination logic are mutually independent, and the phenomenon that an enemy virtual object is not burned visually and injury is caused easily occurs, so that the sense of reality of the virtual flame is reduced, and the user experience is poor.

In view of one or more of the problems described above, exemplary embodiments of the present disclosure first provide a virtual flame generating method. The system architecture of the operating environment of the present exemplary embodiment is described below in conjunction with fig. 2.

Referring to fig. 2, a system architecture 200 may include a terminal device 210 and a server 220. The terminal device 210 may be an electronic device such as a notebook computer, a tablet computer, or a desktop computer, and the terminal device 210 may be configured to obtain a position and a spraying direction of the flame sprayer. The server 220 generally refers to a background system that provides a virtual flame generation-related service in the present exemplary embodiment, and may be, for example, a server that implements a virtual flame generation method. Server 220 may be a server or a cluster of servers, which is not limited by this disclosure. The terminal device 210 and the server 220 may form a connection through a wired or wireless communication link for data interaction.

The virtual flame generation method in the present exemplary embodiment may be performed by the terminal device 210. For example, in a game scenario, the terminal device may be a computer running a game, and when a flame injector in the game is triggered to inject a flame effect, the terminal device 210 may obtain a position of a collidable virtual fire group according to a position and an injection direction of the flame injector in the game scenario by performing a virtual flame generation method, and determine and display an injury effect of the virtual flame on an assailable object when the collidable virtual fire group contacts the assailable object in the game.

In one embodiment, in response to an emission instruction for a flame injector in a game, the position and the injection direction of the flame injector may be acquired in real time by the terminal device 210 and transmitted to the server 220, and after receiving the position and the injection direction of the flame injector, the server 220 may acquire the positions of a plurality of collidable virtual fire groups according to the position and the injection direction of the flame injector and insert one or more collision-free virtual fire groups between the collidable virtual fire groups, form a virtual flame based on the collidable virtual fire groups and the collision-free virtual fire groups, determine an injury effect of the virtual flame on the attackeable object in the case that the collidable virtual fire groups contact the attackeable object in the game, and transmit the injury effect to the terminal device 210 for display.

As can be seen from the above, the virtual flame generating method in the present exemplary embodiment may be performed by the terminal device 210 or the server 220 described above.

The virtual flame generation method will be described with reference to fig. 3. Fig. 3 shows an exemplary flow of the virtual flame generation method, including the following steps S310 to S330:

step S310, responding to an emission instruction of a flame ejector in a game, and acquiring a plurality of positions of the collidable virtual fire groups according to the positions and the spraying directions of the flame ejector;

step S320, inserting one or more collision-free virtual fire groups between the collision-free virtual fire groups, and forming virtual flames based on the collision-free virtual fire groups and the collision-free virtual fire groups;

in step S330, in the case that the collidable virtual fire group contacts the attackeable object in the game, an injury effect of the virtual flame on the attackeable object is determined.

Based on the method, on one hand, under the condition that the collidable virtual fire group contacts an attackeable object in the game, the damage effect of the virtual flame on the attackeable object is determined, compared with the mode that the generation logic of the virtual flame and the damage effect determination logic corresponding to the virtual flame in the prior art are mutually independent, the virtual flame matched with the damage effect is generated, the sense of reality of the virtual flame is effectively improved, and the sense of immersion of a user in the game is improved; on the other hand, a collision-free virtual fire group is inserted between the collision-free virtual fire groups to form virtual flames, so that the system operation pressure is effectively reduced and the system operation efficiency is further improved while the virtual flames matched with the injury effect are generated; in yet another aspect, a virtual flame is formed using the collidable virtual fire group and the collision-free virtual fire group, and multiple virtual flames can be formed by adjusting the collidable virtual fire group and the collision-free virtual fire group, so that flexibility and diversity of the virtual flame are improved, and user experience is further improved.

Each step in fig. 3 is specifically described below.

Referring to fig. 3, in step S310, in response to an emission instruction for a flame injector in a game, positions of a plurality of collidable virtual fire groups are acquired according to the positions and the injection directions of the flame injector.

Wherein the flame ejector may be a virtual weapon for ejecting flames in a game, the collidable virtual fire group is provided with a collider for constituting the virtual flames ejected by the flame ejector, and it is determined whether the virtual flames contact an offensive object by collision detection. The attacked object may be a virtual object in the game, for example, the attacked virtual object may include an opponent game character in a game, and may also include a virtual house, virtual lawn, etc. in the game that may be "burned".

The virtual fire groups are bound with the collision body to obtain the collidable virtual fire groups which can be used for collision detection, and the positions of a plurality of collidable virtual fire groups are obtained according to the positions and the spraying directions of the flame sprayers, so that the sense of reality of virtual flames formed by the collidable virtual fire groups can be effectively improved.

Since a collision body with a corresponding size is bound to each virtual fire group, a great performance pressure is brought to the electronic device running the game, and the game effect is affected, in order to fill the fire column density sprayed by the flame sprayer and reduce the performance consumption, with continued reference to fig. 3, step S320, one or more collision-free virtual fire groups are inserted between the collision-free virtual fire groups, and virtual flames are formed based on the collision-free virtual fire groups and the collision-free virtual fire groups.

The collision-free virtual fire group is an unbound collision body and has a virtual geometric body with the same display effect as the collision-free virtual fire group, namely, the collision-free virtual fire group can not trigger the injury effect when contacting an attackeable object.

Referring to fig. 4, real_pellet represents a collidable virtual fire group, pick_pellet represents a non-collided virtual fire group, and the non-collided virtual fire group is arranged between the collidable virtual fire groups, so that a virtual flame effect with low performance consumption and strong sense of realism can be obtained.

In order to generate a dynamic virtual flame, in one embodiment, the method may further comprise the steps of:

the location of the collision free virtual fire mass is updated based on the location of the collidable virtual fire mass.

The position of the collision-free virtual fire group is updated through the position of the collision-free virtual fire group, so that the position of the collision-free virtual fire group is consistent with the position of the collision-free virtual fire group, and a continuous virtual flame effect is formed, so that the generated virtual flame does not suddenly disappear in the moving process of the flame ejector, but has a flame tailing effect, and a dynamic virtual flame with stronger sense of reality is obtained; in the process of determining the virtual fire group position, the position of the collision-free virtual fire group does not need to be recalculated according to the position determining method of the collision-free virtual fire group, so that the code repeatability is reduced, the code readability is further improved, and the running pressure of a system is effectively reduced.

In one embodiment, the updating the location of the collision-free virtual fire group based on the location of the collidable virtual fire group may include the steps of:

updating the flight position of the collision-free virtual fire group according to the flight position of the collision-free virtual fire group under the condition that the emission position of the collision-free virtual fire group is the same as the emission position of the following collision-free virtual fire group;

wherein the emission orientation may include an emission position and an emission direction of the flame injector when the flame injector emits the virtual fire mass, and the emission position may include an emission position of the flame injector or a position of the flame injector; the same emission orientation means that the flame injector does not change its injection position and injection direction during the process of emitting the collision-free virtual fire mass and the collidable virtual fire mass that follows it.

For example, in the case that the emission direction of the collision-free virtual fire group is the same as the emission direction of the following collision-free virtual fire group, gravity, damping, friction, and the like may be set for the collision-free virtual fire group in advance according to preset parameters, then the emission position of the collision-free virtual fire group is determined according to the position of the flame injector, the emission direction of the collision-free virtual fire group is determined based on the emission direction of the flame injector, after the collision-free virtual fire group is emitted, the flight position information of the collision-free virtual fire group is obtained in each frame of game scene, and the flight position information of the collision-free virtual fire group is stored by using a circulation queue. In order to store the position information of the collidable virtual fire groups in the circulation queue, the real_pellet represents the collidable virtual fire groups, the check_pellet represents the non-collided virtual fire groups, the real_pellet is set to have a jet speed of t seconds, x check_pellets are uniformly distributed between two real_pellets, the flight paths of the real_pellets are recorded according to the frequency f times per second, t/(x+1) f coordinate point information can be obtained between adjacent virtual fire groups, the "distance" between the real_pellet and the last check_pellet is t/(x+1) f x coordinate point information, and the maximum length of the circulation queue can be determined according to the following formula (1):

max_length ＝ t * x * f / (x + 1) + 3 (1)

Wherein max_length is the maximum length of the circular queue, and 3 is the preset error compensation value.

After determining the maximum length of the circular queue, the flight position of real_pellet may be written into the circular queue according to the following code:

queue [ tail ] = position// store position at position with queue index of tail

Tail= (Tail+1)% max_length// calculate position Tail stored next position from max_length

Where queue represents a circular queue, position may represent the flight position of real_bullets, and tail represents the index in the queue.

After the flight position of the collidable virtual fire group real_pellet is written into the cyclic queue, the flight position of the collision-free virtual fire group trick_pellet can be determined according to the flight position of the real_pellet stored in the queue.

In the case that the emission orientation of the collision-free virtual fire group is different from the emission orientation of the collidable virtual fire group which it follows, if the flight position of real_pellet in the queue is directly used as the flight position of the following trick_pellet, as shown in fig. 5, the phenomenon that the flame injector rotates while the collision-free virtual fire group trick_pellet still flies following the collidable virtual fire group real_pellet occurs, and in the actual game scene, the virtual flame effect shown in fig. 6A and 6B occurs, wherein fig. 6A shows that the virtual flame is still ejected from the position before the flame injector moves when the flame injector moves longitudinally, and fig. 6B shows the phenomenon that the virtual fire group is scattered throughout the scene when the flame injector turns laterally.

Thus, in the event that the emission orientation of the collision free virtual fire mass differs from the emission orientation of the collidable virtual fire mass that it follows, the flight direction and flight position of the collision free virtual fire mass are updated in accordance with the first emission orientation of the collidable virtual fire mass and the second emission orientation of the collision free virtual fire mass.

Wherein, the different emission directions refer to that the flame injector changes the injection position and the injection direction in the process of emitting the collision-free virtual fire mass and the collision-free virtual fire mass which is followed by the flame injector.

Compared with the prior art that when the virtual flame is taken as a special effect whole, when the flame ejector moves, the vanishing effect of the virtual flame is more abrupt, and in the present exemplary embodiment, the flight position and the flight direction of the collision-free virtual flame are updated according to the position of the collision-free virtual flame according to the situation, so that when the virtual flame is sprayed and turned once, the residual effect of the virtual flame is realized, and the sense of reality of the virtual flame is further improved.

In one embodiment, the first emission direction includes a first emission direction and a first emission position, the second emission direction includes a second emission direction and a second emission position, and updating the flight direction and the flight position of the collision-free virtual fire group according to the first emission direction of the collision-free virtual fire group and the second emission direction of the collision-free virtual fire group, as shown in fig. 7, may include steps S710 to S720:

Step S710, determining a flight direction offset according to the first emission direction and the second emission direction, and determining a flight position offset according to the first emission position and the second emission position;

in step S720, the flight direction is determined based on the second emission direction and the flight direction offset, and the flight position is determined based on the second emission position and the flight position offset.

The flight direction offset is used for determining a specific value of the flight direction of the collision-free virtual fire group needing to be offset on the basis of the second emission direction, and the flight position offset is used for determining a specific value of the flight position of the collision-free virtual fire group needing to be offset on the basis of the second emission position.

For example, when the real_pellet is launched by the collidable virtual fire group, recording a first launching position fire_pos and a first launching direction fire_forward corresponding to the real_pellet, and continuously writing a flight path of the real_pellet into the circular queue; when each trigger_pellet following the real_pellet emits, a second emission position fire_pos 'and a second emission direction fire_forward' corresponding to the trigger_pellet can be obtained (the second emission position and the second emission direction are the current position and the current injection direction of the flame injector); the flight position offset position_offset can be calculated according to fire_pos and fire_pos ', and the flight direction offset rotation_offset can be calculated based on fire_forward' and fire_forward; finally, according to the fire_pos 'and the position_offset, the flight position of the non-collision virtual fire group, namely the fire_position, of the fire_button can be obtained, according to the fire_forward' and the rotation_offset, the flight direction, namely the fire_button, of the non-collision virtual fire group can be obtained, according to the fire_position and the fire_button_forward, the position representation of the fire_button is updated, namely the flight direction of the fire_button is changed from the first emission direction to the second emission direction when the first emission direction is different from the second emission direction, in an actual game, the virtual flame effect shown in fig. 9 can be achieved, and according to fig. 9, after the flame ejector rotates transversely, the virtual flame does not move along with the flame ejector in a sharp manner, but the flame effect is shown in the second emission position with the flame tailing effect.

Based on the method of fig. 7, the second emission direction and the second emission position are modified based on the flight direction offset and the flight position offset, so that the problem that the virtual flame changing process is too abrupt when the orientation of the flame injector is changed is solved, the sense of reality of the virtual flame is further enhanced, and the sense of immersion of a user in a game is effectively improved.

For a more realistic and lively virtual flame, the size of the virtual flame may be modified over time of flight, exhibiting the effect that each bolus of virtual flame is visually constantly "diffuse", "expand", in one embodiment the method may further comprise:

and in a preset fire group change period, adjusting the size of the collidable virtual fire group and the size of the non-collided virtual fire group so as to form a virtual flame with the size changing along with time.

The duration of the preset fire group change period is not particularly limited, and for example, the preset fire group change period may be 3 seconds.

By modifying the size of the collidable virtual fire group and the size of the collision-free virtual fire group within the preset fire group change period, the effect that each group of virtual flame is continuously changed can be presented, so that the whole effect of the generated virtual flame is more natural and has more realism.

In one embodiment, the adjusting the size of the collidable virtual fire group and the size of the non-collided virtual fire group within the preset fire group variation period, as shown in fig. 10, may include steps S1010 to S1020:

step S1010, acquiring a fire bolus size minimum value and a fire bolus size maximum value, wherein the fire bolus size minimum value is selected from a preset fire bolus size minimum range, and the fire bolus size maximum value is determined according to the sum of the fire bolus size minimum value and a fire bolus size increment, and the fire bolus size increment is selected from a preset fire bolus increment range;

in step S1020, in the preset fire group variation period, the size of the collidable virtual fire group and the size of the non-collided virtual fire group are adjusted from the minimum fire group size to the maximum fire group size.

The preset fire ball size minimum range may be a variation range of a fire ball size minimum value, and the preset fire ball increasing amount range may be a variation range of a fire ball size increasing amount.

For example, the minimum range of the size of the fire cluster may be represented by [ min_scale_left_boundary, min_scale_right_boundary ], where min_scale_left_boundary and min_scale_right_boundary represent the minimum value and the maximum value of the minimum value of the size of the fire cluster, respectively, and a random value may be selected from the minimum range of the size of the fire cluster as the minimum value of the size of the fire cluster of the collidable virtual fire cluster or the non-collidable virtual fire cluster, min_scale; the preset fire group increment range may be represented by [ add_scale_left_boundary, add_scale_right_boundary ], wherein add_scale_left_boundary and add_scale_right_boundary may represent a minimum value and a maximum value of the fire group size increment, respectively, and a random value may be selected as the fire group size increment add_scale of the collidable virtual fire group or the non-collidable virtual fire group in the preset fire group increment range; the fire size maximum max_scale may be determined according to equation (3):

max_scale ＝ min_scale + add_scale (3)

When the fixed value change_duration is used to represent the preset fire group change period, referring to fig. 11, in the change_duration time after each collidable virtual fire group or non-collidable virtual fire group is emitted, the size of the virtual fire group can be uniformly changed from its corresponding min_scale to max_scale, and since the min_scale and add_scale of each virtual fire group are random values within the preset range, the min_scale and the max_scale of each virtual fire group are different, so as to present the effect that the size of each virtual fire group is different in the flame flight process.

Based on the method of fig. 10, the effect that the size of the virtual flame gradually becomes larger in the duration of the flame being sprayed is achieved, and meanwhile, the size of the virtual flame can be adjusted according to the size of each virtual fire group, so that the generation process of the virtual flame is more flexible, and meanwhile, the richness and diversity of the virtual flame are improved.

With continued reference to fig. 3, in step S330, in the event that the collidable virtual fire group contacts an assailable object in the game, the damaging effect of the virtual flame on the assailable object is determined.

The injury effect may include a "burning" effect generated by the virtual flame on the attacked object, and the specific expression form of the injury effect is not particularly limited in the present disclosure, and exemplary, the injury effect may include a continuous decrease of a life value of the attacked virtual object.

For example, it may be determined whether the collisionable virtual fire is in contact with an offensive object in the game according to the following procedure: setting the position of the jet orifice of the flame jet as fire_pos, setting the fire jetting direction as fire_direction, and setting the current flame jetting distance as fire_distance, wherein the target point end_pos=fire_pos+fire_direction of flame jetting is fire_distance; after determining the end_pos, the end_pos can be shifted by a preset flame diffusion value along the upper left, upper right, lower left and lower right directions to obtain 4 target shift points; performing ray detection by taking the position of the jet orifice as fire_pos as a starting point and taking 4 target offset points as end points to determine the distance between the jet orifice and the target offset points, and determining an injury range max_dist according to the maximum value in the distances; the collidable virtual fire mass may perform a collision translation detection with fire_pos as a starting point and fire_pos+fire_direction max_dist as an ending point, so as to detect a contacted attacked virtual object in a process of moving the collider from the starting point to the ending point.

Since the "false fire" does not trigger the settlement of injury, it may happen that the player clearly sees that the flame injector controlled by himself "hits" the attackeable virtual object, but does not cause injury to the virtual object, and thus, in one embodiment, the above-mentioned injury effect may include the sum of injury values, and the above-mentioned determination of the injury effect of the virtual flame on the attackeable object may include the following steps:

And determining an actual display injury value according to the quotient of the injury numerical value sum and the preset display frequency, and displaying the actual display injury value according to the preset display frequency to determine an injury effect.

Wherein the injury value sum may be a specific value that characterizes the virtual flame's reduction in life value for the offensive virtual object, e.g., the injury value sum may be 80; the preset display frequency may represent a specific display number of actual injury values, and the method and the specific numerical value for obtaining the preset display frequency are not particularly limited, and by way of example, the preset display frequency may be a random value within a certain numerical range, and the preset display frequency may be 4; the actual display of the injury value may be used to present the virtual flame to the user to achieve a multiple injury effect on the attacked object.

For example, the sum of the injury values may be 80, and the preset display frequency may be 4, and the actual displayed injury value 20 may be displayed for 4 times in the time when the virtual flame contacts the attacked virtual object.

The damage numerical sum is displayed for a plurality of times, so that the situation that the flame injector 'hits' the attacked virtual object but does not damage the virtual object is improved, and the sense of reality and the accuracy of the damage effect of the virtual flame on the attacked object are improved.

Based on the above method, the flame effect as shown in fig. 12A, 12B and 12C can be simultaneously realized with ensured low performance overhead, wherein fig. 12A shows the effect that the virtual flame size changes with time, fig. 12B shows the effect of "air-remaining" of the virtual flame when the flame injector turns longitudinally, and fig. 12C shows the effect of "air-remaining" of the virtual flame when the flame injector turns transversely, and it can be seen that the above method generates a more realistic, flexible and accurate virtual flame.

The exemplary embodiment of the disclosure also provides a virtual flame generating device. As shown in fig. 13, the virtual flame generating apparatus 1300 may include:

a position determination module 1310 of the collidable virtual fire group, configured to acquire a reference expression model of the reference face and a sample expression model of the target face, and establish a variable of the reference expression model and a variable of the weight of the target face;
