The content of the invention will now be discussed with reference to a number of exemplary embodiments. It is to be understood that these examples are discussed only to enable those of ordinary skill in the art to better understand and thus implement the teachings of the present invention, and are not meant to imply any limitations on the scope of the invention.
As used herein, the term "include" and its variants are to be read as open-ended terms meaning "including, but not limited to. The term "based on" is to be read as "based, at least in part, on". The terms "one embodiment" and "an embodiment" are to be read as "at least one embodiment". The term "another embodiment" is to be read as "at least one other embodiment".
In the process of using the particle system to manufacture game resources in the related technology, because the vertex of the object model cannot have offset, if the vertex of the object model has offset, the position of the particle and the position of the particle in the process of particle dissipation generate offset, so that the particle cannot correctly sample the position of the vertex in the moving process, thereby generating offset dislocation and influencing the expected display effect of the game resources.
In order to solve the problem, this embodiment provides a method for making a game resource, as shown in fig. 1, where the method is applied to a client of a game resource making tool, and includes the following steps:
101. model deformation information output by the object model simulation game resources is obtained.
The making of game resources is an important link in the game generation process, the object model can be a model created for a game object according to the game scene requirements, the game object can be a game role, and can also be an element in a game scene, such as a tree, a mountain, a building and the like. In consideration of the situation that a game object often meets the application special effect in the middle of a game, a game scene has the production requirement of a large number of game resources, the game resources are equivalent to special effect expression, can be special effects of combustion and explosion, for example, the special effects of the game object after being attacked and the special effects of the game object after being exploded and the like. Here, the object model simulates the game resource, and the object model simulates the process of the resource special effect.
Specifically, in the process of simulating game resources by using the object model, a manufacturing tool with resource special effects may be used to simulate the resource special effects triggered from the vertices of the object model, and set attribute parameters of manufacturing the resource special effects, such as time parameters, position parameters, and region parameters of the resource special effects, which may include duration, trigger time, and the like of the resource special effects, and the position parameters may include the starting positions of the resource special effects on the object model, and the region parameters may include the trigger regions of the resource special effects in the game scene. Considering that simulation of a resource special effect triggered from an object vertex is accompanied by various vertex space transformations, so that model deformation is generated after the vertex of an object model is deviated, it is necessary to record attribute parameters related to the resource special effect to each vertex, summarize the attribute parameters recorded by the vertices of all object models, and output model deformation information.
102. And generating the vertex deformation of the object model according to the model deformation information, and baking the vertex deformation of the object model into a vertex animation chartlet.
The model deformation information is mainly position offset formed by spatial transformation of a vertex recorded after the object model is subjected to the resource special effect, the position offset can be expressed as a coordinate matrix of the vertex position, and the vertex deformation of the object model can be generated by using the position offset.
In particular, in baking vertex deformations into vertex animation maps for an object model, two modes can be used, one is a soft mode that does not change the topology of the object model, but records the position offset of the vertices with respect to the first frame position, and the other is a fluid mode that requires the introduction of a new object model. It can be understood that, in order to avoid introducing a new object model, a soft model is usually used, and the position offset amount is equivalent to the offset amount of the vertex in the coordinate space where the object model is located, i.e. the relative position offset of the vertex, at this time, the object model in the soft model cannot calculate the particle position by using the relative position offset amount, the position of the object model in the soft model can be placed at the origin in the first frame, so that the object model records the absolute position offset of the vertex in the soft model, derives the dynamic information map of the vertex according to the absolute position offset of the vertex, and forms the dynamic information of the vertex into a vertex animation map.
103. And reading the vertex offset data in the vertex animation map by using a particle system, and making a game resource of the object model according to the vertex offset data.
In a game scene, in order to realize a resource special effect which is separated from a real scope, for example, an instant movement, a magic effect, and the like, a particle system is needed to be used, particles are emitted through the particle system, and are controlled to move, zoom, rotate, and the like according to a specific mode, so as to realize different resource special effects, for example, a raindrop starts from a certain place in the air, then is continuously accelerated in a descending process under the influence of gravity, and finally falls on the ground to disappear. It will be appreciated that the use of only a single particle rarely satisfies the required resource special effects, and that most special effects resources, e.g. flames, smoke, require the production of hundreds or even thousands of particles, and that in order to control and maintain the production of a large number of particles, it is necessary to create emission resources in the particle system, which correspond to particle generators, which enable the production of particles from a certain location, and which control the number of particles produced, the initial velocity of the particles, the time of existence, and further attribute parameters.
Specifically, in the process of using the particle system, particles can be created based on vertex positions in the vertex animation maps, each vertex represents each particle in the particle system, and since the vertex offset data can represent the change condition of the object model generated in each frame in the process of simulating game resources, the vertex offset data in the vertex animation maps can be further read through the particle system, and the vertex offset data is used for controlling the particles to generate the resource effect of the game resources so as to realize the game resource production of the object model, wherein the trajectory curve, the running time, the running speed and the like of the particles in the running process can be controlled.
It can be understood that, since different game resources may produce different resource effects, different control manners need to be adopted for the particles formed by the vertices during the playing of the game resources by the particle system, to exemplify dissolving and dissipating game resources, dissolving and dissipating game resources need to control the particles during the playing of the particle system to realize different operating states, that is, from a flight state to a death state, the particles are alive when in the flight state and have opaque properties, and the particles disappear when in the death state and have transparent properties, and by controlling the transparency of the particles when in different operating states, dissolving and dissipating game resources can be realized for the game object.
Compared with the mode that the vertex of the object model can not generate offset in the current game resource manufacturing process, the method for manufacturing the game resource provided by the embodiment of the application simulates the game resource output by the game resource through the object model, generates the vertex deformation of the object model according to the model deformation information, cures the vertex deformation of the object model into the vertex animation model, reads vertex offset data in the vertex animation mapping by using a particle system, and manufactures the game resource of the object model according to the vertex offset data, and in the whole game resource manufacturing process, the simulated model deformation information and the vertex animation mapping are combined, when the object model has the vertex offset, the vertex offset data is acquired by using the particle system in the mode of sampling the vertex animation mapping, so that the accurate sampling and moving of the vertex position of the particle can still be ensured, and the vertex position is applied to game resource production, so that deviation errors are reduced, and the expected display effect of the game resources is improved.
Further, as a refinement and an extension of the specific implementation of the foregoing embodiment, in order to fully describe the specific implementation process of the embodiment, the embodiment provides another method for making game resources, as shown in fig. 2, the method includes:
201. and simulating the preset effect of the object model for displaying the game resources from the vertex by using the special effect tool, and acquiring the attribute parameters of the preset effect of the vertex display along with the change of time.
The special effect simulation tool can be a tool module embedded into game resource manufacturing software and has functions of simulating different game resource effects, such as a function of simulating a flame combustion effect, a function of simulating an explosion effect and the like. The preset effect is a simulated game resource effect, the attribute parameters of the vertex showing the change of the preset effect along with time at least comprise resource region parameters, resource position parameters, resource time parameters and resource change parameters which are set for the game resource effect, the resource region parameters at least comprise a triggering region of resources in a game scene, the resource position parameters at least comprise a resource starting position, a resource ending position and the like, and the resource time parameters at least comprise resource duration, resource triggering time and the like. Taking the simulated flame combustion effect as an example, a tool for manufacturing the combustion effect can be used for adding a fire source vertex to the object model, the dissipation effect of the object vertex is simulated after flame diffusion is manufactured through the fire source vertex, and the attribute parameters of the vertex dissipation effect changing along with time are set.
202. And calculating the starting time of the vertex display preset effect according to the attribute parameters of the vertex display preset effect changing along with the time.
It can be understood that, when the special effect simulation tool is used, because the time parameter for starting the game resource at each vertex is different, the number of starting frames of the game resource is recorded to the vertex, and by using the number of starting frames of the game resource and the total number of frames of the game resource, the starting time for showing the game resource at the vertex can be calculated, and the starting time can be used for controlling the playing speed of the game resource. Because the playing effect of the game resources is influenced by the model materials, particle materials generated by some model materials in the playing process of the game resources are not suitable for using slower speed parameters, and ion materials generated by some model materials in the playing process of the game resources need slower speed parameters, the model materials can be adjusted according to the preset effect of the game resources as required, and the starting time is controlled by setting the speed parameters of the model materials.
Specifically, the number of frames and the total number of frames when each vertex shows the preset effect can be obtained according to the attribute parameters of the vertex display preset effect changing along with time, the number of frames when each vertex shows the preset effect and the total number of frames are further divided, the starting time of the vertex display preset effect is obtained, the number of frames when the preset effect is shown can be obtained through calculation by a special effect simulation tool, the total number of frames can be defined by a user, the starting time is the time after normalization according to the total time of game resources, and the starting time can be used as the time for triggering the game resources by the object model.
203. And recording the starting time of the vertex displaying the preset effect to each vertex, and outputting model deformation information.
It can be understood that, in the process of the vertex displaying the preset effect, each vertex generates an animation, and each vertex corresponds to the start time, the vertex position change information generated by the vertex relative to the previous frame, and the like, where the start time is used as the start playing time for the object model to display the preset effect from the vertex, and the vertex position change information is triggered according to the start playing time to output the model deformation information.
Taking a display scene of a dissipation effect as an example, firstly inputting an object model needing to be manufactured with the dissipation effect, rearranging through a triangular surface and adding a combustion peak, simulating a flame diffusion effect through a combustion node, acquiring a total frame number of combustion and a frame number during dissipation of combustion, dividing the frame number during dissipation of combustion and the total frame number, calculating the percentage of the starting time of each peak to the total duration, normalizing the starting time, recording the normalized starting time to each peak, and outputting model deformation information.
204. And generating the vertex deformation of the object model according to the model deformation information, and baking the vertex deformation of the object model into a vertex animation chartlet.
The model deformation information records an offset value generated when the vertex shows the preset effect, and the offset value is not the absolute position offset of the vertex deformation but the position offset generated relative to the object model, and specifically, the model deformation information is read in the material to obtain vertex offset data, the vertex offset data is superposed on the world position offset of the vertex to generate the vertex deformation of the object model, and the vertex deformation of the object model is baked into the vertex animation chartlet.
In order to facilitate reading of the model deformation information, the model deformation information formed by the vertex animation can be recorded in the map, so that the vertex offset data can be obtained by reading the pixel values of the map in the material, and the vertex deformation of the object model can be generated by superposing the vertex offset on the world position offset of the vertex.
205. And determining the transparency of different luminosity areas mapped by the preset effect by comparing the starting time of the vertex display preset effect with the current playing time.
It should be noted that, considering the visibility of the vertex display preset effect, whether the vertex preset effect is triggered for display, and whether different luminosity changes are required after the triggering for display, the control is performed according to the playing time, the display of the preset effect is required to be triggered when the current playing time reaches the starting time, and after the current playing time is longer than the starting time, the preset effect also needs to use different luminosity changes in the display process, namely, a luminous area and an opaque mask area are used, different luminosity areas can be determined in the material, the different luminosity areas are controlled by using the transparency, and the object model can display the preset effect of the game resource by controlling the transparency of the different luminosity areas.
The different luminosity regions can be regions with different brightness generated around the vertex when the preset effect is displayed, for the preset effect in a circle shape, the luminosity region size can be controlled by using a width value, for example, a circle of special effect similar to flame is needed for a dissipation edge, and the luminosity regions with different flame effect mapping need to be determined. In general, the luminance of the light region is higher the closer the distance vertex is.
206. And if the starting time for displaying the preset effect on the vertex is shorter than the current playing time, adjusting the transparency of different luminosity areas mapped by the preset effect.
Specifically, in the material, since the starting time is the time when the preset effect starts to be displayed, if the starting time when the vertex displays the preset effect is shorter than the current playing time, it is indicated that the vertex is affected by the preset effect, and then the transparencies of different luminosity areas mapped by the preset effect are adjusted, so that the vertex can accurately display the preset effect for the game resources. For example, for a game resource of the dissipation special effect, different luminosity regions mapped by the preset effect can be set to be transparent, and the width of the bright edge region is controlled by using the preset width value, so that the vertex can show the dissipation special effect.
It should be noted that, when the vertex shows the preset effect, since the first frame of the vertex animation map is already pressed to the origin, the distance between the vertices of the object model may be too small, and at this time, the triangle surface is not generated, but the vertex needs to be played from the second frame when the preset effect is shown.
207. And acquiring two pieces of texture coordinate information of the vertex animation map mapped to the surface of the object model according to the vertex offset data in the vertex animation map.
In this embodiment, in order to implement model deformation by using the vertex animation map, before obtaining two texture coordinate information mapped to the object model surface by the vertex animation map, the particle system needs to use two emission resources, where two emission resources may be set in the particle system, and are respectively used for emitting particles showing a preset effect and controlling a model material to show the preset effect. For example, for dissolving and dissipating game resources, one emission resource is used for emitting spark particles to the air, and the other emission resource is used for controlling the dissolving effect of the model material. It can be understood that, while using two transmission resources, two pieces of texture coordinate information mapped to the surface of the object model by the vertex animation map need to be obtained, where one piece of texture coordinate information is used to control the object model to exhibit the preset effect, and the other piece of texture coordinate information is used to control the animation playback during the process of the vertex exhibiting the preset effect.
Because the vertex animation chartlet is the position for vertex deformation, each vertex has corresponding texture coordinate information, and one texture coordinate information is an array, the starting time for displaying the preset effect on the vertex and the sampling coordinate of the vertex animation chartlet can be obtained by using a node for reading the texture coordinate information, and then the vertex dynamic chartlet is sampled by using the sampling coordinate of the vertex animation chartlet, and two pieces of texture coordinate information mapped to the surface of the object model by the vertex animation chartlet are obtained.
Further, since each particle initially records its corresponding vertex position, and texture coordinate information of the vertex mapped to the surface of the object model is also determined, the vertex animation map can be sampled by scrolling the texture coordinate information in the particle system. To simplify the sampling process, the vertices can also be placed in a row when storing the vertex deformation, and the row number can be directly increased to read the vertex animation map.
208. And reading two pieces of texture coordinate information mapped to the surface of the object model by using a particle system, and manufacturing a game resource of the object model by sampling the two pieces of texture coordinate information.
Specifically, the particle system can be used for reading two texture coordinate information mapped to the surface of the object model by the vertex animation mapping, the starting time of the vertex display preset effect and the deformation position of the vertex are obtained, on one hand, the starting time of the vertex display preset effect is utilized, the execution speed of the control model material display preset effect is controlled, the execution speed of the current particle system playing time value control model material display preset effect can be transmitted into the material, on the other hand, the deformation position of the vertex is utilized, the particle display preset effect operation track is controlled, and the operation track of the preset effect can be controlled through sampling the coordinates of the deformation position of the vertex.
It should be noted that, because the GPU particles are used in the particle system, and the GPU particles cannot read the data of the previous frame, and cannot continuously track the particles of the same identifier, the identifier of the particle between two frames may be confused, thus, the problem that the particle information between two frames cannot be synchronized is generated, here, the particles showing the preset effect can be generated at the vertex of the object model, the opacity of the particles is controlled by using the playing time of the particle system, so that when the playing time is consistent with the time recorded by the two texture coordinate information, the transparency of the particles is updated, and controlling the continuous operation state of the particles to switch the operation state when a preset condition is satisfied, wherein the preset condition can be an attribute parameter set for the particles to show a preset effect, there may be a survival time, in which the flight state continues as long as the particle survival time is greater than the start-up time.
By way of example of game resources showing the dissolving and dissipating effect, all particles can be generated on the model vertex at the beginning of the particle system, the opacity of the particles is controlled through the playing time of the particle system, so that the particles which are not started are invisible, when the playing time is consistent with the time recorded by two pieces of texture coordinate information of the surface of the object model, the particles are set to be opaque, meanwhile, the particles are set to be in a flying state, and as long as the survival time of the particles is longer than the starting time, the flying state is continued until the particles die, and the dissolving and dissipating effect is completed.
Furthermore, in order to independently control the effect of the particles, the flight times of the particles are recorded small in addition to the life cycle of the particles, so that different game resources are created for the particles, for example, a game resource in which ash turns black, a game resource in which the particles revive, and the like are created.
