sdlxSetGpuRenderStateStorageBuffers function render

bool sdlxSetGpuRenderStateStorageBuffers(Pointer<SdlGpuRenderState> state, List<Pointer<SdlGpuBuffer>> storageBuffers)

Set storage buffers variables in a custom GPU render state.

The data is copied and will be binded using SDL_BindGPUFragmentStorageBuffers() during draw call execution.

\param state the state to modify. \param num_storage_buffers The number of storage buffers to bind. \param storage_buffers Storage buffers to bind. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should be called on the thread that created the renderer.

\since This function is available since SDL 3.6.0.

extern SDL_DECLSPEC bool SDLCALL SDL_SetGPURenderStateStorageBuffers(SDL_GPURenderState *state, int num_storage_buffers, SDL_GPUBuffer *const *storage_buffers)
