Function: createRenderEcsSystem()
createRenderEcsSystem(
renderContext):EcsSystem<[CameraEcsComponent,PositionEcsComponent],void,RenderPassResult>
Defined in: rendering/systems/render-system.ts:255
Creates a render system that batches and renders sprites based on the camera view.
Each camera draws into its own CameraEcsComponent.renderTarget, or
directly onto the canvas if it doesn't have one, clearing that
destination first (according to RenderContext.clearStrategy) the first
time it's used each frame. Cameras that share a destination (either the
canvas or the same RenderTarget) draw on top of one another rather than
each clearing what the last one drew.
run gathers each camera's sprite commands and projection matrix without
drawing anything; afterRun does the actual drawing, once every camera
has run, so every camera's batches are issued from a single, predictable
pass over the whole tick's results.
Parameters
renderContext
The rendering context
Returns
EcsSystem<[CameraEcsComponent, PositionEcsComponent], void, RenderPassResult>
The render ECS system
