public final class RenderSystem
extends GameSystem

Manages the order of rendering. Everything, except the UI, is rendered through this system. Layers are ordered by "z-index", from lowest to the highest (higher z-index is being drawn on top of a lower ones). Default systems add their (default) layers with z-index specified in config.GameRenderingOrder. By default, LayerRenderers will receive an instance of Batch which is already prepared to be used (batch.begin() already called, color set to WHITE, previous layers are flushed if needed, projection and transform matrices are reset to camera / zero, blending is enabled and "additive" color mode is set to the value specified by the layer) and it guarantees that this batch has not been affected by the previous layers. It is not necessary to use this instance of batch and it can be completely ignored - batch is there for a convenience, other rendering methods (ShapeRenderer / PolygonBatch / SpriteCache etc) can be used instead but LayerRenderer must properly configure them manually (make sure to set a proper color / matrices etc). Layers can do whatever they need to in their LayerRenderers - for example, switch a shader / end the batch, use ShapeRenderer instead, start rendering to FrameBuffers (using RenderManager's methods) etc.

Description copied from interface: com.badlogic.gdx.utils.Disposable

Releases all resources of this object.

Specified by:

dispose in interface Disposable

Overrides:

dispose in class GameSystem

getLayer

@Null
public RenderSystem.Layer getLayer(int zIndex)

removeLayerByZIndex

@Null
public RenderSystem.Layer removeLayerByZIndex(int zIndex)

removeLayer

@Null
public RenderSystem.Layer removeLayer(RenderSystem.Layer layer)

calculateDeltaTimes

public void calculateDeltaTimes(Render event)

drawLayers

public void drawLayers(Batch batch)

prepareBatch

Does the same as RenderingManager.prepareBatch but also resets projection / transform matrix to the current camera (in case it has been changed)

profileUpdate

public boolean profileUpdate()

Description copied from class: GameSystem

Should the update() method be rendered on the debug overlay

Overrides:

profileUpdate in class GameSystem
