Methods

_swapHDRFrontAndBack()

Child classes need to call this when rendering to and from full-resolution textures. This will effectively swap hdrSource and hdrTarget to allow ping-ponging.

Inherited From:

bindListener()

Listens to the entity's messenger for a given message type.

Inherited From:

broadcast()

Broadcasts a message dispatched by the owning Entity's onMessage Signal.

Inherited From:

clone()

Creates a duplicate of this Component.

Inherited From:

hasListeners()

Tests whether the given signal is being listened to.

Inherited From:

invalidateBounds()

Marks the bounds as invalid, causing them to be recalculated when next queried.

Inherited From:

isSupported()

Indicates whether this Effect is supported considering the current capabilities. Subclasses should overwrite this if support depends on extensions.

Inherited From:
