Description

The visual effect class that references an VisualEffectAsset instance within the Scene.

Properties

aliveParticleCountReturns the sum of all alive particles within the visual effect.
culledUse this property to determine if this visual effect is not visible from any Camera. (Read Only)
initialEventIDThe default event name ID. To retrieve this value, use the Shader.PropertyID after VisualEffect has awakened or after you've invoked VisualEffect.Reinit.
initialEventNameThe default event name. Unity calls this event when the VisualEffect awakes, or when you call VisualEffect.Reinit.
outputEventReceivedOutput event are reported trough this callback.
pauseUse this property to set the pause state of the visual effect.
playRateA multiplier that Unity applies to the delta time when it updates the VisualEffect. The default value is 1.0f.
resetSeedOnPlayThis property controls whether the visual effect generates a new seed for the random number generator with each call to VisualEffect.Play function.
startSeedThe initial seed used for internal random number generator.
visualEffectAssetThe VisualEffectAsset that the VisualEffect uses.

Constructors

VisualEffectThe VisualEffect constructor.
