生成系统的生成状态。
This class is useful for debugging a Visual Effect's spawner. For example, you can see if the effect is currently playing, the number of loops the spawner has processed, as well as the current state of the spawner.
To access the state of a Visual Effect's Spawn system, either use VisualEffect.GetSpawnSystemInfo or, in a class that inherits from VFXSpawnerCallbacks, override the OnUpdate method.
using UnityEngine; using UnityEngine.VFX;
class ConstantRateEquivalent : VFXSpawnerCallbacks { public class InputProperties { [Min(0), Tooltip("Sets the number of particles to spawn per second.")] public float Rate = 10; }
static private readonly int rateID = Shader.PropertyToID("Rate");
public sealed override void OnPlay(VFXSpawnerState state, VFXExpressionValues vfxValues, VisualEffect vfxComponent) { }
public sealed override void OnUpdate(VFXSpawnerState state, VFXExpressionValues vfxValues, VisualEffect vfxComponent) { if (state.playing) { float currentRate = vfxValues.GetFloat(rateID); state.spawnCount += currentRate * state.deltaTime; } }
public sealed override void OnStop(VFXSpawnerState state, VFXExpressionValues vfxValues, VisualEffect vfxComponent) { } }
