public float startFrameMultiplier ;

描述

起始帧乘数。

如果只想更改整体起始帧乘数,则更改该属性比访问整条曲线更加高效。

using UnityEngine;

[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public float startFrame = 0.0f;

void Start() { ps = GetComponent<ParticleSystem>();

var main = ps.main; main.startLifetimeMultiplier = 2.0f;

var tex = ps.textureSheetAnimation; tex.enabled = true; tex.numTilesX = 4; tex.numTilesY = 2; }

void Update() { var tex = ps.textureSheetAnimation; tex.startFrameMultiplier = startFrame; }

void OnGUI() { startFrame = GUI.HorizontalSlider(new Rect(25, 25, 100, 30), startFrame, 0.0f, 7.0f); } }
