为纹理帧动画定义随机初始帧。
另请参阅:MinMaxCurve。
using UnityEngine;
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.startFrame = startFrame;
}
void OnGUI()
{
startFrame = GUI.HorizontalSlider(new Rect(25, 25, 100, 30), startFrame, 0.0f, 7.0f);
}
}
