ParticleSystem.TextureSheetAnimationModule.frameOverTimeMultiplier

描述

随时间变化的帧乘数。

如果只想更改整体随时间变化的帧乘数，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;

    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;
        tex.frameOverTimeMultiplier = 2.0f;
    }
}
