ParticleSystem.TextureSheetAnimationModule.fps

描述

控制动画的播放速度。

当 ParticleSystem.TextureSheetAnimationModule.timeMode 设置为 FPS 时，系统使用此属性。

using UnityEngine;

[RequireComponent(typeof(ParticleSystem))]
public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public float fps = 30.0f;

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

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

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

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

    void OnGUI()
    {
        GUI.Label(new Rect(25, 20, 100, 30), "FPS");

        fps = GUI.HorizontalSlider(new Rect(125, 25, 100, 30), fps, 1.0f, 60.0f);
    }
}
