ParticleSystem.TextureSheetAnimationModule.frameOverTimeMultiplier

説明

The frame over time mutiplier.

Changing this property is more efficient than accessing the entire curve, if you only want to change the overall frame over time multiplier.

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;
    }
}
