설명

Explicitly select which row of the texture sheet is used, when ParticleSystem.TextureSheetAnimationModule.useRandomRow is set to false.

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public bool useRandomRow = true;

        main.startLifetimeMultiplier = 2.0f;

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

        var tex = ps.textureSheetAnimation;
        tex.useRandomRow = useRandomRow;
        tex.rowIndex = row;
