ParticleSystem.TrailModule.dieWithParticles

描述

指定轨迹在其拥有的粒子湮灭时是否立即消失。如果是 false，每个轨迹会持续存在到其所有点都自然过期（基于其生命周期）。

        main.startColor = new ParticleSystem.MinMaxGradient(Color.red, Color.yellow);
        main.startSizeMultiplier = 0.1f;
        main.startLifetimeMultiplier = 1.0f;

        var trails = ps.trails;
        trails.enabled = true;

        var psr = GetComponent<ParticleSystemRenderer>();

    }

    void Update()
