ParticleSystem.MainModule.simulationSpace

描述

这选择模拟粒子的空间。它可以是世界空间或局部空间。

使用以下示例在局部空间和世界空间模拟之间切换

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(ParticleSystem))]
public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public bool useLocal = true;

    void Start()
    {
        ps = GetComponent<ParticleSystem>();
        var main = ps.main;
        useLocal = main.simulationSpace == ParticleSystemSimulationSpace.Local;
    }

    void Update()
    {
        var main = ps.main;
        main.simulationSpace = useLocal ? ParticleSystemSimulationSpace.Local : ParticleSystemSimulationSpace.World;
    }

    void OnGUI()
    {
        useLocal = GUI.Toggle(new Rect(10, 60, 200, 30), useLocal, "Use Local Simulation Space");
    }
}

使用以下示例相对于独立的游戏对象模拟粒子

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ParticleSystemScript : MonoBehaviour
{
    private ParticleSystem ps;
    public Transform relativeTo;

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

        var main = ps.main;
        main.simulationSpace = ParticleSystemSimulationSpace.Custom;
        main.customSimulationSpace = relativeTo;
    }

    void Update()
    {
    }
}
