ParticleSystem.ExternalForcesModule.multiplier

Description 描述

Multiplies the magnitude of applied external forces.

This method is more efficient than accessing the whole curve, if you only want to change the overall force multiplier.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public bool moduleEnabled = true;
    public float hSliderValue = 10.0f;

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

        GameObject wind = new GameObject("Wind", typeof(WindZone));
        wind.transform.parent = ps.transform;
        wind.transform.localPosition = new Vector3(-4.0f, 0.0f, 0.0f);
        wind.GetComponent<WindZone>().mode = WindZoneMode.Spherical;
    }

    void Update()
    {
        var externalForces = ps.externalForces;
        externalForces.enabled = moduleEnabled;
        externalForces.multiplier = hSliderValue;
    }

    void OnGUI()
    {
        moduleEnabled = GUI.Toggle(new Rect(25, 45, 100, 30), moduleEnabled, "Enabled");
        hSliderValue = GUI.HorizontalSlider(new Rect(25, 85, 100, 30), hSliderValue, 0.0f, 100.0f);
    }
