ParticleSystem.MainModule.gravityModifierMultiplier

Description

Change the gravity multiplier.

Changing this property is more efficient than accessing the entire curve (ParticleSystem.MainModule.gravityModifier), if you only want to change the overall gravity multiplier.

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(ParticleSystem))]
public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public float hSliderValue = 0.0F;

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

    void Update()
    {
        var main = ps.main;
        main.gravityModifierMultiplier = hSliderValue;
    }

    void OnGUI()
    {
        hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, -5.0F, 5.0F);
    }
}
