# gravityModifierMultiplier

> Change the gravity multiplier.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public float gravityModifierMultiplier { get; set; }
```

### Remarks

Changing this property is more efficient than accessing the entire curve ([\_gravityModifier](/engine/6000.5/script-reference/unityengine/particlesystem/mainmodule/gravitymodifier.md)), if you only want to change the overall gravity multiplier.

### Examples

```csharp
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);
    }
}
```
