# ringBufferLoopRange

> When _ringBufferMode is set to loop, this value defines the proportion of the particle life that loops.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public Vector2 ringBufferLoopRange { get; set; }
```

### Remarks

This enables you to use other particle properties that are applied over the particle lifetimes, such as SizeOverLifetime. When the system must replace a particle, it plays the particle from its current age to its full lifetime. Then, removes it.

### Examples

```csharp
using UnityEngine;
using System.Collections;

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

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

    void Update()
    {
        var main = ps.main;
        main.ringBufferLoopRange = new Vector2(0.1f, 0.6f);
    }
}
```
