Mathf.Repeat

Description

Loops the value t, so that it is never larger than length and never smaller than 0.

This is similar to the modulo operator but it works with floating point numbers. For example, using 3.0 for t and 2.5 for length, the result would be 0.5. With t = 5 and length = 2.5, the result would be 0.0. Note, however, that the behaviour is not defined for negative numbers as it is for the modulo operator.

In the example below the value of time is restricted between 0.0 and just under 3.0. This is then used to keep the x position in this range.

#pragma strict
public class Example extends MonoBehaviour {
	function Update() {
		// Set the x position to loop between 0 and 3
		transform.position = new Vector3(Mathf.Repeat(Time.time, 3), transform.position.y, transform.position.z);
	}
}

using UnityEngine;

public class Example : MonoBehaviour
{
    void Update()
    {
        // Set the x position to loop between 0 and 3
        transform.position = new Vector3(Mathf.Repeat(Time.time, 3), transform.position.y, transform.position.z);
    }
}
