Mathf.Clamp

Description

Clamps a value between a minimum float and maximum float value.

// Set the position of the transform to be that of the time
// but never less than 1 or more than 3

function Update () {
    transform.position = Vector3(Mathf.Clamp(Time.time, 1.0, 3.0), 0, 0);
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Update() {
        transform.position = new Vector3(Mathf.Clamp(Time.time, 1.0F, 3.0F), 0, 0);
    }
}

Description

Clamps value between min and max and returns value.

// Clamps the value 10 to be between 1 and 3.
// prints 3 to the console

print(Mathf.Clamp(10, 1, 3));

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    // Use this for initialization
    void Start()
    {
        // Clamps the value 10 to be between 1 and 3.
        // prints 3 to the console

        Debug.Log(Mathf.Clamp(10, 1, 3));
    }
