Mathf.Clamp01

설명

Clamps value between 0 and 1 and returns value.

If the value is negative then zero is returned. If value is greater than one then one is returned.

using UnityEngine;

public class Example : MonoBehaviour
{
    // Set the position of the transform to be that of the time
    // but never less than 0 or more than 1

    void Update()
    {
        transform.position = new Vector3(Mathf.Clamp01(Time.time), 0, 0);
    }
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

// Print a random number every second.  This number is chosen over a
// range from startValue to endValue.  The random number is clamped
// to between zero and one by Clamp01().

public class ExampleScript : MonoBehaviour
{
    public float startValue = -0.5f;
    public float endValue = 1.5f;

    private float timeCount = 0.0f;

    void FixedUpdate()
    {
        timeCount += Time.deltaTime;

        if (timeCount > 1.0f)
        {
            float result = Random.value;
            result = result * (endValue - startValue);
            result = result + startValue;

            float clampValue = Mathf.Clamp01(result);

            Debug.Log("value: " + result.ToString("F3") + " result: " + clampValue.ToString("F3"));

            timeCount = 0.0f;
        }
    }
}
