unity array get next prev index

 

Clamp를 사용하면 원하는 값을 딱 얻을 수 있네

    설명

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

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);

    }

}

public static int Clamp (int value, int min, int max);

설명

Clamps value between min and max and returns value.

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

// prints 3 to the console

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