【Unity】往復処理

Last updated at Posted at 2020-08-22

using UnityEngine;

// ずっと、往復する
public class Forever_MoveSin : MonoBehaviour
{
	public float speedX = 1; // スピードX:Inspectorで指定
	public float speedY = 0; // スピードY:Inspectorで指定
	public float speedZ = 0; // スピードZ:Inspectorで指定
	public float second = 1; // かかる秒数:Inspectorで指定
	
	float time = 0f;

	private void FixedUpdate()  // ずっと、往復する
	{
		time += Time.deltaTime;
		float s = Mathf.Sin(time * 3.14f / second); // 移動量を求める
		this.transform.Translate(speedX * s / 50, speedY * s / 50, speedZ * s / 50); 
	}
}

secondの値を変更すると、その値の秒数間でアタッチされたゲームオブジェクトが往復する。

下記のGifは
インスペクターから
second = 6
に値を変更した例

つまり、6秒間で往復を行う
