Mathf.MoveTowardsAngle

説明

MoveTowards と同じです。ただし、360 度の回転の場合は、正しく補間されるよう注意してください。

Variables current and target are assumed to be in degrees. For optimization reasons, negative values of maxDelta are not supported and may cause oscillation. To push current away from a target angle, add 180 to that angle instead.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public float target = 270.0F;
    public float speed = 45.0F;
    void Update() {
        float angle = Mathf.MoveTowardsAngle(transform.eulerAngles.y, target, speed * Time.deltaTime);
        transform.eulerAngles = new Vector3(0, angle, 0);
    }
}
