Vector3.Angle

Parameters

Description

2点間（ from と to ）の角度を返します

角度は常に2つのベクトル間の 鋭角 を返します。(すなわち、必ず角度は180度未満)

	// prints "close" if the z-axis of this transform looks
	// almost towards the target

	var target : Transform;
	function Update () {
		var targetDir = target.position - transform.position;
		var forward = transform.forward;
		var angle = Vector3.Angle(targetDir, forward);
		if (angle < 5.0)
			print("close");
	}
