public static function MoveTowards(current: Vector3, target: Vector3, maxDistanceDelta: float): Vector3;
public static Vector3 MoveTowards(Vector3 current, Vector3 target, float maxDistanceDelta);
public static def MoveTowards(current as Vector3, target as Vector3, maxDistanceDelta as float) as Vector3

Description

現在の位置 current から target に向けて移動します

この関数によって返された値は直線上の currenttarget の間にある target ごとに移動する target 寄りの位置になります。 targetmaxDistanceDelta よりも近い場合、 返される値は target の位置と同等になります。(すなわち、 target 以上には進みません) target が負の値だと、 target から遠ざかっていきます。

	// The target marker.
	var target: Transform;
	
	// Speed in units per sec.
	var speed: float;
	
	
	function Update () {
		// The step size is equal to speed times frame time.
		var step = speed * Time.deltaTime;
		
		// Move our position a step closer to the target.
		transform.position = Vector3.MoveTowards(transform.position, target.position, step);
	}
