Unity 物体移动方式

Unity 物体移动方式

直接移动

	
obj.transform.position = new Vector3(0, 0, 0);


	
 


	
obj.transform.position += Vector3.forward * moveSpeed * Time.deltaTime;

	
var destination = new Vector3(0, 0, 0);


	
 


	
obj.transform.position = obj.transform.position + (destination - obj.transform.position).normalized * speed;

Vector3

	
// MoveTowards


	
obj.transform.position = Vector3.MoveTowards(from, to, duration);


	
// Lerp数学插值，


	
obj.transform.position = Vector3.Lerp(from, to, duration);


	
 

transform.translate

使用协程 + AnimationCurve

实现自定义运动轨迹

	
public AnimationCurve curve;


	
 


	
IEnumerator move(GameObject obj, Vector3 from, Vector3 to, float perTime)


	
        {


	
            float percent = 0;


	
           


	
            Debug.LogFormat("UIForwardItems.move obj name:{0}, from:{1}, to:{2}", obj.name, from, to);


	
            while (percent < 1)


	
            {


	
                percent += Time.deltaTime / perTime;


	
               


	
                obj.transform.position = Vector3.Lerp(from, to, curve.Evaluate(percent));


	
                // 另一种Lerp


	
                //obj.transform.position = Vector3.LerpUnclamped(from, to, curve.Evaluate(percent));


	
                yield return null;


	
            }


	
 


	
           


	
        }

UITween

	
public void move(GameObject obj, Vector3 from, Vector3 to, bool useWorld, float duration, float delay, EventDelegate.Callback onFinish)


	
{


	
    TweenPosition tween = ((GameObject)obj).GetComponent<TweenPosition>();


	
    


	
    tween.from = from;


	
    tween.to = to;


	
    tween.useWorldSpace = useWorld;


	
    tween.duration = duration;


	
    tween.delay = delay;


	
    tween.style = duration < 0 ? UITweener.Style.PingPong : UITweener.Style.Once;


	
    tween.ResetToBeginning();


	
    tween.SetOnFinished(onFinish);


	
    tween.PlayForward();


	
}

使用DOTween插件

	
//花费0.5秒, 移动到111


	
transform.doMove(Vector3.one, 0.5f);

注：

如果要移动拥有LayoutGroup组件下的子物体，

LayoutGroup排版计算是在下一帧才进行，需要强制进行刷新，实现布局实时计算，具体代码如下：

LayoutRebuilder.ForceRebuildLayoutImmediate(this.GetComponent<RectTransform>());
