c# - 2048 的游戏开发者是如何让他们的棋子顺利移动的？看下面的细节

Question

我制作了 2048 游戏的完整副本，但我通过传送移动了方 block (没有像在原始游戏中那样平滑地移动方 block )

我使用以下代码来平滑移动瓷砖。

//GameManager script
 void MoveRight () {
     //some code ..
     AnimateTileMovement (newPosition); // newposition is the position to whihc the tiles is going to move
     //some code which i need to execute (ONLY AFTER MY COMPLETE MOVEMENT OF TILE)
     // BUT AS SOON AS TileMovement return its first null this code execute which is creating a lot of problem , what should i do ?
     //to stop execution these code until the tiles have moved towards its desired newPosition
 }

 //TilesMovement Script 

 public void AnimationTileMovement(Vector3 newPosition) {
     StartCoroutine ("TileMovement", newPosition);

 }

 IEnumerator TileMovement(Vector3 newPosition) {
     while (transform.position != newPosition) {
         transform.position = Vector3.MoveTowards (transform.position, newPosition, speedTile * Time.deltaTime);
         yield return null;

     }


 }

我花了好几天时间来实现这一点，但我无法停止执行 StartCoroutine ("TileMovement", newPosition) 下面的代码，因为代码在第一次移动时就被执行了当 IEnumerator TileMovement(Vector3 newPosition) 首先返回 null 时？

我已阅读这篇文章并尝试过但无法这样做请建议我该怎么做 Coroutines unity ask

Answer 1

你的问题就这么简单，

ONLY AFTER MY COMPLETE MOVEMENT OF TILE...

和

i have been spending days to achieve this but i am not able to do how to stop executing the code ...

如果你想启动协程，但继续....

Debug.Log("we're at A");
StartCoroutine("ShowExplosions");
Debug.Log("we're at B");

这将打印“A”，并开始爆炸动画，但它们会立即继续并打印“B”。 (它将打印“A”然后立即打印“B”，爆炸将在打印“B”的同时开始运行，然后继续运行。)

然而....

如果你想启动协程，然后等待...

Debug.Log("we're at A");
yield return StartCoroutine("ShowExplosions");
Debug.Log("we're at B");

这将打印“A”。然后它将开始爆炸并等待:它什么都不做直到爆炸结束。 只有这样它才会打印“B”。

这是 Unity 中常见的基本错误。

不要忘记“ yield 返回”!

注意!

当然是这段代码

Debug.Log("we're at A");
yield return StartCoroutine("ShowExplosions");
Debug.Log("we're at B");

必须自己在协程中。所以你会有类似...

public IEnumerator AnimationTileMovement(...)
   {
   Debug.Log("we're at A");
   .. your pre code
   yield return StartCoroutine("ShowExplosions");
   Debug.Log("we're at B");
   .. your post code
   }

在 MoveRight 中你会拥有

public void MoveRight(...)
   {
   StartCoroutine( AnimateTileMovement(newPosition) );

有道理吗？
