スクリプトによるユニティプレーヤーのフリーズ

Question

私のユニティプレーヤーはしばらくしてもフリーズし続けていますが、実際にそれを引き起こしているスクリプトが何かを知っています。私が凍結を開始したときに私が編集したスクリプトは1つしかないからです。でも、なぜ凍っているのか分かりません！私は凍結がSpawnPickups方法および/またはそれがResetGame方法でピックアップを破壊する部分とは何かを持っていることを小さなsuspectionを持っています

： はここでそれを引き起こしているスクリプトです。

Answer 1

あなたのメソッドSpawnPickupsがこれをしています。 このコルーチンを呼び出すとenableがtrueで実行がfalseの場合、 "yield"命令に達することはありません。したがって、while（有効）は実際には真です（真）

コルーチンはスレッドではなく、メインスレッドと、このようなコルーチンをブロックすると、あなたはゲームをブロックしています。

public IEnumerator SpawnPickups() { 
    while(enabled) { 
     Debug.Log("SpawnPickups running..."); 
     if(running) { 
      if(pickupsParent.childCount < maxPickups) { 
       int type = Random.Range(0, pickupTypes.Length); 
       float X = Random.Range(-7f, 7f); 
       float Y = Random.Range(-3f, 3f); 
       Vector3 spawnPos = new Vector3(X, Y, 0); 
       /*GameObject newPickup = */Instantiate(pickupTypes[type], spawnPos, Quaternion.Euler(0, 0, 0), pickupsParent); 
       Debug.Log("SpawnPickups instantiated new pickup..."); 
       yield return new WaitForSeconds(spawnPickupThreshold); 
      } 
      //Here you need some yield in case running is true but you reached maxPickups (this one is not necessary if you put the next one) 
     } 
     //Here you need some yield in case running is false 
     //yield return null; //this should be enough to prevent your game from freezing 
    } 
}
