C# 如何阻止两个对象相互重叠？

我正在开发一款类似于Flappy Bird和Jetpack Joyride的游戏，我甚至加入了硬币来购买新角色。但是，当一枚硬币产卵时，它会产卵到墙产卵的右侧，这样做是试图阻止硬币在墙后产卵。但是现在，这些墙正在硬币的上面产卵。我怎样才能解决这个问题

生成列的代码：

if (!GameController.instance.gamePaused)
{
   timeSinceLastSpawned += Time.deltaTime;
   if (!GameController.instance.gameOver && timeSinceLastSpawned >= spawnRate)
   {
       timeSinceLastSpawned = 0f;
       float spawnYPosition = Random.Range(columnMin, columnMax);
       columns[currentColumn].transform.position = new Vector2(spawnXPosition, spawnYPosition);
       currentColumn++;
       if (currentColumn >= columnPoolSize)
           currentColumn = 0;
   } //if
} //if

if(!GameController.instance.gamePaused)
{
    if (!GameController.instance.gameOver)
    {
        timeSinceLastSpawned += Time.deltaTime;

        if (timeSinceLastSpawned>=spawnRate)
        {
            int randCoin = Random.Range(0, 99);
            int coinRand = coinRarity[randCoin];
            switch(coinRand)
            {
                case 1:
                    timeSinceLastSpawned = 0f;
                    float goldSpawnYPosition = Random.Range(coinMin, coinMax);
                    goldCoins[goldCurrentColumn].transform.position = new Vector2(spawnXPosition, goldSpawnYPosition);
                    goldCurrentColumn++;
                    if (goldCurrentColumn >= goldPoolSize)
                        goldCurrentColumn = 0;
                    break;
                case 2:
                    timeSinceLastSpawned = 0f;
                    float diamondSpawnYPosition = Random.Range(coinMin, coinMax);
                    diamondCoins[diamondCurrentColumn].transform.position = new Vector2(spawnXPosition, diamondSpawnYPosition);
                    diamondCurrentColumn++;
                    if (diamondCurrentColumn >= diamondPoolSize)
                        diamondCurrentColumn = 0;
                    break;
                case 3:
                    timeSinceLastSpawned = 0f;
                    float rubySpawnYPosition = Random.Range(coinMin, coinMax);
                    rubyCoins[rubyCurrentColumn].transform.position = new Vector2(spawnXPosition, rubySpawnYPosition);
                    rubyCurrentColumn++;
                    if (rubyCurrentColumn >= rubyPoolSize)
                        rubyCurrentColumn = 0;
                    break;
                case 4:
                    timeSinceLastSpawned = 0f;
                    float emeraldSpawnYPosition = Random.Range(coinMin, coinMax);
                    emeraldCoins[emeraldCurrentColumn].transform.position = new Vector2(spawnXPosition, emeraldSpawnYPosition);
                    emeraldCurrentColumn++;
                    if (emeraldCurrentColumn >= emeraldPoolSize)
                        emeraldCurrentColumn = 0;
                    break;
            } //switch
        } //if
    } //if
} //if

   timeSinceLastSpawned += Time.deltaTime;

当一个墙在一枚硬币上生成时，我希望发生的是让它这样硬币被“删除”（在本例中，只是从墙中的位置移动到屏幕外的原始生成点，因为它全部在一个硬币“池”中）

非常感谢您的帮助。

这可以通过使用

碰撞器来完成，或者在您的情况下，可能是
碰撞R2D。
我猜您已经在使用碰撞器来检测玩家是否击中硬币或墙壁，所以只需添加逻辑来检测碰撞对象是柱体还是玩家

void OnTriggerEnter2D(Collider2D col)
{
    if(col.name == "playerObject"){
        //Increase coins?
    }
    this.respawn();
}

这可能是我没有意识到的一个非常明显的修正。但无论如何，谢谢你向我指出这一点me@DodgeCoder如果您想要一个不太明显的解决方案，您还可以通过向子对象添加碰撞器来挑战自己，给它一个特定的层，然后调整物理矩阵，以便只有列层将触发该子对象的
OnTriggerEnter
！（别忘了确保玩家对象不会击中该层！）
