Unity如何利用协程完成按顺序操作？
例如有三个按钮ABC，功能分别是Debug打印"This is A"/“This is B"/"This is C"。现在需要用户按顺序点击ABC，顺序正确时实现相应按键功能，否则另外打印"Wrong"，然后要求用户继续按顺序点击按钮。
例：用户先点击A，控制台打印”This is A“；然后点击C，打印”Wrong“；再点击A，打印”Wrong“；点击B，打印"This is B";最后点击C打印"This is C",完成。

思路都是差不多的，改改就行了

用不着协程
public class NewBehaviourScript : MonoBehaviour

public void ButtonClick(int x)
{
if(x-1==temp)
{

temp++;
}else
{
Debug.Log("顺序点错了");
}
if (temp == 3)
{
Debug.Log("完成");
temp=0;
}
}
}
三个按钮A B C依次添加带参数的监听参数分别是1 2 3.
