问题：属性(Property)和访问器(Accessor)
如果在当前属性中直接添加自定义get和set访问器，在Unity引擎中访问/修改此属性时游戏会闪退。

public int TestProperty {
get { return TestProperty;}
set {

解决方案
- 直接使用默认访问器

- 创建一个新属性专门用于访问

问题：Start函数中使用不当loop循环
如果在start函数中使用while循环处理资源加载进度条，Unity引擎会在importing asset弹窗中卡死

asyncHandle.Completed += EnterGame;
StartCoroutine(GameLoadingCoroutine(asyncHandle));
}

while (!handle.IsDone && handle.PercentComplete < 1f)
loadingBar.SetProgressPercent(handle.PercentComplete);
}
private void EnterGame() {
}
}

解决方案
使用协程(Coroutine)将while操作与Unity生命周期同步

问题：在Awake/Start函数中修改GameObject位置
在Awake/Start函数中GameObject的position component尚未初始化完成，此时修改位置将不会起作用

| private void Start() {
var newPos = transform.localPosition;
newPos.y += 100;
transform.localPosition = newPos;
}

解决方案
- 在Start函数中等待一帧后再修改位置，此时GameObject的position component可使用

var newPos = transform.localPosition;
newPos.y += 100;

}

- 在Awake/Start函数之后的函数进行修改位置操作
问题：使用dotween移动layout group中的游戏对象会影响其他游戏对象
举例：一个老虎机有5个转轴Reel[] reels，移动reels[2]会将reels[0]和reels[1]的position清零
