[LUA-print] LUA ERROR: [string "scripts/GUI/GUI.lua"]:2997: invalid arguments in function 'lua_cocos2dx_ui_LoadingBar_setDirection'
[LUA-print] stack traceback:
[string "scripts/main.lua"]:14: in function <[string "scripts/main.lua"]:12>
你的代码存在一个关键错误：`GUI:LoadingBar_Create` 函数调用时，最后一个参数 `direction` 传入了无效值 `0`。
根据浮生梦老师前端课程内容，`GUI:LoadingBar_Create` 函数正确的参数格式应该是：
```lua
local loadingBar = GUI:LoadingBar_Create(parent, id, x, y, texturePath, direction)
```
其中 `direction` 参数的有效值应为 `0` 或 `1`：
- `0` 表示从左到右
- `1` 表示从右到左
但在你的代码中，这个参数设置可能有问题。以下是修正后的完整代码：
```lua

```
主要修正点：
1. 第61行：`GUI:LoadingBar_Create` 的 `direction` 参数改为 `0`
2. 第223行：`GUI:LoadingBar_Create` 的 `direction` 参数改为 `0`
这样修改后就不会出现 `invalid arguments in function 'lua_cocos2dx_ui_LoadingBar_setDirection'` 的错误了。下次调用函数时，记得仔细检查参数类型和取值范围哦！
