测试这个文档描述的UE模板类https://github.com/Tencent/puerts/blob/e83b036ce3b8c49f723e988ae972b136887b4a76/doc/unreal/zhcn/template_binding.md

TSharedPtr
声明：UsingTSharedPtr(FVector);
注册：RegisterTSharedPtr(FVector);

自己写了一个测试类，也会报错，但是 https://github.com/chexiongsheng/puerts_unreal_demo.git 这个项目的puerts插件不会报错
对比了一下修改的地方太多了，不知道是哪儿的问题

通过注释发现是RegisterTSharedPtr(FVector);这行的问题

报如下错误：

添加如下代码
声明：UsingTSharedPtr(FVector);
注册：RegisterTSharedPtr(FVector);

The text was updated successfully, but these errors were encountered:

chexiongsheng · 2024-04-10T07:01:30Z

试试前面加上UsingUStruct(FVector);

9000miles · 2024-04-10T08:56:11Z

试试前面加上UsingUStruct(FVector);

添加了，代码示例如下：

#include "CoreMinimal.h"
#include "Binding.hpp"
#include "UEDataBinding.hpp"

UsingUStruct(FVector);
UsingTSharedPtr(FVector);

struct AutoRegisterForTest
{
	AutoRegisterForTest()
	{
		RegisterTSharedPtr(FVector);
	}
};

AutoRegisterForTest __AutoRegisterForTest__;

依然报错：
正如前所述：同样的代码放在 https://github.com/chexiongsheng/puerts_unreal_demo.git 这个项目则不会报错

是不是版本问题？puerts_unreal_demo.git的puerts同步到master。找不到GetArgsLen我记得是某个版本的问题，你试试更新到master

我可能没说清楚，不是在puerts_unreal_demo.git这个库出的问题，而是Unreal_v1.0.6p1这个版本的插件出了问题，上面的报错都是在Unreal_v1.0.6p1发现的。

另外

demo项目已经更新到master最新提交，但是我发现demo项目的插件并不是Unreal_v1.0.6p1这个版本，在demo项目是OK的，并不会报上面的错误

建议

你可以直接在Unreal_v1.0.6p1插件里添加如下代码测试

#include "CoreMinimal.h"
#include "Binding.hpp"
#include "UEDataBinding.hpp"

UsingUStruct(FVector);
UsingTSharedPtr(FVector);

struct AutoRegisterForTest
{
	AutoRegisterForTest()
	{
		RegisterTSharedPtr(FVector);
	}
};

AutoRegisterForTest __AutoRegisterForTest__;

chexiongsheng · 2024-04-11T04:35:40Z

我说的某个版本，就是v1.0.6p1版本

chexiongsheng · 2024-04-11T06:06:59Z

我说的就是这个意思，
