标识FRigUnit在蓝图右键菜单项的名字后缀。
|
|||
|
|
|
|||
|
|
## 测试代码：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
USTRUCT(meta = (DisplayName = "MyRigSuffix", MenuDescSuffix = "(MyVector)"))
|
|||
|
|
struct INSIDER_API FRigUnit_MyRigSuffix: public FRigUnit
|
|||
|
|
{
|
|||
|
|
GENERATED_BODY()
|
|||
|
|
|
|||
|
|
RIGVM_METHOD()
|
|||
|
|
virtual void Execute() override;
|
|||
|
|
public:
|
|||
|
|
UPROPERTY(meta = (Input))
|
|||
|
|
float MyFloat_Input = 123.f;
|
|||
|
|
|
|||
|
|
UPROPERTY(meta = (Output))
|
|||
|
|
float MyFloat_Output = 123.f;
|
|||
|
|
};
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 测试效果：
|
|||
|
|
|
|||
|
|
可见出现了"(MyVector)"的后缀。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 原理：
|
|||
|
|
|
|||
|
|
得到该数据，然后添加到DisplayName后面。
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
FString CategoryMetadata, DisplayNameMetadata, MenuDescSuffixMetadata;
|
|||
|
|
Struct->GetStringMetaDataHierarchical(FRigVMStruct::CategoryMetaName, &CategoryMetadata);
|
|||
|
|
Struct->GetStringMetaDataHierarchical(FRigVMStruct::DisplayNameMetaName, &DisplayNameMetadata);
|
|||
|
|
Struct->GetStringMetaDataHierarchical(FRigVMStruct::MenuDescSuffixMetaName, &MenuDescSuffixMetadata);
|
|||
|
|
|
|||
|
|
if(DisplayNameMetadata.IsEmpty())
|
|||
|
|
{
|
|||
|
|
DisplayNameMetadata = Struct->GetDisplayNameText().ToString();
|
|||
|
|
}
|
|||
|
|
if (!MenuDescSuffixMetadata.IsEmpty())
|
|||
|
|
{
|
|||
|
|
MenuDescSuffixMetadata = TEXT(" ") + MenuDescSuffixMetadata;
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
FText MenuDesc = FText::FromString(DisplayNameMetadata + MenuDescSuffixMetadata);
|
|||
|
|
```
