指定该FRigUnit里的属性要用自定义的控件来编辑。
|
|||
|
|
|
|||
|
|
CustomWidget的值是在一些选项中选择的，这些自定义控件是已经在引擎中实现的。
|
|||
|
|
|
|||
|
|
可用的列表为：BoneName，ControlName，SpaceName/NullName，CurveName，ElementName，ConnectorName，DrawingName，ShapeName，AnimationChannelName，MetadataName，MetadataTagName。
|
|||
|
|
|
|||
|
|
测试代码里就只用BoneName作为测试展示：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
USTRUCT(meta = (DisplayName = "MyRigCustomWidget"))
|
|||
|
|
struct INSIDER_API FRigUnit_MyRigCustomWidget : public FRigUnit
|
|||
|
|
{
|
|||
|
|
GENERATED_BODY()
|
|||
|
|
|
|||
|
|
RIGVM_METHOD()
|
|||
|
|
virtual void Execute() override;
|
|||
|
|
public:
|
|||
|
|
UPROPERTY(meta = (Input))
|
|||
|
|
FString MyString;
|
|||
|
|
|
|||
|
|
UPROPERTY(meta = (Input, CustomWidget = "BoneName"))
|
|||
|
|
FString MyString_Custom;
|
|||
|
|
|
|||
|
|
UPROPERTY(meta = (Output))
|
|||
|
|
float MyFloat_Output = 123.f;
|
|||
|
|
};
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 测试效果：
|
|||
|
|
|
|||
|
|
可见MyString_Custom的Pin类型变成可选BoneName的列表。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 原理：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
TSharedPtr<SGraphPin> FControlRigGraphPanelPinFactory::CreatePin_Internal(UEdGraphPin* InPin) const
|
|||
|
|
{
|
|||
|
|
if (CustomWidgetName == TEXT("BoneName"))
|
|||
|
|
{
|
|||
|
|
return SNew(SRigVMGraphPinNameList, InPin)
|
|||
|
|
.ModelPin(ModelPin)
|
|||
|
|
.OnGetNameFromSelection_UObject(RigGraph, &UControlRigGraph::GetSelectedElementsNameList)
|
|||
|
|
.OnGetNameListContent_UObject(RigGraph, &UControlRigGraph::GetBoneNameList)
|
|||
|
|
.OnGetSelectedClicked_UObject(RigGraph, &UControlRigGraph::HandleGetSelectedClicked)
|
|||
|
|
.OnBrowseClicked_UObject(RigGraph, &UControlRigGraph::HandleBrowseClicked);
|
|||
|
|
}
|
|||
|
|
//等等其他
|
|||
|
|
}
|
|||
|
|
```
