Unreal-Engine-Simple-Component-Picker

A component picker that is simpler than the built-in FComponentReference. Full disclosure: This code appears to build, run, and serialize without problems on my machine, but I have not tested it in a full, packaged build.

To use the component picker, add the source and header files in this repository to your project, then add the following lines to your game's module's StartupModule function:

FPropertyEditorModule& rPropertyModule = FModuleManager::LoadModuleChecked<FPropertyEditorModule>( "PropertyEditor" );

rPropertyModule.RegisterCustomPropertyTypeLayout(
    "ComponentPicker",
    FOnGetPropertyTypeCustomizationInstance::CreateStatic( &FComponentPickerCustomization::MakeInstance ) );

Then you can add it as a property to your classes like this:

UPROPERTY( EditInstanceOnly )
FComponentPicker m_oComponentPicker;

It supports the following meta tags (which function the same as they do on FComponentReference): AllowAnyActor, AllowedClasses, and DisallowedClasses. For example:

UPROPERTY( EditInstanceOnly, meta = ( AllowAnyActor, AllowedClasses = "PrimitiveComponent", DisallowedClasses = "SkeletalMeshComponent,BrushComponent"" ) )
FComponentPicker m_oComponentPicker;
