You can then reference this object easily getting the property value: .call_function() is more advanced, as it allows for return values and python args: You can easily bind events (as seen before) with the bind_event function. i tried it in ue5 and ue4, in ue4 someone recomended to create a blank c++ file, well i created it, the engine said i have to recompile the project. Is there any easy way in Windows to work out exactly why a DLL fails to load? It is separated from FEditorFileUtils to ensure new easier to use methods can be created without breaking FEditorFileUtils backwards compatibility Remember that for components, the self.uobject field point to the component itself, not the actor.

Remember to add a mesh component to it (like a sphere) and set its collision behaviour as 'OverlapAll'. (The key is the UObject pointer, the value is the ue_PyUObject pointer). It might be possible to create an updated version (ue5). Great content! A constant plugin install error is present in bridge when trying to install for UE 4.25.
