Web Remote Control not responding in Game (only in editor)

Development Programming & Scripting Blueprint
1

Hello,

I followed this tutorial: https://docs.unrealengine.com/en-US/…art/index.html

Everything works fine in the editor and I was also able to apply this to meshs position - so i can change its location with the the remote control.

But when I run this in play mode, the remote control does not update anything, it only updates in the editor as soon as I stop the game preview.

Any Ideas?

Thanks
Felix

You are probably using the editor UWorld path. In editor, there is always a UWorld editor. When you enter play mode, this editor UWorld is copied in a temporary game UWorld that will be destroyed once you exit play mode. the game UWorld has a different path than the Editor world.

For example, to access a light in editor I use this path :


    "objectPath" : "/Game/VprodProject/Maps/Main.Main:PersistentLevel.Sunlight.LightComponent0"

and to access the same in Play In Editor mode I use


    "objectPath" : "/Game/VprodProject/Maps/UEDPIE_0_Main.Main:PersistentLevel.Sunlight.LightComponent0"

note : in code you can get the current editor UWorld or game UWorld with either


UWorld* world = UEditorLevelLibrary::GetEditorWorld();

or


UWorld* world = UEditorLevelLibrary::GetGameWorld();

That’s very interesting.
What happens to me is that I get the changes in editor if I click on something but not instantly. Maybe there’s a “refresh scene” trigger or something I’m missing.

This does work for me, I can get the Remote Control API working in Editor and in PIE Mode. But I can’t send any requests when I’m in Standalone Mode or when I package the game. Is there a different suffix for standalone or does the Remote Control API only work with the Editor?

Old thread, but writing anyway, if someone else is looking for the answer.

The address in a packaged game (in my experience) is the same as in the editor (not as in PIE), but,
you have to enable the Remote Control Web server with this command line flag when you launch the game. (I only use the first one):

-RCWebControlEnable -RCWebInterfaceEnable
