UMG or Touch Interface on mobile?

Development Programming & Scripting UI

Hi, I’m trying to port my project to mobile.

I’ve designed a UI, but now since I’m using an analog stick it seems I can only use Touch Interface, I can’t find any joystick function in UMG.
If I use Touch Interface, the Joystick won’t scale to different screen size and ratio like UMG does.

Anyone has a tip or a tutorial to link on how to implement a Joystick in UMG or to scale Touch Interface?

Seems like the best solution is obviously to use UMG due to the anchoring system, but then again how do we anchor and scale a Joystick from a Touch Interface?

Can import a Touch Interface in a UMG?

I see an Event Tick function, so if there’s a way to GET TOUCH COORD, I could have it listen and translate the results into 2 Floats.
Is there a node that “GET TOUCH COORD”?

I think that’s it!

Now it can only work if it’s possible to get the “CURRENT SCREEN RATIO” along with “TOUCHED BUTTON COORDINATES”.

Anyone knows if there are such nodes?

I think I might just end up manually making Touch Interface profiles for each ratio*screenSize.

Hi there!

I’m facing the same issue now, need to use the Mobile Touch Interface, but need it to be scalable, did you find any smooth solution for that?
