I’m new to UE4 and blueprints, so after three days of trying to figure it out by myself, I’m finally asking for help here. This topic might also be relevant to VR, but I think it fits better here.
For a project I’m doing in university, I want to have a widget that is attached to my left hand. The widget is supposed to display images that can be changed by pressing buttons. But here is the thing: I want to use actual “physical” buttons that you literally press in VR. To do so, I’ve followed this tutorial: Unreal Engine - [VR] Interactive Watch Menu - YouTube
It’s working great, I’ve attached it to the hand mesh in the motion controller blueprint (I’m using the VR Template) and destroyed the original one so now it only exists on the left hand. The buttons are working fine, I can press them and testing has shown that they are set up correctly.
A friend also provided me with a widget blueprint that, in theory, is working as I want it to work. I can put images into an array variable, and using the widget buttons I can switch the images by clicking on the buttons.
But since I am making a VR experience, I need the widget to switch the images when I “physically” press the buttons in VR. So my widget blueprint does not actually have buttons, it needs to receive input from the button action event created in the tutorial.
I’ve attached an image that is showing what I want to do. Simply put, the “event button action” should call to the widget blueprint to trigger the logic there.
I’ve tried casting, dispatching, I even tried rebuilding the widget logic in the motion controller blueprint. But the only thing I managed to do was crashing the editor upon hitting the button.
I’ve also been all over the forums and youtube to find solutions, but I only found stuff dealing with widgets you have to click, or click with the “widget interaction” component.
The project is due in 10 days and I’m studying architecture, not game design or anything. So I’m not asking anybody to do my homework. I would just like to have this seemingly simple gameplay element so that the people using my VR experience can look through various floorplans and sections while walking through the project.
Thanks in advance and I really appreciate any help I can get.
