Development Programming & Scripting Blueprint

This is for a vr game in Unreal Engine 5.4.3 btw:
I am trying to make a spherical actor reset to the location it started from when i click a physical button. Right now i have a pawn in the shape of a cube with an “actor begin overlap” event so that i can put my hand starting the command, but it wont seem to make the ball move back no matter what I do.

BP_PButton is the blueprint for the button/pawn that i am trying to interact with
BP_MoveableActor is the ball i am trying to move back when i interact with the button

I have tried anything I can think of for hours, and I still cant get anything to work. PLEASE help me

Hi,
Can you make sure that the button’s Event Actor Begin Overlap is firing? (Put a Print String node)
If it is not, the Actor Begin Overlap might be trying to use the root component of your pawn. Can you replace the DefaultSceneRoot with your Box collider and try again?

Thanks for your reply
I put the print string node and as you guessed it didnt print anything to the log (make sure i did this right please im pretty new to blueprints)

incase it didnt notify you from my message ^

Just drag the “Box” component over your Default Scene Root and try again:

(or link it with the node you have below which is component specific)

If that still doesn’t fire you will have to check your collision settings for both the pawn and the actor.

Also try putting a print string on cast failed, if the cast isn’t working maybe try get actor of class

Update:
I added a print string node after the cast on the cast failed link and i think i understand whats happening but I dont know how to fix it:
When i touch the pawn with my vr hand, nothing happens, but when i hit it with another actor, it fires the actor begin overlap event and prints “hello”. after that, however, it also prints from the second print string in the cast failed link, “it failed”. So there are two problems now

  1. the pawn doesnt notice my hand as an actor trying to interact with it,
  2. the pawn is failing when it tries to cast to the moveable actor

    output log after i touched the pawn with another actor ^ (when i touched it with my hand it printed nothing) and the current blueprint for the pawn
    any idea how to solve either or both of these?
    thanks

As I can see it you only have one problem - the hand actor is not interacting with your object.
The casting thing is understandable since we are poking it with other objects which are not supposed to work anyway.

Unfortunately I don’t have that much experience with VR. However, I found a thread with a similar problem: How to use box collision with VR hands on UE5?

Hope it helps…
