Add a pressable button

By the end of this you will have a physical button the player can press with a fingertip in VR and click on desktop.

Steps

1. Create an actor with a mesh and a collision component. Tag the collision component, for example Press.
2. Add a BPC_Interaction_Overlap component and set Component Tag Of Collision to that tag.
3. Set Allowed Identifiers to the fingertip ability identifier if only a fingertip should press it, or leave it empty to accept any.
4. Bind to Overlap Started and Release.
5. Add a BPC_Interaction_Select as well so the same button works on desktop.

Notes

For a button that physically depresses, use BPC_Interaction_Overlap_Drag with a BPC_State_Drag component instead, and set Component Tag Of Drag Comp to point at it.
