How to attach a VR Pawn to an Actor

Hi,

I have to attach a VR Pawn to a movable platform. I tried the “attach to” node inside the platform actor without any succes. (I’m an artist not a programmer. sry for that easy question)

This can be tricky because the VR Pawn doesn’t have a “body” nor a collision capsule and does not have a character movement component either. You can try something like this:

add a collision volume to your pawn (e.g. attached to the root or to the VR camera)
enable the volume generate overlap events
detect when the Pawn gets on the platform by detecting the Begin Overlap Event with a collision volume on the platform actor → set a boolean variable to register the fact the pawn is now on the platform (e.g. IsOnPlatform). This can be trick if your Pawn only has a teleport type of movement.
on Event Tick, check the boolean variable IsOnPlatform and, if true, move the pawn by the same movement the platform had over the last tick
if the Pawn gets off the platform (again, tricky if you only have tele transport type of movement), then set the IsOnPlatform to false
