So, I understand that the only way to have a player on mobile is through a Mobile Placeable Pawn that takes all the input. So how, in unrealscript, do you give the control to that mobile placeable pawn?
Having a placeable pawn is most certainly not the only way to have a player in mobile games. You should be able to have first person just like Epic Citadel or have a 3rd person view with a player mesh if you want. It just isn't set up by default I don't think. There is nothing specifically prohibiting it, though.
