Hello,
I’m working on a game where a character (Sophie) falls through a rift or portal device and comes out of a second one the user has placed with his/her finger. I’m trying to keep her velocity and/or other physics information. The problem is, when I call the transition.to for her to move from one rift portal to another, all of that physics information is lost. Some times she arrives at the other rift portal and just sits on top. I’ve posted the code below. Does anybody have any ideas?
