Probably there’s a way to do this already that I don’t know how to do yet, but I wish there were a “layer” logic brick that could be used to move objects from one layer to another, similar to “m” in layer animation. And I wish that that even would be recording in “Record animation.”
Most importantly, though, I would really love it if the devs focused on making the BGE more compatible (less user-hateful?) for use in animation. Half the time I get the feeling that the people who mostly use BGE just to make games don’t realize that “record animation” often has strange effects. There seems a giant wall between the “game makers” and the “animators,” but it shouldn’t be that way. BGE could be incredibly useful to animators for generating realistic physics. But it’s often extremely difficult and confusing to get there, and it’s often quicker to simply animate every single thing by hand.
Sorry for the rant. It’s frustrating.
