It seems that is impossible to make a choosing a different character, so my question is is there any way to choose another world in UI but if you can enough game currencies?
Right now, with Buildbox 3D being in Beta, purchasing or choosing another character is not implemented, but I am pretty sure it will be added in the release version. Maybe a Moderator can better answer this for you, I don't want to mislead you.
You can change character by code in a world. no need to new world. i made in my game. i will share later how to make it. now i have finish game first
