So in this game that I am creating, I want to create a couple different stages, they are all the same, just looks different. I know I can duplicate the entire world, but is there a possible way to change the objects only in the new world? Or a simpler solution rather then having to place all the objects in place again for a good 100+ stages?
unfortunately you will need to replace all the object in each world we still waiting this feature to be implemented in future release.
The implementation of something like this, if it happens, will be after Buildbox 3. This opens up quite a few issues that we are not capable of handling correctly right now. Buildbox 3 will put us in a better position to consider something like this.
