How do you make it possible to advance to the next level? I can't seem to figure it out.

I can’t seem to figure out how to get the character to advance to the next level. Please help me, I have no idea about the coding, or the output input thing… Any help or advice would be much appreciated.

If you look at my (Currently In Progress) game, there is a Goal (Yellow Circle) and if you go into Edit you can copy that code on to yours.

If you want a portal or something, have a collision and then connect that to a next level behavior
