Just in case you need some code for an MMO platformer. (Not Finished) I'm going to add wall jumping or double jumping in the next update WASD or arrow keys to move MUST HAVE ANOTHER SCRATCHER TO USE MULTIPLAYER, OR JUST OPEN IN ANOTHER WINDOW IF YOU ARE TESTING IT!!!
I'm working on making this into a game btw, so change up the level a little bit so that it's not the same as mine. Also, if you want to use this, I would recommend checking in every once in a while to see if I made any improvements. Big thanks to xamuil2! They helped with most of the code for this test! Check out their channel with tutorials for many variations of Scratch games!
