hi. I'm https://scratch.mit.edu/users/fireincarnate/, and i'm making a platformer. but i need to set the costume in the walking block, and they're both custom blocks. but it's not letting me put the "set costume" block in the "walk" block, and i want that to be over. little help?
You can. Just navigate to your block on the left pane (make sure you set it's category!) and drop it inside the other one.
Yea, I don't see why you can't do this. You can even do recursive calls with the same block.
