I'm really sorry for the long wait I did not have free time at all until now.
So the problem I mentioned before was on my own, really sorry about that. The paperdoll was getting removed because I added paperdoll only to the left and right side of the character. But I still have a huge confusion about that.
The entities are 4 by 4. Up, Down, Left, Right on the regular intersect engine. But I'm not sure of how it works on the platformer edition. Is it possible to see an example, please?
Nvm, here's the answer to my dumb question...
what's wrong with me omg.
