I have collision code that works well. You can't move up or down through blocks. There's also code for walls, but whenever I enable them, moving left and right on tiles is messed up. My game is tile-based, and I don't think the code is really meant for moving on multiple tiles at a time. I'll show my code below:
The above checks for up, down, left, and right collisions. I currently have left and right collisions disabled because movement is janky. This is the code that applies the above:
Any help would be appreciated; especially if you can explain why it wasn't working before!
