Arcade Collision Problem - randor - Oct-28-2019
Hello all,
Ok, I found Python Arcade and wanted to play and see what I could come up with. I have been following some tutorials and videos but most of the ones I found are using the platform physics engine, I want to use the simple and do an overhead with character animation moving in 4 directions.
I got as far as below, but for some reason, if i move left or right until i hit a wall, then try to go up or down it shoots the player off the screen and gives me :
Quote:Error, collision while player wasn't moving.
I found another thread that was similar but his issue was fixed by not calling the player.update() method, which I also took out, but it still happens.
the weird thing is it only happens when i go left or right then up or down. If i go up or down to the wall, then left or right it works fine.
