Hey guys, i was bored today so i thought i'd work on adding in sidestepping.. Now this works, but there seems to be an annoying bug and i cant seem to find a fix for it.. Now, there are two bugs..
First one is that it doesnt seem to be able to register what direction the character is facing until you press the sidestep button a second time.. Meaning that when you press the sidestep button, be it left or right, the character jumps diagonally..
Second annoying bug is that after using the sidestep a few times. Approximately 10 times. The character on screen will slide sideways until it hits the end of the map.. Now, i've seen that before, and i cannot remember what causes it.. I was thinking of maybe an overflow error somewhere, but yeah.. It doesnt pop up with any error messages..
Here is the main engine of the whole sidestepping business.. I dont think it has much to do with this, but yeah.. Like i said, i have no idea whats causing this problem.. It would be awesome if someone could give us a bit of help on this.. Cheers..
Code:
