I'm trying to make a sample game with 3 or 4 sprites. The problem is the character collision with floor is not very precise when it comes to gravity (pfread function). I have seen in similar threads that you have to divide by a specific number depending on width and height, but i can't get it correctly.   I use multisprite kernel with pfread. Here's what i got so far: Sample.bas  Sample.bas.bin   Any suggestions? Thank you.
