So if I understand right this means that the basic platforming mechanisms are not "pixel-perfect"?
Actually, I looked for such a topic because I am a real noob and started the example "Platform 1 (simple movement)" and noticed that sometimes the player block lands on the black blocks with an empty line in-between. But only sometimes, like 50% of the time (whatever), but it IS annoying since this such an elemental mechanic. (although I understand that it's implementation might be very difficult)
So no easy solution for this I see?
