I wonder if "wallclimbing" can be considered a glitch btw. Yes, it's not how the character should be moving, BUT it's not achieved by abusing specific key combinations etc, it frequently happens by itself and I think most of you are familiar with it. Here, I made a demo with Amazon at Mines Of Kelbegen (not with purpose of really speedrunning Mines, just showing these few tricks).
You've just named it, therefore given it official status of existence as a bug along airclimbing and breakdancing :¬)
Seriously - it is a glitch. You cannot walk on the 78° slope (yes, I measured it). It has to be said that it is not physics glitch though - you don't abuse physics as such (like you certainly do in airclimbing) but rather imperfectly, not to say poorly programmed walking on inclined surfaces. My hypothesis (not to be confused with theory
) is that it's caused by wrongly calculated/assumed position of feet on surface (engine thinks you are actually bit farther than you really are) or by wrongly calculated friction force on the surface or maybe both. Note that it certainly has something to do with friction because it may happen on surfaces with specific textures, textures for which high coefficient of friction is assigned, like those rocks in Mines of Kelbegen. Anyway - it's my guess, I can't dissassemble engine :-> . It's still intelligent guess, I can't prove it so it's still a guess. Even if you can show empirical application and performance of it (quite like Huber's hypothesis aka Huber's equation
everyone is using it to calculate strength of materials but it's still is a hypothesis)
