Hello! I started mapping very recently and I wanted to know why some walls like that wall on 4demo 2nd to last, or the wall on jump_start last, or the tiny wall on jump 2 of ofc, why they all wallbug like crazy. Like you just go on them and will wallbug a lot 100% of the time, not like the ice wallbug where its only a specefic spot, those wall wallbugs everywhere and you wont have trouble hitting the wallbug.
So i decompiled 4demo, deleted everything on the map except the wallbuggy wall, made a box around it to seal it off the void, compiled that, went in game and the wall was still wallbugging. I then move it a couple units, and that removed the wallbug. Mohr also was trying stuff with his wall on ofc, and I had the idea (Boshy kinda suggested something similar but boshy is gay) to move the wall that i had from 4demo, to exactly the same coordinate on the hammer grid as the wall on ofc. Ingame, the wall wallbuged!
We then created a new vmf file, made a wall at those coordinate, wich is 8208 units north of the origin and the wall does wallbug! Doing the same and making a wall at 4demo's coordinate gave the same result: wallbuggy wall.
After some testing, we can now say that any wall created at 8208 unit north of origins, 2056 north and east of the origins and the coordinate of 4demo that i lost but might be 4112 unit south of the origins, it all wallbug. I think its safe to assume that taking any of those number and making the wall east, south, west or north would all create a wallbuggy wall, seeing as 2056 works in 2 direction, but we didn't test it.
We didn't figure out a pattern for coordinates, either its completly random, or someone that know stuff can figure it out. We don't know why it happens either, it just does. If someone would know why this happens, it could be interesting and we could figure out exactly the corrdinates that works.
The thickness of the wall does matter a bit, but the width doesnt from what we've seen. Increasing or decreasing the thickness of the wall by a very few unit kept the wallbuggy wall, but when we kept making thicker it eventually stopped wallbuging. So there's probably a range of a few unit where you can put your wall and it wallbugs, it's not exactly unit precise.
So ye, it's now possible to make a jump based around this kind of wallbug if you just make it at the right spot on the grid. Jump_wallbug when?
