Well, I’ve tried sprinting while jumping in BM several times, and it’s time to face facts - I can’t. Is there a correct button combination? Because it just doesn’t seem to want me jumping while sprinting.
Maybe it’s a problem with your keyboard? Stupid ghosting. You could try changing your key setup, but I’m sure that;s not very ideal.
I can sprint+crouch+jump while also prop-surfing and brush-clipping in midair while using the crossbow aim to shoot a snark from 200ft away.
But seriously, it’s true that it could be your keyboard but also some keyboards have specific combinations you can’t do (like shift+up+left works but not shift+up+right) you could also download an auto crouch jump script somewhere on these forums.
