is it normal for a beginner to hit walls?
i mean whenever i try to bunnyhop( cause ive learned a bit) i always hit a corner and get stuck there. Are there any tips in order to avoid this or am I just being stupid and talking nonsense?

Yes, but you'll get used to it eventually. Just don't hit the walls.

It's the most annoying thing ever... it takes practice to predict when you can turn and how . dont worry =)

yeah just keep jumping around on the popular maps and you will get a grip of them quite fast. you can turn quite a lot while being in the air so keep that in mind

Maybe this can help in some way:

Just play some pickup matches and use the prewar time to jump around. You'll spend HOURS without noticing... or no, you'll notice but you won't hit the walls anymore soon.

Actually I hit the walls in that one, I'm such a n00b

you must feel the jumps and trajectory. only practice can give you that feeling!

I not bunnyhop and still hit the walls and get stuck on corners......
