I’m making a simple character with blueprints. Here’s my code :
It works well but the pitch component rotates the player in its entierty, and makes the camera go in walls. How to fix this ? Adding axis values to camera doesn’t really work 
I go over basic player movement set up in this video: UE4 Tutorial: multiplayer soccer, adding force to actor - YouTube
The portion relevant to your question starts at the beginning and goes through to 8 min mark.
And how can I do that the camera doesn’t flip around ?
this is absolute HELLL
WHY NOTHING WORKS
Have you check out this setting?Its inside character detail,its used with first persn case,
Whats your springarm setting?Usually people dont update camera directly,update springarm.
unreals way of third person machnics is indeed not friendly to understand even their tutorial didnt make clear the key part,just follow the tutorial,go deep when you know enough
