Weapon doesn't move after camera

I started with the FPS project , i have done some minor changes : from youtube gun sistem , main menu , a second level and deleted the UE4’s already done UI (crosshair) which were a problem when starting the menu . God knows how but now the gun won’t move with the camera up and down , only left and right . how can i fix this ? I also wanted to use a weapon sway but that doesn’t solve it: UE4 Weapon Sway / Delay Tutorial - YouTube

When i ckeck : use controller rotation:pitch , yaw and roll the gun is moving rock solid with the camera but the weapon sway won’t work .

It still doesn’t work , i think the problem lies way down , when i do a new fps project the default selected is only ,use controller rotation yaw" , my project with ,only controller rotation yaw" selected wouldn’t turn the gun up with the camera . Anyways thanks for the comment answer 1!

Try “Get World Delta Second” instead of calling Tick

Did you find the solution?
