i have this bullet casing coming out of my gun socket but no matter what rotation i put the socket on the bullets always came to my camera position
how can i fix itt :((
Hi man,
i think that dont matter the the rotation of the socket, the particles are oriented based on their behaviour,
I am not an expert but you can make the particles do a lot of things ,change shape and rotation … .
i often confuse them with some billboard behaviour so you have to check out some tutorials or these manuals!
It’s all particles! I have projects with the same particles and i can orient them with My sockets 
i’m using the sidescroller Game mode
here a discussion about particles orientation
