But I dont know how to make it…
Can somebody reference me a link or give me a basic idea of how to do this,

Rays Directions Dot?

Do something like this:

local lookVector --the direction the humanoid or gun is facing
local shootVector -- the direction the bullet is going

local dotProduct = shootVector:Dot(lookVector)
if dotProduct < 0 then
	print("backwards")
end

The dot product function essentially sees how parallel two vectors are. You can view a visualizer here:
