Movement and Shooting Mechanics

I've completed the movement and started making the shooting mechanics, which are quite rusty and bad. The bullets come from the mouse rather than the player which isn't what I was aiming for (no pun intended). I took to reddit to find a fix and I'll try what I've been told. Development so far is going fast, faster than the 3D projects I was working on before, so this should be out at most July and at least April.
