Day 2(??)
More progress today. Character arms are movin' and at the proper shoulder joint to boot! Raycasts are being shot when player clicks but most importantly the character faces the direction where the arm is! I'm proud that one mostly because I didn't use a tutorial to make it. 
Next up are the weapons and the accuracy + penetration system. This one'll be hard. I want to get the position of the mouse and the position of the enemies and calculate accuracy depending on how far away the mouse is but I'm a bit stuck. Plenty of time to think about it while I actually implement the weapons.
