Original typical byond fighting systems are just step in front and punch, use an attack that covers an area... Well that is too old school for me so i just added a targetting system, and projectile attacks will either go towards that target, or a range in front of you. Some might even do random areas on the screen depending on the attack.
Regardless the game will have it's own completely original targetting system based off a friends design. It'll make fights even look cooler aswell as making it easier to melee.
