I'm looking for a way that i can set up a projectile event such as a bullet, that once it hits an enemy it damages them or kills them also for different weapons and for different directions.....Can Anyone help!

You might as well get a script for that.. its hard to do.. you have to track the direction of your character, how far out the projectile goes, it's X and y so when X and y= the Enemy's X and Y you it will initiate the event... a script would be better

If your looking for a battle system that has enemies on map that you can shoot at them and such. there you go.
