So, to start off, the shooting animation should be faster, because I could back up all the shots because of the guns animation. Your events could be more compacted to. You have 3 events for the same object. I would put all of the events for the "gsg9" object in a big do together. Hitting the enemy was pretty hard to. But this is a good start. Thats all I can say for now, because there is not much in it yet. So, keep working at it. I hope this all helps. Ask me if you need anything else. But for the week, I will be away so anyother week should be good.
I think that you wouldl change to WASD movement if your going to be making an FPS that uses the mouse to shoot. Don't do strafing, just make WSAD move the camera like the arrow keys did. That way you don't have to use a mouse look system until your more advanced with alice. Also, make the shoot animation faster, add some hands cause that would make things look more realistic. Next make it so that when you shoot an invisible sphere comes forwards and backward really quickly. This way people have to aim, not click on guys. More realistic that way.
