I haven't been around the forum for a while, been busy with exams and whatnot.
Following Caspis Sinclair's tip, I had a look at Ashley's Instant Hit Laser example and after some tweaking and trying, I pretty much got what I wanted all along(So, I guess thanks to Ashley and Caspis )
Anyway, here's the "demo" for those who want to check it out(the green enemy is just for target practice, so don't worry, when I'm finished, the enemies will be a lot more challenging I hope . Plus, in order to influence him, you need to hover over him with your cursor. I had to do it like that, because collision detection just took to many resources when walking AND blasting at the same time. ):
