So, I've been coding half asleep this night. I felt that I had to get back in the railgun code, so that the towers would visualy fire at critters that enters their perimeter. This code also handles gameplay logic in terms of damage, accuracy and targets. I've changed up the structure a little bit for towers since the last version; enough that I might have to rethink the implementation, but at least it somewhat works now. While in this crunch that will have to do until it's at the top of priorities again!
