Mouse, space to shoot. *Pressing the "c' key activates weird pen designs (I accidentally discovered it).
This is a test that I made sometime around March (would've been on my test account). It was half-finished and did not work, so I decided to work on it again and I finally completed it. What this project includes is an "auto-aim" system that chooses a target to attack based on distance. However, the targets are all clones, which required extra scripting and position recording of individual clones. But this is what makes my project useful, as it is flexible enough to deal with any number of clones.
