That was cool and interesting to look at so a Droideka could be kinda like Galak in the sense that he could keep his shield up to shoot unlike the Assassin droids.

I only mentioned assassin droids as an example because I believe they are the most simplest users of shields in jka game. The trick is to recognize enemy/droideka blaster bolts in the script. Then the shield will know which blaster bolts must be passed and which blocked/reflected.

Or source of droideka blaster bolts can be right before the shield... The simplest solution is usually the best, lol. 

We'll be doing the droideka for Game Update 2.2 (the update after this one)

You can create your own droideka class based on game source, but I believe this requires a lot of work and research. Assassin droid can use shields for example and they are more easier to understand than Galak because of less complexity.
