Development of the Quad Copter game continues! I've set up sequential checkpoint gates as Blueprints that are super-simple for LDs (Level Designers, a.k.a., Me) to place. They only allow the player to complete the checkpoint if they enter from the green side, can be placed anywhere and have a pleasing, rubbery rebound when you hit them :D As you complete each checkpoint, the game looks for the next gate and activates it based on an Integer set in by the LD. The active gate is subtly highlighted and even more subtly deactivated as you fly through it.
I also made a nice, if currently overblown spark effect when your rotors hit something hard :D
