This past weekend I attacked UE4's Blueprint system head on, and got nearly every one of my mechanics up and running. Players can grab and drop the ball and shoot blue objects in order to trigger a set movement that varies from object to object. Placing the ball into tubes next to locked doors will open the doors, and the walls I've eloquently dubbed "ball zap walls" will destroy the ball while allowing players to pass through. As you can see from below, the first room is completely functional, with the exception of the ball dispensers. Next week I hope to be back with the second area up and running as well.
