I am attempting to create a unit (robot) that can only move when the robot loads a unit (pilot) inside it. The robot has 1 cargo hold capacity, and only the pilot may enter. I have a trigger for when the pilot gets inside the robot, the robot is then able to move by setting its movement speed. How would i make a trigger for when the pilot gets out of the Robot and the robot then is unable to move unless the pilot gets back inside? (Neither the pilot or robot are in the editor at the beginning of the game, and the pilot builds a building which trains the robot)
