In the game, there are special elements that change the states of specific objects and switch them on and off. They are called triggers. They can have a dozen applications: they may turn on a lift or turn off water in the pipes. The following figure shows examples of triggers:
The following are the basic variations of triggers:
On-floor trigger: It is activated when somebody steps on it and can be either the protagonist or any other robot.
Universal color trigger: It responds to a shot that hits its surface. The trigger is indifferent to the color of the shot. The fact that a bubble has touched the spot is more important.
Specific color trigger: This trigger reacts to shots made of a specific color: red, green, and so one. This can be tricky.
