Trigger
A trigger is a signal, usually a single glider, that collides with a seed constellation to produce a relatively rare still life or oscillator, or an output spaceship or other signal. For example, all turners and freeze-dried constellations are triggerable. The seed constellation is destroyed or damaged in the process, unlike a circuit or reflector which recovers completely and can be re-used.
In the pattern below, a trigger glider strikes a dirty seed constellation assembled by Dave Greene in January 2018,[1] to launch a 2-engine Cordership.

"Trigger" is also used when a spaceship reacts with another object to cause a reaction to occur whenever desired (but perhaps only at particular intervals). The object being triggered lies dormant until the reaction is required.
