# Trigger
You can compose triggers using already created triggers as internal conditions of other triggers. By combining in this way you can create your own events in the game. Triggers of this kind work according to the same principles as other trigger conditions:
* When all internal conditions of a trigger are met, it is considered to be working
* When at least one condition is not met - it is considered to be non-working. Triggers can be combined using the same Boolean expressions and groupings as in regular triggers
As in other triggers, you can use all trigger modes.
#### Started
Trigger activates as soon as all internal conditions of the trigger have been fulfilled and the trigger has started its work.
#### Continue
Trigger activates as soon as all internal conditions of the trigger operation have been met and the trigger is still operating.
#### Ended
Trigger activates as soon as all internal conditions of the trigger have been fulfilled and the trigger has stopped executing
Trigger links from triggers in Game Flow actually use such triggers . You can choose to use this trigger in a more convenient way.
