A trigger is a virtual entity which executes an action once a specific condition is met.

== Trigger Area ==
 
A trigger has an area. It can be scaled in all axes and it can be rotated around Z (up) axis. Some areas have unlimited height by default, but that can be changed by manually adjusting their vertical scale. Setting it to negative value will make them unlimited vertically again.

You can see it visualized both in the scene and in the map, but by default you cannot interact with it. However, when the trigger is selected, you can drag it by its area in the map.
[[File:3den_triggerMove2D.gif|center]]
 
 
== Activation Condition ==
 
The activation condition can be based on the trigger area (e.g. no OFPOR present within a 500 m radius), but a scripted condition or combination of both can be applied as well.
{{Feature|important|Animals are part of the civillian side. That means they can activate triggers which condition is set to "Civilian".}}
 
 
== Trigger Owner ==
 
Use the '''Set Trigger Owner''' connection to assign the trigger to a specific group. It will change the available activation options from the general ones (e.g. any BLUFOR character) to the group specific ones (e.g. any member of the group).
[[File:3den_connectTriggerOwner.gif|center]]
 
 
== Timer ==
 
Using the '''Timer''' attribute, you can set the trigger to be activated either after a certain period of time since the condition has been met, or while the condition is met for the specified duration.
 
 
== On Activation ==
 
Once the condition is met, the trigger becomes activated. Its '''On Activation''' expression is executed, and connected waypoints or modules may be activated as well.
 
 
== Repeatable ==
 
If the trigger is set as repeatable, it will be deactivated once the condition is not met anymore. Afterwards, the trigger can be activated again, and this can continue until the scenario ends.

A trigger is a virtual entity which executes an action once a specific condition is met.

Trigger Area

A trigger has an area. It can be scaled in all axes and it can be rotated around Z (up) axis. Some areas have unlimited height by default, but that can be changed by manually adjusting their vertical scale. Setting it to negative value will make them unlimited vertically again.

You can see it visualized both in the scene and in the map, but by default you cannot interact with it. However, when the trigger is selected, you can drag it by its area in the map.

Activation Condition

The activation condition can be based on the trigger area (e.g. no OFPOR present within a 500 m radius), but a scripted condition or combination of both can be applied as well.

⚠
Animals are part of the civillian side. That means they can activate triggers which condition is set to "Civilian".


Trigger Owner

Use the Set Trigger Owner connection to assign the trigger to a specific group. It will change the available activation options from the general ones (e.g. any BLUFOR character) to the group specific ones (e.g. any member of the group).

Timer

Using the Timer attribute, you can set the trigger to be activated either after a certain period of time since the condition has been met, or while the condition is met for the specified duration.


On Activation

Once the condition is met, the trigger becomes activated. Its On Activation expression is executed, and connected waypoints or modules may be activated as well.


Repeatable

If the trigger is set as repeatable, it will be deactivated once the condition is not met anymore. Afterwards, the trigger can be activated again, and this can continue until the scenario ends.


Triggers are the primary way to design the scenario flow without use of external scripts. Find out more about their configuration in the tooltips of their attributes.
