How can I use the "AddTriggerEvent"

There are some Actions in my W.E. called Trigger-AddTriggerXXXEvent.
What should I do if I want to use them?

Umm... That would add an event (A thing that triggers that trigger) to whatever trigger you add it to...
And it triggers the trigger if the Event happens.

those are umswe, and map utility addons. i dont sugest using them untill you are more experianced. they create triggers, and events and actions for those triggers.

Thanks!
