Hi Reltzu,

you're on the right track, you need to set an event name for the trigger in the sidebar and then use that (instead of the GUID like with the story editor) to make it work. For example with the event name "ScriptTest" like so: https://i.imgur.com/igD4WPw.jpg and the script like so:

Code
EVENTS

EVENT EventTriggerTest
VARS
	CHARACTER: _character
ON
	// OnTriggerEnter(_character, _, "TRIGGERGUID_EventTrigger_000_47617a86-d08a-4d10-8698-8670e534d1d9") <-- doesn't work
	// OnTriggerEnter(_character, _, "EventTrigger_000_47617a86-d08a-4d10-8698-8670e534d1d9") <-- doesn't work either
	OnTriggerEnter(_character, _, "ScriptTest") // <-- works! :)
ACTIONS
	DisplayText(_character, "TriggerTest :)", 3)


At least that is the only way it works for me.
