Need help setting up one time terrax tint event

I am currently trying to create an event that uses the terrax lighting "Tint fade #777777 5" plugin command ONE time when first activated then each time after that it goes to the "Tint set #777777". So that basically if a player is in the forest when the tint changes they see the slow fade to darkness but every other time they enter the area the tint stays at the same darkness level and does not fade.

I can post screenshots of the event (as far as I got) but I think I'm kinda making a mess of it. Maybe use some command to "end" the event that fades it in after one use?

Humm... As the note is the same wathever event page you're on, I guess the way to do this would be to set ut two different events: the first one with the tint fade command would turn a switch on on its first page and delete itself on its second page, which would be activated by the switch; the second one would delete itself on its first page but would go on with its second page, which would also be activated by the same switch.

Is this clear? Though not very elegant, I guess this would work, though again I haven't tested it, so I don't know for sure if it would work.

I tried something like this but it got really convoluted and turned into an event-pretzel, heh. I'll try this and see if it works, thanks. How do you make an event delete itself?

It's one of the normal event commands available: "Erase Event", on the second command page, under "Character".
