Ok, nm, i get it now
but it still doesn't work...
maybe if i show you my trigger you will see the problem..
I have a car named "truck", and a guy named "player",
in the "player" init field i declared a variable "r1" and set it to false, then i made a trigger in the condition of which i put "Player in Truck", in the On Activation field i put "PlayAight = truck addaction ["Play Aight","aight.sqs"]; r1 = true". I then made a second trigger in the init of which i put, as you said, "truck != player and r1", in the On activation i put "truck removeaction "PlayAight "; r1 = false; hint "stuff"". Both the triggers are turned on as "repeatedly". As you can see i added the "r1", this is because without it the game would right away go to the second trigger and it would not activate that trigger again. Now that i have the r1, it doesnt activate the second trigger at the beggining of the game, but when i get into the "truck", it adds the actions for a second, then removes them with the hint"stuff". My best guees is that there is something wrong with the "truck != player" command... ne one know how to solve this?
