Need help with script involving making trees appear/disappear

[Statyk]

First, you need to make the trees into entities, and go you Edit>User Defined Variables. Change Type to Object and SubType to Static. Save and put those in your story, as well as fix the names. The SetEntityActive doesn't work for static objects.

Then in your script, change

void tree_door(string &in asParent, string &in asChild, int alState)

to

void tree_door(string &in asEntity)
