How do you activate an entity after interacting with a door.

[The chaser]

This is development articles. In here there's surely a thread where someone explains you how to do it.

Post in development suppport, please.

Of course it's possible. It should be like this:

SetEntityPlayerInteractCallback("Door", "func1", true);

void func1(string &in asEntity)
{
SetEntityActive("Whateva", true);
}
