[Quotentote]

Hi there its me again :c

i just want to make a lever opens a door....these door that can slide up... i searched the wiki and the forum and tried this:

PHP Code: (Select All)

void OnStart()
{
SetEntityConnectionStateChangeCallback("lever_open_01", "openbigdoor");
}

void openbigdoor(string &in asEntity, int alState)
     {
     if (alState == 1)
     {
        MoveEntityToArea("door_valve_open", "ScriptArea_1", 5.0, 1.0, 0.0, "door_opened");
     return;
     
     }
} 


i know that something is wrong, but how can i make it work? someone know? :/
