Valve interaction

[Anxt]

Select the object in the map editor that has the wheel on it. Go to the entity tab, and where it says "ConnectionStateChangeCallback" or something of the sort, type in the TurnOnHeater function name.
Then, make your function look like this:

void Turnonheater(string &in entity)
{
if(alState==1)
{
PlaySoundAtEntity("", "22_fire.snt", "geostove", 0, false);
SetLampLit("bonfire", true, false);
}
}

Get rid of the SetEntityPlayerInteractCallback you have as well, it will mess it up.
