Door open script

[The chaser]

The script would be like this:

void OnStart()
{
AddEntityCollideCallback("Player", "name of script area", "Open wished door", true, 1);
}

void Open wished door(string &in asParent, string &in asEntity, int alState)
{
AddPropForce("Name of door", 0, 0, 0, "world");
}
void OnEnter ()
{

}

void OnLeave()

{

}

I don't know what coordinates you should put, but you can test it.
It should be something like this. Hope it helped.
