Okay, I am now working on the description when the door is interacted with (locked, and once unlocked).

Code: (Select All)

AddEntityCollideCallback("Player","PrisonDoor","CollidePlayerWithPrisonDoor");

    AddEntityCollideCallback("Player","castle_arched01_1","CollidePlayerWithcastle_arched01_1");

void CollidePlayerWithPrisonDoor()
{
    if(HasItem("PrisonKey") == true)
    {
        SetMessage("Use your inventory to select the key and use it on the door.", 10);
    }
    else
    {
        SetMessage("You will need a key to open the cell door.", 5);
    }

}

void CollidePlayerWithcastle_arched01_1()
{
    if(HasItem("key_1") == true)
    {
        SetMessage("Use your inventory to select the key and use it on the door.", 10);
    }
    else
    {
        SetMessage("You will need a key to open this door.", 5);
    }

}

The game crashes upon starting when I use the code above. I got this off of the script functions wiki, but I may have used it the wrong way.

EDIT:
I would also like to know how to properly name in-game items, such as keys, so that it shows up both on-screen when the player is close enough, and in the inventory.
