// door.txt - This is the basic script that powers all doors. If you are 
// working on a scenario that contains doors, DO NOT REMOVE THIS SCRIPT.

// If you place a door, this script is automatically attached to it. The
// default settings for the script are for a basic, unlocked door. To make it
// locked, you will need to change the memory cells.

// Memory Cells - 
//   0 - Lock level. If left at 0, door is unlocked. Otherwise, the strength/tool
//     use needed to get it open. If this is set to a really high number (say, 200),
//     it can't be unlocked by normal means
//   1 - Key needed. If left at 0, no special item helps unlock the door. Otherwise,
//     if that party has this special item, the door automatically unlocks.
//   2,3 - Coordinates for a stuff done flag. If these are 0 and 0, ignored. Otherwise,
//     the stuff done flag is set to 1 when the door is unlocked. If the flag is non-zero,
//     than when the party enters this zone, the door will ebcome unlocked.
//   4 - Town script run when the door is successfully opened.
