This article is about the Prison Architect save file Format ".prison" file. Its aim is to document every parameter of the save file.

The save file consists of organized, human readable text, and can be edited with a basic text editor. Editing the save file can be used to change some settings, hack in something, fix some glitches & bugs, and of course, to cheat.

Basics and FormatEdit

Prison Architect is a 2D game. It uses X and Y coordinates in a grid format. In game, X is left-right, Y is top-bottom. The save file contains "Head" entries followed by multiple "BEGIN ... END" block entries. Some of those entries have more "BEGIN ... END" block entries inside them.

.prison Edit

The .prison format is the way games are saved in Prison Architect. They are very simply put, just .txt files. The .prison file defines all features of a prison, including the progress of Research and the daily Regime.

Location Edit

Save files can be found from the main menu in Prison Architect by selecting the "Open Save Folder" option. Alternatively, save files can be found in the following locations, depending on the operating system being run and the version of the game installed (e.g. Steam vs standalone):

OS Location
Windows (General) %localappdata%\Introversion\Prison Architect\saves\
Windows (XP) C:\documents and settings\your-username\local settings\application data\introversion\prison architect\saves\
Windows (Vista or 7) C:\users\your-username\appdata\local\introversion\prison architect\saves\
Mac OS X (10.6+) ~/Library/Application Support/Prison Architect/saves/
Linux ~/.Prison Architect/saves/

General Concepts Edit

Each object is given an Id.i and an Id.u, which are two separate identifier numbers. Id.i is unique to that object type while Id.u is unique to the whole game. The next Id.u to be used is stored as ObjectId.next.

Format Edit

Header Edit

.prison files begin with a header of basic information.
Some of your entries might be missing. This happens when they match their default value. You can still add them manually to the save file if you wish to change it's value.

On the forums, Chris has stated that adding the text below will make it so "All materials will be delivered by truck, and your workmen will spend a lot of time unloading them. Workmen will no longer be able to teleport materials around"

NumCellsX specifies the width of the game area and NumCellsY specifies the height of the game area. When altered to a larger number, the map increases downward and to the right, the defined number of tiles. When the size is decreased, all items that were beyond the edge of the map are visible on the very edge of the newly sized map. If the map is increased once again, the original positions of the items are retained.

CellsEdit

This entry stores data after the "Header" data level. It defines what material is located in a tile location. If a map is 200x160 tiles in size, "0 0" refers to the top-left most tile, "0 1" is the second tile below the top-most tile, "199 159" will be bottom-right most tile.

BEGIN Cells      
    BEGIN "0 0"        Mat PavingStone  Con 37.8430  END
    BEGIN "0 1"        Mat Sand  Con 18.5168  END
    BEGIN "0 2"        Con 6.91396  END
    BEGIN "0 3"        Mat PavingStone  Con 31.9050  END
    BEGIN "0 3"        Mat BrickWall  Con 58.4516 Ind true END
    BEGIN "0 4"        Mat Grass  Con 78.3275  Room.i 27  Room.u 277797  END
END

The first two numbers are the co-ordinates of the cell in question.
In the above example, cell [0,0] is made of paving stones, whilst cell [0,1] is sand.
If a cell is considered 'Inside' the cell will contain an attribute 'Ind' with a value of true. This will be absent for outside cells.
Each cell also contains a reference to the Room ID and Unique Id if it forms part of a room.
