Prison Architect Version 2.0 released
Posted by Chris on 26th August 2016
Prison Architect Version 2.0 has been released!

TWO MILLION players have now enjoyed Prison Architect. We are flabbergasted. We would like to thank every single one of you from the bottom of our hearts, for making this such a dream project.

After six years of development including over 40 monthly updates, this is the final content update for Prison Architect and the final video. We will of course continue fixing bugs and providing support. We are going to take a break for a little while, but we will be back soon with our next game.


Developer Tools and Cheats
Developer tools and cheats, seen in some of the alpha videos, are now available to everyone.
A new option is shown when creating a new map, "Enable Cheats". This is prison specific and cannot be disabled later.

When enabled:
- All construction occurs immediately
- A new 'Spawn' toolbar button permits instant creation of any game object for zero cost
- Water can be placed like any other material
- Research in the bureaucracy screen can be sped up by holding down the right mouse button on the item

The Function keys now perform debug services:
F1 Edit world properties (Very easy to crash/ruin the game)
F2 Profiler
F3 Script Debugger
F4 Dialog Editor
F5 Sound Editor
F6 Sprite Bank Editor for Needs icons
F7 Sprite Bank Editor for User Interface icons
F8 Sprite Bank Editor for Game Sprites
F9 Debug rendering options
F11 Enlarge Map in All Directions

- Cheat prisons do not allow achievement unlocks
- Cheat prisons cannot be sold for profit.

Policy Window (continued)
You can now set which misbehaviours warrant an increase or decrease in prisoner security.
For example, murder can be set to immediately make a prisoner Max-Sec.

You can now disable the cell quality checks that determine which cells a prisoner can be assigned to.
When enabled, prisoners who misbehave will not be assigned to a nice cell, even if that nice cell is the only one available.
When disabled, prisoners will always be assigned to free cells if that is all that is available.

Modding System (continued)
- Added World.NumPrisoners and World.Capacity. These return tables containing the current number of prisoners
and the total number of cells in each security rating respectively.
- Added ability to use markers in object tooltip strings (via objectTable.Tooltip). See lua_function_list.txt

- Localisations: All languages updated.

Prison Architect Update 8 (v2.0 preview)
Posted by Chris on 27th July 2016
Prison Architect Update 8 has been released. Non-steam users can download the latest version from the builds page here:

STEAM USERS: This update is on a steam branch, meaning it will not automatically download. You must manually switch to that branch to see this new version.
- Right click on Prison Architect in your games list
- Click 'Properties'
- Click 'Betas'
- Select 'v2preview' from the list. (Restart steam if it doesn't show up)
- The update will then download.

You need an active forum account to access the builds from our website. If you haven’t already done so, please register your game here to gain access to the builds, the private forums, the bug database and the wiki.

This is a preview build of the v2.0 features that we are properly launching next month. There may be a couple of bugs and glitches in this bad boy so only dl if you are proper brave.....

New improved User Interface
Many user interfaces have been redesigned to be clearer, more consistent, and better looking.

- Improved Build toolbar
New look build toolbar for with much cleaner icons and graphics
Toolbar now filters out locked items by default, leading to simpler menus in early game (Click + to reveal all)
The Room toolbar now highlights room types when you mouse over them
Help tooltips have been added to many of the toolbar menus

- Tooltip sizes made more consistent and screen friendly across the board

- New Context Menu
Click on any object or entity to bring up the context menu
Allows for quick context sensitive actions
Prisoner Rap sheet now auto-follows prisoners

All construction work is now covered by a global UNDO button at the bottom right of the screen
Click UNDO to gradually reverse any decisions you have made, and receive a full refund
Nb. UNDO button is only shown when using the toolbar for foundations, materials, objects, utilities etc.

- Research/bureaucracy screen improved to look better
- Patrols interface improved for clarity
- Pipe and water rendering improved for clarity
- Informants window improved by moving the list to the right of the screen and making it smaller
- Logistics views now more consistent, showing only objects and entities relevant to each view.
Eg Food logistics now shows everything relevent to food: Ingredients, meals, chefs, prisoners working in the kitchen

- Nb. All of the new GUI features can be disabled through Main Menu -> Options -> Game -> Version 2.0 GUI tickbox

- Zoom to mouse
Nb. Can be disabled through Main Menu -> Options -> Game -> Zoom to mouse.

Modding System (continued)

- 'Infinite' mod loading
The game now supports many more simultanious graphical mods than before
It achieves this by gradually increasing the size of the graphics tileset, until your graphics card itself hits its limit
In general users should find they can now activate a great deal more mods before any problems occur
In addition, when the limit is reached you will now receive a warning/error message. (Previously it just started misbehaving)

- Mods with spritesheets larger than 1024x1024 are now supported

- Lua World Scripts
Each mod can now have a data/world.lua script file, which should contain both Init() and Update( timePassed ) functions.
This script is initialised on World initialisation (for both new maps and loaded save games) and Updated on each World update.
Variables set in the "this" or "World" tables will be cast to strings and persist in the save game.
Variables are loaded after Init and before the first call to Update.

- Mods can now have their own sounds.txt file, containing only new/modified sounds.
These will override base data in the same way as other mod files.

- Added Update button to Prison Sharing menu.
Allows any published prison to be updated with the prison that you are currently playing.

- Fixed a bug in the lua scripting system that would try to cast boolean strings (in lua) to a bool (in c++).

New game content
- New events
Contraband surge
Tree fire
Food poisoning
Agitating radio
CI list leak
Mass tunnelling

- TVs now broadcast over an area (3x3, shown as a green box).
Prisoners sitting within the viewing area can watch TV and thereby have their recreation needs taken care of.
Nb. Prisoners can be doing other things at the same time, eg eating in the canteen.

- New item: Large TV.
Has a larger viewing area and can easily provide Recreation to an entire room.
Be sure to provide lots of seating spaces.

- Radios now passively broadcast to the entire room.
Any prisoners in a room with a radio are slightly less bored, so get a small reduction to their Recreation needs.

- New item: Arcade Cabinet
Two inmates can play games on an arcade cabinet at the same time

- New Contraband menu option: 'Stolen From'
Shows the location each item of contraband was stolen from, rather than where it was ultimately recovered
Shows 7 days of contraband history.
This is very handy for finding which of your rooms is lacking security
Also easily reveals where contraband is being thrown into your prison.

- New Regime options
Added a 'Work/Lockup' regime type. Treats prisoners who aren't working as being on a Lockup regime instead of free time.
The standard Work regime has been renamed to 'Work/Freetime'

- Dead entities now have their cause of death displayed in their tooltip

- Prisoners without jail cells now show the reason why in their tooltip

- Family cells that are in their own block, separate from other prisoner housing, will form a single sector

- The 'Names in the Game' database can now be manually updated from the Extras | Name in Game menu.

- Updates to all translations to bring all languages up to v2.0.

- Fixed: A gang would never receive a new leader, if its previous leader was killed and left the map.
- Fix for Intake System to ensure that the correct number of prisoners are taken
- 0010443: [AI & Behaviour] Family cells do not form a continuous cell block
- 0010559: [Mod System] Changing WorldCell "Ind" property always sets to false
- 0009556: [Mod System] Lua: Triggered property sometimes a string, sometimes a number, sometimes boolean
- 0003033: [Save & Load] Steam Workshop Update not possible
- 0009729: [Mod System] Sprites.png: 1024x1024 size not working
- 0010882: [Mod System] Sprite.png size limitations cause compatibility issues with mods
- 0010290: [Mod System] Sprite Limits
- 0009618: [Mod System] sprites.png: current approach necessary but not sufficient

Prison Architect update 6 released - and NEW GAMES from us
Posted by Chris on 29th April 2016
Prison Architect Update 6 has been released. Steam users will be automatically updated. Non-steam users can download the latest version from the builds page here:

You need an active forum account to access the builds from our website. If you haven’t already done so, please register your game here to gain access to the builds, the private forums, the bug database and the wiki.

Introducing 'Scanner Sombre' and 'Wrong Wire'

Skip forward to 22 minutes into the video, to see us demonstrate two of our (potentially) upcoming games. These are prototypes we have been developing in secret until now, and will form the basis of whatever comes next after Prison Architect. Please keep in mind that whilst we intend to continue supporting Prison Architect with updates for a very long time, we also intend to make new games, just as we have always done.

We are interested in your thoughts on the new games. Please go here to vote on your favourite:


= Seasons and Weather
- The game will now move through the seasons, with the outdoor temperature varying based on the time of year.
- Various weather patterns can occur during the game, varying based on the current season.
- Overcast
- Rain
- Torrential rain (Special event, rare)
- Snow and frost
- Heatwave (special event, rare)

- Prisoners needs will be affected by the weather when they are outdoors. Getting rained on will spike their
comfort, clothing and warmth needs.

- Prisoners left outside in extremely cold conditions (for example in an outdoor solitary confinement cage)
can now die of exposure.

- Weather is DISABLED by default in all prisons, and can be enabled when creating a new map.
Alternatively, use the new "Map Settings" screen in the Extras menu.

= Map Settings
You can now adjust the settings of your prison from a new screen called "Map Settings", found in the Extras menu.
This screen lets you enable certain options that may not have been enabled (or even available) when you first created the map.
Nb. You can enable these options, but you cannot disable them once enabled.

Available options:
- Enable Gangs
- Enable Events
- Enable Weather

= Job Prioritisation
- You can now mark any job as a high priority. Simple hold control and either
left click or left drag a selection to mark jobs. Available workers (who aren't
already on a high priority job) will stop what they are doing and be assigned
to the high priority job.

- If no workers are available, high priority jobs will take precedence when the
workers become available. A small icon in the lower right of a visible job shows
if it is marked as a high priority job.

- You can remove the high priority marking on jobs by holding control and either
right clicking or dragging a selection.

- Hovering over an in progress job will now highlight the entity working on it,
showing a red line leading to the worker responsible for the job.

- Pressing F while highlighting an in progress job will cause the camera to follow
the working entity and keep the highlight active.

= Performance Work (continued)
Further performance gains were made this month through several different approaches to optimisation.

- More systems moved to overlap with Render().
- Optimisations to the visible object list builder.
- Singly linked lists mostly replaced with arrays (FastList).
- Avoid copying of containers where possible.
- NeedSystem optimised.

= Bug Fixes
Temperature and lightmap system corruption bug fixed.

- 0010618: [Gameplay] Temperature next to fire is in the negatives
- 0010625: [Gameplay] Temperature drops instantly even in areas that should be producing heat
