• Other minor bugs

• The play button on the maps menu. Just double click the map icon.

• Lava map
  
• Lava pool to Hybrid
  
• Buttons have a double trigger mode
  
• Underwater objects may transfer charge to other near underwater objects
  
• Tempered glass pane
  
• You can hold M (can rebind) while using pins to snap to the center of mass of the undelying object. This is useful for things like putting pins in the exact center of wheels. It also magically allows you to put pins outside the object. This may be extended to other tools in the future, but it's just pins for now. It's pins.
  
• Liquid container pressure now travels through valves and such. This may introduce some unfamiliar, however correct, behaviour.
  
• ModAPI.OnLinkCreated and ModAPI.OnPinCreated events. The modding wiki is being worked on intensely so these events may not be documented for a while. They are invoked when a link device is created (currently only the phase link) and when a pin is created, respectively.
  
• Partial proper documentation: https://www.studiominus.nl/ppg-modding/internalReference.html. It isn't completely done yet so there may be some issues. Not everything has an explanation yet but I have done the most important parts.

• Rewrote button behaviour
  
• Default value for "Liquid overflow limb exploding" setting is now "Disabled"
  
• Made the "Pacifist" achievement less strict.
  
• LMG belt is now lighter
  
• Minor texture changes
  
• Hybrid thumbnail change
  
• 
  Extended environmental setting numerical limits. Gravity can now go from -200 to 200. Ambient temperature can now go from -100 to 9000 degrees C
  
• ExplosionCreator.CreateExplosionWithWater no longer asks for a water surface level

• Human visual wound serialisation issues
  
• Acid inconsistencies
  
• Limb crushing inconsistencies
  
• Impact intensity inconsistencies
  
• Performance improvements
  
• Center of mass indicator bugs
  
• Resized wings violating the laws of physics
  
• Incorrect layering of worm staff worms
  
• Syringe and other stabby item problems to do with limb crushing and disintegration
  
• Pink enhancing serum can no longer weaken limbs
  
• 
  Major water bugs (this changes the WaterBehaviour significantly and if your mod depends on this then it will break)

• That "Made it easier to grab moving objects while following them" thing because it actually made things less easy

Preview 1.20 is now live on the preview branch.
Please report any bugs here and follow the instructions carefully.


I am no longer gone. I was taking a break as suggested. It was cool and all but I didn't sit around doing nothing. I've made good progress on the proper documentation for the game. Thanks for waiting.

• That "Made it easier to grab moving objects while following them" thing is gone because it actually made things less easy

• Setting to disable liquid-overflow-limb-explosion

• Syringes won't push liquid into a limb if it already has some in it

• Keeping syringes in a human for a prolonged amount of time will no longer destroy them
  
• Minor performance improvements & bug fixes

• Limbs explode if pumped too full of liquid
  
• Water breathing syringe
  
• Fusion bomb
  
• Mystery liquids
  
• Liquid valve
  
• Nuclear weapons may destroy electronics if in line of sight

• Made it easier to grab moving objects while following them
  
• Drastically decreased the capacity of the tank in a car
  
• Made humans a little stronger
  
• Atom bombs glow a bit
  
• Beings don't start panicking the moment they're under water
  
• Rewrote limb connectedness system.
  [expand type=details]
  For mods, this means that
  CirculationBehaviour.IsConnectedToMainBody
  and
  CirculationBehaviour.IsDisconnected
  are obsolete (still available with behaviour unchanged). Use
  Limb.NodeBehaviour.IsConnectedToRoot
  instead.[/expand]

• Camera locking bug when following things
  
• Beings being able to live without blood
  
• Minor bugs
  
• Incorrect temporary body liquid behaviour
  
• Weird spawn silhouette delay bug

• Rope
  
• Stronger spring variant
  
• Empty syringe
  
• Ceiling sentry turret
  
• Mending syringe
  
• Hold the spawn key when spawning contraptions to see their silhouette before placing them down. This only applies to all contraptions saved in or after this version. This also applies to copying/pasting using the shortcuts.
  
• Empty syringes can push, pull, or be idle. Just like the blood tank.
  
• Limbs no longer have an upper bound on their liquid capacity.
  
• Liquid identifying machine. It displays the make up of its contents.
  
• Blood tank context menu options for each mode
  
• Gate "max power" property that you can set using the context menu.
  
• Minor details to most maps
  
• Brightness setting

• The entire syringe system. This will destroy all syringe mods created before this version. All syringe behaviour is now based on liquids. Syringes are liquid containers and every syringe effect is the result of foreign liquid entering the circulation. All syringes, except the empty syringe, are infinite.
  Attention to modders: you can derive from "OldSyringeBehaviour" instead of "SyringeBehaviour" if you want to keep using the old system.
  
• Almost all spawnable item thumbnails
  
• Map ambience is now stereo

• Underground tunnel in Hybrid is better lit
  
• Syringe appearance
  
• Made rope catenaries more accurate
  
• Minor performance improvements

• Some platform specific overrides
  
• Audio sliders not updating the volume while sliding
  
• Gate not having the correct threshold input dialog
  
• Odd transmitter sound artifacts & other issues
  
• Framerate dependent splash effects
  
• Potential audio clamping bug
  
• Major liquid system problems. This may influence older saves with humans in them.
  
• Major serialisation issues
  
• Blood tank drain particles being the incorrect colour
  
• The inspector window "blood amount" value no longer counts other liquid types
  
• Shotgun collision boxes
  
• Abyss uneven platform height

• Minor bugs

• Pink Syringe fog particles
