    A 2nd beta has been released, to fix a critical bug in the previous beta.

    Beta version 96.0 (Build 347) 2021-07-04
    • Fix local saves and data migration process not working on Windows
    • Make ROCK more resistant to DEST (similar to CNCT)
    • Adjust LITH's color

    You can download this new beta from the Download page, but please be aware this is a beta and may have issues and bugs. Here is the full changelog:

    • New element: SLCN (silicon). Sparkles, conducts electricity like GOLD, and has many reactions while in molten form
    • New element: PTNM (platinum). A catalyst in many reactions
    • New element: ROCK (rock, a solid). Melts into a lot of different materials at higher pressures, and is eroded by WATR
    • New element: LITH (lithium). Reactive element that explodes on contact with water
    • New element: VSNS (velocity sensor). Similar to LSNS
    • Add CUST (custom game of life). Custom GoL types can now be created with any rulestring and colors
    • Add reaction to produce BCOL: WOOD at high temperature and low pressure
    • Add Latin-1, Latin Extended-A, Cyrillic, and Hangul characters to the font. Add Composition support
    • Non-ascii characters will be deleted by the website inside comments, save titles, and signs; and replaced with question marks in save descriptions. This will be fixed on the website in a future release.
    • By default, all data and settings are now stored in an OS-specific user data directory. This is "%APPDATA%/The Powder Toy" on Windows and "~/.local/share/The Powder Toy" on Linux
    • Add button in options menu to migrate data to the shared directory
    • Windows: Add shortcut to start menu when installing. Press ctrl+i to reinstall TPT and add the shortcut
    • 64-bit Windows builds are now available, users on 32-bit Windows will still remain on the 32-bit version unless tpt is manually redownloaded from the website
    • 32-bit Linux builds were dropped. If you still need this, you can compile from source
    • Ctrl+u shortcut resets ambient heat
    • Ctrl+a shortcut to select/deselect all saves in save browser
    • Save ambient air temperature and make it configurable in options menu
    • Add ren.showBrush Lua api to hide the brush
    • Add Lua functions to interact with composition: interface.grabTextInput, interface.dropTextInput, interface.textInputRect. Also, new "textediting" event
    • Redo and add type parameter to sim.neighbors

    • Make GLOW element glow under pressure
    • BRAY .life can be customized when firing from ARAY by setting ARAY's .life
    • Remove .life delay feature of ARAY/DRAY as this was historically not possible to use
    • SPRK / METL no longer deleted when inside detector wall, and solid elements can no longer be drawn on detector wall
    • Stasis walls now keep dying GOL cells in stasis
    • LSNS and HSWC can now interact with energy particles
    • Show NONE in {ctype} signs instead of 0 when an element has no ctype
    • Take undo snapshot when using ctrl+x
    • Improve stack pasting behavior
    • Prioritize favorited elements in element search
    • Remove gaps between lines of selected text in multiline textboxes
    • Make username case-insensitive when logging in
    • Replace luasocket with a new socket API backed by libcurl
    • Rewrite tpt.set_wallmap, it can now set FAN wall velocity
    • Return version (aka history index) from sim.getSaveID
    • Make sim.clearSim clear active save information too
    • Return a reason for failure from sim.loadStamp
    • When framerate is uncapped or higher than your monitor's refresh rate, frame drawing will now be skipped. This can be controlled via tpt.setdrawcap
    • Write powder.pref immediately every time a setting is changed
    • Move IRC channel from to in the intro text

    • Fix LSNS being unable to deserialize in all directions at once
    • Fix single-pixel PIPE / PPIP breaking on rotation
    • Fix QRTZ/GLAS/TUNG breaking on load (again), for cases when pressure is negative
    • Fix air being able to go through walls for a frame after undoing
    • Fix GoL sometimes not working for a short time after undo
    • Fix infinite spark loops in photoelectric effect
    • Fix line tool deletion bug when WIND is selected (id:2554353)
    • Fix a bug which caused a line of particles to sometimes be drawn between the cursor and the top left corner at startup
    • Fix typo in "change resolution" option description
    • Fix text glitch in console when writing multiple spaces in a row
    • Fix many crashes triggerable by Lua API functions
    • Lua: Make custom can_move settings persistent
    • Fix 612 SSL errors experienced by some Windows users when using online features
    • Fix icons in Windows Explorer on .cps and .stm files (requires reinstall)

    Do note, this is a beta, so saves containing new elements and features cannot be published. Please take care not to update your saves in the beta, which may make them incompatible with the release version.

    To download the update, either go to the download page, or go to your profile settings and check "Enroll in beta updates".

    Note on shared data directory:
    Starting with 96.0, by default TPT will put all it's data - powder.pref, stamps, local saves, and scripts, in the shared data directory.
    Windows: "%APPDATA%/The Powder Toy"
    Linux: "~/.local/share/The Powder Toy"
    Mac: unchanged (it used the shared directory before)
    Old installations will not be changed, it will still put all its files in the same folder that the powder toy executable is in. If you delete powder.pref, it will start using the shared directory instead. Several mods (Cracker1000's mod, jacob1's mod, TPT-Ultimata) will also use the shared data directory, meaning your stamps, saves, and logins are synced across all instances of TPT.
    If you want to migrate to the shared directory, use the "Migrate to shared data directory" button in settings

    Note on 64-bit Windows:
    64-bit Windows builds are now available. There is no difference between the 32-bit and 64-bit versions, upgrading will not make TPT faster. The only change is that if TPT leaks memory, it can now use more than 2GB of RAM instead of crashing with "bad allocation".
    The default for Windows will now be the 64-bit Windows version. on the Download page will link to this. The 32-bit Windows version will be provided to existing users who update from an older version of TPT.

    Note on GitHub Actions:
    TPT is now compiled via GitHub Actions. In fact, you can see the compilation and release process here (ignore the failure). This is a new process built by @LBPHacker that uses meson and GitHub to more easily compile and deliver updates. It is a large improvement over the release process we had before, as I don't have to maintain two separate build servers. Integrating this fully took a while, this is the main reason for 96.0's long delay. But it is all set now, and future releases can be done any time with the click of a few buttons.
    Along with this, Windows 64-bit support was added (see above), and Linux 32-bit support was dropped. 32-bit Linux had a low percentage of users. If there is demand, it could be added back, but this seems unlikely considering the amount of usage I see in the official game and mods that have 32-bit Linux versions. TPT is still easy to compile for 32-bit Linux for those who need it.

    Because several people have asked for it, I've created an informal beta of the Android version:

    This beta will be a separate installation from your normal app, so your saves and login won't transfer.

    There are no notable Android-specific changes in this update, besides a fix for a crash when scrolling in the options menu.

    Hey, I found a bug. The laser on the laser cannon I was using to blow up this thing for some reason would be invisible but would still blow it up. That would not always happen but it happened a lot. Ill show the screen shot. 

     EDIT: keeps saying post is too long ://

    You need to use an image or file upload site to share images, copy pasting the image into the textbox will copy the entire image contents into your message, which is why it says it's too long.

    Can you give a save ID showcasing the problem? If not, try a site like, or something like google drive / one drive to share your image.

    Hmm, can I also have a save ID? That save isn't published online.

    You can upload the save in the current stable release, or in the snapshots.

    Use the feedback section:

    Also even if you can't reproduce the issue, a save id may be helpful to me.
