  • How do I use Powder Toy behind a proxy?
    You can use the Powder Toy behind a proxy by specifying it at the command line, On Windows and Linux, this is simply a case of issuing the command
    'powder proxy:{address}:{port}' where {address} is the address of the proxy and {port} is the port.
    On a Mac, this is a bit more complicated, you must open a terminal and go to the directory with Powder.app in, and issue the command

    An example command would be
    'powder.exe proxy:wwwcache.school.ac.uk:3128'

  • When I try to login, I get a '605 - Timeout' error. How do I fix this?
    This error is very general. It means that the Powder Toy cannot communicate with the server, usually because there is no internet connection, or the port used has been intentionally blocked by an administrator. If you're trying to use the Powder Toy from within a corporate or school network, it is likely you'll need to use a proxy. Another known cause is Firewall or internet filtering software that runs on the computer, if this is the case, the relevant proxy settings need to be acquired, or the software disabled.
  • I've registered on the website, but I cannot login.
    Your password is case-sensitive, make sure you are using the correct casing. Another possible issue is your password may have characters that you cannot correctly enter into the Powder Toy, in which case, you should change your password on the website in your profile. Another rare but possible issue is that the username or password is too long to be entered in the game login screen. If you still can't login, you may request a password reset here: https://powdertoy.co.uk/PasswordReset.html

  • Can we have movable solids?
    No. That will require too much work, because it's hard to make particle-solid collisions.
  • Will be there a 3D powder toy?
    No. 3D powder toy can be imagined as many usual TPT windows stacked in one. FPS of that "stack" will be really small.

  • What is ambient heat?/Can we have hot and cold air?
    Ambient heat is a mode where air has temperature. It can be cooled or heated, which makes air simulation more realistic. Turn it on by clicking the A button on the top right corner of the screen.
  • What is TPT++? Does it have new elements?
    TPT was originally written in C, but in 2012 it was rewritten in C++ to make development easier. The version you use today is TPT++, but the terminology is mostly lost to the ages.
  • How can I translate TPT to another language?
    Translation support does not yet exist in the game. Also, some languages require special font characters to be drawn. TPT's font includes several extentions such as latin-1 and Cyrillic, but translation support hasn't arrived yet.
  • How can I add new elements to TPT?
    There are several ways. You can learn Lua (a scripting language used in TPT), and add new elements with scripts (check wiki).
    Another way is, read the development tutorial on the wiki and compile TPT yourself.
