The Powder Toy에서는 자신이 모드를 직접 만들 수 있으며 그 것을 모드 포럼에 배포할 수도 있습니다. 이 문서에서는 The Powder Toy에서 모드를 코딩하기 위한 방법을 보여줍니다. 이 문서의 내용 외에 추가적인 질문이 있다면 이 곳에서 확인할 수 있습니다.

EDITOR NOTE: Please do not edit this guide without consulting with TPT developers first; you risk your changes being mercilessly rolled back without prior notice otherwise.

Using the Visual Studio IDE

The method above does not let you use the 'Visual' part of Visual Studio, the IDE. Although Meson has limited support for this use case, if for some reason you wish to use the IDE, you can ask Meson to generate a build site that uses Visual Studio instead of Ninja.

• open a VS prompt (see above) and execute the following commands

cd /d [wherever you keep your repositories]
cd The-Powder-Toy
meson --backend=vs -Dbackend_startup_project=powder build-debug-vs

• you will not need the VS dev prompt beyond this point

This will generate a build site with a Visual Studio solution inside (the-powder-toy.sln). You can use this as any other solution, except for a few key differences:

• the IDE can only be used for more comfortable editing and debugging and not much else, including changing the project structure; you will have to familiarise yourself with Meson and work with the meson.build files in order to do that
• once you actually change meson.build files, Meson will automatically regenerate the solution the next time you try to build it; Visual Studio will give you a scary popup about the solution having been changed, which is perfectly normal, just click 'Reload Solution'
• the configuration you currently see (most likely debug|x64, if you are following this guide exactly) is the only configuration the solution has, and it is not recommended to add other configurations as Meson will just overwrite them the next time it regenerates the solution; instead, you have to generate separate build sites with Meson

Next steps (all platforms)

Updating the binary

Now that you have successfully built TPT for the first time, you will probably want to change things in the code. To update the binary, build it again by executing

ninja

in the same prompt you executed it the last time. You will have to do this every time you change something and want the binary to reflect the change.

Release builds

So far, you have been building "debug" binaries. These make debugging significantly easier than "release" builds, but they also offer less performance. You can instead build a "release" binary, which is much more performant, but very difficult to debug. Only use these builds when you are certain that you have no more bugs to take care of. If a bug does appear later on, go back to building debug binaries.

To build a release binary, navigate back to the root of the repository in your prompt and create a new build site with Meson, then build with Ninja again

cd /d [wherever you keep your repositories]
cd The-Powder-Toy
meson -Dbuildtype=release build-release
cd build-release
ninja

Note that build-debug and build-release directories are independent "build sites", each of which you can update with Ninja when you set them as your current directory (by using cd, see the lists of commands above).

Static builds

Both the debug and release configurations above produce "dynamic" binaries, which means they depend on certain components of your system (libraries you have installed with apt on linux or with brew on macos) or files other than powder.exe (DLLs in the same directory as powder.exe on windows). If you are a mod author, please make sure you are not shipping such binaries, as your users are used to TPT not depending on anything and thus are unlikely to have experience with installing these libraries on their own.

You can get rid of most of these dependencies by building a "static" binary. This way, the binary will depend on very basic components of your system that are very likely to be present. It will also gain a few megabytes and linking it will take longer, which is why you would only do this when you are about to release it to the public.

To build a static binary, navigate back to the root of the repository in your prompt and create a new build site with Meson (see NOTE below!), then build with Ninja again

meson -Dbuildtype=release -Dstatic=prebuilt build-release-static
cd build-release-static
ninja

NOTE: On Windows, you will also need to add the -Db_vscrt=static_from_buildtype option to the Meson call above, otherwise the resulting binaries will be dynamically linked against the MSVC runtime (vcruntime.dll and similar).

meson -Dbuildtype=release -Dstatic=prebuilt -Db_vscrt=static_from_buildtype build-release-static
cd build-release-static
ninja

It used to work, but it broke

Each platform has its own set of quirks that need to be worked around (mostly looking at you, microsoft and apple). Fortunately, our build system takes care of most of these. Unfortunately, the workarounds come in the form of upgrades to the build system, which are not installed automatically, and even if they are, affected build sites may need to be reconfigured manually. If you had at some point gotten TPT to build successfully, but since then your build sites somehow broke, you can try one of the following methods to fix them.

The most straightforward way to fix a single build site is to reconfigure it. To check if this worked, try running Ninja.

cd /d [wherever you keep your repositories]
cd The-Powder-Toy
meson --reconfigure --wipe build-debug # or whatever you named your build site
ninja

You will have to do this with every broken build site.

If this does not help, you can upgrade pip, Meson and Ninja. Like when setting them up for the first time, add sudo -H on linux and macos, and run this in an elevated command prompt on windows.

python -m pip install --upgrade pip # if you get "No module named pip", try python3
pip install --upgrade meson ninja

Once you are done with this, reconfigure your build sites (see above).

If not even this helps, that is your cue to start from scratch, following the guide as if you are building TPT for the first time, except you already have the repository, so you do not need to clone that again. In fact, this is where your changes to TPT are stored, so you should never delete it. Deleting your local clone of the repository never solves any problem, it only results in loss of code. Do not even consider doing it.

As a last resort, you can ask us on the forum.

빌드 옵션

Build options are passed to Meson at when you set up a build site (see examples above) or at any later time, when the build site is already in use. In both cases, they are passed as command line arguments of the form -D[name]=[value]. For example, to set up a build site that compiles TPT with Lua 5.1 instead of LuaJIT, you would issue the following command

meson -Dlua=lua5.1 build-debug-lua5.1

But you could also take an existing build site and change the relevant build option to do the same

cd build-debug
meson configure -Dlua=lua5.1

The next time you run Ninja, everything that needs to be rebuilt as a result of this change will be rebuilt. See the Meson quick guide for more on configuring build sites.
