Installing MPF on Windows

This process walks through installing MPF 0.57 a Windows machine.

Note that installing MPF is more complicated than a normal application. This is because MPF is a development tool you use to create your pinball software, not a finished app itself. So, like everything in pinball, there are a lot of steps.

Note

If you're an expert Python user, you can skip most of this page. Just know you need Python 3.9 (newer or older won't work, see below), and you can install MPF-MC via pip. pip install mpf-mc This will also install MPF. You probably also want to install MPF Monitor via pip install mpf-monitor.

Remove prior versions of MPF

MPF and the MPF-MC have many dependencies and requirements. If you have an older version of MPF installed, it may have installed some of these dependencies in a way that is incompatible with the latest version of MPF. So it's best to remove any prior versions of MPF before installing the latest version.

Uninstall MPF by using this command:

pip uninstall mpf

If you are unsure which version of MPF you have installed, you can run this command to check what is installed:

mpf --version

If you are using a virtual environment for MPF (recommended!) then you don't need to uninstall anything, just create a new one.

Windows System Requirements

MPF 0.57 requires Python 3.9, 3.10, or 3.11.

MPF can run on 3.8, but the MPF-MC audio doesn't work on Windows in those versions. So you should use Python 3.9.

Install Python

If you open a command prompt on a fresh Windows machine and type python, the Microsoft App Store will open and try to install Python 3.7. This is not the version of Python you want. So don't do that.

So instead, install Python from python.org. Here's the direct link to the newest installer for the final version of Python 3.9: https://www.python.org/ftp/python/3.9.13/python-3.9.13-amd64.exe

Run the installer, and choose the "Customize installation" option, and make sure to check the box for "py launcher" and "pip". (The others don't matter either way.) Then on the next screen, check the box for "Add Python to environment variables". Then click "Install".

Then open a command prompt (you can just run "cmd"), and type each of these commands one at a time (and hit enter after each one). First, make sure Python is installed and make sure when you run "python" that it's the proper version. (Sometimes Windows will have multiple versions of Python installed and it's not always clear which one will be used when you type "python".)

python --version

You want a result like "Python 3.9.13" or whatever version you just installed. If you see a version other than that, trying running python3 --version instead.

Create a Virtual Environment

It's strongly recommended to create a virtual environment for MPF, which will keep the installed packages from conflicting with other applications on your computer. Before proceeding, follow the steps on the virtual environment installation guide

Install MPF

Now you're ready to install MPF. Open a new command window (cmd.exe), activate your virtual environment, and type these commands and hit enter.

pip install "mpf"

A bunch of things will scroll by, and then hopefully MPF is installed. You can test it by typing this command:

mpf --version

This should print out something like MPF 0.57.0. If you get an error, something went wrong. If you get a different version, then you might have an older version of MPF which you need to uninstall first. (See the "Remove prior versions of MPF" section above.)

Install MPF Monitor

MPF Monitor the developers "god view" into your running MPF code. It has windows to show the states of every device, events, variables, modes, etc. You can even add a photo of your playfield and it will show all the lights and switches on it animated in real time to show you what's happening in your game.

MPF Monitor is also nice because it's a simple install, so you can visualize your game quickly. The MPF-MC (which will drive the displays in your machine) is a more complicated install, so you can get your game working with MPF Monitor first, and then add the MPF-MC later.

pip install mpf-monitor

You can now proceed with the getting started tutorials, or, go on to install the MPF Media Controller (MPF-MC).

Install the MPF Media Controller (MPF-MC)

The MPF Media Controller (MPF-MC) is a standalone package used to control the graphics, sounds, and music in a pinball machine. It's a separate package from MPF. Not every pinball machine uses MPF-MC, but most do. (There are also other media controllers that are not MPF-MC. For example, some people use Unity, the Unreal Engine, or Godot as their media controllers.)

To install MPF-MC, open your virtual environment and use the following command:

pip install mpf-mc

If you encounter permission issues during the installation, try running the commands with administrator privileges (Right-click on cmd.exe -> Run as Administrator).

Testing MPF-MC

Installing MPF-MC is pretty straightforward. Unfortunately just because it installs doesn't mean it works. :(

Dec. 2023 Note: mc_demo and demo_man aren't working, but you can get the demo_man loading screen to display after performing the following:

Because 0.57 is the current release, download the 0.57.x branch of the mpf-examples repo from here: https://github.com/missionpinball/mpf-examples.

You can download the zip file and unzip it, or clone it. If you download the dev branch, you will have config version mismatch issues.

From the commmand terminal, change to the mpf-examples-0.57.x directory, where ever it was downloaded. Then, change to the demo_man directory. Finally, run the following command:

mpf mc

You should have text displayed in the terminal, showing that MPF MC is loading, then the MPF BCP server should wait for a connection:

The Demo Man loading screen should also be displayed:

May 2023 Note: Some of this might not work: The mc_demo and demo_man mentioned below might not work anymore as they haven't been updated in a while. Feel free to fix and/or update them and we'll merge your changes in!

One way to test the MC is download the mpf-examples repo from here: https://github.com/missionpinball/mpf-examples. You can either clone it locally, or download the zip file and unzip it. Either is fine, just do what you're most comfortable with. Be sure to download / switch to the dev branch.

Then back in the command terminal, change into the mpf-examples folder (or whatever folder you just unzipped that into), then change into the mc_demo folder, then run mpf both. That should launch the mc_demo code (which is Media Controller demo). A window should open with a red background and some text about slides, you should be able to use the right arrow key to advance to the next slide. You should be able to use the left arrow key to go back to the previous slide and you should hear a drum and cymbal sound when you change the slide.

You will see a bunch of warnings about some classes implemented in multiple locations, and how one will be used, but which one is undefined. It sounds scary, but this is normal. (For now.) We are investigating whether this is something we need to fix, and how we'll fix it if so. But for now it's fine.

You can also run the "demo_man" game from the mpf-examples folder. Change into the demo_man folder and run mpf both -X. You should see the DMD window pop up. The window you ran the command from will have some warnings which cover up the nice text UI display. Just grab a corner of the window with the mouse and resize the window (just make it a tiny bit bigger and smaller) and that will cause the window contents to completely refresh and you should see the expected MPF text UI display showing switch status, ball locations, etc. (See the screenshots below for details)

If you do not see the "normal" MPF text UI display, and instead see something like this:

This is because those warnings mentioned above print on top of the nice MPF display. To fix this, just grab a corner of the window with the mouse and resize it to be a bit bigger or smaller, which will cause the entire window to update and you should see the expected MPF text UI display showing switch status, ball locations, etc. (See the screenshots below for details)

Alternately if you don't want to resize the window every time, you can open two different command prompt windows, and run mpf -X in one and mpf mc in the other.

At this point, MPF is ready to go!

Keeping MPF up-to-date

Once you have MPF installed via the procedure above, you can keep it up-to-date by running the final two pip commands from above which you used to install MPF and MPF-MC.
