# Snake Game on Metro RP2350
## Overview
The Metro RP2350 makes a perfect little game console. The on-board HSTX combined with a DVI breakout can output to a standard television or computer monitor for the display. The USB host connection makes it easy to take input from a keyboard to control the game.
The Adafruit Fruit Jam simplifies setup even further by having the DVI connector and USB Host connectors directly on the board without the need to solder or connect any ribbon cables or additional breakouts.
This game is an implementation of the [classic arcade game Snake](https://en.wikipedia.org/wiki/Snake_(video_game_genre)). The WASD keys on the keyboard control the snake by changing directions (up, left, right, down). The player's goal is to eat apples to score points. Each apple eaten grows the snake by an additional segment length.
You must avoid sending the snake out of the bounds of the display, and avoid wrapping around and hitting its own tail. This version provides a twist with both red and green apples. The red slow the snake down, and the green speed it up. With faster speeds come higher risk of a harder to control snake, and higher rewards in the form of more points awarded the faster the snake is moving.

# Snake Game on Metro RP2350
## Preparing the Metro RP2350
The USB Host port is the only part of this project that required soldering.
The USB Host pin connections are highlighted on the Metro image to the left. You will need a small piece of standard 0.1 inch male header, with 4 pins, to fit the holes.
You can cut header with diagonal cutters or break them with pliers or even your fingers. Just be sure to wear eye protection as they can fly when cut.
Put the short end of the header into the holes in the Metro marked USB Host and secure them with putty, blutack, tape, etc. Turn the Metro over and you should see the header barely poking out of the bottom of the board. If the pins stick through a great deal you may have the header pins upside down, double check the short end is sticking into the board.
Solder the 4 pin "nubbins" to the board.
Turn the board over and remove the material securing the pins. Now there is a new 4-pin header.
Get the USB Host cable and wire as follows:
**GRD** to **Black**
**D+** to **Green**
**D-** to **White**
**5V** to **Red**
## HSTX Connection to DVI
Get the HSTX cable. Any length Adafruit sells is fine. CAREFULLY lift the dark grey bar up on the Metro, insert the cable silver side down, blue side up, then put the bar CAREFULLY down, ensuring it locks. If it feels like it doesn't want to go, do not force it.
Do the same with the other end and the DVI breakout. Note that the DVI breakout will be inverted/upside down when compared to the Metro - this is normal for these boards and the Adafruit cables.
# Snake Game on Metro RP2350
## Install CircuitPython Metro
[CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** drive to iterate.
## CircuitPython Quickstart
Follow this step-by-step to quickly get CircuitPython running on your board.
[Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_metro_rp2350/)
**Click the link above to download the latest CircuitPython UF2 file.**
Save it wherever is convenient for you.
To enter the bootloader, hold down the **BOOT/**** BOOTSEL button**(highlighted in red above), and while continuing to hold it (don't let go!), press and release the**reset button**(highlighted in red or blue above). **Continue to hold the BOOT/BOOTSEL button until the RP2350 drive appears!**
If the drive does not appear, release all the buttons, and then repeat the process above.
You can also start with your board unplugged from USB, press and hold the BOOTSEL button (highlighted in red above), continue to hold it while plugging it into USB, and wait for the drive to appear before releasing the button.
A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.**
You will see a new disk drive appear called **RP2350**.
Drag the **adafruit-circuitpython-_boardname_-_language_-_version_.uf2** file to **RP2350.**
The **RP2350** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
That's it, you're done! :)
## Safe Mode
You want to edit your **code.py** or modify the files on your **CIRCUITPY** drive, but find that you can't. Perhaps your board has gotten into a state where **CIRCUITPY** is read-only. You may have turned off the **CIRCUITPY** drive altogether. Whatever the reason, safe mode can help.
Safe mode in CircuitPython does not run any user code on startup, and disables auto-reload. This means a few things. First, safe mode _bypasses any code in_ **boot.py** (where you can set **CIRCUITPY** read-only or turn it off completely). Second, _it does not run the code in_ **code.py**. And finally, _it does not automatically soft-reload when data is written to the_ **CIRCUITPY** _drive_.
Therefore, whatever you may have done to put your board in a non-interactive state, safe mode gives you the opportunity to correct it without losing all of the data on the **CIRCUITPY** drive.
### Entering Safe Mode
To enter safe mode when using CircuitPython, plug in your board or hit reset (highlighted in red above). Immediately after the board starts up or resets, it waits 1000ms. On some boards, the onboard status LED (highlighted in green above) will blink yellow during that time. If you press reset during that 1000ms, the board will start up in safe mode. It can be difficult to react to the yellow LED, so you may want to think of it simply as a slow double click of the reset button. (Remember, a fast double click of reset enters the bootloader.)
### In Safe Mode
If you successfully enter safe mode on CircuitPython, the LED will intermittently blink yellow three times.
If you connect to the serial console, you'll find the following message.
```terminal
Auto-reload is off.
Running in safe mode! Not running saved code.
CircuitPython is in safe mode because you pressed the reset button during boot. Press again to exit safe mode.
Press any key to enter the REPL. Use CTRL-D to reload.
```
You can now edit the contents of the **CIRCUITPY** drive. Remember, _your code will not run until you press the reset button, or unplug and plug in your board, to get out of safe mode._
## Flash Resetting UF2
If your board ever gets into a really _weird_ state and CIRCUITPY doesn't show up as a disk drive after installing CircuitPython, try loading this 'nuke' UF2 to RP2350. which will do a 'deep clean' on your Flash Memory. **You will lose all the files on the board** , but at least you'll be able to revive it! After loading this UF2, follow the steps above to re-install CircuitPython.

# Snake Game on Metro RP2350
## Code
## CircuitPython Usage
To use the game, you need to update **code.py** with the game program to the **CIRCUITPY** drive.
Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file.
Connect your board to your computer via a known good data+power USB cable. The board should show up in your File Explorer/Finder (depending on your operating system) as a flash drive named **CIRCUITPY**.
Extract the contents of the zip file, copy the **lib** directory files to **CIRCUITPY/lib**. Copy the **code.py** file to your **CIRCUITPY** drive. The program should self start.
## Drive Structure
After copying the files, your drive should look like the listing below. It can contain other files as well, but must contain these at a minimum.
## Code
The **code.py** for the project is shown below.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Metro/Metro_RP2350_Snake/code.py
# Snake Game on Metro RP2350
## Usage
Ensure a USB keyboard is plugged into the USB Host port wired up previously. Reset the board by cycling power or pressing the Reset button, if you happen to plug in a keyboard after power up.
Be sure you connect the DVI breakout to an HDMI monitor and the monitor is on. You might need a long cable if your monitor is not near the Metro RP2350 (like a television). The cables are standard and may be obtained from any trusted retail outlet. Also reset the Metro if you plug in HDMI after powering the Metro.
Once connections are all set, power the Metro RP2350 either via USB C (5 volts) or the barrel connection (5.5 to 17 volts DC, center positive).
## Gameplay
The default controls for the game are as follows:
- **any key: ** Press any key to start the game when the title screen is visible.
- **W** : Change the snakes direction to up.
- **A** : Change the snakes direction to left.
- **S** : Change the snakes direction to down.
- **D** : Change the snakes direction to right.
- **T** : Pause the game.
- **P** : After game over, press **P** to play again.
- **Q** : After game over, press **Q** to quit.
The controls for movement and pause can be reconfigured by simply changing the values in the `KEY_UP`, `KEY_LEFT`, `KEY_DOWN`, and `KEY_RIGHT` variables near the top of the **code.py** file.
The goal is to move the snake around the screen eating as many apples as you can. Eating a green apple will speed up the snakes movement making it quicker to get to the next apple, but at the cost of being harder to control once it starts moving faster. Eating a red apple slows the movement speed down.
Points are awarded to the player for each apple that is eaten, bonus points are given based on the length of the snake and the speed it's currently moving, the green apples also have a built-in extra bonus points compared to the red.
# Snake Game on Metro RP2350
## Code Explanation
The code for the game is thoroughly commented with explanations of what each line or section are for. This page will provide a higher level summary of the major components.
## Hardware Principals
This game is designed around two primary hardware peripherals: the HSTX connector with a DVI breakout for the display, and a basic USB keyboard for the player control input.
### HSTX Display
To initialize the display the built-in core modules `picodvi`, and `framebufferio` are used. These modules support a few different resolutions and color depths. This project is made for the 320x240 resolution with 16 bit color depth. The pixels are automatically doubled before being pushed to the display so it will come out as 640x480, depending on your monitor or TV, it may further upscale it to fit the screen.
### USB Keyboard
USB Host is relatively new to CircuitPython, first coming on Raspberry Pi RP2040-based boards.
Typically, one would access a USB port by:
- Establishing the USB connection
- Reading USB Reports, sections of bytes sent when an action occurs on the peripheral like a key is pressed or joystick moved.
- Parsing the reports and providing meaningful input to the program.
Python has the concept of standard input and output streams, similar to those in Linux/Unix and other operating systems. CircuitPython has this capability and through a lot of behind the scenes code, presents a USB keyboard as a stdin input device. The code to get USB Host Keyboard characters and echo them to serial out is as follows:
```auto
import supervisor
import sys
while True:
available = supervisor.runtime.serial_bytes_available
if available:
c = sys.stdin.read(available)
print(c, end='')
```
## Helper Classes
The game code has 4 helper classes which contain behavior for various parts of the game bundled together as easy to use component objects.
### `Snake`
The `Snake` class doesn't extend any other class and isn't responsible for any visual elements directly. It holds a list of x,y locations within the world grid for each segment of the snake's body, and the direction that the snake is currently moving in. It has a function to grow by one segment size. It also has some convenience functions to access the snake length, and the head and tail segments.
### `World`
The `World` class extends TileGrid and represents the playing field for this game. It handles all of the visual elements directly related to game play. It is responsible for:
- Spawning apples into the world.
- Drawing the snake by setting the appropriate sprite indexes for each snake segment.
- Moving the snake by updating the list of segment locations.
- Checking whether the snake has hit an edge or an apple.
### `SpeedAdjuster`
`SpeedAdjuster` is responsible for mapping a speed rating from `0`-`20` to a timing delay ranging from `0.05` to `0.4`. Smaller speed ratings map to lower delay times which in turn make the snake move faster. The delay time is how long the game will wait before rendering each from, so less delay means faster rendering and movement. `SpeedAdjuster` contains convenience functions for increasing and decreasing the speed by 1 unit, which are used when the two different colors of apples are eaten.
### `GameOverException`
This is a basic custom exception that will raise when the player loses by running into the edge of the world, or wrapping around and running the snake into itself. **code.py ** will catch this exception and show the game over message.
## code.py
The **code.py** script is based upon a [state machine](https://learn.adafruit.com/circuitpython-101-state-machines). There are 4 states that it can be in:
- Title - This is the state that the code begins in. It displays the title splash and the controls that are currently mapped. While this state is active, the code waits for any key to be pressed and when that occurs it changes the displays `root_group` to the `game_group` and changes the state to playing.
- Playing - The playing state is for active game play the snake moves around and the keyboard input is polled looking for the movement keys or the pause key. When movement keys are detected the direction of the snake is updated, when the pause key is pressed the state is changed to paused. If the snake runs into an edge or itself then the `GameOverException` is raised and the state is changed to gameover.
- Paused - During the `paused` state the main game loop does not run, instead the code just waits for keyboard input, and when the pause key is pressed the state is changed back to playing.
- Gameover - When the game has ended the game over message is updated to include the players score and then made visible on the screen. Keyboard input is polled, if the P key is pressed the game launches itself again, if the Q key is pressed then the code exits by breaking out of the main loop.
## Display Elements
The graphical elements are split into two main `Group`s. The `title_group` holds the title splash screen image and the instructions text that go beneath it. It's set as the root group when the code first runs to make it visible.
The `game_group` contains the `World` instance which is the `TileGrid` representing the game play area. It also holds the `score_txt` for the top bar, and the `game_over_label` which is made visible when the player loses. When the state is changed from title state to playing state the `root_group` of the display is updated to the `game_group`.
