pyxel play 30sec_of_daylight.pyxapp ``` ## How to Use ### Create Application In your Python script, import the Pyxel module, specify the window size with the `init` function, and then start the Pyxel application with the `run` function. ```python import pyxel pyxel.init(160, 120) def update(): if pyxel.btnp(pyxel.KEY_Q): pyxel.quit() def draw(): pyxel.cls(0) pyxel.rect(10, 10, 20, 20, 11) pyxel.run(update, draw) ``` The arguments of the `run` function are the `update` function, which processes frame updates, and the `draw` function, which handles screen drawing. In an actual application, it is recommended to wrap Pyxel code in a class, as shown below: ```python import pyxel class App: def __init__(self): pyxel.init(160, 120) self.x = 0 pyxel.run(self.update, self.draw) def update(self): self.x = (self.x + 1) % pyxel.width def draw(self): pyxel.cls(0) pyxel.rect(self.x, 0, 8, 8, 9) App() ``` For creating simple graphics without animation, you can use the `show` function to simplify your code. ```python import pyxel pyxel.init(120, 120) pyxel.cls(1) pyxel.circb(60, 60, 40, 7) pyxel.show() ``` ### Run Application A created script can be executed using the `python` command: ```sh python PYTHON_SCRIPT_FILE ``` It can also be run with the `pyxel run` command: ```sh pyxel run PYTHON_SCRIPT_FILE ``` Additionally, the `pyxel watch` command monitors changes in a specified directory and automatically re-runs the program when changes are detected: ```sh pyxel watch WATCH_DIR PYTHON_SCRIPT_FILE ``` Directory monitoring can be stopped by pressing `Ctrl(Command)+C`. ### Special Key Controls The following special key actions are available while a Pyxel application is running: - `Esc`<br> Quit the application - `Alt(Option)+1`<br> Save the screenshot to the desktop - `Alt(Option)+2`<br> Reset the recording start time of the screen capture video - `Alt(Option)+3`<br> Save a screen capture video to the desktop (up to 10 seconds) - `Alt(Option)+8` or `A+B+X+Y+DL` on gamepad<br> Toggles screen scaling between maximum and integer - `Alt(Option)+9` or `A+B+X+Y+DR` on gamepad<br> Switch between screen modes (Crisp/Smooth/Retro) - `Alt(Option)+0` or `A+B+X+Y+DU` on gamepad<br> Toggle the performance monitor (fps/`update` time/`draw` time) - `Alt(Option)+Enter` or `A+B+X+Y+DD` on gamepad<br> Toggle fullscreen - `Shift+Alt(Option)+1/2/3`<br> Save image bank 0, 1, or 2 to the desktop - `Shift+Alt(Option)+0`<br> Save the current color palette to the desktop ### How to Create Resources Pyxel Editor can create images and sounds used in a Pyxel application. You can start Pyxel Editor with the following command: ```sh pyxel edit PYXEL_RESOURCE_FILE ``` If the specified Pyxel resource file (.pyxres) exists, it will be loaded. If it does not exist, a new file with the specified name will be created. If the resource file is omitted, a new file named `my_resource.pyxres` will be created. After starting Pyxel Editor, you can switch to another resource file by dragging and dropping it onto Pyxel Editor. The created resource file can be loaded using the `load` function. Pyxel Editor has the following editing modes. **Image Editor** The mode for editing the image in each **image bank**. <a href="https://kitao.github.io/pyxel/wasm/examples/image_editor.html"> <img src="docs/images/image_editor.gif"> </a> You can drag and drop an image file (PNG/GIF/JPEG) into the image editor to load the image into the currently selected image bank. **Tilemap Editor** The mode for editing **tilemaps** that arrange images from the image banks in a tile pattern. <a href="https://kitao.github.io/pyxel/wasm/examples/tilemap_editor.html"> <img src="docs/images/tilemap_editor.gif"> </a> Drag and drop a TMX file (Tiled Map File) onto the tilemap editor to load its layer 0 into the currently selected tilemap. **Sound Editor** The mode for editing **sounds** used for melodies and sound effects. <a href="https://kitao.github.io/pyxel/wasm/examples/sound_editor.html"> <img src="docs/images/sound_editor.gif"> </a> **Music Editor** The mode for editing **musics** in which the sounds are arranged in order of playback. <a href="https://kitao.github.io/pyxel/wasm/examples/music_editor.html"> <img src="docs/images/music_editor.gif"> </a> ### Other Resource Creation Methods Pyxel images and tilemaps can also be created using the following methods: - Create an image from a list of strings using the `Image.set` function or the `Tilemap.set` function - Load an image file (PNG/GIF/JPEG) in Pyxel palette with `Image.load` function Pyxel sounds can also be created using the following method: - Create a sound from strings with `Sound.set` function or `Music.set` function Refer to the API reference for the usage of these functions. ### How to Distribute Applications Pyxel supports a dedicated application distribution file format (Pyxel application file) that is cross-platform. A Pyxel application file (.pyxapp) is created using the `pyxel package` command: ```sh pyxel package APP_DIR STARTUP_SCRIPT_FILE ``` If you need to include resources or additional modules, place them in the application directory. Metadata can be displayed at runtime by specifying it in the following format within the startup script. Fields other than `title` and `author` are optional. ```python # title: Pyxel Platformer # author: Takashi Kitao # desc: A Pyxel platformer example # site: https://github.com/kitao/pyxel # license: MIT # version: 1.0 ``` The created application file can be run using the `pyxel play` command: ```sh pyxel play PYXEL_APP_FILE ``` A Pyxel application file can also be converted to an executable or an HTML file using the `pyxel app2exe` or `pyxel app2html` commands. ## API Reference ### System - `width`, `height`<br> The width and height of the screen - `frame_count`<br> The number of the elapsed frames - `init(width, height, [title], [fps], [quit_key], [display_scale], [capture_scale], [capture_sec])`<br> Initialize the Pyxel application with the screen size (`width`, `height`). The following options can be specified: the window title with `title`, the frame rate with `fps`, the key to quit the application with `quit_key`, the display scale with `display_scale`, the screen capture scale with `capture_scale`, and the maximum recording time of the screen capture video with `capture_sec`.<br> Example: `pyxel.init(160, 120, title="My Pyxel App", fps=60, quit_key=pyxel.KEY_NONE, capture_scale=3, capture_sec=0)` - `run(update, draw)`<br> Start the Pyxel application and call the `update` function for frame update and the `draw` function for drawing. - `show()`<br> Show the screen and wait until the `Esc` key is pressed. - `flip()`<br> Refresh the screen by one frame. The application exits when the `Esc` key is pressed. This function is not available in the web version. - `quit()`<br> Quit the Pyxel application. ### Resource - `load(filename, [excl_images], [excl_tilemaps], [excl_sounds], [excl_musics])`<br> Load the resource file (.pyxres). If an option is set to `True`, the corresponding resource will be excluded from loading. If a palette file (.pyxpal) with the same name exists in the same location as the resource file, the palette display colors will also be updated. The palette file contains hexadecimal entries for the display colors (e.g. `1100FF`), separated by newlines. The palette file can also be used to change the colors displayed in Pyxel Editor. - `user_data_dir(vendor_name, app_name)`<br> Returns the user data directory created based on `vendor_name` and `app_name`. If the directory does not exist, it will be created automatically. It is used to store high scores, game progress, and similar data.<br> Example: `print(pyxel.user_data_dir("Takashi Kitao", "Pyxel Shooter"))` ### Input - `mouse_x`, `mouse_y`<br> The current position of the mouse cursor - `mouse_wheel`<br> The current value of the mouse wheel - `btn(key)`<br> Return `True` if the `key` is pressed, otherwise return `False`. ([Key definition list](python/pyxel/__init__.pyi)) - `btnp(key, [hold], [repeat])`<br> Return `True` if the `key` is pressed in that frame, otherwise return `False`. If `hold` and `repeat` are specified, after the `key` has been held down for `hold` frames or more, `True` is returned every `repeat` frames. - `btnr(key)`<br> Return `True` if the `key` is released in that frame, otherwise return `False`. - `mouse(visible)`<br> Show the mouse cursor if `visible` is `True`, and hide it if `visible` is `False`. The cursor's position continues to update even when it is hidden. ### Graphics - `colors`<br> List of the palette display colors. The display color is specified by a 24-bit numerical value. Use `colors.from_list` and `colors.to_list` to directly assign and retrieve Python lists.<br> Example: `old_colors = pyxel.colors.to_list(); pyxel.colors.from_list([0x111111, 0x222222, 0x333333]); pyxel.colors[15] = 0x112233` - `images`<br> List of the image banks (instances of the Image class) (0-2)<br> Example: `pyxel.images[0].load(0, 0, "title.png")` - `tilemaps`<br> List of the tilemaps (instances of the Tilemap class) (0-7) - `clip(x, y, w, h)`<br> Set the drawing area of the screen from (`x`, `y`) with a width of `w` and a height of `h`. Call `clip()` to reset the drawing area to full screen. - `camera(x, y)`<br> Change the upper-left corner coordinates of the screen to (`x`, `y`). Call `camera()` to reset the upper-left corner coordinates to (`0`, `0`). - `pal(col1, col2)`<br> Replace color `col1` with `col2` when drawing. Call `pal()` to reset to the initial palette. - `dither(alpha)`<br> Apply dithering (pseudo-transparency) when drawing.

If a negative value is assigned to `w` and/or `h`, the region will be flipped horizontally and/or vertically. If `colkey` is specified, it will be treated as a transparent color. If `rotate`(in degrees), `scale`(1.0 = 100%), or both are specified, the corresponding transformations will be applied. <img src="docs/images/blt_figure.png"> - `bltm(x, y, tm, u, v, w, h, [colkey], [rotate], [scale])`<br> Copy the region of size (`w`, `h`) from (`u`, `v`) of the tilemap `tm`(0-7) to (`x`, `y`). If a negative value is assigned to `w` and/or `h`, the region will be flipped horizontally and/or vertically. If `colkey` is specified, it will be treated as a transparent color. If `rotate`(in degrees), `scale`(1.0 = 100%), or both are specified, the corresponding transformations will be applied. The size of a tile is 8x8 pixels and is stored in a tilemap as a tuple of `(image_tx, image_ty)`. <img src="docs/images/bltm_figure.png"> - `text(x, y, s, col)`<br> Draw a string `s` in color `col` at (`x`, `y`). ### Audio - `sounds`<br> List of the sounds (instances of the Sound class) (0-63)<br> Example: `pyxel.sounds[0].speed = 60` - `musics`<br> List of the musics (instances of the Music class) (0-7) - `play(ch, snd, [tick], [loop], [resume])`<br> Play the sound `snd`(0-63) on channel `ch`(0-3).

To resume the previous sound after playback ends, set `resume` to `True`. - `playm(msc, [tick], [loop])`<br> Play the music `msc`(0-7). The playback start position can be specified by `tick`(1 tick = 1/120 seconds). If `loop` is set to `True`, loop playback is performed. - `stop([ch])`<br> Stop playback of the specified channel `ch`(0-3). Call `stop()` to stop all channels. - `play_pos(ch)`<br> Get the sound playback position of channel `ch`(0-3) as a tuple of `(sound_no, note_no)`.

Rest notes are represented by `-1`. - `tones`<br> List of tones (0:Triangle / 1:Square / 2:Pulse / 3:Noise) - `volumes`<br> List of volumes (0-7) - `effects`<br> List of effects (0:None / 1:Slide / 2:Vibrato / 3:FadeOut / 4:Half-FadeOut / 5:Quarter-FadeOut) - `speed`<br> Playback speed. `1` is the fastest, and the larger the number, the slower the playback speed. At `120`, the length of one note becomes 1 second. - `set(notes, tones, volumes, effects, speed)`<br> Set notes, tones, volumes, and effects using a string. If the length of tones, volumes, or effects are shorter than the notes, they will be repeated from the beginning. - `set_notes(notes)`<br> Set the notes using a string made of 'CDEFGAB'+'#-'+'01234' or 'R'. It is case-insensitive, and whitespace is ignored.<br> Example: `pyxel.sounds[0].set_notes("G2B-2D3R RF3F3F3")` - `set_tones(tones)`<br> Set the tones with a string made of 'TSPN'. Case-insensitive and whitespace is ignored.<br> Example: `pyxel.sounds[0].set_tones("TTSS PPPN")` - `set_volumes(volumes)`<br> Set the volumes with a string made of '01234567'. Case-insensitive and whitespace is ignored.<br> Example: `pyxel.sounds[0].set_volumes("7777 7531")` - `set_effects(effects)`<br> Set the effects with a string made of 'NSVFHQ'. Case-insensitive and whitespace is ignored.<br> Example: `pyxel.sounds[0].set_effects("NFNF NVVS")` ### Music Class - `seqs`<br> A two-dimensional list of sounds (0-63) across multiple channels - `set(seq0, seq1, seq2, ...)`<br> Set the lists of sound (0-63) for each channel. If an empty list is specified, that channel will not be used for playback.<br> Example: `pyxel.musics[0].set([0, 1], [], [3])` ### Advanced API Pyxel includes an "Advanced API" that is not mentioned in this reference, as it may confuse users or require specialized knowledge to use.
