The compressed size limit is not enforced for saving in. It is possible to edit. The file differs in content from the last loaded version. PICO-8 reads configuration settings from config. To find out the id of your controller as it is detected by SDL2, search for "joysticks" or "Mapping" in log.
This id may vary under different operating systems. You can save a video at any time it is always recording ; CTRL-8 simply resets the video starting point. If you have trouble saving to the desktop, try configuring an alternative desktop path in config. While inside a cart, press MENU to favourite a cartridge or exit to splore.
If you're using a keyboard, it's also possible to press F to favourite an item while it is selected in the cartridge list view. When viewing a list of BBS carts, use the top list item to re-download a list of cartridges. If you are offline, the last downloaded list is displayed, and it is still possible to play any cartridges you have downloaded.
Press ESC to toggle between console and editor. The number of code tokens is shown at the bottom right. One program can have a maximum of tokens. Each token is a word e. Pairs of brackets, and strings each count as 1 token. Right click to toggle through other stats character count, compressed size. If a limit is reached, a warning light will flash. This can be disabled by right-clicking. The sprite editor is designed to be used both for sprite-wise editing and for freeform pixel-level editing.
The sprite navigator at the bottom of the screen provides an 8x8 sprite-wise view into the sprite sheet, but it is possible to use freeform tools pan, select when dealing with larger or oddly sized areas.
Click to stamp whatever is in the copy buffer. Hold CTRL to treat colour 0 black as transparent. Click and drag to create a rectangular selection. If a pixel-wise selection is not present, many operations are instead applied to a sprite-wise selection, or the visible view. To select sprites, shift-drag in the sprite navigator. Fill with the current colour.
This applies only to the current selection, or the visible area if there is no selection. Hold CTRL to get a filled oval or rectangle. F: Flip sprite horizontally V: Flip sprite vertically R: Rotate requires a square selection Cursor keys to shift loops if sprite selection. The 8 coloured circles are sprite flags for the current sprite. They are indexed from 0 starting from the left. In both cases, the image is colour-fitted to the current display palette.
The PICO-8 map is a x32 or x64 using shared space block of 8-bit values. Each value is shown in the editor as a reference to a sprite It's up to you how you use the data, but be aware that drawing on the second half of the sprite sheet could clobber data on the map and vice versa. The tools are similar to the ones used in sprite editing mode.
Select a sprite and click and drag to paint values into the map. Select the sprites you would like to move while still in map view , and press Ctrl-X 3. Select the destination sprite also while still in map view and press Ctrl-V. C5 An instrument A play speed SPD : the number of 'ticks' to play each note for.
When only the first of the 2 numbers is used and the second one is 0 , it is taken to mean the number of notes to be played. This is normally not needed for sound effects you can just leave the remaining notes empty , but is useful for controlling music playback.
The mode can be changed using the top-left buttons, or toggled with TAB. Click and drag on the pitch area to set the frequency for each note, using the currently selected instrument indicated by colour. Hold shift to apply only the selected instrument. Right click to grab the instrument of that note. Each note shows: frequency octave instrument volume effect To enter a note, use q2w3er5t6y7ui zsxdcvgbhnjm piano-like layout Hold shift when entering a note to transpose -1 octave..
Note that only the selected attributes are copied. Double-click to select all attributes of a single note. Music in PICO-8 is controlled by a sequence of 'patterns'. Each pattern is a list of 4 numbers indicating which SFX will be played on that channel. When a pattern has SFXes with different speeds, the pattern finishes playing when the left-most non-looping channel has finished playing.
This can be used to set up double-time drum beats or unusual polyrhythms. To select a range of patterns: click once on the first pattern in the pattern navigator, then shift-click on the last pattern. When pasting into another cartridge, the SFX that each pattern points to will also be pasted possibly with a different index if it does not already exist.
In addition to the 8 built-in instruments, custom instruments can be defined using the first 8 SFX. Use the toggle button to the right of the instruments to select an index, which will show up in the instrument channel as green instead of pink.
For example, a simple tremolo effect could be implemented by defining an instrument in SFX 0 that rapidly alternates between volume 5 and 2. In this way, SFX instruments can be used to control combinations of detailed changes in volume, pitch and texture.
SFX instruments are only retriggered when the pitch changes, or the previous note has zero volume. This is useful for instruments that change more slowly over time. For example: a bell that gradually fades out. To invert this behaviour, effect 3 normally 'drop' can be used when triggering the note. All other effect values have their usual meaning when triggering SFX instruments. The EXPORT command can be used to generate png, wav files and stand-alone html and native binary cartridge applications.
The output format is inferred from the filename extension e. You are free to distribute and use exported cartridges and data as you please, provided that you have permission from the cartridge author and contributors. This can be useful for example, to save a copy in.
For example, from a Linux shell:. When exported as. For most purposes, the default. By default, the cartridge label is used as an icon with no transparency. Size 3 would be produce a 24x24 icon. Use 16 for no transparency. For example, to use a 2x2 sprite starting at index 32 in the sprite sheet, using colour 12 as transparent:.
Windows file systems do not support the file metadata needed to create a Linux or Mac executable. PICO-8 works around this by exporting zip files in a way that preserves the file attributes. It is therefore recommended that you distribute the outputted zip files as-is to ensure users on other operating systems can run them. HTML 2. Create a new project from your itch dashboard. Zip up the folder and upload it set "This file will be played in the browser" 4.
Embed in page, with a size of px x px. Set "Mobile Friendly" on default orientation and "Automatically start on page load" on. Set the background BG2 to something dark e. Up to 16 cartridges can be bundled together by passing them to EXPORT, when generating stand-alone html or native binary players.
Exported cartridges are unable to load and run BBS cartridges e. Use the -export switch when launching PICO-8 to run the exporter in headless mode. File paths are relative to the current directory rather than the PICO-8 file system. The following is a brief summary of essential Lua syntax. Numbers written in decimal are rounded to the closest fixed point value.
TOSTR In Lua, tables are a collection of key-value pairs where the key and value types can both be mixed. They can be used as arrays by indexing them with integers. Tables with 1-based integer indexes are special though. Shorthand assignment operators can also be used if the whole statement is on one line.
PRINT 1! When a PICO-8 programs runs, all of the code from tabs is concatenated from left to right and executed. It is possible to provide your own main loop manually, but typically PICO-8 programs use 3 special functions that, if defined by the author, are called during program execution:.
Note that not all host machines are capable of running at 60fps. When the cartridge is run, the contents of each included file is treated as if it had been pasted into the editor in place of that line. When a cartridge is saved as. PNG, or exported to a binary, any included files are flattened and saved with the cartridge so that there are no external dependencies. Built-in operations like drawing sprites also have a CPU cost.
Instead, a small api is offered in keeping with PICO-8's minimal design and limited screen space. Note that PICO-8 does not have upper or lower case characters -- if you are editing a.
System functions called from commandline can omit the usual brackets and string quotes. P8" , it is possible to write:. Filenames that start with ' ' are taken to be a BBS cart id, that is immediately downloaded and run:. If the id is the cart's parent post, or a revision number is not specified, then the latest version is fetched.
List files in the current directory. When called from a running program, returns a list of all. Use a single ". This enters frame-by-frame mode, that can be read with stat While frame-by-frame mode is active, entering an empty command by pressing enter advances one frames.
Reset the values in RAM from 0x5f This includes the palette, camera position, clipping and fill pattern. If you get lost at the command prompt because the draw state makes viewing text impossible, try typing RESET! It can also be called from a running program.
Flip the back buffer to screen and wait for next frame. But when using a custom main loop, a call to FLIP is normally needed:.
If filename is set, append the string to a file on the host operating system in the current directory by default -- use FOLDER to view. Use stat 4 to read the clipboard, but the contents of the clipboard are only available after pressing CTRL-V during runtime for security. Audio values Due to the nature of the gif format, all gifs are recorded at To record exactly one frame each time FLIP is called, regardless of the runtime framerate or how long it took to generate the frame, use:.
PICO-8 has a fixed capacity of 8x8 sprites, plus another that overlap with the bottom half of the map data "shared data". These sprites are collectively called the sprite sheet, and can be thought of as a x pixel image. All of PICO-8's drawing operations are subject to the current draw state. The draw state includes a camera position for adding an offset to all coordinates , palette mapping for recolouring sprites , clipping rectangle, a drawing colour, and a fill pattern.
The initial state of flags It is also possible to draw only a subset of map tiles by providing a mask in MAP.
When X, Y are not specified, a newline is automatically appended. This can be omitted by ending the string with an explicit termination control character:. Additionally, when X, Y are not specified, printing text below causes the console to scroll. This can be disabled during runtime with POKE 0x5f36,0x PRINT returns the right-most x position that occurred while printing. Scheda tecnica PicoScope serie PicoScope and Data Sheet.
