PICO-8 0.2.0 !

Ça y est : le PICO nouveau (0.2.0) est sorti. J’ai dû faire un gros effort sur le titre pour le pas ajouter une vingtaine de points d’exclamations. Pour être honnête, après le 5e, je me suis dit que cela ne faisait pas très sérieux : j’en ai donc retiré 4.


Les nouveautés les plus visibles sont l’arrivés de 16 onglets, de la possibilité d’afficher les tabulations (aide à aligner le code), l’ajout de deux polices de caractères supplémentaires :  Puny  (minuscule latine => [ctrl]-[p]) et Katanaka (japonais => [ctrl]-[k]).

Les nouvelles fonction ord() et chr() permettent respectivement  de récupérer le code ASCII d’un caractère et le caractère d’un code ASCII, exemple :

Affiche : 97, 128, 65, 204. A noter que le ‘A’ classque correspond au ‘A’ en minuscule (de la table ASCII) et le ‘A’ pony (3e) au ‘A’ majuscule (malgré leur aspect respectif à l’écran).

La nouvelle  instruction   tline permet  de dessiner des lignes texturées à l’écran.  La durée d’attente d’une pression sur les boutons de la manette (ou d’une touches associées au clavier) avec btnp peut être réglée. De nouveaux opérateurs en préfixe d’affection sont également disponibles , exemple  :  ..=   ,   ^=   , etc. L’accès à la mémoire est simplifiée : $<adresse> à la place de PEEK(<adresse>). etc. Les amateurs de tweet  card vont apprécier.

La fonction de parcours ipairs() vient également étendre les capacité du  language.  De nombreuses autres  ajouts et modifications sont également présents, voir liste ci-après :

Added: 8-bit character set with kana, alt font
 Added: ord(), chr()
 Added: SFX / Pattern organiser view
 Added: SFX edit buttons on pattern channels
 Added: tline // textured line drawing
 Added: SPLORE automatically updates BBS carts when online
 Added: Search for similar (shared tags) cartridges, or by thread
 Added: predefined fillp() pattern values assigned to glyphs
 Added: btnp() custom delays (poke 0x5f5c, 0x5f5d)
 Added: "." shorthand command for advancing a single frame (calls _update, _draw if they exist)
 Added: Current editor/cart view is recorded every 3 seconds to [app_data]/activity_log.txt
 Added: Cutting (ctrl-x) and pasting selected sprites while in map view to also adjust map references to those sprites
 Added: Clipboard is supported in the html exports (with some limitations) // load #wobblepaint for an example.
 Added: Can load .lua files as cartridges
 Added: Operators: ..= ^= \ \= & | ^^ << >> >>> ~ &= |= ^^= <<= >>= >>>= @ @@ $
 Added: New demo carts: waves.p8 dots3d.p8 auto2d.p8 wander.p8 cast.p8 jelpi.p8 (use INSTALL_DEMOS)
 Added: Extra pre-installed games: Embrace, 8 Legs to Love (use INSTALL_GAMES)
 Added: Splore cart labels for .p8 files
 Added: Now 16 code tabs (click on the rightmost ones to scroll)
 Added: ipairs()
 Added: SAVE from commandline to quick-save current cartridge (same as ctrl-s)
 Added: BACKUP from commandline to save a backup of current cartridge
 Added: CPU usage widget (ctrl-p while running cartridge)
 Added: Button / dpad states exposed in memory at 0x5f4c (8 bytes)
 Added: Random number generator state exposed at 0x5f44 (8 bytes)
 Added: pico8_dyn version is included when exporting to Raspberry Pi
 Added: allow_function_keys option in config.txt (CTRL 6..9 are now preferred -- will phase out F6..F9 if practical)
 Added: Visible tab characters (draw_tabs in config.txt)
 Added: pal(16,{1,2,3..}) means: use the value for each key 0..15 in a table
 Added: palt(16, bitfield) means: set the colour transparency for all 16 colours, starting with the highest bit
 Added: Options menu for binary exports (sound / fullscreen / controls)
 Added: Shape drawing tools in sprite and map editor
 Improved: Miscellaneous HTML shell / player optimisations and adjustments
 Improved: Lower cpu usage for small foreground_sleep_ms values (changed host event loop & fps switching strategy)
 Changed: This update is called 0.2.0, not 0.1.12d! (grew into plans for 0.2.0, and bumped cart version number)
 Changed: negative numbers expressed with a '-' count as a single token
 Changed: glitchy reset effect does not leave residue in base RAM (but maybe on screen when using sprites / tiles)
 Changed: sset() with 2 parameters uses the draw state colour as default
 Changed: line() or line(col) can be used to skip drawing and set the (line_x1, line_y1) state on the next call to line(x1,y1)
 Changed: vital system functions (load, reboot etc.) can only be overwritten during cartridge execution
 Changed: sqrt(x) is now more accurate, and a little faster than x^.5
 Changed: sqrt(x) returns 0 for negative values of x
 Changed: btnp() delay and repeats now work independently per-button
 Changed: pairs(nil) returns an empty function
 Changed: Default screenshot scale (now 4x), gif scale (now 3x)
 Changed: gif_len now means the length when no start point is specified (used to be the maximum recordable length)
 Changed: (Multicarts) When loading data from many different carts, the swap delay maxes out at ~2 seconds
 Changed: (Raspberry Pi) removed support for (and dependency on) libsndio
 Changed: camera(), cursor(), color(), pal(), palt(), fillp(), clip() return their previous state
 Changed: Can not call folder() from a BBS cart running under splore
 Changed: F9 resets the video, so that multiple presses results in a sequence of clips that can be joined to together
 Changed: color() defaults to 6 (was 0)
 Changed: Backed up filenames are prefixed with a timestamp.
 Changed: Automatically start on the (host's) current path if it is inside PICO-8's root path
 Changed: tostr(x,true) can also be used to view the hex value of functions and tables (uses Lua's tostring)
 Changed: Can hold control when clicking number fields (spd, pattern index etc.) to increment/decrement by 4 (was shift)
