From: Svjatoslav Agejenko Date: Sat, 22 Aug 2026 15:28:51 +0000 (+0300) Subject: docs: recapture gallery media and sync all index pages X-Git-Url: http://www2.svjatoslav.eu/gitweb/?a=commitdiff_plain;h=2e7c2d118f26f84348a5b4d40248e68f2b39e66e;p=qbasicapps.git docs: recapture gallery media and sync all index pages - Replace legacy .webm/.png captures with ' - Screencast N.mp4' and ' - Screenshot N.png' files across 2D GFX, 3D GFX, Games, Math, Miscellaneous, Networking and Tutorial - Point every index.org video/image reference at the new captures; sections whose screenshots were recaptured as screencasts now embed video blocks - Fix broken source links: Bouncing cubes wrong directory prefix, copy-pasted '!.bas' links in Galaxy/Universe explorer, Alarm comma filenames, Pomppu Paavo moved into its own subdirectory - Add 'Back to BASIC applications collection' parent link to all 13 topic pages - worm.bas: guard tail/head ring-buffer pointers against out-of-range access for dead or overgrown worms - Stars.bas: drop spurious totalStars increment in galaxy creation - Anaglyph.bas, Tiled room.bas: emit SOUND 0, .5 at main loop start --- diff --git a/2D GFX/Animations/index.org b/2D GFX/Animations/index.org index 0abf179..3daaac8 100644 --- a/2D GFX/Animations/index.org +++ b/2D GFX/Animations/index.org @@ -26,6 +26,7 @@ #+end_export +[[file:../index.org][Back to BASIC applications collection]] * Bump mapping diff --git a/2D GFX/Fractals/index.org b/2D GFX/Fractals/index.org index 81f770f..0569bd8 100644 --- a/2D GFX/Fractals/index.org +++ b/2D GFX/Fractals/index.org @@ -26,6 +26,7 @@ #+end_export +[[file:../index.org][Back to BASIC applications collection]] * Fractal circles diff --git a/2D GFX/Hello friend -
