275 256 color (8 bit) storage format, because the Allegro game library
276 cannot handle PCX files with less than 256 colors (contributed
277 graphics are not affected and might look wrong in the DOS version)
279 2003-08-16 src/init.c
280 * fixed bug which (for example) crashed the level editor when defining
281 "dynamite.EDITOR: [NONE]", because graphics may not be undefined
282 (only set to default) -- invalid graphics now set to default graphic
284 2003-08-16 src/init.c
285 * fixed graphical bug of player digging/collecting/snapping element
286 when no corresponding graphic/animation is defined for this action,
287 resulting in player being drawn as EL_EMPTY (which should only be
288 done to elements being collected, but not to the player)
290 2003-08-16 src/game.c
291 * fixed small graphical bug of player not totally moving into exit
293 2003-08-16 src/libgame/setup.c

315 * fixed bug with missing graphic for active red disk bomb
317 2003-08-07 src/files.c, src/editor.c src/game.c, src/main.h
318 * Extended variable "level.gravity" to "level.initial_gravity" and
319 "game.current_gravity" to prevent level setting from being changed
320 by playing the level (keeping the runtime value after playing).
322 * Fixed graphics bug when digging element that has 'crumbled' graphic
323 definition, but not 'diggable' graphic definition.
326 * Version number set to 3.0.1.
329 * Version 3.0.0 released.
332 * various bug fixes; among others:

355 * Version 2.1.0 released.
358 * Version number set to 2.1.0.
360 2002-04-03 to 2002-05-19 (various source files)
361 * graphics, sounds and music now fully configurable
362 * bug fixed that prevented walking through tubes when gravity on
364 2002-04-02 src/events.c, src/editor.c
365 * Make Escape key less aggressive when playing or when editing level.
366 This can be configured as an option in the setup menu. (Default is
367 "less aggressive" which means "ask user if something can be lost"
368 when pressing the Escape key.)
370 2002-04-02 src/screen.c
371 * Added "graphics setup" screen.
373 2002-04-01 src/screen.c
374 * Changed "choose level" setup screen stuff to be more generic (to
375 make it easier to add more "choose from generic tree" setup screens).
377 2002-04-01 src/config.c, src/timestamp.h
378 * Added source files "src/config.[ch]" and "src/timestamp.h" (which
379 automatically gets created by "src/Makefile" and contains an actual
380 compile-time timestamp to identify development versions of the game).
382 2002-03-31 src/tape.c, src/events.c
383 * Added quick game/tape save/load functions to tape stuff which can be
384 invoked by a keyboard shortcut. Default: "F1" saves game/tape, "F2"
385 loads previously recorded tape and directly goes into recording mode
386 from the end of the tape (therefore appending to the tape).
388 2002-03-31 src/tape.c
389 * Added "index mark" function to tape recorder. When playing or
390 recording, "eject" button changes to "index" button. Setting index
391 mark is not yet implemented, but pressing index button when playing
392 allows very quick advancing to end of tape (when normal playing),
393 very fast forward mode (when playing with normal fast forward) or
394 very fast reaching of "pause before end of tape" (when playing with
395 "pause before end" playing mode).
397 2002-03-30 src/cartoons.c
398 * Moved some stuff from cartoons.c to the new "src/libgame/toons.c".
400 2002-03-29 src/screen.c
401 * Changed setup screen stuff to be more generic (to make it easier
402 to add more setup screens).
404 2002-03-23 src/main.c, src/main.h
405 * Various changes due to the introduction of the new libgame files
406 "setup.c" and "joystick.c".
408 2002-03-23 src/files.c
409 * Generic parts of "src/files.c" (mainly setup and level directory
410 stuff) moved to new libgame file "src/libgame/setup.c".
412 2002-03-23 src/joystick.c
413 * File "src/joystick.c" moved to libgame source tree, with
414 correspondig changes.
416 2002-03-22 src/screens.c
417 * "HandleChooseLevel()": Another bug in level series navigation fixed.
418 (Wrong level series information displayed when entering main group.)
420 2002-03-22 src/editor.c
421 * Slight change to support new gadget event "GD_EVENT_INFO_LEAVING".
423 2002-03-22 src/editor.c
424 * Changed behaviour of "Escape" key in level editor to be more
425 intuitive: When in "Element Properties" or "Level Info" mode,
426 return to "Drawing Mode" instead of leaving the level editor.
428 2002-03-21 src/game.c, src/editor.c, src/files.c
429 * 2.0.1 introduced the corrected "Emerald Mine" style behaviour of
430 gems (emeralds, diamonds, ...) slipping down from normal wall,
431 steel wall and growing wall (as in E.M.C. style levels). Although
432 the behaviour of contributed and private levels wasn't changed (due
433 to the use of "level.game_version"; see previous entry), editing
434 those levels will (of course) change the behaviour accordingly.
436 This change seems a bit too hard after thinking about it, because
437 the EM style behaviour is not the "expected" behaviour (gems would
438 normally only slip down from "rounded" walls). Therefore this was
439 now changed to an element property for gem style elements, with the
440 default setting "off" (which means: no special EM style behaviour).
441 To fix older converted levels, this flag is set to "on" for pre-2.0
442 levels that are neither contributed nor private levels.
444 2002-03-20 src/files.h
445 * Corrected settings for "level.game_version" depending of level type.
446 (Contributed and private levels always get played with game engine
447 version they were created with, while converted levels always get
448 played with the most recent version of the game engine, to let new
449 corrections of the emulation behaviour take effect.)
451 2002-03-20 src/main.h
452 * Added "#include <time.h>". This seems to be needed by "tape.c" for
453 compiling the SDL version on some systems.
454 Thanks to the several people who pointed this out.
457 * Version number set to 2.0.2.
460 * Version 2.0.1 released.
462 2002-03-18 src/screens.c
463 * "HandleChooseLevel()": Small bug in level series navigation fixed.
465 2002-03-18 src/files.c [src/libgame/misc.c]
466 * Moved some common functions from src/files.c to src/libgame/misc.c.
468 2002-03-18 src/files.c [src/libgame/misc.c]
469 * Changed permissions for new directories and saved files (especially
470 score files) according to suggestions of Debian users and mantainers.
471 Thanks to Drew Parsons <dparsons@emerall.com> for the patch.
473 2002-03-17 src/files.c
474 * Changed "{Load|Save}{Level|Tape}()" to IFF style file format:
475 Replaced "cookie" header string ("ROCKSNDIAMONDS_...\n") with
476 real IFF style header "RND1....XXXX" (where "XXXX" is "CAVE"
477 for levels and "TAPE" for tapes). Old "cookie" style format is
478 still supported for reading. New level and tape files are written
481 * New IFF chunk "VERS" contains version numbers for file and game
482 (where "game version" is the version of the program that wrote the
483 file, and "file version" is a version number to distinguish files
484 with different format, for example after adding new features).
486 2002-03-15 src/screen.c
487 * "DrawHallOfFame()": "FadeSounds()" when entering the hall of fame.
488 (Before, you heard a mixture of the in-game music and the
491 2002-03-14 src/events.c
492 * Function "DumpTape()" (files.c) now available by pressing 't' from
493 main menu (when in DEBUG mode).
495 2002-03-14 src/game.c
496 * "GameWon()": When game was won playing a tape, now there is no delay
497 raising the score and no corresponding sound is played.
499 2002-03-14 src/files.c
500 * Changed "LoadTape()" for real chunk support and also adjusted
501 "SaveTape()" accordingly.
503 2002-03-14 src/game.c, src/tape.c, src/files.c
504 * Important changes to tape format: The old tape format stored all
505 actions with a real effect with a corresponding delay between the
506 stored actions. This had some major disadvantages (for example,
507 push delays had to be ignored, pressing a button for some seconds
508 mutated to several single button presses because of the non-action
509 delays between two action frames etc.). The new tape format just
510 stupidly records all device actions and replays them later. I really
511 don't know why I haven't solved it that way before?! Old-style tapes
512 (with tape file version less than 2.0) get converted to the new
513 format on-the-fly when loading and can therefore still be played;
514 only some minor parts of the old-style tape handling code was needed.
515 (A perfect conversion is not possible, because there is information
516 missing about the device actions between two action frames.)
518 2002-03-14 src/files.c
519 * New function "DumpTape()" to dump the contents of the current tape
520 in a human readable format.
522 2002-03-14 src/game.c
523 * Small tape bug fixed: When automatically advancing to next level
524 after a game was won, the tape from the previous level still was
525 loaded as a tape for the new level.
527 2002-03-14 src/tape.c
528 * Small graphical bug fixed: When pressing ""Record" or "Play" on
529 tape, cartoons did not get completely removed because
530 StopAnimation() was not called.
532 2002-03-13 src/files.c
533 * Changed "LoadLevel()" and "SaveLevel()" to add new chunk "CNT2".
534 Fixed bug of "CONT" and "BODY" (chunk size was set to 8-bit element
535 size even when using 16-bit elements). Added new chunk "CNT2" for
536 16-bit amoeba content (previously written in 8-bit field in "HEAD"
537 chunk even when content was 16-bit element). "CNT2" should now be
538 able to store content for arbitrary elements (up to eight blocks of
539 3 x 3 element arrays). All "CNT2" elements will always be stored as
540 16-bit elements. "CONT" (with 8/16-bit elements) now obsolete.
542 2002-03-13 src/files.c
543 * Changed "LoadLevel()" for real chunk support.
545 2002-03-12 src/game.c
546 * Fixed problem (introduced after 2.0.0 release) with penguins
547 not getting killed by enemies
549 2002-02-24 src/game.c, src/main.h
550 * Added "player->is_moving"; now "player->last_move_dir" does
551 not contain any information if the player is just moving at
553 Before, "player->last_move_dir" was misused for this purpose
554 for the robot stuff (robots don't kill players when they are
555 moving). But setting "player->last_move_dir" to MV_NO_MOVING
556 broke tapes when walking through pipes!
557 ("IS_MOVING()" uses "MovPos[][]", but this fails when it is 0
558 in a continuous movement. This fact is ignored for friends and
