287 256 color (8 bit) storage format, because the Allegro game library
288 cannot handle PCX files with less than 256 colors (contributed
289 graphics are not affected and might look wrong in the DOS version)
291 2003-08-16 src/init.c
292 * fixed bug which (for example) crashed the level editor when defining
293 "dynamite.EDITOR: [NONE]", because graphics may not be undefined
294 (only set to default) -- invalid graphics now set to default graphic
296 2003-08-16 src/init.c
297 * fixed graphical bug of player digging/collecting/snapping element
298 when no corresponding graphic/animation is defined for this action,
299 resulting in player being drawn as EL_EMPTY (which should only be
300 done to elements being collected, but not to the player)
302 2003-08-16 src/game.c
303 * fixed small graphical bug of player not totally moving into exit
305 2003-08-16 src/libgame/setup.c

327 * fixed bug with missing graphic for active red disk bomb
329 2003-08-07 src/files.c, src/editor.c src/game.c, src/main.h
330 * Extended variable "level.gravity" to "level.initial_gravity" and
331 "game.current_gravity" to prevent level setting from being changed
332 by playing the level (keeping the runtime value after playing).
334 * Fixed graphics bug when digging element that has 'crumbled' graphic
335 definition, but not 'diggable' graphic definition.
338 * Version number set to 3.0.1.
341 * Version 3.0.0 released.

367 * Version 2.1.0 released.
370 * Version number set to 2.1.0.
372 2002-04-03 to 2002-05-19 (various source files)
373 * graphics, sounds and music now fully configurable
374 * bug fixed that prevented walking through tubes when gravity on
376 2002-04-02 src/events.c, src/editor.c
377 * Make Escape key less aggressive when playing or when editing level.
378 This can be configured as an option in the setup menu. (Default is
379 "less aggressive" which means "ask user if something can be lost"
380 when pressing the Escape key.)
382 2002-04-02 src/screen.c
383 * Added "graphics setup" screen.
385 2002-04-01 src/screen.c
386 * Changed "choose level" setup screen stuff to be more generic (to
387 make it easier to add more "choose from generic tree" setup screens).
389 2002-04-01 src/config.c, src/timestamp.h
390 * Added source files "src/config.[ch]" and "src/timestamp.h" (which
391 automatically gets created by "src/Makefile" and contains an actual
392 compile-time timestamp to identify development versions of the game).
394 2002-03-31 src/tape.c, src/events.c
395 * Added quick game/tape save/load functions to tape stuff which can be
396 invoked by a keyboard shortcut. Default: "F1" saves game/tape, "F2"
397 loads previously recorded tape and directly goes into recording mode
398 from the end of the tape (therefore appending to the tape).
400 2002-03-31 src/tape.c
401 * Added "index mark" function to tape recorder. When playing or
402 recording, "eject" button changes to "index" button. Setting index
403 mark is not yet implemented, but pressing index button when playing
404 allows very quick advancing to end of tape (when normal playing),
405 very fast forward mode (when playing with normal fast forward) or
406 very fast reaching of "pause before end of tape" (when playing with
407 "pause before end" playing mode).
409 2002-03-30 src/cartoons.c
410 * Moved some stuff from cartoons.c to the new "src/libgame/toons.c".
412 2002-03-29 src/screen.c
413 * Changed setup screen stuff to be more generic (to make it easier
414 to add more setup screens).
416 2002-03-23 src/main.c, src/main.h
417 * Various changes due to the introduction of the new libgame files
418 "setup.c" and "joystick.c".
420 2002-03-23 src/files.c
421 * Generic parts of "src/files.c" (mainly setup and level directory
422 stuff) moved to new libgame file "src/libgame/setup.c".
424 2002-03-23 src/joystick.c
425 * File "src/joystick.c" moved to libgame source tree, with
426 correspondig changes.
428 2002-03-22 src/screens.c
429 * "HandleChooseLevel()": Another bug in level series navigation fixed.
430 (Wrong level series information displayed when entering main group.)
432 2002-03-22 src/editor.c
433 * Slight change to support new gadget event "GD_EVENT_INFO_LEAVING".
435 2002-03-22 src/editor.c
436 * Changed behaviour of "Escape" key in level editor to be more
437 intuitive: When in "Element Properties" or "Level Info" mode,
438 return to "Drawing Mode" instead of leaving the level editor.
440 2002-03-21 src/game.c, src/editor.c, src/files.c
441 * 2.0.1 introduced the corrected "Emerald Mine" style behaviour of
442 gems (emeralds, diamonds, ...) slipping down from normal wall,
443 steel wall and growing wall (as in E.M.C. style levels). Although
444 the behaviour of contributed and private levels wasn't changed (due
445 to the use of "level.game_version"; see previous entry), editing
446 those levels will (of course) change the behaviour accordingly.
448 This change seems a bit too hard after thinking about it, because
449 the EM style behaviour is not the "expected" behaviour (gems would
450 normally only slip down from "rounded" walls). Therefore this was
451 now changed to an element property for gem style elements, with the
452 default setting "off" (which means: no special EM style behaviour).
453 To fix older converted levels, this flag is set to "on" for pre-2.0
454 levels that are neither contributed nor private levels.
456 2002-03-20 src/files.h
457 * Corrected settings for "level.game_version" depending of level type.
458 (Contributed and private levels always get played with game engine
459 version they were created with, while converted levels always get
460 played with the most recent version of the game engine, to let new
461 corrections of the emulation behaviour take effect.)
463 2002-03-20 src/main.h
464 * Added "#include <time.h>". This seems to be needed by "tape.c" for
465 compiling the SDL version on some systems.
466 Thanks to the several people who pointed this out.
469 * Version number set to 2.0.2.
472 * Version 2.0.1 released.
474 2002-03-18 src/screens.c
475 * "HandleChooseLevel()": Small bug in level series navigation fixed.
477 2002-03-18 src/files.c [src/libgame/misc.c]
478 * Moved some common functions from src/files.c to src/libgame/misc.c.
480 2002-03-18 src/files.c [src/libgame/misc.c]
481 * Changed permissions for new directories and saved files (especially
482 score files) according to suggestions of Debian users and mantainers.
483 Thanks to Drew Parsons <dparsons@emerall.com> for the patch.
485 2002-03-17 src/files.c
486 * Changed "{Load|Save}{Level|Tape}()" to IFF style file format:
487 Replaced "cookie" header string ("ROCKSNDIAMONDS_...\n") with
488 real IFF style header "RND1....XXXX" (where "XXXX" is "CAVE"
489 for levels and "TAPE" for tapes). Old "cookie" style format is
490 still supported for reading. New level and tape files are written
493 * New IFF chunk "VERS" contains version numbers for file and game
494 (where "game version" is the version of the program that wrote the
495 file, and "file version" is a version number to distinguish files
496 with different format, for example after adding new features).
498 2002-03-15 src/screen.c
499 * "DrawHallOfFame()": "FadeSounds()" when entering the hall of fame.
500 (Before, you heard a mixture of the in-game music and the
503 2002-03-14 src/events.c
504 * Function "DumpTape()" (files.c) now available by pressing 't' from
505 main menu (when in DEBUG mode).
507 2002-03-14 src/game.c
508 * "GameWon()": When game was won playing a tape, now there is no delay
509 raising the score and no corresponding sound is played.
511 2002-03-14 src/files.c
512 * Changed "LoadTape()" for real chunk support and also adjusted
513 "SaveTape()" accordingly.
515 2002-03-14 src/game.c, src/tape.c, src/files.c
516 * Important changes to tape format: The old tape format stored all
517 actions with a real effect with a corresponding delay between the
518 stored actions. This had some major disadvantages (for example,
519 push delays had to be ignored, pressing a button for some seconds
520 mutated to several single button presses because of the non-action
521 delays between two action frames etc.). The new tape format just
522 stupidly records all device actions and replays them later. I really
523 don't know why I haven't solved it that way before?! Old-style tapes
524 (with tape file version less than 2.0) get converted to the new
525 format on-the-fly when loading and can therefore still be played;
526 only some minor parts of the old-style tape handling code was needed.
527 (A perfect conversion is not possible, because there is information
528 missing about the device actions between two action frames.)
530 2002-03-14 src/files.c
531 * New function "DumpTape()" to dump the contents of the current tape
532 in a human readable format.
534 2002-03-14 src/game.c
535 * Small tape bug fixed: When automatically advancing to next level
536 after a game was won, the tape from the previous level still was
537 loaded as a tape for the new level.
539 2002-03-14 src/tape.c
540 * Small graphical bug fixed: When pressing ""Record" or "Play" on
541 tape, cartoons did not get completely removed because
542 StopAnimation() was not called.
544 2002-03-13 src/files.c
545 * Changed "LoadLevel()" and "SaveLevel()" to add new chunk "CNT2".
546 Fixed bug of "CONT" and "BODY" (chunk size was set to 8-bit element
547 size even when using 16-bit elements). Added new chunk "CNT2" for
548 16-bit amoeba content (previously written in 8-bit field in "HEAD"
549 chunk even when content was 16-bit element). "CNT2" should now be
550 able to store content for arbitrary elements (up to eight blocks of
551 3 x 3 element arrays). All "CNT2" elements will always be stored as
552 16-bit elements. "CONT" (with 8/16-bit elements) now obsolete.
554 2002-03-13 src/files.c
555 * Changed "LoadLevel()" for real chunk support.
557 2002-03-12 src/game.c
558 * Fixed problem (introduced after 2.0.0 release) with penguins
559 not getting killed by enemies
561 2002-02-24 src/game.c, src/main.h
562 * Added "player->is_moving"; now "player->last_move_dir" does
563 not contain any information if the player is just moving at
565 Before, "player->last_move_dir" was misused for this purpose
566 for the robot stuff (robots don't kill players when they are
567 moving). But setting "player->last_move_dir" to MV_NO_MOVING
568 broke tapes when walking through pipes!
569 ("IS_MOVING()" uses "MovPos[][]", but this fails when it is 0
570 in a continuous movement. This fact is ignored for friends and
