269 256 color (8 bit) storage format, because the Allegro game library
270 cannot handle PCX files with less than 256 colors (contributed
271 graphics are not affected and might look wrong in the DOS version)
273 2003-08-16 src/init.c
274 * fixed bug which (for example) crashed the level editor when defining
275 "dynamite.EDITOR: [NONE]", because graphics may not be undefined
276 (only set to default) -- invalid graphics now set to default graphic
278 2003-08-16 src/init.c
279 * fixed graphical bug of player digging/collecting/snapping element
280 when no corresponding graphic/animation is defined for this action,
281 resulting in player being drawn as EL_EMPTY (which should only be
282 done to elements being collected, but not to the player)
284 2003-08-16 src/game.c
285 * fixed small graphical bug of player not totally moving into exit
287 2003-08-16 src/libgame/setup.c

309 * fixed bug with missing graphic for active red disk bomb
311 2003-08-07 src/files.c, src/editor.c src/game.c, src/main.h
312 * Extended variable "level.gravity" to "level.initial_gravity" and
313 "game.current_gravity" to prevent level setting from being changed
314 by playing the level (keeping the runtime value after playing).
316 * Fixed graphics bug when digging element that has 'crumbled' graphic
317 definition, but not 'diggable' graphic definition.
320 * Version number set to 3.0.1.
323 * Version 3.0.0 released.
326 * various bug fixes; among others:

355 * graphics, sounds and music now fully configurable
356 * bug fixed that prevented walking through tubes when gravity on
358 2002-04-02 src/events.c, src/editor.c
359 * Make Escape key less aggressive when playing or when editing level.
360 This can be configured as an option in the setup menu. (Default is
361 "less aggressive" which means "ask user if something can be lost"
362 when pressing the Escape key.)
364 2002-04-02 src/screen.c
365 * Added "graphics setup" screen.
367 2002-04-01 src/screen.c
368 * Changed "choose level" setup screen stuff to be more generic (to
369 make it easier to add more "choose from generic tree" setup screens).
371 2002-04-01 src/config.c, src/timestamp.h
372 * Added source files "src/config.[ch]" and "src/timestamp.h" (which
373 automatically gets created by "src/Makefile" and contains an actual
374 compile-time timestamp to identify development versions of the game).
376 2002-03-31 src/tape.c, src/events.c
377 * Added quick game/tape save/load functions to tape stuff which can be
378 invoked by a keyboard shortcut. Default: "F1" saves game/tape, "F2"
379 loads previously recorded tape and directly goes into recording mode
380 from the end of the tape (therefore appending to the tape).
382 2002-03-31 src/tape.c
383 * Added "index mark" function to tape recorder. When playing or
384 recording, "eject" button changes to "index" button. Setting index
385 mark is not yet implemented, but pressing index button when playing
386 allows very quick advancing to end of tape (when normal playing),
387 very fast forward mode (when playing with normal fast forward) or
388 very fast reaching of "pause before end of tape" (when playing with
389 "pause before end" playing mode).
391 2002-03-30 src/cartoons.c
392 * Moved some stuff from cartoons.c to the new "src/libgame/toons.c".
394 2002-03-29 src/screen.c
395 * Changed setup screen stuff to be more generic (to make it easier
396 to add more setup screens).
398 2002-03-23 src/main.c, src/main.h
399 * Various changes due to the introduction of the new libgame files
400 "setup.c" and "joystick.c".
402 2002-03-23 src/files.c
403 * Generic parts of "src/files.c" (mainly setup and level directory
404 stuff) moved to new libgame file "src/libgame/setup.c".
406 2002-03-23 src/joystick.c
407 * File "src/joystick.c" moved to libgame source tree, with
408 correspondig changes.
410 2002-03-22 src/screens.c
411 * "HandleChooseLevel()": Another bug in level series navigation fixed.
412 (Wrong level series information displayed when entering main group.)
414 2002-03-22 src/editor.c
415 * Slight change to support new gadget event "GD_EVENT_INFO_LEAVING".
417 2002-03-22 src/editor.c
418 * Changed behaviour of "Escape" key in level editor to be more
419 intuitive: When in "Element Properties" or "Level Info" mode,
420 return to "Drawing Mode" instead of leaving the level editor.
422 2002-03-21 src/game.c, src/editor.c, src/files.c
423 * 2.0.1 introduced the corrected "Emerald Mine" style behaviour of
424 gems (emeralds, diamonds, ...) slipping down from normal wall,
425 steel wall and growing wall (as in E.M.C. style levels). Although
426 the behaviour of contributed and private levels wasn't changed (due
427 to the use of "level.game_version"; see previous entry), editing
428 those levels will (of course) change the behaviour accordingly.
430 This change seems a bit too hard after thinking about it, because
431 the EM style behaviour is not the "expected" behaviour (gems would
432 normally only slip down from "rounded" walls). Therefore this was
433 now changed to an element property for gem style elements, with the
434 default setting "off" (which means: no special EM style behaviour).
435 To fix older converted levels, this flag is set to "on" for pre-2.0
436 levels that are neither contributed nor private levels.
438 2002-03-20 src/files.h
439 * Corrected settings for "level.game_version" depending of level type.
440 (Contributed and private levels always get played with game engine
441 version they were created with, while converted levels always get
442 played with the most recent version of the game engine, to let new
443 corrections of the emulation behaviour take effect.)
445 2002-03-20 src/main.h
446 * Added "#include <time.h>". This seems to be needed by "tape.c" for
447 compiling the SDL version on some systems.
448 Thanks to the several people who pointed this out.
451 * Version number set to 2.0.2.
454 * Version 2.0.1 released.
456 2002-03-18 src/screens.c
457 * "HandleChooseLevel()": Small bug in level series navigation fixed.
459 2002-03-18 src/files.c [src/libgame/misc.c]
460 * Moved some common functions from src/files.c to src/libgame/misc.c.
462 2002-03-18 src/files.c [src/libgame/misc.c]
463 * Changed permissions for new directories and saved files (especially
464 score files) according to suggestions of Debian users and mantainers.
465 Thanks to Drew Parsons <dparsons@emerall.com> for the patch.
467 2002-03-17 src/files.c
468 * Changed "{Load|Save}{Level|Tape}()" to IFF style file format:
469 Replaced "cookie" header string ("ROCKSNDIAMONDS_...\n") with
470 real IFF style header "RND1....XXXX" (where "XXXX" is "CAVE"
471 for levels and "TAPE" for tapes). Old "cookie" style format is
472 still supported for reading. New level and tape files are written
475 * New IFF chunk "VERS" contains version numbers for file and game
476 (where "game version" is the version of the program that wrote the
477 file, and "file version" is a version number to distinguish files
478 with different format, for example after adding new features).
480 2002-03-15 src/screen.c
481 * "DrawHallOfFame()": "FadeSounds()" when entering the hall of fame.
482 (Before, you heard a mixture of the in-game music and the
485 2002-03-14 src/events.c
486 * Function "DumpTape()" (files.c) now available by pressing 't' from
487 main menu (when in DEBUG mode).
489 2002-03-14 src/game.c
490 * "GameWon()": When game was won playing a tape, now there is no delay
491 raising the score and no corresponding sound is played.
493 2002-03-14 src/files.c
494 * Changed "LoadTape()" for real chunk support and also adjusted
495 "SaveTape()" accordingly.
497 2002-03-14 src/game.c, src/tape.c, src/files.c
498 * Important changes to tape format: The old tape format stored all
499 actions with a real effect with a corresponding delay between the
500 stored actions. This had some major disadvantages (for example,
501 push delays had to be ignored, pressing a button for some seconds
502 mutated to several single button presses because of the non-action
503 delays between two action frames etc.). The new tape format just
504 stupidly records all device actions and replays them later. I really
505 don't know why I haven't solved it that way before?! Old-style tapes
506 (with tape file version less than 2.0) get converted to the new
507 format on-the-fly when loading and can therefore still be played;
508 only some minor parts of the old-style tape handling code was needed.
509 (A perfect conversion is not possible, because there is information
510 missing about the device actions between two action frames.)
512 2002-03-14 src/files.c
513 * New function "DumpTape()" to dump the contents of the current tape
514 in a human readable format.
516 2002-03-14 src/game.c
517 * Small tape bug fixed: When automatically advancing to next level
518 after a game was won, the tape from the previous level still was
519 loaded as a tape for the new level.
521 2002-03-14 src/tape.c
522 * Small graphical bug fixed: When pressing ""Record" or "Play" on
523 tape, cartoons did not get completely removed because
524 StopAnimation() was not called.
526 2002-03-13 src/files.c
527 * Changed "LoadLevel()" and "SaveLevel()" to add new chunk "CNT2".
528 Fixed bug of "CONT" and "BODY" (chunk size was set to 8-bit element
529 size even when using 16-bit elements). Added new chunk "CNT2" for
530 16-bit amoeba content (previously written in 8-bit field in "HEAD"
531 chunk even when content was 16-bit element). "CNT2" should now be
532 able to store content for arbitrary elements (up to eight blocks of
533 3 x 3 element arrays). All "CNT2" elements will always be stored as
534 16-bit elements. "CONT" (with 8/16-bit elements) now obsolete.
536 2002-03-13 src/files.c
537 * Changed "LoadLevel()" for real chunk support.
539 2002-03-12 src/game.c
540 * Fixed problem (introduced after 2.0.0 release) with penguins
541 not getting killed by enemies
543 2002-02-24 src/game.c, src/main.h
544 * Added "player->is_moving"; now "player->last_move_dir" does
545 not contain any information if the player is just moving at
547 Before, "player->last_move_dir" was misused for this purpose
548 for the robot stuff (robots don't kill players when they are
549 moving). But setting "player->last_move_dir" to MV_NO_MOVING
550 broke tapes when walking through pipes!
551 ("IS_MOVING()" uses "MovPos[][]", but this fails when it is 0
552 in a continuous movement. This fact is ignored for friends and
