2960 Fixed property "can fall" for run-time element "EL_AMOEBA_DROPPING"
2962 Bug was introduced in version:
2965 Bug was fixed in version:
2969 In version 2.0.1, a new run-time element "EL_AMOEBA_DROPPING" was added,
2970 but the property "can fall" was missing, which caused some levels to be
2971 unsolvable. This was fixed in version 4.2.0.0.
2973 Affected levels/tapes:
2974 An example for a tape that was fixed by this bugfix is tape 029 from the
2975 level set "rnd_sam_bateman".
2976 The wrong behaviour will still be used for all levels or tapes that were
2977 created/recorded with it. An example for this is tape 023 from the level
2978 set "rnd_gerhard_haeusler", which was recorded with a buggy game engine.
2981 boolean use_amoeba_dropping_cannot_fall_bug =
2982 ((game.engine_version >= VERSION_IDENT(2,0,1,0) &&
2983 game.engine_version < VERSION_IDENT(4,2,0,0)) ||
2985 tape.game_version >= VERSION_IDENT(2,0,1,0) &&
2986 tape.game_version < VERSION_IDENT(4,2,0,0)));
2989 Summary of bugfix/change:
2990 Fixed move speed of elements entering or leaving magic wall.
2992 Fixed/changed in version:
2996 Before 2.0.1, move speed of elements entering or leaving magic wall was
2997 twice as fast as it is now.
2998 Since 2.0.1, this is set to a lower value by using move_stepsize_list[].
3000 Affected levels/tapes:
3001 The first condition is generally needed for all levels/tapes before version
3002 2.0.1, which might use the old behaviour before it was changed; known tapes
3003 that are affected: Tape 014 from the level set "rnd_conor_mancone".
3004 The second condition is an exception from the above case and is needed for
3005 the special case of tapes recorded with game (not engine!) version 2.0.1 or
3006 above, but before it was known that this change would break tapes like the
3007 above and was fixed in 4.2.0.0, so that the changed behaviour was active
3008 although the engine version while recording maybe was before 2.0.1. There
3009 are a lot of tapes that are affected by this exception, like tape 006 from
3010 the level set "rnd_conor_mancone".
3013 boolean use_old_move_stepsize_for_magic_wall =
3014 (game.engine_version < VERSION_IDENT(2,0,1,0) &&
3016 tape.game_version >= VERSION_IDENT(2,0,1,0) &&
3017 tape.game_version < VERSION_IDENT(4,2,0,0)));
3020 Summary of bugfix/change:
3021 Fixed handling for custom elements that change when pushed by the player.
3023 Fixed/changed in version:
3027 Before 3.1.0, custom elements that "change when pushing" changed directly
3028 after the player started pushing them (until then handled in "DigField()").
3029 Since 3.1.0, these custom elements are not changed until the "pushing"
3030 move of the element is finished (now handled in "ContinueMoving()").
3032 Affected levels/tapes:
3033 The first condition is generally needed for all levels/tapes before version
3034 3.1.0, which might use the old behaviour before it was changed; known tapes
3035 that are affected are some tapes from the level set "Walpurgis Gardens" by
3037 The second condition is an exception from the above case and is needed for
3038 the special case of tapes recorded with game (not engine!) version 3.1.0 or
3039 above (including some development versions of 3.1.0), but before it was
3040 known that this change would break tapes like the above and was fixed in
3041 3.1.1, so that the changed behaviour was active although the engine version
3042 while recording maybe was before 3.1.0. There is at least one tape that is
3043 affected by this exception, which is the tape for the one-level set "Bug
3044 Machine" by Juergen Bonhagen.
3047 game.use_change_when_pushing_bug =
3048 (game.engine_version < VERSION_IDENT(3,1,0,0) &&
3050 tape.game_version >= VERSION_IDENT(3,1,0,0) &&
3051 tape.game_version < VERSION_IDENT(3,1,1,0)));
3054 Summary of bugfix/change:
3055 Fixed handling for blocking the field the player leaves when moving.
3057 Fixed/changed in version:
3061 Before 3.1.1, when "block last field when moving" was enabled, the field
3062 the player is leaving when moving was blocked for the time of the move,
3063 and was directly unblocked afterwards. This resulted in the last field
3064 being blocked for exactly one less than the number of frames of one player
3065 move. Additionally, even when blocking was disabled, the last field was
3066 blocked for exactly one frame.
3067 Since 3.1.1, due to changes in player movement handling, the last field
3068 is not blocked at all when blocking is disabled. When blocking is enabled,
3069 the last field is blocked for exactly the number of frames of one player
3070 move. Additionally, if the player is Murphy, the hero of Supaplex, the
3071 last field is blocked for exactly one more than the number of frames of

10952 GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
10954 When using an animation frame delay of 1 (this only happens with
10955 "sp_zonk.moving.left/right" in the classic graphics), the default
10956 (non-moving) animation shows wrong animation frames (while the
10957 moving animation, like "sp_zonk.moving.left/right", is correct,
10958 so this graphical bug never shows up with the classic graphics).
10959 For an animation with 4 frames, this causes wrong frames 0,0,1,2
10960 be drawn instead of the correct frames 0,1,2,3. This is caused by
10961 "GfxFrame[][]" being reset *twice* (in two successive frames) after
10962 an element change: First when the change delay ("ChangeDelay[][]")
10963 counter has reached zero after decrementing, then a second time in
10964 the next frame (after "GfxFrame[][]" was already incremented) when
10965 "ChangeDelay[][]" is reset to the initial delay value again.
10967 This causes frame 0 to be drawn twice, while the last frame won't
10968 be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
10970 As some animations may already be cleverly designed around this bug
10971 (at least the "Snake Bite" snake tail animation does this), it cannot
10972 simply be fixed here without breaking such existing animations.
10973 Unfortunately, it cannot easily be detected if a graphics set was
10974 designed "before" or "after" the bug was fixed. As a workaround,
10975 a new graphics set option "game.graphics_engine_version" was added
10976 to be able to specify the game's major release version for which the
10977 graphics set was designed, which can then be used to decide if the
10978 bugfix should be used (version 4 and above) or not (version 3 or
10979 below, or if no version was specified at all, as with old sets).
10981 (The wrong/fixed animation frames can be tested with the test level set
10982 "test_gfxframe" and level "000", which contains a specially prepared
10983 custom element at level position (x/y) == (11/9) which uses the zonk
10984 animation mentioned above. Using "game.graphics_engine_version: 4"
10985 fixes the wrong animation frames, showing the correct frames 0,1,2,3.
10986 This can also be seen from the debug output for this test element.)
