2972 Fixed property "can fall" for run-time element "EL_AMOEBA_DROPPING"
2974 Bug was introduced in version:
2977 Bug was fixed in version:
2981 In version 2.0.1, a new run-time element "EL_AMOEBA_DROPPING" was added,
2982 but the property "can fall" was missing, which caused some levels to be
2983 unsolvable. This was fixed in version 4.2.0.0.
2985 Affected levels/tapes:
2986 An example for a tape that was fixed by this bugfix is tape 029 from the
2987 level set "rnd_sam_bateman".
2988 The wrong behaviour will still be used for all levels or tapes that were
2989 created/recorded with it. An example for this is tape 023 from the level
2990 set "rnd_gerhard_haeusler", which was recorded with a buggy game engine.
2993 boolean use_amoeba_dropping_cannot_fall_bug =
2994 ((game.engine_version >= VERSION_IDENT(2,0,1,0) &&
2995 game.engine_version < VERSION_IDENT(4,2,0,0)) ||

2998 tape.game_version < VERSION_IDENT(4,2,0,0)));
3001 Summary of bugfix/change:
3002 Fixed move speed of elements entering or leaving magic wall.
3004 Fixed/changed in version:
3008 Before 2.0.1, move speed of elements entering or leaving magic wall was
3009 twice as fast as it is now.
3010 Since 2.0.1, this is set to a lower value by using move_stepsize_list[].
3012 Affected levels/tapes:
3013 The first condition is generally needed for all levels/tapes before version
3014 2.0.1, which might use the old behaviour before it was changed; known tapes
3015 that are affected: Tape 014 from the level set "rnd_conor_mancone".
3016 The second condition is an exception from the above case and is needed for
3017 the special case of tapes recorded with game (not engine!) version 2.0.1 or
3018 above, but before it was known that this change would break tapes like the
3019 above and was fixed in 4.2.0.0, so that the changed behaviour was active
3020 although the engine version while recording maybe was before 2.0.1. There
3021 are a lot of tapes that are affected by this exception, like tape 006 from
3022 the level set "rnd_conor_mancone".
3025 boolean use_old_move_stepsize_for_magic_wall =
3026 (game.engine_version < VERSION_IDENT(2,0,1,0) &&

3032 Summary of bugfix/change:
3033 Fixed handling for custom elements that change when pushed by the player.
3035 Fixed/changed in version:
3039 Before 3.1.0, custom elements that "change when pushing" changed directly
3040 after the player started pushing them (until then handled in "DigField()").
3041 Since 3.1.0, these custom elements are not changed until the "pushing"
3042 move of the element is finished (now handled in "ContinueMoving()").
3044 Affected levels/tapes:
3045 The first condition is generally needed for all levels/tapes before version
3046 3.1.0, which might use the old behaviour before it was changed; known tapes
3047 that are affected are some tapes from the level set "Walpurgis Gardens" by
3049 The second condition is an exception from the above case and is needed for
3050 the special case of tapes recorded with game (not engine!) version 3.1.0 or
3051 above (including some development versions of 3.1.0), but before it was
3052 known that this change would break tapes like the above and was fixed in
3053 3.1.1, so that the changed behaviour was active although the engine version
3054 while recording maybe was before 3.1.0. There is at least one tape that is
3055 affected by this exception, which is the tape for the one-level set "Bug
3056 Machine" by Juergen Bonhagen.

3066 Summary of bugfix/change:
3067 Fixed handling for blocking the field the player leaves when moving.
3069 Fixed/changed in version:
3073 Before 3.1.1, when "block last field when moving" was enabled, the field
3074 the player is leaving when moving was blocked for the time of the move,
3075 and was directly unblocked afterwards. This resulted in the last field
3076 being blocked for exactly one less than the number of frames of one player
3077 move. Additionally, even when blocking was disabled, the last field was
3078 blocked for exactly one frame.
3079 Since 3.1.1, due to changes in player movement handling, the last field
3080 is not blocked at all when blocking is disabled. When blocking is enabled,
3081 the last field is blocked for exactly the number of frames of one player
3082 move. Additionally, if the player is Murphy, the hero of Supaplex, the
3083 last field is blocked for exactly one more than the number of frames of

10900 GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
10902 When using an animation frame delay of 1 (this only happens with
10903 "sp_zonk.moving.left/right" in the classic graphics), the default
10904 (non-moving) animation shows wrong animation frames (while the
10905 moving animation, like "sp_zonk.moving.left/right", is correct,
10906 so this graphical bug never shows up with the classic graphics).
10907 For an animation with 4 frames, this causes wrong frames 0,0,1,2
10908 be drawn instead of the correct frames 0,1,2,3. This is caused by
10909 "GfxFrame[][]" being reset *twice* (in two successive frames) after
10910 an element change: First when the change delay ("ChangeDelay[][]")
10911 counter has reached zero after decrementing, then a second time in
10912 the next frame (after "GfxFrame[][]" was already incremented) when
10913 "ChangeDelay[][]" is reset to the initial delay value again.
10915 This causes frame 0 to be drawn twice, while the last frame won't
10916 be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
10918 As some animations may already be cleverly designed around this bug
10919 (at least the "Snake Bite" snake tail animation does this), it cannot
10920 simply be fixed here without breaking such existing animations.
10921 Unfortunately, it cannot easily be detected if a graphics set was
10922 designed "before" or "after" the bug was fixed. As a workaround,
10923 a new graphics set option "game.graphics_engine_version" was added
10924 to be able to specify the game's major release version for which the
10925 graphics set was designed, which can then be used to decide if the
10926 bugfix should be used (version 4 and above) or not (version 3 or
10927 below, or if no version was specified at all, as with old sets).
10929 (The wrong/fixed animation frames can be tested with the test level set
10930 "test_gfxframe" and level "000", which contains a specially prepared
10931 custom element at level position (x/y) == (11/9) which uses the zonk
10932 animation mentioned above. Using "game.graphics_engine_version: 4"
10933 fixes the wrong animation frames, showing the correct frames 0,1,2,3.
