2846 Summary of bugfix/change:
2847 Fixed handling for custom elements that change when pushed by the player.
2849 Fixed/changed in version:
2853 Before 3.1.0, custom elements that "change when pushing" changed directly
2854 after the player started pushing them (until then handled in "DigField()").
2855 Since 3.1.0, these custom elements are not changed until the "pushing"
2856 move of the element is finished (now handled in "ContinueMoving()").
2858 Affected levels/tapes:
2859 The first condition is generally needed for all levels/tapes before version
2860 3.1.0, which might use the old behaviour before it was changed; known tapes
2861 that are affected are some tapes from the level set "Walpurgis Gardens" by
2863 The second condition is an exception from the above case and is needed for
2864 the special case of tapes recorded with game (not engine!) version 3.1.0 or
2865 above (including some development versions of 3.1.0), but before it was
2866 known that this change would break tapes like the above and was fixed in
2867 3.1.1, so that the changed behaviour was active although the engine version
2868 while recording maybe was before 3.1.0. There is at least one tape that is
2869 affected by this exception, which is the tape for the one-level set "Bug
2870 Machine" by Juergen Bonhagen.
2873 game.use_change_when_pushing_bug =
2874 (game.engine_version < VERSION_IDENT(3,1,0,0) &&
2876 tape.game_version >= VERSION_IDENT(3,1,0,0) &&
2877 tape.game_version < VERSION_IDENT(3,1,1,0)));
2880 Summary of bugfix/change:
2881 Fixed handling for blocking the field the player leaves when moving.
2883 Fixed/changed in version:
2887 Before 3.1.1, when "block last field when moving" was enabled, the field
2888 the player is leaving when moving was blocked for the time of the move,
2889 and was directly unblocked afterwards. This resulted in the last field
2890 being blocked for exactly one less than the number of frames of one player
2891 move. Additionally, even when blocking was disabled, the last field was
2892 blocked for exactly one frame.
2893 Since 3.1.1, due to changes in player movement handling, the last field
2894 is not blocked at all when blocking is disabled. When blocking is enabled,
2895 the last field is blocked for exactly the number of frames of one player
2896 move. Additionally, if the player is Murphy, the hero of Supaplex, the
2897 last field is blocked for exactly one more than the number of frames of

10538 GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
10540 When using an animation frame delay of 1 (this only happens with
10541 "sp_zonk.moving.left/right" in the classic graphics), the default
10542 (non-moving) animation shows wrong animation frames (while the
10543 moving animation, like "sp_zonk.moving.left/right", is correct,
10544 so this graphical bug never shows up with the classic graphics).
10545 For an animation with 4 frames, this causes wrong frames 0,0,1,2
10546 be drawn instead of the correct frames 0,1,2,3. This is caused by
10547 "GfxFrame[][]" being reset *twice* (in two successive frames) after
10548 an element change: First when the change delay ("ChangeDelay[][]")
10549 counter has reached zero after decrementing, then a second time in
10550 the next frame (after "GfxFrame[][]" was already incremented) when
10551 "ChangeDelay[][]" is reset to the initial delay value again.
10553 This causes frame 0 to be drawn twice, while the last frame won't
10554 be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
10556 As some animations may already be cleverly designed around this bug
10557 (at least the "Snake Bite" snake tail animation does this), it cannot
10558 simply be fixed here without breaking such existing animations.
10559 Unfortunately, it cannot easily be detected if a graphics set was
10560 designed "before" or "after" the bug was fixed. As a workaround,
10561 a new graphics set option "game.graphics_engine_version" was added
10562 to be able to specify the game's major release version for which the
10563 graphics set was designed, which can then be used to decide if the
10564 bugfix should be used (version 4 and above) or not (version 3 or
10565 below, or if no version was specified at all, as with old sets).
10567 (The wrong/fixed animation frames can be tested with the test level set
10568 "test_gfxframe" and level "000", which contains a specially prepared
10569 custom element at level position (x/y) == (11/9) which uses the zonk
10570 animation mentioned above. Using "game.graphics_engine_version: 4"
10571 fixes the wrong animation frames, showing the correct frames 0,1,2,3.
10572 This can also be seen from the debug output for this test element.)
