2848 Summary of bugfix/change:
2849 Fixed handling for custom elements that change when pushed by the player.
2851 Fixed/changed in version:
2855 Before 3.1.0, custom elements that "change when pushing" changed directly
2856 after the player started pushing them (until then handled in "DigField()").
2857 Since 3.1.0, these custom elements are not changed until the "pushing"
2858 move of the element is finished (now handled in "ContinueMoving()").
2860 Affected levels/tapes:
2861 The first condition is generally needed for all levels/tapes before version
2862 3.1.0, which might use the old behaviour before it was changed; known tapes
2863 that are affected are some tapes from the level set "Walpurgis Gardens" by
2865 The second condition is an exception from the above case and is needed for
2866 the special case of tapes recorded with game (not engine!) version 3.1.0 or
2867 above (including some development versions of 3.1.0), but before it was
2868 known that this change would break tapes like the above and was fixed in
2869 3.1.1, so that the changed behaviour was active although the engine version
2870 while recording maybe was before 3.1.0. There is at least one tape that is
2871 affected by this exception, which is the tape for the one-level set "Bug
2872 Machine" by Juergen Bonhagen.
2875 game.use_change_when_pushing_bug =
2876 (game.engine_version < VERSION_IDENT(3,1,0,0) &&
2878 tape.game_version >= VERSION_IDENT(3,1,0,0) &&
2879 tape.game_version < VERSION_IDENT(3,1,1,0)));
2882 Summary of bugfix/change:
2883 Fixed handling for blocking the field the player leaves when moving.
2885 Fixed/changed in version:
2889 Before 3.1.1, when "block last field when moving" was enabled, the field
2890 the player is leaving when moving was blocked for the time of the move,
2891 and was directly unblocked afterwards. This resulted in the last field
2892 being blocked for exactly one less than the number of frames of one player
2893 move. Additionally, even when blocking was disabled, the last field was
2894 blocked for exactly one frame.
2895 Since 3.1.1, due to changes in player movement handling, the last field
2896 is not blocked at all when blocking is disabled. When blocking is enabled,
2897 the last field is blocked for exactly the number of frames of one player
2898 move. Additionally, if the player is Murphy, the hero of Supaplex, the
2899 last field is blocked for exactly one more than the number of frames of

10557 GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
10559 When using an animation frame delay of 1 (this only happens with
10560 "sp_zonk.moving.left/right" in the classic graphics), the default
10561 (non-moving) animation shows wrong animation frames (while the
10562 moving animation, like "sp_zonk.moving.left/right", is correct,
10563 so this graphical bug never shows up with the classic graphics).
10564 For an animation with 4 frames, this causes wrong frames 0,0,1,2
10565 be drawn instead of the correct frames 0,1,2,3. This is caused by
10566 "GfxFrame[][]" being reset *twice* (in two successive frames) after
10567 an element change: First when the change delay ("ChangeDelay[][]")
10568 counter has reached zero after decrementing, then a second time in
10569 the next frame (after "GfxFrame[][]" was already incremented) when
10570 "ChangeDelay[][]" is reset to the initial delay value again.
10572 This causes frame 0 to be drawn twice, while the last frame won't
10573 be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
10575 As some animations may already be cleverly designed around this bug
10576 (at least the "Snake Bite" snake tail animation does this), it cannot
10577 simply be fixed here without breaking such existing animations.
10578 Unfortunately, it cannot easily be detected if a graphics set was
10579 designed "before" or "after" the bug was fixed. As a workaround,
10580 a new graphics set option "game.graphics_engine_version" was added
10581 to be able to specify the game's major release version for which the
10582 graphics set was designed, which can then be used to decide if the
10583 bugfix should be used (version 4 and above) or not (version 3 or
10584 below, or if no version was specified at all, as with old sets).
10586 (The wrong/fixed animation frames can be tested with the test level set
10587 "test_gfxframe" and level "000", which contains a specially prepared
10588 custom element at level position (x/y) == (11/9) which uses the zonk
10589 animation mentioned above. Using "game.graphics_engine_version: 4"
10590 fixes the wrong animation frames, showing the correct frames 0,1,2,3.
10591 This can also be seen from the debug output for this test element.)
