2819 Summary of bugfix/change:
2820 Fixed handling for custom elements that change when pushed by the player.
2822 Fixed/changed in version:
2826 Before 3.1.0, custom elements that "change when pushing" changed directly
2827 after the player started pushing them (until then handled in "DigField()").
2828 Since 3.1.0, these custom elements are not changed until the "pushing"
2829 move of the element is finished (now handled in "ContinueMoving()").
2831 Affected levels/tapes:
2832 The first condition is generally needed for all levels/tapes before version
2833 3.1.0, which might use the old behaviour before it was changed; known tapes
2834 that are affected are some tapes from the level set "Walpurgis Gardens" by
2836 The second condition is an exception from the above case and is needed for
2837 the special case of tapes recorded with game (not engine!) version 3.1.0 or
2838 above (including some development versions of 3.1.0), but before it was
2839 known that this change would break tapes like the above and was fixed in
2840 3.1.1, so that the changed behaviour was active although the engine version
2841 while recording maybe was before 3.1.0. There is at least one tape that is
2842 affected by this exception, which is the tape for the one-level set "Bug
2843 Machine" by Juergen Bonhagen.
2846 game.use_change_when_pushing_bug =
2847 (game.engine_version < VERSION_IDENT(3,1,0,0) &&
2849 tape.game_version >= VERSION_IDENT(3,1,0,0) &&
2850 tape.game_version < VERSION_IDENT(3,1,1,0)));
2853 Summary of bugfix/change:
2854 Fixed handling for blocking the field the player leaves when moving.
2856 Fixed/changed in version:
2860 Before 3.1.1, when "block last field when moving" was enabled, the field
2861 the player is leaving when moving was blocked for the time of the move,
2862 and was directly unblocked afterwards. This resulted in the last field
2863 being blocked for exactly one less than the number of frames of one player
2864 move. Additionally, even when blocking was disabled, the last field was
2865 blocked for exactly one frame.
2866 Since 3.1.1, due to changes in player movement handling, the last field
2867 is not blocked at all when blocking is disabled. When blocking is enabled,
2868 the last field is blocked for exactly the number of frames of one player
2869 move. Additionally, if the player is Murphy, the hero of Supaplex, the
2870 last field is blocked for exactly one more than the number of frames of

10473 GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
10475 When using an animation frame delay of 1 (this only happens with
10476 "sp_zonk.moving.left/right" in the classic graphics), the default
10477 (non-moving) animation shows wrong animation frames (while the
10478 moving animation, like "sp_zonk.moving.left/right", is correct,
10479 so this graphical bug never shows up with the classic graphics).
10480 For an animation with 4 frames, this causes wrong frames 0,0,1,2
10481 be drawn instead of the correct frames 0,1,2,3. This is caused by
10482 "GfxFrame[][]" being reset *twice* (in two successive frames) after
10483 an element change: First when the change delay ("ChangeDelay[][]")
10484 counter has reached zero after decrementing, then a second time in
10485 the next frame (after "GfxFrame[][]" was already incremented) when
10486 "ChangeDelay[][]" is reset to the initial delay value again.
10488 This causes frame 0 to be drawn twice, while the last frame won't
10489 be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
10491 As some animations may already be cleverly designed around this bug
10492 (at least the "Snake Bite" snake tail animation does this), it cannot
10493 simply be fixed here without breaking such existing animations.
10494 Unfortunately, it cannot easily be detected if a graphics set was
10495 designed "before" or "after" the bug was fixed. As a workaround,
10496 a new graphics set option "game.graphics_engine_version" was added
10497 to be able to specify the game's major release version for which the
10498 graphics set was designed, which can then be used to decide if the
10499 bugfix should be used (version 4 and above) or not (version 3 or
10500 below, or if no version was specified at all, as with old sets).
10502 (The wrong/fixed animation frames can be tested with the test level set
10503 "test_gfxframe" and level "000", which contains a specially prepared
10504 custom element at level position (x/y) == (11/9) which uses the zonk
10505 animation mentioned above. Using "game.graphics_engine_version: 4"
10506 fixes the wrong animation frames, showing the correct frames 0,1,2,3.
10507 This can also be seen from the debug output for this test element.)
