2804 Summary of bugfix/change:
2805 Fixed handling for custom elements that change when pushed by the player.
2807 Fixed/changed in version:
2811 Before 3.1.0, custom elements that "change when pushing" changed directly
2812 after the player started pushing them (until then handled in "DigField()").
2813 Since 3.1.0, these custom elements are not changed until the "pushing"
2814 move of the element is finished (now handled in "ContinueMoving()").
2816 Affected levels/tapes:
2817 The first condition is generally needed for all levels/tapes before version
2818 3.1.0, which might use the old behaviour before it was changed; known tapes
2819 that are affected are some tapes from the level set "Walpurgis Gardens" by
2821 The second condition is an exception from the above case and is needed for
2822 the special case of tapes recorded with game (not engine!) version 3.1.0 or
2823 above (including some development versions of 3.1.0), but before it was
2824 known that this change would break tapes like the above and was fixed in
2825 3.1.1, so that the changed behaviour was active although the engine version
2826 while recording maybe was before 3.1.0. There is at least one tape that is
2827 affected by this exception, which is the tape for the one-level set "Bug
2828 Machine" by Juergen Bonhagen.

2832 (game.engine_version < VERSION_IDENT(3,1,0,0) &&
2834 tape.game_version >= VERSION_IDENT(3,1,0,0) &&
2835 tape.game_version < VERSION_IDENT(3,1,1,0)));
2838 Summary of bugfix/change:
2839 Fixed handling for blocking the field the player leaves when moving.
2841 Fixed/changed in version:
2845 Before 3.1.1, when "block last field when moving" was enabled, the field
2846 the player is leaving when moving was blocked for the time of the move,
2847 and was directly unblocked afterwards. This resulted in the last field
2848 being blocked for exactly one less than the number of frames of one player
2849 move. Additionally, even when blocking was disabled, the last field was
2850 blocked for exactly one frame.
2851 Since 3.1.1, due to changes in player movement handling, the last field
2852 is not blocked at all when blocking is disabled. When blocking is enabled,
2853 the last field is blocked for exactly the number of frames of one player
2854 move. Additionally, if the player is Murphy, the hero of Supaplex, the
2855 last field is blocked for exactly one more than the number of frames of

10386 GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
10388 When using an animation frame delay of 1 (this only happens with
10389 "sp_zonk.moving.left/right" in the classic graphics), the default
10390 (non-moving) animation shows wrong animation frames (while the
10391 moving animation, like "sp_zonk.moving.left/right", is correct,
10392 so this graphical bug never shows up with the classic graphics).
10393 For an animation with 4 frames, this causes wrong frames 0,0,1,2
10394 be drawn instead of the correct frames 0,1,2,3. This is caused by
10395 "GfxFrame[][]" being reset *twice* (in two successive frames) after
10396 an element change: First when the change delay ("ChangeDelay[][]")
10397 counter has reached zero after decrementing, then a second time in
10398 the next frame (after "GfxFrame[][]" was already incremented) when
10399 "ChangeDelay[][]" is reset to the initial delay value again.
10401 This causes frame 0 to be drawn twice, while the last frame won't
10402 be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
10404 As some animations may already be cleverly designed around this bug
10405 (at least the "Snake Bite" snake tail animation does this), it cannot
10406 simply be fixed here without breaking such existing animations.
10407 Unfortunately, it cannot easily be detected if a graphics set was
10408 designed "before" or "after" the bug was fixed. As a workaround,
10409 a new graphics set option "game.graphics_engine_version" was added
10410 to be able to specify the game's major release version for which the
10411 graphics set was designed, which can then be used to decide if the
10412 bugfix should be used (version 4 and above) or not (version 3 or
10413 below, or if no version was specified at all, as with old sets).
10415 (The wrong/fixed animation frames can be tested with the test level set
10416 "test_gfxframe" and level "000", which contains a specially prepared
10417 custom element at level position (x/y) == (11/9) which uses the zonk
10418 animation mentioned above. Using "game.graphics_engine_version: 4"
10419 fixes the wrong animation frames, showing the correct frames 0,1,2,3.
10420 This can also be seen from the debug output for this test element.)
