2636 Summary of bugfix/change:
2637 Fixed handling for custom elements that change when pushed by the player.
2639 Fixed/changed in version:
2643 Before 3.1.0, custom elements that "change when pushing" changed directly
2644 after the player started pushing them (until then handled in "DigField()").
2645 Since 3.1.0, these custom elements are not changed until the "pushing"
2646 move of the element is finished (now handled in "ContinueMoving()").
2648 Affected levels/tapes:
2649 The first condition is generally needed for all levels/tapes before version
2650 3.1.0, which might use the old behaviour before it was changed; known tapes
2651 that are affected are some tapes from the level set "Walpurgis Gardens" by
2653 The second condition is an exception from the above case and is needed for
2654 the special case of tapes recorded with game (not engine!) version 3.1.0 or
2655 above (including some development versions of 3.1.0), but before it was
2656 known that this change would break tapes like the above and was fixed in
2657 3.1.1, so that the changed behaviour was active although the engine version
2658 while recording maybe was before 3.1.0. There is at least one tape that is
2659 affected by this exception, which is the tape for the one-level set "Bug
2660 Machine" by Juergen Bonhagen.
2663 game.use_change_when_pushing_bug =
2664 (game.engine_version < VERSION_IDENT(3,1,0,0) &&
2666 tape.game_version >= VERSION_IDENT(3,1,0,0) &&
2667 tape.game_version < VERSION_IDENT(3,1,1,0)));
2670 Summary of bugfix/change:
2671 Fixed handling for blocking the field the player leaves when moving.
2673 Fixed/changed in version:
2677 Before 3.1.1, when "block last field when moving" was enabled, the field
2678 the player is leaving when moving was blocked for the time of the move,
2679 and was directly unblocked afterwards. This resulted in the last field
2680 being blocked for exactly one less than the number of frames of one player
2681 move. Additionally, even when blocking was disabled, the last field was
2682 blocked for exactly one frame.
2683 Since 3.1.1, due to changes in player movement handling, the last field
2684 is not blocked at all when blocking is disabled. When blocking is enabled,
2685 the last field is blocked for exactly the number of frames of one player
2686 move. Additionally, if the player is Murphy, the hero of Supaplex, the
2687 last field is blocked for exactly one more than the number of frames of
