There is a small chance that other plugin cancel these events. Since the
server ignores event.setFrom for cancelled events and also won't fire a
teleport event, this remains a problematic case.
Represents the first "simplistic" approach to block change tracking,
only attempting to make vertical push/pull work.
It seems that we need to add on-ground checking accounting for piston
moves as well, otherwise anything with pistons retracting will lead to
survivalfly violations. Pistons extending and retracting may also
randomly move around players, including dragging them into the piston
block with the bounding box (not center of player).
In order to make on-ground work, we might need to check in another
place, possibly check where resetFrom an resetTo are set. Performance
questions might remain, there might also be a slight redesign necessary,
in order to run some sub-routines more side-effect free, to check
several branches, including after-failure checking.
* Default order: order of first put (first put is first on iteration).
* Fix order being done right for all cases.
* Fix linking.
* Override clear.
* Add more tests.
* Below 1.7 allow ground-to-ground hop with moderate speed. Might be
there is more speed possible, shortly tested on 1.6.4.
* From 1.7.10 on, hitting the jump envelope or having the head
obstructed is demanded.
* The GROUND_HEIGHT flag indicates, that players are on ground (and can
walk on) from getGroundMinHeight on, once a block collides. Thus an
extra case for isPassableWorkaround is necessary.
* Set GROUND_HEIGHT for ENDER_PORTAL_FRAME, return the minimal height of
the ENDER_PORTAL_FRAME block for getGroundMinHeight. (Also add XZ100,
just to be sure.)
This breaks testing for UNKNOWN_VERSION, if that is used externally.
Access methods are added for testing for unknown versions.
