Bash functions for moving
This function library contains bash shell functions to move
a player.
Though it had been tested with the busybox ash shell, some functions might only work correctly in bash ( or the other way around ).
Most noticeable function should be _check_for_space() that attempts to probe,
if a tile a character is about to step on, is actually not some kind of wall.
The code had changed between v.1.10.0 and 1.12.0 of the client,
so older clients would likely need to use the _check_for_space_old_client() function.
The functions use code from
650 lines of code:
