Subject: changed constant number of eater arrays to variable for EM game engine
X-Git-Tag: 4.2.0.2~20
X-Git-Url: https://git.artsoft.org/?p=rocksndiamonds.git;a=commitdiff_plain;h=a8c9aaa1bffd5378dbadd747866a10bd7e2faa4d

changed constant number of eater arrays to variable for EM game engine

This makes it possible to create and play levels with a number of
eater arrays other than eight (which was a contant value before)
when using the EM game engine.
