**********
CHANGE MOTION:
**********

This section relates to the little known action property of whether a sprite can change its
horizontal and vertical motion.

Every aniamtion of every sprite in Keen has two variables set aside telling the game whether
it can change it's h or v motion. This is not related to movement in any way; a Bounder can
bound left, right, up and down without using these parameters. What these control is if the
sprite clings to the ground or wall, that is, can it crawl up and down hills or walls?

The Slug is a good example; it doesn't fall, but clings to the ground; it can crawl up hills,
but will then crawl down them again. It there for has a 'Cling to ground' value of 1. If
it did not have this, it would crawl up hills, but then not be able to crawl down! (For
Slugs the situation is worse, without this they think they are floating in air and do
nothing but spin around!) The 'cling to walls' value is needed by some 'in the air' sprites
to make sure they don't accidentally clip into walls. (This was done for the convenience
of the programmers.)

As stated, there are two values for these variables; 0 or 1. Most sprites use 0, but ALL
crawling (And some sitting) sprites must cling to the gound, or unhapiness may result. (As
a rule, if a crawling sprite doesn't cling, when it comes to an edge, it'll just float right
along in the air. This can be useful of course.)

The main use of this section will be if you change a sprite to crawl on the ground, though
other uses may be possible.
