2.) How sprites act when created
*****************************************


The first set of patches here control how a sprite acts when  it is created; for example, 
when a Yorp is first created it immediately acesses the Yorp code, and becomes a one eyed 
green thing. Switching its value with a Garg will make it use the Garg behaviours and sprites, 
but of course it will still push Keen, and show a stunned Yorp when Keen stomps it. Following 
this are a few patches allowing more than one sprite to be spawned at once.


Some special notes on behaviour here should be noted; 

The behaviour 'Do nothing' is used for dead sprites and means Keen can't shoot or interact with 
them. When a created sprite is given this value, it will just sit there; not animating or interacting 
in any way. 

The behaviour $FC $75 is used for shocked sprites, and ensures they animate and fall down. If 
changed to $60 $33 the shocked sprite will just sit there; if it is patched to make a live sprite,
when shot the sprite will *immediately* become another one, whereas unlike patching the dead 
sprite property [see section 5.)] The shocked and dead sprite properties are thus both different 
and independent. If you make a sprite transform into another sprite, you must patch the dead sprite 
behaviour as well, otherwise the newly created sprite will be immortal

The behaviour $E8 $47, as used by Zap/Zot sprites is complex; there are at least five different 
patches for the Zap/zot sprites because instead of one sprite, the zap/zot is actually seven. 
The first sprite is almost never used, the second appears only once [it is the first Zap/zot in 
the level] and the third is spawned when a shot hits a wall [Patching this makes a zap/zot that 
sticks to walls, but can be destroyed by shooting it.] The fourth appears when a shot hits a sprite 
[including other zap/zots, so patching both this and the third make all Zap/zots in the level 
indestructable] The rest aren't really used, but will all need to be patched if you want to be 
absolutely sure of changing the zap/zot properties.

The Tantalus ray behaviour affects what happens ON THE REPLACED TILES TO THE ZAP/ZOT SPRITESUsually 
this is simply appear then dissapear; but if say it's set to 'act like a vorticon' EVERY replaced 
tile will also spawn a Vorticon; or a total of 14 Vorticons will be created, as well as the tiles 
being replaced, unless you patch the Tantalus ray.

Giving a sprite Keen's property will make it copy Keen exactly, except for getting stunned, killed
or having the screen follow it. In other words it will ape keen exactly, usually dying when Keen 
presses shoot.

The Zap/zots are complex; only 3 and 6 are well defined, but the remaining four will ALL need to 
be patched before ALL the Zap/zots change behaviour. It is not wise to make the Zap/zots hang 
around or they'll build up, especially near robots.

It is possible to make Scrubs stop moving when they hit a wall, floor, ceiling, etc if you patch
their 'hit wall, ceiling...' behaviours to 'keen moving along floor, ceiling, etc' They will also
fall if they cannot grab a wall, floor, etc. That usually happens either if they encounter a tile
with less than four 'blocking' sides [such as a 1 way platform] or if Keen snatches the point item
tile they are walking on away.

Replacing the 'fall down animating' behaviour of dead sprites makes the sprite spawn a living
sprite when shot. This sprite is immortal.

The patches allowing more than one sprite to be spawned at once work by altering game code so that 
the game doesn't stop after making one sprite, but moves on to the next one as well. This allows 
two [or more] sprites to be made from one sprite event. You can make three [or four, or five] 
sprites at once if you use two patches that follow one another [For example patch 2 and patch 3] 
Note that if a Vortikid also spawns an Elite, an Elite will NOT spawn a Vortikid. These patches 
are useful for example if you make a vorticon spawn a Vortikid when it dies, it can then spawn 
both a Vortikid AND an Elite [1 sprite splits into 2]
