0026 [2]byte Unknown, set only for a few roaming critters.
Pending Z-rotation is a rotation value that the critter wants to perform next. Only when this value is zero, it continues with its regular state.
Fixed forward veloctiy is used for a few critters to give them a fixed forward speed. This speed can be different than their normal speed, and even make them slower than regular.
Hastiness makes a few critter appear as if they were under the effect of a speedup-stimulant. Their actions, including their animations, are quicker.
State timeout is an indicator on how long the critter will stay in this state. Observed only in "cautious" state.
This time is reduced as long as the hacker is in the vicinity. When the time reaches zero, the critter becomes hostile.
The time value is typically quite low. A few high values like 0x0062 have been observed.
AI coordinates A and B appear to be some sort of coordinates. Changing them has no visible effect, so they may be scratch values for the AI, determining where to go next. They are used only for roaming critters.
Always 0xFF must always be set to 0xFF, otherwise the critter is immediately hostile, regardless of where it is on the map. All critters in the main game have it set to 0xFF.
Critter states
The state a critter is in is goverend by four bytes, which have meanings on their own, as well as combined effects. For simple cases, only the Primary critter state is used. This value is also the one modified by the "Set critter state" action.
A roaming critter has the Roaming critter state value set, and also needs other states to be set. Working combinations found so far are:
03 01 01 0002 01 01 00(not found in archive.dat) A critter only roams on its own if the hacker is within a radius of about 6 tiles.
A patrolling critter follows a path laid out by Critter AI Hint marker (See traps). The first marker of such a path must be referenced in the second loot object index.
The only working example of such a critter is initially docile, and has a state combination of
00 00 04 00.
The Primary critter state holds the state the critter is currently behaving in. This state is also reported by the targeting tool.
Primary Critter State (1 byte)
0x00 docile
0x01 cautious
0x02 hostile
0x03 cautious (?)
0x04 attacking
0x05 sleeping
0x06 tranquilized
0x07 confused
Various combinations of the state values can be found in the main game. While they have different effects, their pattern is not clear.
