Arma 2: Operation Arrowhead: AI FSM

AI FSM

Summary page to gather community knowledge about the exposed AI FSM and the modification possibilities.

What are they about

It seems they expose certain areas of the AI behavior outside the core engine. This means the community can modify some parts of the AI behavior this one. That said in the config space a lot of values permitted tweaking AI as well, yet on a different level.

The available FSM are about:

• Behavior while in formation.
• Behavior while in danger/from danger events.

TODO: Needs more research, testing and specific information.

What are they NOT about

• Micro AI
• Low(est) level AI behavior system

TODO: Clarify and add more details.

Where to find them

ca\characters\scripts

Where are they used

comm.fsm

No reference.

danger.fsm

class CAManBase: Man
 fsmDanger = "Ca\characters\scripts\danger.fsm";

formationC.fsm

class Civilian: CAManBase
 fsmFormation = "ca\characters\scripts\formationC.fsm";

formationCDanger.fsm

class Civilian: CAManBase
 fsmDanger = "ca\characters\scripts\formationCDanger.fsm";

formationEntity.fsm

No reference. However it is the equivalent to the config definition of:

class CAManBase: Man
 fsmFormation = "Formation";

Formation itself is also defined, for unknown reasons, in the config space rather as FSM file.

class CfgFSMs - class Formation

How to edit them

Get the FSM_Editor part of the BI Tools 2 suite. It allows you to open, study and modify the FSM files.

What do they do

comm.fsm

Makes an unit unit communicate his action:

• "Reloading! Cover me!"
• "Running!"
• "Covering!"

When are they run

comm.fsm

• Assumption*: Not at all. Seems like a test version and the actual system is integrated into the engine nowadays.

Technical details

comm.fsm

• _who = _this select 0;
• _state = _this select 1;
