Description

Description:

Executes scripted FSM and returns the FSM handle or 0 when failed. The FSM file is first searched in the mission folder, then in the campaign scripts folder and finally in the global scripts folder. Argument (if any) are available in _this variable inside FSM. In Arma 3 FSM handle is also available in _thisFSM variable.

The scripted FSM structure normally consists of one init state, one or more conditional links, one or more normal states and one or more final states. Each state has init and precondition section, while each conditional link has precondition, condition and action sections. The order of execution is:

• State: init->precondition
• Conditional link (condition is true): precondition->condition->action
• Conditional link (condition is false): precondition->condition

Scripted FSMs are added into the scheduler just like exec scripts, execVM scripts and spawn scripts. While the code placed into any of the sections of FSM cannot be suspended (canSuspend is false) the FSM itself is suspended every simulation between state's init and state's precondition (exception is the init state). Normally the difference between state's init and precondition is 1 frame but if the scheduler is busy it can take longer. This is the only place where scripted FSM is suspended/resumed.

To see what FSMs are currently in the scheduler, use diag_activeMissionFSMs command

Syntax

Syntax:

arguments execFSM filename

Parameters:

arguments: Anything - Arguments accessible as _this in the FSM

filename: String - file with FSM code

Return Value:

Number - FSM handle, can be used to determine (via completedFSM) when the execed FSM has finished. In Arma 3, the handle is also available inside the FSM in _thisFSM variable.

Alternative Syntax

Syntax:

execFSM filename

Parameters:

filename: String - file with FSM code String

Return Value:

Number - FSM handle, can be used to determine (via completedFSM) when the execed FSM has finished. In Arma 3, the handle is also available inside the FSM in _thisFSM variable.

Examples

Example 1:

_id = player execFSM "test.fsm";

Example 2:

_handle = [_a, _b, _c] execFSM "test.fsm";

Example 3:

_handle = execFSM "test.fsm";
