| '''FSM: ( Fine State Machine )'''
| |
|
| |
|
| In ArmA 2 we have 2 different .fsm which are used to set how A.I. should behave in combat.
| |
|
| |
| 1. NativeFSM ( CACharacters\CfgFSMs.hpp )<br/>
| |
| 2. ScriptedFSM ( CACharacters\Scripts\Danger.fsm )
| |
|
| |
| Bouth FSMs are initialized in the "CACharacter" >> "CfgVehicles" >> "CAManBase".
| |
|
| |
| The '''NativeFSM''' is used to control the general behaviour of A.I. units in combat.<br/>
| |
| It will choose if A.I. should go to cover or attack a known enemy.<br/>
| |
| If A.I. should reload while in cover or if A.I. should look for any other ( may better ) cover.<br/>
| |
| It also let you choose if A.I. should provide cover or if they should try fighting on their own.<br/>
| |
|
| |
| The '''ScriptedFSM''' is used to control the general behaviour of A.I. in situations which are dangerous.<br/>
| |
| This is something like a Event Handler which is triggering after a specific event happend.<br/>
| |
| The ScriptedFSM Conditions:<br/>
| |
|
| |
| *'''Detect Enemys:''' This will trigger every time A.I. has detected a enemy unit.
| |
|
| |
| *'''Detect Weapon fire:''' This will trigger every time a unit has fired a weapon.<br/>
| |
| ''Note:'' The A.I. which should detect weapon fire must have the chance to know more then 0 about the unit which has fired the weapon.
| |
|
| |
| *'''Detect Enemys Near:''' This will trigger every time A.I. has detected a enemy unit which is very close.
| |
|
| |
| *'''Detect Explosions:''' This will trigger every time after something is exploded? ( Havent seen this so far... )
| |
|
| |
| *'''Detect Dead Bodys:''' This will trigger every time A.I. has detected a dead body. Note: Exploded vehicles are triggered here too.
| |
|
| |
| *'''Detect Stop Fire:''' This will trigger randomly and make A.I. to stop moving for 4 - 8 sec.<br/>
| |
|
| |
| If multiple conditions match then they will be triggered given to the priority set in the event.

| ====Global Array System====
| |
|
| |
| Each "[[Variables|Global Variable]]" will be stored in the memory.
| |
| This means many "[[Variables|Global Variable]]" will need much memory space.
| |
| You can reduce the resources used from "[[Variables|Global Variable]]" by using a "Gloabal Array" which stores all needed values instead of creating a new "[[Variables|Global Variable]]" for each value.
| |
|
| |
|
| |
| '''Default:''' ( Bad )
| |
| <code><nowiki>
| |
| Global_Bool = True;
| |
|
| |
| Global_Number = 30;
| |
|
| |
| Global_Distance = 500;
| |
|
| |
| Global_Array = [];
| |
| </nowiki></code>
| |
| Now we have created 4 different "[[Variables|Global Variable]]" which will need 3x more memory like the optimized way.
| |
|
| |
|
| |
| Examples:
| |
| <code><nowiki>
| |
| if (Global_Bool) then
| |
| {
| |
| Global_Bool = False;
| |
|
| |
| .......
| |
| };
| |
| </nowiki></code>
| |
|
| |
| <code><nowiki>
| |
| if (count _array < Global_Number) then
| |
| {
| |
| .......
| |
| };
| |
| </nowiki></code>
| |
|
| |
| <code><nowiki>
| |
| if (player distance _object < Global_Distance) then
| |
| {
| |
| .......
| |
| };
| |
| </nowiki></code>
| |
|
| |
| <code><nowiki>
| |
| if !(_object in Global_Array) then
| |
| {
| |
| Global_Array = Global_Array + [_object];
| |
|
| |
| .......
| |
| }
| |
| else
| |
| {
| |
| Global_Array = Global_Array - [_object];
| |
|
| |
| .......
| |
| };
| |
| </nowiki></code>
| |
|
| |
|
| |
| '''Optimized:''' ( Good )
| |
| <code><nowiki>
| |
| Global_System = [True, 30, 500, [] ];
| |
| </nowiki></code>
| |
| Now we have stored all values in only '''1''' "Global Variable" called "Global_System".
| |
|
| |
| You can check / select the needed value by using (Global_System select Index).
| |
| Index is the position ( number ) in which the given value was stored.
| |
|
| |
|
| |
| Select the Bool: True
| |
| <code><nowiki>
| |
| (Global_System select 0)
| |
| </nowiki></code>
| |
|
| |
| Select the Number: 30
| |
| <code><nowiki>
| |
| (Global_System select 1)
| |
| </nowiki></code>
| |
|
| |
| Select the Array: []
| |
| <code><nowiki>
| |
| (Global_System select 3)
| |
| </nowiki></code>
| |
|
| |
|
| |
| Examples:
| |
| <code><nowiki>
| |
| if (Global_System select 0) then
| |
| {
| |
| Global_System set [0, False];
| |
|
| |
| .......
| |
| };
| |
| </nowiki></code>
| |
|
| |
| <code><nowiki>
| |
| if (count _array < (Global_System select 1) ) then
| |
| {
| |
| .......
| |
| };
| |
| </nowiki></code>
| |
|
| |
| <code><nowiki>
| |
| if (player distance _object < (Global_System select 2) ) then
| |
| {
| |
| .......
| |
| };
| |
| </nowiki></code>
| |
|
| |
| <code><nowiki>
| |
| if !(_object in (Global_System select 3) ) then
| |
| {
| |
| Global_System set [3, (Global_System select 3) + [_object] ];
| |
|
| |
| .......
| |
| }
| |
| else
| |
| {
| |
| Global_System set [3, (Global_System select 3) - [_object] ];
| |
|
| |
| .......
| |
| };
| |
| </nowiki></code>
