-**initJIPcompatible.sqf** is automatically started at unknown timebest guess would be when JIP player joins?+**initJIPcompatible.sqf** ​initJIPcompatible.sqf gets called from the MP mission framework (scripts in modules MP directory). A script waits until the player object ​is initialized and execs initJIPcompatible.sqf on clients (all clientseven those that were allready there at mission start as it is basically the same). Has nothing todo with init.sqf.

-====== Scripting Commands ======+[[arma2:​scripting:​zone_markers|Zone Markers]] creating script for warning zones.
  
-There'​s a lot of cool scripts (functions) available in Modules.pbo - especially under "​Functions"​ and even an multiplayer Framework in "​MP"​.+[[arma2:​scripting:​ied_usage|IED usage]] improvised explosive device usage through script.
  
-Since ArmA 2 you must first initialize a variable before you reference ​it in your scripts. In ArmA, it was not a problem, at least for conditions. +Few more [[arma2:​scripting:​comref|Scripting command ​reference]] items.
-<code cpp> +
-// this will error if myBoolean was not previously defined. +
-if (myBoolean) then { hint "​test"​ }; +
-</​code>​ +
-Usage of isNil is still valid.+

-BIS fnc locations+[[arma2:​scripting:​bis_fnc_spawngroup|BIS_fnc_spawnGroup]] how to create whole groups from CfgGroups class.
  
-Description:​ Creates or registers location logics (used in various modules, like [[arma2:​editor_modules:​alice|Ambient Civilians]], ​[[arma2:editor_modules:silvie|Ambient Civilian Vehicles]] or Warfare 2).+[[arma2:scripting:bis_fnc_findsafepos|BIS_fnc_findSafePos]] how to find safe position with open ground etc.
  
-Upon registeringfunction will set following variables into location logic'​s variable space:+Global scripts dir or common scripts dir is very useful. This feature has been known since OFPcheck out the details from [[arma:scripting#​global_scripts_dir|ArmA:​ Scripting - Global scripts dir]], as same feature works in ArmA 2.
  
-  * "​class" ​unique class of location (either BIS_loc_<​configname>​ or BIS_loc_custom_<​ID>​) +Howto create and use [[arma2:​scripting:​object-compositions|Object Compositions]] in missions.
-  * "​name"​ - name of location from config or setName commandIf none is defined, class is used +
-  * "​type"​ - config type +
-  * "​neighbors"​ - config defined neighbor locations ​+
  
-If you're registering currently existing object and some of variables above is already stored in it, it won't be replaced.+[[arma2:​scripting:​addpublicvariableeventhandler|addPublicVariableEventhandler]] examples.

- +
-===== setVariable ===== +
- +
-setVariable now has a 3rd parameter: Global. +
- +
-If you set the 3rd parameter to true, the variable will broadcast its value to every machine. +
-<code cpp> +
-_myObject setVariable ["​myVariable",​ 1, true]; +
-</​code>​ +
- +
-setVariable is now usable on any object, like groups for instance. This was not the case in ArmA. +
- +
- +
-===== uiNameSpace ===== +
- +
-Working with UI related ​scripting ​commands, is not accepted in global or private variable space, and needs to be done inside uiNameSpace by using setVariable. +
- +
-example: +
-<code cpp> +
-// set it +
-uiNameSpace setVariable ["​myVariable",​ ctrl...]+
-// use it +
-ctrl.... (uiNameSpace getVariable "​myVariable"​);​ +
-</​code>​ +
- +
- +
-===== createDiaryRecord ===== +
- +
-createDiaryRecord +
- +
-<code cpp> +
-_diary = player createDiaryRecord ["​Diary",​ ["​Technische Details",​ "​Keine"​]]; +
-</​code>​ +
- +
- +
-===== createSimpleTask ===== +
- +
-createSimpleTask +
- +
-<code cpp> +
-task1 = player createSimpleTask ["​obj1"​];​ +
-</​code>​ +
- +
- +
-===== setSimpleTaskDescription ===== +
- +
-setSimpleTaskDescription +
- +
-<code cpp> +
-task1 setSimpleTaskDescription ["​Description <marker name=""​Start"">​Start</​marker>​ posit.","​more text","​more text"​];​ +
-</​code>​ +
- +
- +
-===== setSimpleTaskDestination ===== +
- +
-setSimpleTaskDestination +
- +
-<code cpp> +
-task1 setSimpleTaskDestination markerPos "​Start";​ +
-</​code>​ +
- +
- +
-===== setTaskState ===== +
- +
-setTaskState +
- +
-<code cpp> +
-task1 setTaskState "​Created";​ +
-</​code>​ +
- +
- +
-===== setCurrentTask ===== +
- +
-setCurrentTask +
- +
-<code cpp> +
-player setCurrentTask task1; +
-</​code>​ +
- +
- +
-===== attachTo ===== +
- +
-attachTo, see also detach. +
- +
-<code cpp> +
-// Make player float exactly 2m above center of car, automatically changing vectordir + relative position as car moves. +
-player attachTo [car, [0,0,2]]; +
-detach player; +
-</​code>​ +
- +
- +
-===== diag_log ===== +
- +
-diag_log writes any variable ([_fish, _frog] or "​Hello,​ I'm starting to initialize myself"​) directly to the log, without needing to pass it via format/​str ​and without any extra text. +
- +
- +
-===== Changing nameSpace ===== +
- +
-You can change namespace inside another namespace. Note that 1 misionNamespace refers ​to the normal global scope and 1 uiNamespace is the one where you are forced to store any control/​display handles: +
-<code cpp> +
-fish = "​Frog!";​ +
- +
-with uiNamespace do +
-+
- // Do some stuff with dialogs here. +
- +
- with missionNamespace do +
-+
- hint fish; // This sees the "​regular"​ mission namespace. +
- }; +
- // Do some more stuff with dialogs here. +
-}; +
-</​code>​ +
- +
-I have no idea what the purpose of 1 parsingNamespace is. +
- +
- +
-===== Access nameSpace ===== +
- +
-The command 1 with gives you a much nicer way to access namespaces and is especially cleaner when making multiple accesses: +
-<code cpp> +
-with uiNameSpace do +
-+
- // Any globals in this block are taken from uiNameSpace. +
- // Any locals are normal locals from current scope. +
- (fishDisplay displayCtrl 102) ctrlSetText _frog; +
- piesControl ctrlSetText _pies; +
- cheeseControl ctrlSetText _cheese; +
-}; +
-</​code>​ +
- +
-Rather than: +
-<code cpp> +
-((uiNameSpace getVariable "​fishDisplay"​) displayCtrl 102) ctrlSetText _frog; +
-(uiNameSpace getVariable "​piesControl"​) ctrlSetText _pies; +
-(uiNameSpace getVariable "​cheeseControl"​) ctrlSetText _cheese; +
-</​code>​ +
- +
- +
-===== fromEditor ===== +
- +

- +
-Syntax: +
- +
-fromEditor teamMember  +
- +
-Parameters:​ +
- +
-teamMember: Team Member +
- +
-Return Value: +
- +
-Boolean  +
- +
-Example: +
-<code cpp> +
-_fromEditor = fromEditor _member; +
-</​code>​ +
- +
- +
-===== addTeamMember ===== +
- +
-Add given member to given team.  +
- +
-Syntax: +
- +
-team addTeamMember member  +
- +
-Parameters:​ +
- +
-team: Team_Member\\ +
-member: Team_Member +
- +
-Return Value: +
- +
-Nothing  +
- +
-Example 1: +
-<code cpp> +
-_team addTeamMember _teamMember;​ +
-</​code>​ +
- +
- +
-===== copyWaypoints ===== +
- +
-Copy the chain of waypoints from source to target group. The target group will start to process waypoints from the first one.  +
- +
-Syntax: +
- +
-groupTo copyWaypoints groupFrom  +
- +
-Parameters:​ +
- +
-groupTo: Group\\ +
-groupFrom: Group +
- +
-Return Value: +
- +
-Nothing +
- +
- +
-===== execFSM ===== +
- +
-Execute the scripted FSM. The FSM file is first searched in the mission folder, then in the campaign scripts folder and finally in the global scripts folder. Returns the FSM handler or 0 when failed.  +
- +
-Syntax: +
- +
-execFSM filename  +
- +
-Parameters:​ +
- +
-filename: - +
- +
-Return Value: +
- +
-Number  +
- +
-Example 1: +
-<code cpp> +
-execFSM "​test.fsm";​ +
-</​code>​ +
- +
-Example 2:\\ +
-execFSM: +
-<code cpp> +
-hndl = [player] execFSM "​group_follow.fsm";​ +
-</​code?​ +
- +
-execVM: +
-<code cpp> +
-hndl = player execVM "​group_follow.sqf";​ +
-</​code>​ +
- +
- +
-====== taskHint.sqf ====== +
- +
-How to make task hints +
- +
-taskHint is relatively useless itself (because it requires too much effort), but there is a script that makes it easier to use. So instead of executing a hint, do this: +
-<code cpp> +
-[objNull, objNull, tskExample1,​ "​SUCCEEDED"​] execVM "​CA\Modules\MP\data\scriptCommands\taskHint.sqf";​ +
-</​code>​ +
- +
-The first 2 arguments are useless so i just send objNull, the 3rd is the task that you've created, and the 4th is the status. +
- +
-Supported task states: "​CREATED",​ "​CURRENT",​ "​CANCELED",​ "​SUCCEEDED"​ and "​FAILED"​. +
- +
-  * This command does not set the state of the task, so you still need to do this command, and the setTaskState command in your trigger. +
-  * It creates the hint in the middle of the screen, not at the right side (this means that taskHint and hint can be used at the same time).+
