Description

Description:

Define action performed when user clicks in map by executing command string. The code is executed on every click, until the command is

• removed via onMapSingleClick "", or
• replaced by onMapSingleClick "SomeOtherCommand(s)"

the string receives 5 (localised in scope) variables:

• _this: Anything - Params passed to onMapSingleClick
• _pos: Array - Clicked position
• _units: Array - Units which were selected (via function keys) before opening the map (may be non-functional in Arma)
• _shift: Boolean - Whether <Shift> was pressed when clicking on the map
• _alt: Boolean - Whether <Alt> was pressed when clicking on the map

In Arma 3 the code should return true only if you wish to override default engine handling of the mouse click on map (see example #4)
For older games, when click is processed, code should ultimately return true back to the engine. If false is returned, default processing by the game engine is done. Return value of any other type (including Nothing) is an error. In such case default processing by the game engine is done, and error message may be displayed.

Since Arma 3 v1.57 a stackable MissionEventHandler is available and should be used instead: MapSingleClick.
Before that, the functions BIS fnc addStackedEventHandler and BIS fnc removeStackedEventHandler should be used instead in order to keep compatibility between official and community content.

Examples

Example 1:

ArmA: Creates a soldier unit at the position clicked: onMapSingleClick "'SoldierWB' createUnit [_pos, group player]; true";

Example 2:

ArmA: Orders "grp1" to move to position clicked. Disables further map-click actions: onMapSingleClick "grp1 move _pos; onMapSingleClick ''; true";

Example 3:

OFP: In OFP single quotes cannot be used for string definition, so two double-quotes have to be used instead: onMapSingleClick "'SoldierWB' createUnit [_pos, group player]; true";

Example 4:

// The following code will disable Shift+click waypoint marker creation onMapSingleClick {_shift};

Example 5:

// Pass params to onMapSingleClick code player onMapSingleClick {hint ("Hello " + name _this)}; // Hello KK

Example 6:

// Pass params to onMapSingleClick code and disable Shift+click waypoint marker creation player onMapSingleClick "hint (""Hello "" + name this); _shift"; // Hello KK

See my Multiple OnMapSingleClick script to allow you to add multiple events to the onMapSingleClick event. Some minor editing of the scripts would be required to use them in Arma.

_units param is supposed to return what groupSelectedUnits returns. Player must be leader and some units in the group must be selected on the group bar. However selected units are connected with group orders menu, which interferes with map click. In other words, when you click on the main map, the map gets focus and group orders menu closes, deselecting any selected unit, so _units is [] pretty much all the time.
