Arma: GUI Configuration

Dialogs are one way to provide custom graphical user interface in your missions and allow interaction with the player aswell as they are able to run code. They are defined as classes in the missionConfigFile (description.ext), campaignConfigFile (Campaign Description.ext) or configFile (config.cpp).

Terminology

GUI

Graphical User Interface which lets the user interact with the software through graphical controls like buttons, lists and so on.

UI

User Interface which lets the user interact with the software through a console application

IGUI

Integrated Graphical User Interface, usually used when talking about vanilla menus in Arma 3.

User Interface Types

Dialog

• Can be created upon an existing display. Parent display will be hidden.

• • Player movement is blocked by dialog
  • Commands: createDialog, closeDialog, allControls, dialog

Display

• Can be created upon an existing display. Parent display will be hidden.
• Player movement is not blocked by display, if it hasn't been blocked by its parent display already.
  • Commands: createDisplay, closeDisplay, allControls, allDisplays

ⓘ

Generally speaking, dialogs and displays are identical. They are only differentiated by the way they are created (createDisplay, createDialog).

HUD

• Is created in a new, or already existing layer. The user can not interact with it. Usually used to show information, like stamina, ammunition and so on.
  • Commands: allCutLayers, titleRsc, cutText, cutObj, cutFadeOut, setTitleEffect, allActiveTitleEffects

ⓘ

Some of the commands have different effects. Please check the command's biki page for detailed information.

Display and Dialog

Displays and dialogs are defined in the config file. They are usually used to simplify user interactions, through controls like buttons, list boxes and so on.

Properties

Name	Type	Remark
idd	Integer	The unique ID number of this dialog. Used with findDisplay to find the display. Can be -1 if no access is required from within a script.
access	Integer	0 - ReadAndWrite - this is the default case where properties can still be added or overridden. 1 - ReadAndCreate - this only allows creating new properties. 2 - ReadOnly - this does not allow to do anything in deriving classes. 3 - ReadOnlyVerified - this does not allow to do anything either in deriving classes, and a CRC check will be performed.
movingEnable	Boolean	Specifies whether the dialog can be moved or not (if enabled one of the dialogs controls should have the moving property set to 1 so it becomes the "handle" the dialog can be moved with). Doesn't seem to matter in Arma 3
enableSimulation	Boolean	Specifies whether the game continues while the dialog is shown or not.
onLoad	String	Expression executed when the dialog is opened. See User Interface Event Handlers
onUnload	String	Expression executed when the dialog is closed. See User Interface Event Handlers
controlsBackground	Array or class	Contains class names of all background controls associated to this dialog. The sequence in which the controls are listed will decide their z-index (i.e. the last ones will on top of the first ones).
controls	Array or class	Contains class names of all foreground controls associated to this dialog.
objects	Array or class	List of all DialogControls-Objects type controls

• Example Config:

class DefaultDialog
{
	idd = -1;
	access = 0;
	movingEnable = true;
	onLoad = "hint str _this";
	onUnload  = "hint str _this";
	enableSimulation = false;
	class ControlsBackground
	{
		//Background controls;
	};
	class Controls
	{
		//Controls;
	};
	class Objects
	{
		//Objects
	};
};

Opening a display or dialog

There are two ways of creating a display or dialog. One can either use createDialog or createDisplay command.

Closing a display or dialog

There are several ways how a dialog can be closed.

• by pressing the Escape-key
• by using closeDialog
• by using closeDisplay
• when the user presses a button with IDC 0, 1 or 2

HUDs

HUDs are define in the class RscTitles, unlike displays or dialogs which are root classes in the config file. Additionally, their properties are different.

Properties

Name	Type	Remark
idd	Integer	The unique ID number of this HUD. Used with findDisplay to find the display. Can be -1 if no access is required from within a script.
fadeIn	Integer	Duration of fade in effect when opening in seconds.
fadeOut	Integer	Duration of fade out effect when closing in seconds.
duration	Integer	Duration the HUD is displayed after opening in seconds. Use a very large number to have it always open.
onLoad	String	Expression executed when the dialog is opened. See User Interface Event Handlers
onUnload	String	Expression executed when the dialog is closed. See User Interface Event Handlers
controls	Array	Contains class names of all foreground controls associated to this dialog.

• Example Config:

#include "\a3\ui_f\hpp\definecommongrids.inc"
class RscTitles
{
	class RscInfoText
	{
		idd = 3100;
		fadein = 0;
		fadeout = 0;
		duration = 1e+011;
		onLoad = "uinamespace setVariable ['BIS_InfoText',_this select 0]";
		onUnLoad = "uinamespace setVariable ['BIS_InfoText', nil]";
		class Controls
		{
			class InfoText
			{
				idc = 3101;
				style = "0x01 + 0x10 + 0x200 + 0x100";
				font = "RobotoCondensedBold";
				x = "(profileNamespace getVariable [""IGUI_GRID_MISSION_X"", (safezoneX + safezoneW - 21 * (GUI_GRID_WAbs / 40))])";
				y = "(profileNamespace getVariable [""IGUI_GRID_MISSION_Y"", (safezoneY + safezoneH - 10.5 * (GUI_GRID_HAbs / 25))])";
				w = "20 * (GUI_GRID_WAbs / 40)";
				h = "5 * ((GUI_GRID_WAbs / 1.2) / 25)";
				colorText[] = {1,1,1,1};
				colorBackground[] = {0,0,0,0};
				text = "";
				lineSpacing = 1;
				sizeEx = 0.045;
				fixedWidth = 1;
				deletable = 0;
				fade = 0;
				access = 0;
				type = 0;
				shadow = 1;
				colorShadow[] = {0,0,0,0.5};
				tooltipColorText[] = {1,1,1,1};
				tooltipColorBox[] = {1,1,1,1};
				tooltipColorShade[] = {0,0,0,0.65};
			};
		};
	};
};

Controls

Controls are used to allow the player to interact with the GUI. Controls range from simple rectangles to 3D objects. Like dialogs, displays and HUDs, controls can have a unique ID to access them from within scripts. The classname of controls have to be unique.

What properties a control needs is defined by its type property. However most controls share a set of properties described in the following sections. For control specific properties visit the corresponding pages.

Common Properties

Name	Type	Remark
idc	Integer	The unique ID number of this control. Can be -1 if you don't require access to the control itself from within a script
moving	Boolean	Whether the dialog will be moved if this control is dragged (may require "movingEnable" to be 1 in the dialog. In Arma 3 works regardless). Another way of allowing moving of the dialog is to have control of style ST_TITLE_BAR
type	Integer	See Control Types
style	Integer	See Control Styles. style = "0x400+0x02+0x10";
x/y/w/h	Number	The position and size of the control in fractions of screen size.
sizeEx	Number	The font size of text in fractions of screen size. Behaves similar to h property. For some controls it is named size.
font	String	The font to use. See the list of available fonts for possible values.
colorText	Array	Text color
colorBackground	Array	Background color
text	String	The text or picture to display.
shadow	Integer	Can be applied to most controls (0 = no shadow, 1 = drop shadow with soft edges, 2 = stroke).
tooltip	String	Text to display in a tooltip when control is moused over. A tooltip can be added to any control type except CT_STATIC and CT_STRUCTURED_TEXT. Note: As of -wrong parameter ("a3") defined!-[[:Category:Introduced with a3 version 1.48|1.48]], most controls now support tooltips. A linebreak can be created by adding \n.
tooltipColorShade	Array	Tooltip background color
tooltipColorText	Array	Tooltip text color
tooltipColorBox	Array	Tooltip border color

A property to enable or disable a control does not exist (because of implementation issues). However, there is a simple workaround based on the onLoad UI Event Handler that can be used to disable a control in the config:

onLoad = "(_this # 0) ctrlEnable false;";

Attributes Class

Name	Type	Remark
font	String	Available Fonts
color	HTML color	HTML Color Codes
align	String	"center", "left", "right"
shadow	Integer	0 = no shadow, 1 = drop shadow with soft edges, 2 = stroke

Control Types

The type property of controls defines what type of control they are. For example an edit box has the type 2. There is an ingame dialog with examples of how the control types look and act like: createDialog "RscTestControlTypes";

Control Styles

To further customize controls there are several different styles for each control type available.

To get an idea of how the styles look like you can create the following dialog: createDialog "RscTestControlStyles";

⚠

Note that drawing of vertical text is not supported and any attempt to use ST_UP, ST_DOWN, ST_VCENTER is likely to result in the following .rpt spam:
Obsolete, sizeH and sizeW calculation missing
In addition, ST_UP, ST_DOWN, ST_VCENTER are stand alone styles and should not be mixed with any other styles

Define	Decimal	Hexadecimal	Remark
ST_LEFT	0	0x00	Default, text left aligned
ST_RIGHT	1	0x01	Modifier, adding this to another style will force text to be aligned to the right
ST_CENTER	2	0x02	Modifier, adding this to another style will force text to be centered
ST_DOWN	4	0x04	Vertical text alignment (See the note above)
ST_UP	8	0x08	Vertical text alignment (See the note above)
ST_VCENTER	12	0x0C	Vertical text alignment, same as ST_DOWN + ST_UP (See the note above)
ST_SINGLE	0	0x00	Plain single line box without a border
ST_MULTI	16	0x10	Plain multiple line box with a slight border. To remove border add 512 (+ ST_NO_RECT) to the style (style 528, 529 and 530 are therefore border-less). Additional parameter lineSpacing is required for this style. lineSpacing = 1; is normal line spacing. Any \n character in the text string will be interpreted as new line.
ST_TITLE_BAR	32	0x20	Plain single line box with semi-transparent background and somewhat embossed border. When this style is used, the dialog containing control becomes draggable by this control
ST_PICTURE	48	0x30	Border-less picture box. Text string is treated as a path to a texture. Alignment has no effect. The texture is stretched to fit the box by default. To force original aspect ratio add 2048 (+ ST_KEEP_ASPECT_RATIO) to the style. Background is ignored, colorText controls texture colour and opacity
ST_FRAME	64	0x40	Legend like frame without background with text showing over the frame edge. Alignment has no effect. colorText defines both text and frame colour
ST_BACKGROUND	80	0x50	Single line box with always black opaque background and thick raised beveled border
ST_GROUP_BOX	96	0x60	Single line box with delicate semi-transparent background and slight border. Only text colour can be controlled
ST_GROUP_BOX2	112	0x70	Plain single line box, same as ST_SINGLE, only with a slight border similar to ST_MULTI box border
ST_HUD_BACKGROUND	128	0x80	Sets special texture for corners. It was used for rounded corners in OFP, Arma and Arma 2. In Arma 3, square corners are used everywhere, so the texture is adapted to the unified style, but the technology is not removed. In Arma 3 it looks the same as normal ST_SINGLE. Corner textures are defined in configFile >> "CfgInGameUI" >> "imageCornerElement" (can be set only globally for the whole game, not per control)”
ST_TILE_PICTURE	144	0x90	The picture is tiled according to tileH and tileW values. To force tiled picture to keep aspect ratio of original image, add 2048 (+ ST_KEEP_ASPECT_RATIO) to the style.
ST_WITH_RECT	160	0xA0	Single line box frame, similar to ST_FRAME box. The text however is displayed inside the frame. Frame and text colour are set with colorText
ST_LINE	176	0xB0	Diagonal line going from left top corner to bottom right corner. To control line direction, width w and height h parameters of the box could be negative. Line and text colour are set with colorText
ST_UPPERCASE	192	0xC0	Forces control text to upper case
ST_LOWERCASE	208	0xD0	Forces control text to lower case
ST_ADDITIONAL_INFO	3840	0x0F00	ST_SHADOW + ST_NO_RECT + SL_HORZ + ST_KEEP_ASPECT_RATIO
ST_SHADOW	256	0x0100
ST_NO_RECT	512	0x0200	This style works for CT_STATIC in conjunction with ST_MULTI
ST_KEEP_ASPECT_RATIO	2048	0x0800	When used with image or texture, stops it from stretching to fit the control
ST_TITLE	34	0x22	ST_TITLE_BAR + ST_CENTER

Positioning

A detailed description of how you can achieve proper GUI placement can be found on the Arma 3 GUI Coordinates page.

Inheritance

Using inheritance can reduce your dialog class definitions significantly by standardising common attributes in base classes and just changing unique attributes in derived classes. There is no need to redeclare all attributes for each class definition.

ⓘ

Using inheritance can also make your GUI config hard to read for others.

• Example Config:

class RscText // Base definition used for inheritance
{
	type = CT_STATIC;
	idc = -1;
	style = ST_LEFT;
	colorBackground[] = {0, 0, 0, 1};
	colorText[] = {1, 1, 1, 1};
	font = FontM;
	sizeEx = 0.04;
	h = 0.04;
	text = "";
};

class My_BlueText : RscText // My_BlueText inherits all attributes from RscText defined above, thus only x,w & colorText need to be changed
{
	colorText[] = {0, 0, 1, 1};
	x = 0.1;
	w = 0.4;
};

class My_Dialog
{
	//…

	controls[] = {
		My_Text_1,
		My_Text_2
	};

	class My_Text_1 : My_BlueText // My_Text_1 inherits all attribute from My_BlueText, therefore only text & y attributes have to be changed
	{
		text = "Line 1";
		y = 0.2;
	};

	class My_Text_2 : My_BlueText
	{
		text = "Line 2";
		y = 0.25;
	};
};

Preprocessor instructions

Note that you can also add your own preprocessor instructions for commonly used data, eg. for colors, to save yourself the hassle of writing it in several different places and then adapt each of them if you want to change them afterwards (especially if class inheritance isn't applicable). Also it can make your code look more readable sometimes.

• Example Config:

#define COLOR_LIGHTBROWN { 0.776, 0.749, 0.658, 1 }
#define COLOR_HALF_BLACK { 0, 0, 0, 0.5 }
#define COLOR_TRANSPARENT { 0, 0, 0, 0 }

class MyDialog
{
	idd = -1;
	movingEnable = 1;
	objects[] = {};
	controlsBackground[] = { MyDialogBackground };
	controls[] = { MyDialogText };

	class MyDialogBackground : RscText
	{
		colorBackground[] = COLOR_HALF_BLACK;
		x = 0.7;  y = 0.1;
		w = 0.25; h = 0.15;
	};

	class MyDialogText : RscText
	{
		style = ST_MULTI;
		colorBackground[] = COLOR_TRANSPARENT;
		colorText[] = COLOR_LIGHTBROWN;
		text = "No power in the 'Verse can stop me.";
		lineSpacing = 1;
		x = 0.71; y = 0.11;
		w = 0.23; h = 0.13;
	};
};

Useful includes

Arma 3 offers a wide range of useful files which can be included to get access to some helpful macros.

Include Code	Description / Content
#include "\a3\3DEN\UI\macros.inc"	Defines for Eden Editor like colors, text sizes custom pixel grid macros.
#include "\a3\3DEN\UI\macroexecs.inc"	Defines for Eden Editor to calculate text sizes etc.
#include "\a3\ui_f\hpp\definedikcodes.inc"	Useful when working with custom shortcuts. Contains defines for key codes.
#include "\a3\ui_f\hpp\definecommoncolors.inc"	Colors used in Arma 3, like background color set by the user.
#include "\a3\ui_f\hpp\definecommongrids.inc"	UI grids such as GUI_GRID and all its variants.
#include "\a3\ui_f\hpp\defineresincl.inc"	IDCs and IDDs of many Arma 3 UIs.

Eventhandlers

To give the dialog its functionality, one will have to use user interface eventhandlers (UIEH). This way you can assign actions to buttons, listboxes, etc.

• User Interface Event Handlers

Scripting

There are several commands to influence your dialog after its initial creation. These command are listed on the following pages:

• GUI Commands
• GUI Functions

Native Arma 3 GUIs

Arma 3 comes with a wide varity of various displays and dialogs. They can be found in:

• configFile usually with names like RscSomeDisplayName or DisplaySomeDisplayName

Additonally, Arma 3 offers some customizeable GUIs which can be accessed by scripts.

• BIS_fnc_3DENShowMessage
• BIS_fnc_guiMessage
• BIS_fnc_GUIhint
• hint, hintSilent, hintC

GUI References

It is sometimes a good idea so see how others created their GUIs. Here is a list of a few resources:

• Terra's Editing Extentions
• A3ExtendedFunctionViewer
• A3UserInputMenus
• A3ColorPicker
• 3den Enhanced
