MFD (Multi-Function Display) is implementation of HUD (Head-Up Displays) in Arma 3. Display can be fixed on helmet (move with player head) or cockpit (static position). THIS PAGE IS WORK-IN-PROGRESS, USE AT YOUR OWN RISK.


Technical Basics

HUDs are defined in the MFD class of the source vehicle. The properties of each HUD are separated by a root class (conventionnally named AirplaneHUD in base content), although each new instance will render a new HUD and overlap with the previous. This makes it easier to configure HUDs by modular config (for example, navigation, targeting, etc...). All HUDs are defined through 3 base elements :

  • Bones : invisible elements used to transform/rotate other, similar to anchors/origins. Defined in the Bones class of any HUD.
  • Drawn elements : used to draw graphic elements. Defined in the Draw class of any HUD.
  • Sources : if an element displays complex variables or any bone needs to be in specific positions, it uses a source data. Defined in each instance of bone and draw classes when needed.

Example : 

class MFD {
	class AirplaneHUD {
		globalProperty = ...; // global HUD properties
		// bones definitions
		class Bones {
			class BoneInstance {
				type = ...; // type of bone
				source = ...; // source for bone transformation
				properties = ...; // other bone properties
			};
		};
		// HUD-Elements definitions
		class Draw {
			class HUDElemetInstance {
				type = ...; // type of HUD-Element
				source = ...; // source for display value
				properties = ...; // other HUD-Elements properties
			};
		};
	};
};

Since A3 1.69 version it's also possible to define MFD class in cfgMagazines. Such move allows creating dynamic MFD screens with info on the screen corresponding to current loadout applied through dynamic loadout system.

Example : 

class CfgMagazines
{
    //... some config ...//
 
    // magazines definition
    class magazine_Missile_AGM_KH25_x1 : VehicleMagazine
    {
        //... some config ...//
 
        // mfdElements - class where
        class mfdElements
        {        
            class Plane_Fighter_02 // unique name that you can later reference in plane MFD
            {
                class Bones {};    // bones are supported
                class Draw
                {

                        // black background
                        class Background

Global HUD Properties

These are defined in each AirplaneHUD instance and affect every sub-sequent element. Some properties can be overwritten in each child element if needed (e.g color) :

  • color : [r,g,b,a] - color of all elements.
  • topLeft : "string" - memory point defining the top left position of the HUD and uses it as the absolute origin (0,0,0). Not used if helmetMountedDisplay = true.
  • topRight : "string" - memory point defining the top right position of the HUD and uses it as the far right limit (1,0,0). Not used if helmetMountedDisplay = true.
  • bottomLeft : "string" - memory point defining the bottom left position of the HUD and uses it as the bottom limit (0,1,0). Not used if helmetMountedDisplay = true.
  • borderLeft : float - adjust position inside of memory points LOD. Not used if helmetMountedDisplay = true.
  • borderRight : float - adjust position inside of memory points LOD. Not used if helmetMountedDisplay = true.

Bones

Bone defines position of graphic element. Final position can be modified by sources in each frame. Bones have no hierarchy, hierarchical geometry is available by chain of bones in HUD-element draw.

Scene To HUD Transformation

Transformation of 3D vector from scene to 2D vector on HUD plane is implemented by two 2D vectors:

  • pos0: 2D position on HUD plane of ray defined by source (center)
  • pos10: 2D position on HUD plane of ray, which have angle to previous ray 10 degrees in axes X and Y
  • pos3: the same as pos10, but angle is 3 degrees only. It is used in ILS.

Example : 

class Velocity {
	type = vector;
	source = velocity;
	pos0[] = {0.5, 0.5}; // center of HUD for source vector
	pos10[] = {0.2, 0.2}; // 20% offset for 10 degrees vector
};

Points Definition

Lines (or multi-lines - line with more segments) are defined by array of points. In one points array can be defined more lines. Lines must be splitted by separator. Each point can be transformed by more bones (bones chain).

  • Point: defines one point of line. Point is define as chain of triplets (see next bullet: Bones chain). Triplet defines one transformation step of point:
    • bone name (string): name of bone for point transformation. Bone name is optional, but one of bone name or offset must be defined.
    • offset ([x, y]): offset applied to transformation. Offset is optional, but one of bone name or offset must be defined.
    • weight (float): weight to multiply transformation, must be defined.
points[] = {
	{boneName, {offsetX, offsetY}, weight}, // full definition
	{{offsetX, offsetY}, weight}, // without bone
	{boneName, weight}, // without offset
	{boneName, {[boneName transform only coordinates in this group],0, 0}, weight}, // the same as previous one
	{1} // ERROR: weight only
};
  • Bones chain: each point can be transformed by more bones. Transformation chain is defined as array of triplets. Transformation order is from left to right. Example (without offsets to simplify):
points[] = {
	{bone, 1}, // 1 transformation
	{bone1, 1, bone2, 1}, // 2 transformations
	{bone1, 1, bone2, 1, bone3, 1} // 3 transformations
	// etc...
};
  • Line: points array with more than 1 point defines line (or multi-line with more than 2 points). See example below.
  • Separator: in one points array can be defined more lines. Lines must be splitted by separator. Separator is empty array {}.

example: 

points[] = {
	// one-segment line
	{bone, {0, 0}, 1},
	{bone, {1, 1}, 1},
	{}, // lines separator
	// rectangle: 4-segments multi-line
	{bone, {0, 0}, 1},
	{bone, {1, 0}, 1},
	{bone, {1, 1}, 1},
	{bone, {0, 1}, 1},
	{bone, {0, 0}, 1}
};
