CombatMFD

From Elite Wiki
The Combat MFD is the top left. The top 4 lines are your status, the next 5 lines are the targets, the 10th line a second target. The top right MFD is from Telescope, showing the closest targets - the bracketed one is the current target

Overview

The Combat MFD (Multi-Function Display) displays information about your ship and your enemies.

Information about your ship

Information about your target

  • name,
  • distance, mass and speed,
  • shield radius, then Front/Aft orientation display and Damaged!/Weak!/Derelict flag,
  • laser weapon type and range (after a shot),
  • status: Clean/Offender/Fugitive, if derelict then Trap or Treasure/Empty/Mined/Usable (see Towbar OXP).
  • fired missiles counter with "Hard" flag.

More information

Telescope can display the most recently detected target in the last line.

Usage & Purchase

Use the ";" and ":" keys to select an MFD and enjoy the view. ;)

  • Costs 1,000₢ and is available from TL5 and higher.
  • See MFD for more detail on managing MFDs & Priming Equipment for more details on priming oxp's such as CombatMFD.

Detail

Compatible with Telescope OXP (if locking distant targets) and ShieldEqualizer+Capacitors OXP: if shields are over 100% then either Shield Boosters are installed or Shield Capacitors are also filled.

The "Damaged!" flag is shown when the target's exhaust plumes are blinking (below 40% energy) and "Weak!" is shown when blinking strongly and sparking too with CustomShields OXP (below 20%).

If your HUD has support for this (like NumericHUDv3.25) then you will see these words near your crosshairs too. Such support means the following lines will appear in the legends section of your hud.plist: 

{ equipment_required="EQ_DTADAM"; x=30; y=40; y_origin=0; height=20; width=16; text="Damaged"; alpha=0.5; },
{ equipment_required="EQ_DTAWEA"; x=30; y=40; y_origin=0; height=20; width=16; text="Weak"; alpha=0.5; },
{ equipment_required="EQ_DTADER"; x=30; y=40; y_origin=0; height=20; width=16; text="Derelict"; },

SEE indicator

The top right corner shows letters indicating how many shields, and how much armour and energy are remaining. Each letter represents 2 energy banks in strength and is ordered from the outside to the inside. Small letters indicate that only one side is up.


"SEE" indicates that you have basic Shields (2 banks=128 points) and 2*2 Energy banks filled (4 banks=256 points): as a starting Cobra Mark III at Lave.

The total length is relative to your ship's defensive strength. The strongest Andromeda has CCCCCCCCMBSAAAAAAAAHHHEEEEEEEE. :)

A letter will be changed to "-" on dropping below the half of the banks represented by this letter. "-E" indicates that less than three and more than one bank is filled.

Underscore "_" indicates equipment damage preventing regeneration: you should fix it when docked. Checked damages:


The number in the corner show the total value in your energy banks (64 points).

If you see "LAST BANK!" here instead of letters then ... well, ... you know! (Flee! ;))

Equipment indicator

Next to the shield values there are letters which show if the following equipment is installed and primed:

One-shot indicator

The space to the right from your shield percentages shows letters to indicate one-shot equipment. In order:

Custom HUD dials

  • For a more comprehensible introduction to this, see Phkb's post here.
  • The only HUD which currently (July 2023) uses these custom dials is the Vimana HUD

Oolite v1.81 provides drawCustomText: a HUD dial displaying information without an MFD.

You still must buy the CombatMFD equipment for the following but you need not display the MFD if your HUD has support for these (such as the Large and Small HUDs which come with HUDSelector).

CombatMFD fills up the following dials with values, so HUD designers can use these: 

Alphabetic order                                                                    Thematic order	(target information, then player ship)

The current target is that which has been targeted on the View Screen (visible if STE is installed), the space compass target is that of the Compass (or the ASC), the Telescope "targets" are those listed on the Telescope MFD

Numeric values are centered in a 28 character wide field by default, texts are left aligned (you can align to right in a hud plist with align=1).

The default width of centered fields is adjustable in the worldScripts.combat_MFD.$DW variable.

If $DW is 0, then all fields will be left aligned.

If $DW is negative, then right aligned in the given width.


Using the drawCustomBar: selector HUDs can give graphical feedback about the following values: 

data_source   	description
combatAftShBar	aft shield bar including capacitors
combatCargoBar	how filled the cargo bay of player ship
combatFwShBar	forward shield bar including capacitors
combatSEEBar	total durability bar of player ship based on the SEE indicator
combatSLBar	service level bar of player ship

See this example to add a service level bar to your HUD (the yellow "hull" bar below in the left middle of the HUD) - see Maintenance.


Original and Large HUDs use many custom dials (available in HUDSelector): CombatMFD1.9.png


For example the speed value needs the following code in the dials section in the plist of your HUD: 

{
	data_source = "combatSpeed";
	selector = "drawCustomText:";
//	alert_conditions = 2; //uncomment if you want to see in green alert only
	alpha = 1.0;
	height = 13;
	width = 15;
	x = 151;
	y = 87;
	y_origin = -1;
},


OXP developers can reach all data in worldScripts.combat_MFD.$Data object using the same data_source key names, so for speed use $Data.combatSpeed .

The access of worldScript name is slow, so you should get a pointer once in startUp: 

this.startUp = function() {
	this.$combatWS = worldScripts.combat_MFD; //slow access for the pointer, one time only
}
this.$displaySpeed = function() {
	if( this.$combatWS ) //must check CombatMFD existence to prevent an error
		player.consoleMessage( this.$combatWS.$Data.combatSpeed ); //fast access
	else log(this.name, "Can not display speed value, CombatMFD OXP is missing");
}


The $DataArray contain all available data_source keys. 

this.$combatKeyIsExists = function( key ) {
	if( this.$combatWS && this.$combatWS.$DataArray.indexOf( key ) > -1 )
		return true;
	else return false;
}


The $DataShow can disable the display of any data in the HUD: 

this.$disableKey = function(combatKey) {
	if( this.$combatWS ) this.$combatWS.$DataShow[combatKey] = false;
}

Dependencies

Oolite 1.79 or later.
