Description New background images all standard gui screens, plus new title screen theme music. Needs one of the Xenon UI Resources packs to be installed: Pack A, C, E, G, I, K or M for 16:9 screens, Pack B, D, F, H, J, L or N for 16:10 screens. Choose a pack that matches the font you are using - see resources pack details for information on which font is used. This OXP will override any backgrounds currently applied by other OXP's. This is by design, in order to maintain the illusion of looking at a computer display. If conflicts arise, where important information needs to be given to the player via a background screen, code can be applied to allow exceptions to take place. See the Wiki page for more information.

Xenon UI OXP
By Nick Rogers

About this OXP
==============
This OXP replaces all background UI screens with a new look and feel, based on the assumption that the Oolite UI screens are accessed through some form of computer terminal. 

The method used to add the backgrounds will mean that the background images of most other OXP's, if they set a background, will be overridden with the Xenon UI images. This is by design. 

If an OXP uses background images to convey important information to the player, and the "mission.runScreen" command in the OXP has a "screenID" parameter attached, it is possible to add exceptions to the override by adding the following code to a worldScript:

	var w = worldScripts.XenonUI;
	if (w) w.$addMissionScreenException("mymissionscreenid");

Installation
============
The OXP is made up of two parts: the main XenonUI.oxz, which holds all the config, code and the music file, and the resources pack which holds all the images. This will allow fast updates to the code section, which is small, without having to download the large resources file regularly.

This OXP requires one of the Xenon UI Resource packs to be installed. There are packs for screen ratios of 16:9 or 16:10, and using different fonts for the text. For narrower screens, see the XenonReduxUI.OXZ.

                    Screen Ratio:
                    16:9      16:10
Font:               -------   -------
OCR A Extended      Pack A    Pack B
Xolonium            Pack C    Pack D
Dangerous Square    Pack E    Pack F
Default (Helvetica) Pack G    Pack H
Dosis               Pack I    Pack J
Discognate          Pack K    Pack L
NovaSquare          Pack M    Pack N

F6 Overlay integration
======================
A facility has been provided for other OXP's to supply the overlays on the F6 screen which describe the economy, government, techlevel and sun colors. To use it, add the following code to your startUpComplete world script:

    var xui = worldScripts.XenonUI;
    // "economy":   this defines which section the callback applies to, either economy, government, techlevel or suncolor
    // this.name:   this defines the name of your world script where the function can be found
    // "$returnF6EconomyOverlay":   this defines the name of the function that will be called when the F6 overlay is required.
    xui.$setF6OverlayLookup("economy", this.name, "$returnF6EconomyOverlay");

Then create the function that will be called when the various F6 overlays are requested. 
The parameters "ratio" and "font" will be passed to your function.
"ratio" will be either "16_9" or "16_10", referring to screen ratio of the Xenon UI images currently active.
"font" will be the font name of the font type associated with the Xenon UI resources currently active. Will be either "default", "dangeroussquare", "discognate", "dosis", "novasquare", "ocraextended" or "xolonium".

    this.$returnF6EconomyOverlay = function(ratio, font) {
        return "my_f6-overlay-economy_" + ratio + "_" + font + ".png";
    }

BGS 1.10 Compatibility
======================
Xenon UI is compatible with BGS v1.10, but depending on where each one is installed, one OXP may end up taking priority over the other when backgrounds are selected and displayed. When BGS has priority, its images will be displayed ahead of the Xenon UI images. This will be particular apparent on screens like the title page or the load/save page.

If both OXP's (Xenon UI and BGS) are installed in the Addons folder, Xenon UI will normally take priority over BGS.

If both OXP's are installed via the download manager, again, Xenon UI will normally take priority over BGS.

If BGS is installed via the download manager, and Xenon UI is installed in the AddOns folder, Xenon UI will take priority over BGS.

If Xenon UI is installed via the download manager, and BGS is installed in the AddOns folder, BGS will take priority over Xenon UI.

To ensure the Xenon UI backgrounds appear, the best approach is to make sure they are both installed in the same location.

If you encounter issues where the BGS backgrounds are being displayed rather than the Xenon UI ones, you will need to open the BGS OXP folder, then open the Config folder. Inside Config you will find a 'screenbackgrounds.plist' file. Either remove this or re-name it - perhaps re-name it to 'screenbackgrounds.Xplist' - and the Xenon UI backgrounds will be used without affecting any other aspect of BGS. By re-naming 'screenbackgrounds.plist' rather than removing it you have the option of switching back easily if required.

BGS 2.0 Compatibility
=====================
Xenon UI will hook into Library GUI to register itself as a GUI set. Therefore, you can go to the Library GUI settings and change between BGS 2.0 and Xenon UI anytime you like. 

Because of the way the images are created, Xenon UI is still utilising settings in "screenbackgrounds.plist", which may lead to some inconsistencies. For instance, if Xenon UI and BGS 2.0 are installed, when you start Oolite and select the option to open a saved commander, the background will likely be Xenon UI. Once you have loaded a game where BGS 2.0 is the specified GUI, if you then press F2 to load a new game, you will see the BGS background.

		This OXP replaces all the backgrounds of all UI screens with new versions using a hi-tech-like design theme.
		In most cases any individual backgrounds supplied by individual OXP's on their mission "runScreen" will overridden by these ones (but see below).

		A resource pack is required to complete the system. Depending on the font you are using in Oolite, you may want to use a specific resource pack to match.
		The available packs are:
			Pack name		Font
			--------------- -----------------------------
			Pack A (16:9)	OCR A Extended
			Pack B (16:10)	OCA A Extended
			Pack C (16:9)	Xolonium
			Pack D (16:10)	Xolonium
			Pack E (16:9)	Dangerous Square
			Pack F (16:10)	Dangerous Square
			Pack G (16:9)	Default font (Helvetica Bold)
			Pack H (16:10)	Default font (Helvetica Bold)
			Pack I (16:9)	Dosis font
			Pack J (16:10)	Dosis font
			Pack K (16:9)	Discognate font
			Pack L (16:10)	Discognate font
			Pack M (16:9)	NovaSquare font
			Pack N (16:10)	NovaSquare font
			
		More packs may become available as new fonts are released for Oolite.

		This OXP is designed to be compatible with the BackGroundSet (BGS). However, on some systems some BGS images may still be shown,
		depending on the load order of the OXP's. If this OXP loads after BGS, these images will be used. If BGS loads after this OXP, it's images may be used.

		To disable the BGS images you will need to edit BGS, and rename the "screenbackgrounds.plist" file in the "Config" folder to something like "xcreenbackgrounds.plist".

		If your OXP has backgrounds you want to keep, and you want to still use this OXP, use the "$addMissionScreenException" to your startUpComplete script:
		Example:
			var w = worldScripts.XenonUI;
			if (w) w.$addMissionScreenException("mymissionscreenid");

		Note: When mission screens exit to the short or long range charts, the backgrounds are not being set. So a timer is in place to force the background on.
