Expansion Xenon Redux UI

Content

Manifest

from Expansion Manager's OXP list from Expansion Manifest
Description Adds backgrounds to all screens, allowing for a narrower screen ratio (eg 4:3). Also includes new title screen music. Also requires the XenonReduxUIResources.oxz. For 16:9 screens, see Xenon UI. 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 Redux 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.XenonReduxUI;
    	if (w) w.$addMissionScreenException("mymissionscreenid");
    
    The OXP is made up of two parts: the main XenonReduxUI.oxz, which holds all the config and code, and the XenonReduxUIResources.oxz, 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.
    
    The images in this OXP are designed screens narrower than 16:10 (eg. 4:3). For a 16:9 and 16:10 screen version, see the XenonUI.oxz.
    
    BGS 1.10 Compatibility
    ======================
    Xenon Redux 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 Reduc UI images. This will be particular apparent on screens like the title page or the load/save page.
    
    If both OXP's (Xenon Redux UI and BGS) are installed in the Addons folder, Xenon Redux UI will normally take priority over BGS.
    
    If both OXP's are installed via the download manager, again, Xenon Redux 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 Redux 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 Redux UI.
    
    To ensure the Xenon Redux 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 Redux 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 Redux 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 Redux 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 Redux UI anytime you like. 
    
    Because of the way the images are created, Xenon Redux UI is still utilising settings in "screenbackgrounds.plist", which may lead to some inconsistencies. For instance, if Xenon Redux UI and BGS 2.0 are installed, when you start Oolite and select the option to open a saved commander, the background will be Xenon Redux UI. Once you have loaded a game, if you then press F2 to load a new game, you will see the BGS background.
