[1.2] VOID 1.1.0-beta - Vessel Orbital Informational Display


Recommended Posts



If you love at-a-glance information on your flight conditions, detailed information about your orbital dynamics or upcoming transfer maneuver, then VOID is a solution for you! Is it the solution for you? Give it a try and find out!

I've long used VOID to fill the void (doh!) for detailed orbital, surface, and vessel information without adding any new functionality that other mods may focus on. As I find new data that I "need" for my missions, I've been slowly adding information to my own VOID displays and am honored to continue development following Iannic-ann-od's stellar release series. Many thanks Iannic-ann-od!

* VOID_VesselInfo: Resource mass no longer a combo line.
* VOID_HUD/AdvancedHUD: Fixed an issue where certain changes in the game and other mods would cause the HUD skin to change.

* License changed to modified BSD.

v.0.9.17 [2013-12-14]
* BUGFIX: Corrected the visibility of the Toolbar buttons when using Blizzy's Toolbar.

v.0.9.16 [2013-12-14]

* TWEAK: Values with configurable precision will now manipulate the unit prefix (e.g. Mm vs. km vs. m) instead of just adding a bunch of digits after the decimal.
* TWEAK: Precision cycling is now toggled by clicking anywhere on the label or value of configurable values.  Configurable values are now denoted by an "â±".
* TWEAK: Precision cycling now limits itself within reasonable bounds.  Right-clicking now cycles through precision values in reverse.
* BUGFIX: Will no longer sometimes cause exceptions before the scene is fully loaded.
* BUGFIX: Improved failsafes around VesselSimulator calls.

v.0.9.13 [2013-11-20]
* BUGFIX: Re-added "Primary" indication to the left-side HUD, because I suck at merging git branches or something.

v.0.9.12 [2013-11-17]
* FEATURE: Added a configurable precision for some values in the Orbital pane as a trial run.
* FEATURE: Added support for real-time rate limiting to keep overhead down (see "Update Rate" in config).  Currently only supported by Orbital.

v.0.9.11 [2013-11-12]
* Moved the editor HUD to the top left corner to avoid conflicts with the staging selector.  It should move with the parts list, as relevant, as well.

v.0.9.10 [2013-11-12]
* FEATURE: The VOID framework now supports Editor modules!  A very rudimentary HUD has been added to the editor by default.  Please recommend additional information and features to include!
* BUGFIX: The VOID icon can be relocated again.  Uncheck "Lock VOID Icon" in the Configuration menu and drag it where you want it.  Note: in the editor, the button-dragging doesn't work, so the icon is docked to the main VOID window.
* BUGFIX: Changes to the skin are now correctly saved and reloaded.
* VOID windows now "clamp" to the edge of the screen so they cannot inadvertently be lost.

v.0.9.9 [2013-11-10]

* BUGFIX: The activity label on the csv logging window now appears correctly.

v.0.9.1 [2013-11-02]
* BUGFIX: Surface longitude and latitude now display in a more traditional 180°W-180°E format.
* FEATURE: The current primary body is now shown in the HUD.
* NOTICE: SpacePort is calling the download -0-9-15 for some reason; this is a mislabeling on their part; there is no version 0.9.15.

v.0.9.0 [2013-10-23]
* FEATURE: Added delta-V calculations via VesselSimulator, courtesy cybutek.  Now visible for the current stage and the whole vessel in the "Vessel" information pane.
* BUGFIX: Local sidereal longitude should no long occasionally fall outside the [0..360] degree range.
* BUGFIX: Sub-zero elevations should now work correctly on bodies without oceans.

* Improved the Rendezvous Information window which is also now accessible from the main menu
* Can now set in-game targets and show rendezvous info according to selected in-game target
* Fixed small a bug or two and cleaned out a lot of un-needed GUILayout lines

Can anyone send me a link to the a 0.21 compatible version of VOID please? Looks awesome and I really need some of the info for a project but I'm working at sea and the internet here just isn't up to downloading 0.22.

Did try the 0.22 version but it breaks the game.

@toadicus: Thanks! Been having a lot of issues getting Engineer to work on Linux, and so far VOID works so extremely well that I'd rather have it be a one-stop shop. If you can get dV to calculate, it'd be awesome if it could display it in the VAB as well.

0.9 looks good! Thanks again for stepping up and taking charge of the VOID. Don't be afraid to message me if you have questions about any of my janky code. It was an absolute beginner crash-course learning project from Day 1 and the code reflects that in many places!

Just for fun, the evolution of VOID from KSP 0.16 to 0.21.

Is there any documentation, either with the mod or on the web somewhere, itemizing all that this mod does? I don't use mechjeb for autopilot much, but I do use it for Smart ASS and the data screens. What I most use it for is landing predictions and the connected aerobrake predictions. I rarely use the landing autopilot, but the prediction system built into it is very useful. Is anything similar to that included in VOID?

Right now in my challenge save (and AAR save) I'm pretty much all set up, but maybe I'll check void out for my next setup. Thanks for answering my question Toadicus. This looks very well done and has lots of information on hand.

Thank you toadicus for your work.

Something I had noticed in the previous version, it still gives Moho a 14km high atmosphere. Just a detail.

This isn't VOID, that's KSP. All the CelestialBody viewer does is pull the list of bodies from FlightGlobals.Bodies and spit out the information available through the API. VOID reports a 14 km atmosphere altitude because that's what Moho says it has.

This is an incredible mod, especially the HUD which makes navigation practical.

I have a suggestion for the next version. Typically longitude is displayed in the range of -180 to +180 degrees, with the negative values being considered West and the positive values considered East. For example the Wiki has KSP on the equator at about 75 W.


Currently, VOID is displaying that as 285 E, which would be an untypical way to reference longitude. The code in the green box would always keep the API's longitude in the correct range and allow the HUD to display it properly. Also, since the HUD is now 5 lines on the right side, perhaps the primary body could be added to the left side. This would seem to balance the Biome information on the right as well.

I was able to get this to work with the following changes. Up to you of course, just wanted to see if I could do it. Thanks for the excellent mod.


Can anyone see the picture...for some reason I can't get it to work.
