A '''base''' is used in Orbiter to describe a spaceport to be located on a planet, minor planet, or moon by creating a base configuration file, which is used to describe the name, location, and other need information to describe the base.
+
==Creating a landing pad==
  
−
== Base config file ==
+
Orbiter have several .CFG files in the CONFIG directory. Those files describe the properties of objects.
−
The configuration file to describe a base is located in the directory Orbiter\Config\<planet>\Base, for example, when Orbiter launches, it will use Orbiter\Config\Earth\Base\Canaveral.cfg to build the Cape Canaveral spaceport, and will contain certain information to build that base. Information contained in a base configuration file include the name of the base, its location, size, whether the objects described by the file conform to the texture of the planet's surface, any navigation beacons, and a list of objects in the base such as runways, pads, buildings, etc. Orbiter's description for how to build base configuration files is located in Orbiter\docs\OrbiterConfig.pdf.
 
  
−
So let's build a base and see what it looks like as we build it. For this, select a location for the base. For this, I selected a location on the Bonneville Salt Flats figuring it should be pretty flat to build stuff. Looking up the coordinates of the Flat in Wikipedia, sent a ship there and found what looks like water covering much of the area, so I moved the ship a bit until I found dry land that looked reasonably flat for my base.
+
Each planet has a CFG file. For example, for planet Earth there is an Earth.cfg file. In each planet CFG file there is a list of bases, and each base has a CFG file too.
  
−
One way to visually select a location for your base is to launch Orbiter into any scenario. Once launched, unpause if necessary, press {{Key|Ctrl}}{{Key|F1}} which opens the Orbiter: Camera dialog box. In the '''Target''' tab, select the + in front of the '''Sun''', then select '''Earth''' or whichever planet you choose. Then select the '''Ground''' tab. You will now see a distant image of the Earth, use the mouse wheel to zoom in as necessary, and right-click and move the mouse to navigate to a location, zooming in more as necessary.
+
===Finding a location for your base===
  
−
When you find a suitable location and move it to the center of the window, select the '''Current''' button in the '''Ground''' tab, this will update the Position section data. Keep reading here and when you are to type in the longitude and latitude in your base .cfg file, type in or copy and paste the data in that window.
+
The first step to create a base is to find out the coordinates of our base.
  
−
So, let's open Notepad or your favorite text editor. On the first line type in '''BASE-V2.0'''. This identifies the file to Orbiter that it is a base. Save the file in the directory Orbiter\Config\Earth\Base\ with the filename Bonneville.cfg. Now, Orbiter will build the base. All base configuration files must contain that as the first line.
+
Let's open orbiter and load a scenario. Any scenario is good.
  
−
The next line, name the base, in this case '''Name = Bonneville'''. It does not need to be the same name as the filename, for example, in the Canaveral.cfg file, the Name = Cape Canaveral. This way you can use a simple filename for a base with a more complex name.
+
As the mission is loaded, make sure it is not paused. Now press CTRL-F1. Now you see the "orbiter: camera" window.
  
−
The next line contains the location, so type in Location = <longitude> <latitude>, in the case of Bonneville, '''Location = -80.65165 +28.58438'''. The + for positive coordinates is likely not required, but, it may be best to include it to make it less confusing to the reader. This will be the center of the base, and where the yellow square appears when flying nearby the base.
+
There is a " " in the left of the word "Sun" in that window. Click it. Now click on "Earth" (we are going to place a new base on Earth.
  
−
The next line is the size of the base. '''Size = 1000''' for example. This defines the radius of the base in meters. It seems to be arbitrary as there are objects listed in some bases that came with the stock Orbiter 2016 with buildings and other objects that are located inside and outside of this radius.
+
Now push the "apply" button. Use your mouse wheel to zoom in/out. Press right click and move your mouse until the place where you want your base is right in the center of the screen. You may want to zoom in once you have located the location.
  
−
The next line is '''OBJECTSIZE = 100''' which defines the size, in meters, of a typical object on the base. This allows Orbiter to determine the distance that base objects will be rendered on the screen during runtime. Default is 100, objects whose rendered size is less than one pixel will not be rendered until it's visual size exceeds one pixel.
+
Now press the "Ground button" and then the "Current" button. As you see, 3 numbers wil appear in one field in that window. We need to copy and paste the first 2 numbers.
  
−
The next line contains '''MAPOBJECTSTOSPHERE = TRUE''' or '''MAPOBJECTSTOSPHERE = FALSE'''. If this parameter is TRUE, the objects listed for this base will be mapped to the surface of the planet, if it is FALSE, objects will be placed on a flat plane from the elevation of the center of the base.
+
So select the first 2 numbers and copy them to the clipboard. Now we have the latitude and longitude of the base.
  
−
The remainder of the file contains the NAV list, objects such as runways, pads, buildings, etc. and Surface tile list.
+
===Adding a base to the planet===
  
−
So, here, save your file and launch Orbiter with any scenario. In any scenario, Orbiter will read this file along with all the others and build the base in accordance with your information for this base. If you fly nearby, you should see a yellow marker with the name of the base. Each time you edit the file, you need to exit Orbiter back to the launch pad and relaunch the scenario to see any changes. You can exit, make changes saving them, then relaunch. Or you can edit while the scenario is running, save, exit, and re-launch since Orbiter reads the file only during startup.
+
Now close the Orbiter camera window. Now press CTRL-Q to exit Orbiter.
  
−
== Navbeacon ==
+
Open Notepad.
−
Navbeacons are navigation beacons located in various locations about the planet, particularly Earth, which are addressable by your receiver stack, and used by various MFD modes for navigation purposes. VOR transmitters not associated with bases are listed in the planet's config file, e.g. Earth.cfg.
+
Open the Orbiter directory, and then open the Config directory.
 +
Drag the Earth.cfg file to the Notepad window.
  
−
VOR transmitters associated with bases are listed in each base's config file. So, lets add one for Bonneville. In the file Bonneville.cfg, type in the lines '''BEGIN_NAVBEACON''' and '''END_NAVBEACON''' with a space between them. In that space, type in '''VOR KBSF -114.05 4061 112.7 500'''.
+
Scroll down until you find
  
−
Since VOR is the only beacon format used by Orbiter, '''VOR''' must be the first part of the line.
+
; === Surface Bases ===
 +
 +
BEGIN_SURFACE
  
−
The next parameter is the name of the VOR. '''KBSF''' was chosen as a moniker for 'Bonneville Salt Flats' so it is unique, it's not used in Earth.cfg VOR list and not used in any base configuration files.  
+
As you see, there is a list of bases right after that.
 +
Each base has a CFG file.
  
−
The next parameter is the longitude location of the transmitter in decimal degrees, east is positive (+), west is negative (-). KBSF is '''-114.05'''.
+
Let's guess we want to create a base called "Rincon de la Vieja" and let's guess your coordinates are -84.989845  10.739155, and the base properties will be placed in a file called Rincon.cfg.
  
−
Next is the latitude location of the transmitter in decimal degrees, north is positive (+), south is negative (-). KBSF is '''+40.61'''.
+
Between BEGIN_SURFACE and END_SURFACE add a line that reads:
  
−
The next parameter is the frequency of the VOR transmitter in MHz, valid frequencies are 85 to 140 MHz. KBSF is '''112.7'''. It is advisable to check other base config files and the VOR list in the planet's config file to make sure there are not other transmitters using the same frequency that may overlap in any location. The ship's receiver receiving two transmitters' signal at the same time may confuse the receiver and direct you to the incorrect transmitter.
+
Rincon: -84.989845  10.739155
  
−
The last parameter is the distance in kilometers from the transmitter which the ship's receiver can detect a signal, default is 500. KBSF is '''500'''.
+
Notice that instead of those numbers I used, you should paste the numbers that you just had in your clipboard.
  
−
Then the last line should be '''END_NAVBEACON''' which you typed in earlier.
+
Save and exit Notepad.
 +
Now you have added your base to the planet.
  
−
== Object List ==
+
===Creating the landing pad===
−
The next section is the object list which builds objects such as buildings, landing pads, runways, and so forth. So, for the next section type in '''BEGIN_OBJECTLIST''' and '''END_OBJECTLIST''' on two separate lines with a space between. All objects will be entered between these two lines.
 
−
There are separate articles for each of the objects listed below.
 
  
−
Valid objects are:
+
Now open Notepad.
−
*[[Block|BLOCK]] - an object with four sides and a flat roof used for buildings with a flat roof such as offices, stores, etc.
+
Copy the following text and paste in Notepad.
−
*[[HANGAR]] - a building with a barrel-shaped or curved roof and four sides.
 
−
*[[HANGAR2]] - a building with a peaked roof and four sides like a house.
 
−
*[[HANGAR3]] - a building with a barrel-shaped or curved roof reaching to the ground and only two sides at the ends.
 
−
*[[TANK]] - an object that is circular with a flat top, used for, obviously, tanks, and other stuff.
 
−
*[[RUNWAY]] - used for a runway. Obviously a runway can only be used on planets with a substantial atmosphere.
 
−
*[[RUNWAY LIGHTS]] - used to create lights for a runway. includes the PAPI and VASI.
 
−
*[[BEACONARRAY]] - an array of lights in a straight line. Used for night lighting for a taxiway.
 
−
*[[SOLARPLANT]] - a grid of solar panels mounted on the ground. The panels can align themselves with the Sun for best efficiency.
 
−
*[[TRAIN1]] - a train configured as a monorail on a straight track.
 
−
*[[TRAIN2]] - a train configured as a suspension train on a straight track. Note that TRAIN1 and TRAIN2 worked in Orbiter versions up until O2010, but no longer work in O2016.
 
−
*[[LPAD1]] - an octagonal landing pad.
 
−
*[[LPAD2]] - a square landing pad.
 
−
*[[LPAD2a]] - another square landing pad with a different layout for the texture map.
 
−
*[[MESH]] - a generic mesh used for custom objects, must be in Orbiter mesh file formats.
 
  
−
 
+
; === Surface Base ===
−
Each object is defined by several parameters which describes characteristics of that object, including some that have a default value unless you specify values within the object. The object's texture, or what it looks like will be described by one or more lines. For a texture to be used, there must be a file with the extension '''.dds''' in the Orbiter\Textures directory and it must be listed in the file Orbiter\Config\Base.cfg file. Note that if you browse the Textures directory you may find texture files that can be used as object textures but not listed in the Base.cfg file.
+
−
 
+
Name = Rincon de la vieja
−
If you want to see that the texture looks like, you would need a texture viewer. Any textures you would like to use in objects, such as Cape17.dds, just open Base.cfg and type in the filename without the extension into the list in any order and save it.
+
Size = 2000
−
 
+
ObjectSize = 2000
−
To get us started, let's build a landing pad.
+
−
 
+
BEGIN_OBJECTLIST
−
== Landing Pad ==
+
  LPAD2
−
So, in the Bonneville.cfg file, between the BEGIN_OBJECTLIST and END_OBJECTLIST lines type in the following.
+
  POS 0 0
−
 
+
  SCALE 5 0.15 0
−
  LPAD1
+
  TEX Lpad02
−
  POS 0 0 0
+
  NAV 128.05
−
  SCALE 0.75
 
−
ROT 0
 
−
  TEX Lpad01
 
−
  NAV 128.00
 
 
  END
 
  END
−
Save your work, and launch a scenario, any scenario. Orbiter reads the file during launch, but, no time else during the session. So, your updated .cfg file will appear in any scenario if your ship is nearby. Your new landing pad should look like the images on the right:
+
END_OBJECTLIST
  
 +
Now save this as <code>Rincon.cfg</code> in the CONFIG directory, and then exit Notepad.
  
−
[[File:LPad01_Day.png|center|thumb|<center>Landing Pad LPad01 during daytime</center>]] [[File:LPad01_Night.png|center|thumb|<center>Landing Pad LPad01 during nighttime</center>]]
+
Congratulations!! You have created a base with a landing pad.
  
−
== Config file ==
+
===Viewing your base===
−
So, your Bonneville.cfg file should look something like this:
 
  
−
BASE-V2.0
+
You now can open orbiter and load a scenario.
−
Name = Bonneville
+
If you press CTRL-F1 and you click on the " " that is next to "Spaceports".
  
−
Location = -114.05 40.61
+
Scroll down until you find your base.
−
Size = 2000
+
Click on the name of your base and press the "Apply" button.
−
OBJECTSIZE = 100
 
−
MAPOBJECTSTOSPHERE = TRUE
 
−
 
 
−
BEGIN_NAVBEACON
 
−

−
END_NAVBEACON
 
−
 
 
−
BEGIN_OBSERVER
 
−
Bonneville:Bonneville0:-114.05 40.61 25
 
−
END_OBSERVER
 
−
 
 
−

−
END
 
−
END_OBJECTLIST
 
  
−
Save it, launch any scenario and take a look-see. You now have a base with a landing pad. You may need to move a ship to the LPad.
+
Press the "Track" button and then press the "Movable target relative" button.
  
−
See separate articles to build other base objects.
+
You should see your base now.
