First, you're going to need an idea for a ship, and some artwork to represent it. You can use one single image, or you can include north, east, and south versions like I have.

Honestly you only need to have one graphic image because of the fact that the ships always point north when they land, regardless of position.


Find this mod's folder, typically located under steam/steamapps/workshop/content/294100/1845423808

There are three locations you need to know about (all within the Defs folder):
- ThingDefs_Buildings contains 1 def per ship
- ThingDefs_Misc contains 3 defs per ship




All of the magic is in the first def. The three remaining defs are just graphics placeholder for the code to lift off and land the shuttles.

The only thing you should change in ALL of the defs is in this area:

texPath: the graphic filename of the ship, located in the Textures folder. If you are using a Graphic_Multi (more on that below) make sure you don't include the _east, _north, etc. Just the base name of the graphic file.
graphicClass: This wants to know if you are using one graphic to represent your ship, or if you have an east, south, and north variant. If you want one single graphic use Graphic_Single. If you want to use directional graphics, use Graphic_Multi.
drawSize: This is how big the graphic should be drawn, and is independent from the actual size of the clickable building. All of my ships extend off the edge a little bit to make it look bigger.

For the three placeholder defs with _Active, _Leaving, and _Incoming, it's important they share the same exact name as the ship def, but with the extras added afterwards.

For example, if you name a ship Orca, the other defs MUST be named Orca_Active, Orca_Incoming, and Orca_Leaving.

====================================


Now that you know where and why, let me show you how.


Find the folder steam/steamapps/workshop/content/294100/1845423808 and right click 1845423808 and copy it into your clipboard. This will grab everything from SRTS Expanded.

Now, find your actual Rimworld mods folder: steam/steamapps/common/RimWorld/Mods

...and PASTE the folder you copied into the mods folder. Rename it whatever you want.

Open the folder. Delete all of the following from the new folder: .git, .gitattributes, Source, Assemblies, Languages, and Patches. Additionally, delete all of the artwork inside Textures, but leave the folder because you will need to put your own artwork in there.

Inside Defs, delete DesignationCategories, WorldObjectDefs, and ResearchProjectDefs. We don't need them.

Open Buildings_SRTSExpanded.xml and Things_SRTSExpanded.xml in your favorite text editor. I suggest Notepad++ or Sublime Text.

Inside you will find 4 sets of ships, all represented with 4 sets of defs each, as described before. Use these to reference and build a ship to your liking. All of the properties are pretty self explanatory, but as always I am happy to help and answer questions here.

You don't need a research project to unlock your ship, but you are more than welcome to. Just copy how I did my research projects, and make sure to set the <prerequisites> to point to the previous research that is needed to unlock this one.

Using CP's Helicopters mod?: I highly suggest you change your <designationCategory> to Misc, otherwise you will need to edit the file under Patches folder to include your ship. This is important.

The <Mass> of a ship should be 2-3 times the combination between the ship's carry capacity and it's fuel reserve tank. If a ship has 1,000 kg carry and 1,000 L of fuel, it should theoretically have a mass between 4,000 kg and 6,000 kg. This only matters for immersion, not function.

Your ships MUST have the following code, but you are free to adjust the numbers as you see fit:

ComProperties_Transporter indicates how much of anything you can carry. Don't change restEffectiveness.

SRTS.CompProperties_LaunchableSRTS is REQUIRED BY ALL SHIPS.

CompProperties_Refuelable controls how much fuel you can carry and how efficient the ship is at flying.


Lastly, you will need to edit your About.xml and Preview.png files in the About folder. These are very easy to understand, and I'm happy to explain to anyone.

AS ALWAYS: Make sure your load your brand new mod AFTER SRTS Expanded.
