Adds buildable shuttle docks with reinforced, retractable roofs.
Allows shuttles to land safely inside enclosed or surface bases while maintaining overhead protection when not in use.
The dock comes in 4 sizes: 5x5, 7x7, 9x9, 11x11.
When built, just like mining rocks permanently changes the terrain, the dock will permanently remove any overhead mountain and replace it with a reinforced roof. If for some reason you need to restore the overhead mountain, you should be able to use dev mode.
The dock can be opened and closed.
While closed, the roof is as strong as overhead mountain so it protects from sieges and drop raids.
When opened, the roof is temporarily removed and ships are free to come and go. This does also means drop raids can pod in.
Whether closed or opened, the dock reduces infestation chances to near zero.
Rimworld's built in wall lamp can be connected to the dock to indicate if the dock is opened or closed. The default colors are green and red but can be configured to whatever colors once its connected. The dock can support multiple wall lamps. If a wall lamp is disconnected or the dock is destroyed, the wall lamps will revert to their default colors.
The dock supports other buildings on top. The only buildings that can't be on top are other "floor" buildings which sit on the same layer.
Rimworld doesn't natively support shuttles on landing buildings like the dock so some code needed to be added via Harmoy. This may or may not cause some sort of mod conflict if another mod had to do the same so it may not be compatible with all mods.
For gravships, you can build the dock in a gravship and fly around with it but you can't really put a gravship in the dock. The dock works by removing the roof when it opens up so it would remove the roof of a gravship.
⚠ Safe to add mid-save
⚠ Can be removed mid-game after deconstructing the dock and any attached wall lamp
I am not an artist, you are free to create your own textures.

Modders:
You can easily create your own docks. The dock system is flexible and the sizes are not hardcoded. The dock uses the <size> tag. Set your building's size tag to whatever sizes you want.
For example a building with
<size>(21, 21)</size>
Will produce a dock of that size.
The current texture is made for square buildings, so if your dock is a rectangle, you will probably need to add your own texture.
You can look at the 5x5, 7x7, and 9x9 defs as examples.
You can also attach your own lights if the light supports Rimworld's color change component: CompGlower.
You can look at how I add Rimworld's wall lamp in the patches folder.
Mod compatibility:
SOS2: If SOS2 is active, a new toggle will appear to use the mods roof instead. You need to manually toggle this ON in the dock.
