Configuring the core part data

Configuring the core part data in Unity

This part will have to be repeated for each mesh of your mod.

Important
The prefab must be updated after adding a component.
In the Inspector panel: Prefab > Overrides > Apply all.
You also have to re-generate the JSON.

General configuration

1. Add Code Part Data: click on the root object myMod_myPart > “Add Component” > “Code Part Data”.
2. If this option is not available, right-click on the KSP2 package > Reimport.
3. Fill in the form.

Additional configuration

1. Add Module Drag: click on “Add Component” > “Module_Drag”.
2. Depending on what kind of part you are making, you may also want to check one or more of the following pages.
   • Engine configuration (TODO)
   • RCS Port configuration (TODO)
   • Resource Holder configuration (TODO)
   • Decoupler configuration
   • Electric Charge Generator configuration
   • Crewed part configuration (TODO)
   • Command part configuration
   • Reaction Wheel part configuration
   • Antenna part configuration (TODO)
   • Light caster part configuration (TODO)
   • Solar panel part configuration (TODO)
   • Heatshield configuration (TODO)
   • Docking Port configuration
3. Apply Options: select the root part and in the Inspector window near the top on the Prefab line, click the Overrides dropdown and choose “Apply All”. If this option is not available, then you’ve got nothing you need to do here. Move along, move along.
4. Save JSON: at the bottom of the “Core Part Data” panel, click on “Save Part JSON”. Note
5. Generate prefab: move the root object to the Asset folder in the project window. This generates a prefab.

Note: It is important to remember that whenever you make any changes to the prefab or its components, you will need to re-apply the overrides (step 3) and save the updated JSON file (step 4).
