gotmachine/PartScaler

PartResizer

This plugin is a continuation of the TweakScale mod for KSP. It is (very) loosly based on the original work from Pelinor, itself a continuation of the work from Goodspeed and Biotronic.

Stuff to do

• Remove the SCALETYPE thing
• Always allow arbitrary scaling (%), stack presets are optional
• Autodetect stack size with some basic attach rules and bounding box heuristics, allow config-defined override
• Allow defining min/max scale on a per-part basis
• Don't use prefab values anymore and persist scaled values instead :
  • In flight, store scaled values
  • In the editor, also store original unscaled values
• Refactor exponent definitions :
  • Separate PART, MODULE, RESOURCE and ATTACHNODE definitions
  • Top level resource blacklist (those resources are never scaled)
  • MODULE definitions can define PART overrides
  • Per definition module blacklist (don't apply the definition if module X is present)
  • Top-level definitions can be overriden by in-module local definitions
  • Those are instantiated as Exponent base class derivatives, which can also implement custom behavior from code
  • Exponents are serialized/persisted on the module to ensure config changes don't break existing vessels/crafts

RESIZER_PART_EXPONENT
{
   massExponent = 2 // dry mass exponent
   costExponent = 2 // base part cost exponent

  // field exponents (compact notation)
  // always applies absolute scaling
  EXPONENTS
  {
    breakingForce = 2
    breakingTorque 2
  }

  // field exponent (detailed notation)
  EXPONENT
  {
    name = buoyancy 
    exponent = 2
    useRelativeScaling = true
  }
}

RESIZER_MODULE_EXPONENT
{
  name = ModuleEngine // module class name
  includeDerivatives = true // are derived classes included
  massExponent = 2 // module mass modifier exponent
  costExponent = 2 // module cost modifier exponent
  
  RESIZER_PART_EXPONENT
  {
      EXPONENTS
      {
        mass = 2
        breakingForce = 2
        breakingTorque 2
      }
  }

  EXPONENTS
  {
    maxThrust = 2.5
  }
}

Things that we might want :

• CrewCapacity scaling
• Prevent downscaling to ridiculous masses

Modding ecosystem review

B9PartSwitch

• Supports scaling out of the box
• The module has a scale field set through the normal module field editing mechanism
• Not sure how a change is detected, B9PS doesn't seem to have an onEditorShipModified callback
• Scaling seems to work right now.
• B9PS can move AttachNodes. Not sure how this will interact.

ConfigurableContainers

• Implements the OnPartScaleChanged callback
• Handle resources on its own

ModularFuelSystem

• Implements the OnPartScaleChanged callback
• Also implements the IRescalable interface

Firespitter

• Seems support is/was on tweakscale side

Other fuel switchers

• SimpleFuelSwitch ?

Mods implementating the IRescalable interface

• OnDemandFuelCells
• InfernalRobotics (the old one, not sure about the new one)
• IFS
• Various stuff in KSPIE
• FAR
