Custom Parts Config Provider

Overview

• Node Name: Custom Parts Config Provider
• Category: provider
• File: extensions/flowgraph/nodes/vehicle/customPartsConfigProvider.lua

Provides an interactive editor for building a custom vehicle parts configuration. Allows loading configs from files, copying from the current vehicle, and manually editing part slots and tuning variables. Outputs a model name and config table usable by vehicle spawn nodes.

Key Methods

Editor Sections

1. Load from File - Uses the vehicle selector UI to pick a model/config .pc file, then loads it with jsonReadFile.
2. Current Vehicle - Reads config from the player vehicle. Supports reading from .pc files or deserializing inline configs. Offers "Copy from Vehicle", "Copy only Parts", and "Copy only Vars" buttons.
3. Parts Editor - Editable key-value pairs (string keys → string values) for JBeam slot assignments.
4. Vars Editor - Editable key-value pairs (string keys → float values) for tuning variables.

How It Works

1. The node stores a partConfig = {parts = {}, vars = {}} table internally.
2. The custom properties panel lets the user populate this config from files or the current vehicle.
3. Parts and vars can be manually added, edited, or removed through the ImGui interface.
4. On each frame, work() outputs the config table and model string for downstream nodes (e.g., spawn vehicle).

Usage Example

-- In a flowgraph:
-- [Custom Parts Config Provider] → model → [Spawn Vehicle]
--                                → config → [Spawn Vehicle]

-- The partConfig structure:
local partConfig = {
  parts = {
    ["slot_engine"] = "engine_v8",
    ["slot_transmission"] = "transmission_6speed",
  },
  vars = {
    ["$spring_F"] = 45000,
    ["$damp_F"] = 2500,
  },
  partConfigFilename = "/vehicles/etk800/sport.pc"  -- optional
}

Key Dependencies

• jsonReadFile() - loads .pc config files
• core_vehicles.getModel() - retrieves available configs for a model
• ui_flowgraph_editor.vehicleSelector() - shared vehicle/config picker widget
• ffi - for ImGui text input buffer handling
