Adjustable Tech Car Tuner

Live editor app for tuning the adjustable tech car's dimensional variables (wheelbase, track width, overhang, body width, weight, CoG, yaw inertia) with a visual measurement overlay.

Tunable Variables

VariableFormatDescription
$wheelbase%.2f mDistance between front and rear axles
$overhang_F%.2f mFront overhang distance
$overhang_R%.2f mRear overhang distance
$trackwidth_F%.2f mFront track width
$trackwidth_R%.2f mRear track width
$bodyWidth%.2f mBody width
$weightscale%.2f xWeight multiplier
$cogOffsetY%.2f xCentre of gravity Y offset

$yawInertia%.2f xYaw inertia multiplier

Usage Example

-- Only works with the "adjustable_tech_car" JBeam vehicle

-- Open via Vehicle Editor > Live Editor > Adjustable Tech Car Tuner
-- Or programmatically:
extensions.editor_vehicleEditor_liveEditor_veAdjustableTechCarTuner.open()

-- The tuner displays:
-- * Side-view car image with measurement lines for:
--   - Front overhang, wheelbase, rear overhang
-- * Bottom-view car image with measurement lines for:
--   - Front track width, rear track width, body width
-- * Float sliders for weight, CoG offsets, yaw inertia

-- Each slider maps to a JBeam variable ($wheelbase, $trackwidth_F, etc.)
-- Variables are bounded by their min/max defined in vdata.variables

-- Click "Apply" to push all tuning changes to the vehicle:
-- This calls core_vehicle_partmgmt.setConfigVars() which
-- triggers a vehicle reset with the new variable values

-- Measurement lines are drawn using ImGui draw list with:
-- * Connecting lines from image reference points to measurement area
-- * Arrow endpoints on horizontal/vertical measurement lines
-- * Inline float sliders at the midpoint of each measurement
