Precompile Vehicles

Dependencies

M.dependencies = {'freeroam_freeroam', 'core_vehicles'}

Iterates through a predefined list of vehicles, spawning each on smallgrid with synchronous shader compilation to warm caches.

Overview

util_precompileVehicles is a build-time utility that spawns every vehicle in a hardcoded list (100+ models) one at a time on the smallgrid level, waits 200 frames for shaders to compile, then moves to the next. Quits when done.

Internals

Vehicle List

A hardcoded table vehiclesToLoad maps ~110 model names (e.g. pickup, etk800, vivace, us_semi) to true. Only models also present in core_vehicles.getModelList() are processed.

Flow

1. onInit - disables async shaders, builds filtered vehicle list, starts smallgrid via freeroam.
2. onClientStartMission - triggers the first loadNextVehicle() call.
3. loadNextVehicle - calls core_vehicles.replaceVehicle(model, {}).
4. onVehicleSpawned - sets loaded = true, frames = 200.
5. onPreRender - decrements frames; when 0, advances to the next vehicle or calls quit().

State Variables

• vehicles - filtered array of vehicle model names
• vehicleToLoad - current 1-based index
• loaded / frames - control the per-vehicle wait
• finished - stops onPreRender processing

How It Works

1. Extension loads, starts smallgrid freeroam.
2. For each vehicle: spawn → wait 200 frames → next.
3. After all vehicles, logs completion and exits.

Lua Examples

-- Typically invoked via CLI, not at runtime:
-- beamng.exe -onLevelLoad_ext "util/precompileVehicles"

extensions.load("util/precompileVehicles")
