Bananabench Async

Script defined in lua/console/bananabench-async.lua. Async/coroutine-based variant of the bananabench physics benchmark. Uses coroutine.yield() during physics steps to allow frame-by-frame execution.

Functions/Exports

benchPhysics(vehicles, vehicleMin, vehicleMax) (global)

Coroutine-compatible benchmark function. Same structure as the core bananabench but uses coroutine.yield() in the update loop instead of direct BeamEngine.update calls. Tests with both dynamic collision ON and OFF.

• vehicles - vehicle names (default: {'pickup'})
• vehicleMin - min count (default: 1), vehicleMax - max count (default: 12)
• Outputs table with dynamic collision vs no-collision comparison

myBenchStep(testVehicle, n) (global)

Spawns n vehicles, yields for gfxSteps frames, measures total time.

benchLog(level, origin, msg, newline) (global)

Log caching function (same as core bananabench).

benchmark_start() (global)

Creates a coroutine wrapping benchPhysics. Call once to initialize.

benchmark_update() (global)

Resumes the benchmark coroutine. Call each frame.

getAllVehicles() (local, unused)

Scans /vehicles directory and returns list of all vehicle names. Defined but not called in this script.

formatRes(res) (local, nested inside benchPhysics)

Formats a single result entry (MBeams/s and % realtime) for table output. Nested helper within the print loop.

Configuration

• physicsFPS = 2000, physicsSteps = 100, gfxSteps = 20
• version = '0.4'

Usage

benchmark_start()  -- initialize coroutine
-- then call benchmark_update() each frame

Internal Notes

• Requires lua/console/test at startup
• Unlike core bananabench, uses BeamEngine:spawnObject (not spawnObject2) and vec3 (not Vector3)
• Compares dynamic collision on vs off in a 2-column output
• Uses M = {} as global (not local), no module return - standalone script pattern
• Older version (0.4) compared to core bananabench (0.5)
