cargo run --release -p openmx -- --track free06        # straight onto a track, no menu
cargo run --release -p openmx -- --players 2 --split v # two players, side by side
cargo run --release -p openmx -- --vehicle biplane     # start in the track's biplane

What is in it

The ride. The bike’s ground step — suspension, tires, the rigid body, engine torque, slip, the air state and the collision sweep — on the parameters each bike’s own .phy carries. The rider on top of it: the trick machine and its 24 stunts from the disc’s stunts.ini, landings judged against the .phy’s limits, wrecks, the ragdoll and the put-back. The track’s biplane,…
