PolskiDesign Roller Coaster Tracks (2D)
2D roller-coaster track designer: shape the first hill, the loop radius and the track friction with real energy-conservation physics — a chain lift, gravity, friction and a live G-force readout decide whether your loop is survivable.
This 2D companion turns the 3D ride-along coaster into a track-design lab: instead of only watching a fixed spline from an orbiting camera, you shape the first hill's height, the loop radius and the track's friction yourself, and a real physics engine — a chain lift, gravity, friction and a live G-force readout — decides whether the cart clears the loop or stalls partway up and rolls back down, exactly as a real coaster would.
Energy-conservation track designer: the cart's speed is integrated frame by frame from gravity resolved along the local track slope minus a simplified friction loss, with an exact vertical-circular-motion check (v ≥ √(gR)) deciding whether the loop is survivable at the chosen hill height and radius.
