The plan looks down on the hole: x runs right, z runs down the page, which is the way the tee looks at the cup.

Ground is the floor — its height y and its two tilts sx/sz are what make a ramp. Rails are not drawn: the game fences the edge of the ground for you, and a Gap rectangle is how you ask it not to.

A wall moves three ways: it can slide on a sine, spin about its middle, or swing between two angles and rest at each — a flipper. The plan ghosts where any of them is going, and the checks walk a full cycle of each looking for the phase that shuts the hole.

Machinery is a floor with a motor: a pad can push like a travelator or be sprung like a trampoline, and a hole can carry pipes — drawn here as a ring, a cross and the line between. Pipes are authored in the file; the editor carries, draws and exports them rather than inventing one.

Play mode drags to aim, the slider loads the swing, Space hits it and R puts the ball back on the tee — the real clubs, the real solver.
