# wheel-invalid

> Talos 0.7 · Since 0.6

A `wheel` that cannot work: no dynamic rigidbody above it; a number non-finite, non-positive where it must be positive, or a fraction outside 0..1; no radius on a wheel no vehicle composes; a second `wheel` component on one entity; or an entity in its `visuals` that cannot turn with it (missing, the wheel or above it, below it, with a rigidbody, on another body, or drawn by another wheel).
