ChainShape:getPreviousVertex

Available since LÖVE 0.10.2
This function is not supported in earlier versions.

Gets the vertex that establishes a connection to the previous shape.

Setting next and previous ChainShape vertices can help prevent unwanted collisions when a flat shape slides along the edge and moves over to the new shape.
