Shapes are solid 2d geometrical objects used in love.physics.

Shapes are attached to a Body via a Fixture. The Shape object is copied when this happens. Shape position is relative to Body position.

Constructors

love.physics.newChainShape Creates a new ChainShape. Added since 0.8.0
love.physics.newCircleShape Creates a new CircleShape.
love.physics.newEdgeShape Creates a new EdgeShape. Added since 0.8.0
love.physics.newPolygonShape Creates a new PolygonShape.
love.physics.newRectangleShape Shorthand for creating rectangular PolygonShapes.

Functions

Object:release Immediately destroys the object's Lua reference. Added since 11.0
Object:type Gets the type of the object as a string.
Object:typeOf Checks whether an object is of a certain type.
Shape:computeAABB Returns the points of the bounding box for the transformed shape. Added since 0.8.0
