Rectangle

Returns this polygon's axis aligned bounding box.

Moment of inertia for a rotation about this shape's COM.

Creates a new body made out of tis shape.

Returns this shape's containing body.

Flag determining this shapes ability to collide with other shapes.

Checks if the point point is contained in this polygon.

A ray is created, originating from the point and following an arbitrary direction (X-Axis was chosen). The number of intersections between the ray and this polygon's sides (including vertices) is counted. The amount of intersections with vertices is substracted form the previuos number. If the latter number is odd, the point is contained in the polygon.

Density. (Mass per area)

This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

The default implementations of this method is an equivalence relation:

• It is reflexive: for any instance x of type Any, x.equals(x) should return true.
• It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).

Part of the coefficient of friction for a collision between this shape and another. The coefficient of friction is calculated out of the product of this part and the other shape's part.

Returns the vectors from the center to the vertices of this rectangle. The first vertex is the upper-right vertex at a rotation of 0. Vertices are ordered counter-clockwise.

Returns a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Returns the mass of this shape. The mass is given by volume times density.

Position of this shape's COM (in world coordinates).

Returns the projection of this polygon onto the line given by the directional vector axis.

Local position of this shape's body COM to its COM at a body rotation of zero.

Part of the coefficient of restitution for a collision between this shape and another. The coefficient of restitution is calculated out of the product of this part and the other shape's part.

Rotation of this shape about its COM.

Initial rotation. Rotation of this shape before it was added to a body.

Returns all sides of this polygon. The sides are ordered counter-clockwise, the first vertex of the side giving the side index.

Returns a string representation of the object.

The default representation is platform dependent.

Shapes with which this shape cannot collide.

Unique identification number.

Returns the position vectors of this rectangle's vertices. The first vertex is the upper-right vertex at a rotation of 0. Vertices are ordered counter-clockwise.@return position vectors of the vertices

Volume. The volume is actually equivalent to this shape's area (SiMS is in 2D) and is used with this shape's density to calculate its mass.

Creates a new body out of this shape and the shapes of body b.

Creates a new body out of this shape and the shape s.
