Shape

Shape

This class makes a body tangible to collision detection and response.Without it,the body will not be able to interact with other bodies.

Constructor

new Shape(vertices)

Source:
Parameters:
Name Type Description
vertices Array.<Vector2> The vertices of the shape in local space coordinates.
