Description

A convex polygon. It is assumed that the interior of the polygon is to the left of each edge.

Examples

Create a square box2d box

--create box2d physical object
local body = world:createBody{type = b2.STATIC_BODY}
local poly = b2.PolygonShape.new()
poly:setAsBox(100, 100)
local fixture = body:createFixture{shape = poly, density = 1.0, friction = 0.1, restitution = 0.2}

Methods

b2.PolygonShape.new creates a new polygon shape
b2.PolygonShape:set sets vertices
b2.PolygonShape:setAsBox set vertices to represent an oriented box

Events
