B2.ChainShape

Supported platforms:
Available since: Gideros 2012.2.2
Inherits from: b2.Shape

Description

A chain shape is a free form sequence of line segments. The chain has two-sided collision, so you can use inside and outside collision. Therefore, you may use any winding order. Connectivity information is used to create smooth collisions.

Note: the chain will not collide properly if there are self-intersections.

Examples

Create world bounds using ChainShape <source lang="lua"> local body = world:createBody{type = b2.STATIC_BODY} body:setPosition(0, 0) local chain = b2.ChainShape.new() chain:createLoop( 0,0, application:getContentWidth(), 0, application:getContentWidth(), application:getContentHeight(), 0, application:getContentHeight() ) local fixture = body:createFixture{shape = chain, density = 1.0, friction = 1, restitution = 0.3} </syntaxhighlight>

Methods b2.ChainShape.new b2.ChainShape:createChain creates a chain with isolated end vertices b2.ChainShape:createLoop creates a loop
