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.

<ul>
<li>*Note:** The chain will not collide properly if there are self-intersections.</li>
</ul>

Examples

Create world bounds using ChainShape

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}

Methods

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