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}
