Description

Defines particle system in box2d world using LiquidFun.

Examples

Simple particle system example

-- create world
local world = b2.World.new(0, 9.8)

local ps1 = world:createParticleSystem({ radius=5})
ps1:setTexture(Texture.new("Bubble.png"))
stage:addChild(ps1)

ps1:createParticleGroup({shape=shape2,
	position={x=500,y=250},
	color = 0xFF0000,
	alpha=1,
	flags=0
})

ps1:createParticleGroup({shape=shape1, 
	position={x=400,y=50},
	color = 0x0000FF,
	alpha=1,
	flags=0
})

-- step the world and then update the position and rotation of sprites
local function onEnterFrame()
	world:step(1/60, 8, 3)
end

stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)
