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=b2.ParticleSystem.FLAG_COLOR_MIXING | b2.ParticleSystem.FLAG_POWDER,
})
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
