B2.ParticleSystem:createParticleGroup

Available since: Gideros 2011.6
Class: b2.ParticleSystem

Description

Creates a group of multiple particles with same properties, that can be defined in table with:

• flags
• groupFlags
• position
• angle
• linearVelocity
• angularVelocity
• color
• alpha
• strength
• shape
• lifetime

b2.ParticleSystem:createParticleGroup(particleGroupDef)

Parameters

particleGroupDef: (table) table with particle group data

Example

require "liquidfun"
local world = b2.World.new(0, 9.8)
local shape = b2.PolygonShape.new()
shape:setAsBox(128, 128)
local ps = world:createParticleSystem( { radius = 16 } )
ps:setTexture(Texture.new("gfx/myparticle.png"))
stage:addChild(ps)
ps:createParticleGroup( { shape = shape, position = { x = 128, y = 128}, color = 0xffffff, alpha=1, flags=b2.ParticleSystem.FLAG_VISCOUS } )
