Use emitter.lua to create particles in corona SDK. Effects like smoke can be achieved using this package.
SAMPLE USAGE 1:
local emitter = require("emitter")
local PARTICLES_PER_BURST = 20
local emit1 = emitter.createEmitter(<radiusRange>, <thickness>,<particleDuration>, <initAlpha>, <endAlpha>)
emitter.setColor(emit1, <red>, <green>, <blue>)
for i = 1,PARTICLES_PER_BURST do
emitter.emit(emit1, <group>, <x>, <y>) --emits single particle per call
end
SAMPLE USAGE 2: SMOKE
local emitter = require("emitter")
local mainGroup = display.newGroup()
local emit1
local PARTICLES_PER_BURST = 6
local i
local mem = display.newText("Memory :"..tostring(collectgarbage("count")), 0, 0, nil, 20)
local function init()
emit1 = emitter.createEmitter(180, 140, 1500, 0.05, 0)
emitter.setColor(emit1,255,255,0)
end
local function burst(event)
for i = 1,PARTICLES_PER_BURST do
emitter.emit(emit1, mainGroup, event.x, event.y)
end
mem.text = "Memory :"..tostring(collectgarbage("count"))
end
Runtime:addEventListener("touch", burst)
