Class: MovieClip

Description

Creates a new MovieClip object. After constructing the MovieClip object, it starts playing. You don't need to call MovieClip:play. 

MovieClip.new({timeline},holdWhilePlaying)

Parameters

timeline: (table) array of timeline elements
holdWhilePlaying: (bool) keep a reference to itself while it is playing optional, default=false

Example

Frame animations 1 

--load frames
local frames = {}
local bmp
for i = 1, 6 do
	bmp = Bitmap.new(Texture.new("animation/ball"..i..".png", true))
	bmp:setAnchorPoint(0.5, 0.5)
	frames[#frames+1] = bmp
end

--arrange frames
local ballAnimation = MovieClip.new{
	{1, 5, frames[1]},
	{6, 10, frames[2]},
	{11, 15, frames[3]},
	{16, 20, frames[4]},
	{21, 25, frames[5]},
	{26, 30, frames[4]},
	{31, 35, frames[6]},
	{36, 40, frames[4]},
	{41, 45, frames[5]},
	{46, 50, frames[4]},
	{51, 55, frames[6]},
	{56, 60, frames[4]},
	{61, 65, frames[5]},
	{66, 70, frames[4]},
	{71, 75, frames[6]},
	{76, 80, frames[3]},
	{81, 85, frames[2]},
	{86, 150, frames[1]}
}

--loop animation
ballAnimation:setGotoAction(150, 1)

--start playing
ballAnimation:gotoAndPlay(1)

ballAnimation:setPosition(160, 240)
stage:addChild(ballAnimation)

Frame animations V2, animating with 2 movieclips 

-- first we create the anims for the player
local frames = {}
local imgnumstartat, imgnumendat = 1, 20 -- image name sequence (eg.: image004.jpg, image005.jpg, ...)
for i = 1, imgnumendat-imgnumstartat+1 do
	local iter = imgnumstartat+i-1
	if iter < 10 then
		frames[#frames+1] = Bitmap.new(Texture.new("gfx/hero/Jones_base_000"..(imgnumstartat+i-1)..".png", true))
	elseif iter < 100 then
		frames[#frames+1] = Bitmap.new(Texture.new("gfx/hero/Jones_base_00"..(imgnumstartat+i-1)..".png", true))
	elseif iter < 1000 then
		frames[#frames+1] = Bitmap.new(Texture.new("gfx/hero/Jones_base_0"..(imgnumstartat+i-1)..".png", true))
	end
	frames[i]:setAnchorPoint(0.5, 0.5)
end -- print(#frames)

local anims = {}
local timing = 8
for i = 1, #frames do
	anims[i] = {(i-1)*timing+1, i*timing, frames[i]}
end -- print((#frames-1)*timing+1, #frames*timing)
--print(#anims) --> 20

-- add anim frames
local mc_jones = MovieClip.new(anims, true)
mc_jones:setGotoAction(14*timing, 9*timing)
mc_jones:gotoAndPlay(9*timing)

-- key down event
stage:addEventListener(Event.KEY_DOWN, function(e)
	if e.keyCode == KeyCode.F then -- jones idle
		mc_jones:setGotoAction(8*timing, 1)
		mc_jones:gotoAndPlay(1)
	elseif e.keyCode == KeyCode.G then -- jones idle2
		mc_jones:setGotoAction(14*timing, 9*timing)
		mc_jones:gotoAndPlay(9*timing)
	elseif e.keyCode == KeyCode.H then -- jones idle3
		mc_jones:setGotoAction(20*timing, 15*timing)
		mc_jones:gotoAndPlay(15*timing)
	end
end)

-- then we move the player using another movieclip
local timing2 = 500
local mc2 = MovieClip.new{
	{1, timing2/2, mc_jones, {x={160, 240, "inOutExponential"}}},
	{timing2/2+1, timing2, mc_jones, {x={240, 160, "inOutExponential"}}},
}

mc2:setGotoAction(timing2, 1)
mc2:setPosition(160, 240)
stage:addChild(mc2)
