MovieClip

Supported platforms:
Available since: Gideros 2011.6
Inherits from: Sprite

Description

The MovieClip class inherits from the following classes: Sprite > EventDispatcher.

The MovieClip class is used to create static timedlined animations. The timeline parameters are given as an array.

Each array element specifies one timeline element and consists of: the starting frame (frame numbers start from 1), the ending frame, a sprite and an optional tweening parameters.

When a MovieClip object finishes playing (by reaching its final frame or a frame with stop action), it dispatches an Event.COMPLETE event.

The following properties can be tweened:

• x
• y
• rotation
• scale
• scaleX
• scaleY
• alpha
• anchorX
• anchorY

Additionally MovieClip uses a function to tween properties. If you override the default tween function then you can tween this parameter too. The following easing functions can be used:

• "inBack"
• "outBack"
• "inOutBack"
• "inBounce"
• "outBounce"
• "inOutBounce"
• "inCircular"
• "outCircular"
• "inOutCircular"'
• "inCubic"
• "outCubic"
• "inOutCubic"
• "inElastic"
• "outElastic"
• "inOutElastic"
• "inExponential"
• "outExponential"
• "inOutExponential"
• "linear"
• "inQuadratic"
• "outQuadratic"
• "inOutQuadratic"
• "inQuartic"
• "outQuartic"
• "inOutQuartic"
• "inQuintic"
• "outQuintic"
• "inOutQuintic"
• "inSine"
• "outSine"
• "inOutSine"

Examples

-- construct a 100 frame animation where x coordinate of sprite tweens from 0 to 200 linearly
local mc = MovieClip.new{
	{1, 100, sprite, {x = {0, 200, "linear"}}}
}

-- construct a 100 frame animation where x coordinate of sprite is 50 (constant) and 
-- y coordinate of sprite tweens from 50 to 150 by using inBounce function
local mc = MovieClip.new{
	{1, 100, sprite, {x = 50, y = {50, 150, "inBounce"}}}
}

-- construct a 200 frame animation where sprite1 and sprite2 tweens differently
-- here sprite1 is visible between frames [1, 150]
-- and sprite2 is visible between frames [100, 200]
local mc = MovieClip.new{
	{1, 100, sprite1, {x = {0, 200, "linear"}}},
	{50, 150, sprite1, {y = {0, 100, "linear"}, alpha = {0, 1, "easeOut"}}},
	{100, 200, sprite2, {x = {0, 200, "linear"}}},
}

-- construct a looping 6 frame animation where each frame is a different sprite
local mc = MovieClip.new{
	{1, 1, frame1},	
	{2, 2, frame2},	
	{3, 3, frame3},	
	{4, 4, frame4},	
	{5, 5, frame5},	
	{6, 6, frame6},
}
mc:setGotoAction(6, 1)	-- if the animation reaches frame 6 then go to frame 1
						
-- construct a looping 6 frame animation playing 5 times slower than the previous example
local mc = MovieClip.new{
	{1, 5, frame1},	
	{5, 10, frame2},	
	{11, 15, frame3},	
	{16, 20, frame4},	
	{21, 25, frame5},	
	{26, 30, frame6},
}
mc:setGotoAction(30, 1)	-- if the animation reaches frame 30 then go to frame 1

Methods MovieClip.new creates a new MovieClip object MovieClip:clearAction clears the action at the specified frame MovieClip:getFrame gets the current frame MovieClip.getTweenFunction retrieves the specified tween/easing function MovieClip:gotoAndPlay goes to the specified frame and starts playing MovieClip:gotoAndStop goes to the specified frame and stops MovieClip:play starts playing the movie clip MovieClip:isPlaying returns whether or not current clip is playing MovieClip:setGotoAction sets a "go to" action to the specified frame MovieClip:setReverseAction sets a "reverse" action to the specified frame MovieClip:setStopAction sets a "stop" action to the specified frame MovieClip:stop stops playing the movie clip
