Documentation

Commands

play

$(".testButton").spriteAnimation('play');

Plays the animation sequence forward.

rewind

$(".testButton").spriteAnimation('rewind');

stop

$(".testButton").spriteAnimation('stop');

Stops the animation sequence where it is.

reset

$(".testButton").spriteAnimation('reset');

Parametric commands

Commands that require parameters should be set as properties on objects. Commands can be issued in the same object as option updates.

gotoFrame

$(".testButton").spriteAnimation({gotoFrame:0});

Sets the current frame of the animation to the integer value

Special parameter 'end' goes to the last frame of the animation. Useful for reversing.

gotoFrameRatio

$(".testButton").spriteAnimation({gotoFrameRatio:0});

Takes floats 0-1. Sets the current frame of the animation to the frame at the ratio of the total animation. Useful for tweening.

Options

src

Image source url. If not provided, the script tries to use the element's background-image or the <img src>.

{ src: "filmstrip.png" }

firstFramePosition

Position of the first frame in sequence. (allows you to put multiple sequences in one image)

// Object with x and y parameters. 
{ firstFramePosition: {x:0, y:0} }

orientation

Direction to look for subsequent frames.

// String, either 'x' or 'y'. 
{ orientation: "x" }

frameWidth

Width of the frame in px. Defaults to the css width of the element.

// Number 
{ frameWidth: 25 }

frameHeight

Height of the frame in px. Defaults to the css width of the element.

// Number 
{ frameHeight: 25 }

frameSpacing

Spacing between frames in px

// Number 
{ frameSpacing: 0 }

frameRate

Frames per second

// Number 
{ frameRate: 60 }

length (required)

Number of frames in the sequence.

// Number 
{ length: 25 }

loop

Loop on complete.

// Boolean 
{ loop: false }

onComplete

Callback on complete.

// Function 
{ onComplete: null }

command

Adds a command to execute after the settings have been set

// Takes any String command from the Commands section
{ command: null }

Sequences

Sequences can be added via the addSequence or addSequences options. If no sequences are explicitly defined, a default sequence labeled 'a' is created transparently using the main options object.

Sequence objects can contain the following parameters, but default to the same values as above if they are omitted:

{ addSequences: {
    'myLabel':{
        duration:25,
        length:false,
        firstFramePosition: {x:0, y:0},
        reverse: false,
        onComplete: null
    }
}

or

{ addSequence: {
    label: 'myLabel',
    length:25,
    loop:false,
    firstFramePosition: {x:0, y:0},
    reverse: false,
    onComplete: null
}

Note the inclusion of a label in an object passed to addSequence is required, while the object key is used as the label in addSequences

setSequence

Used to change the sequence

//String
{ setSequence: 'myLabel' }

gotoAndPlay

Shortcut method that sets a new sequence and immediately starts playing it.

{ gotoAndPlay: 'myLabel' }

Is the same as

{ setSequence: 'myLabel',
    command: 'play'
}

Events

spriteAnimation:complete

jquery.spriteAnimation fires spriteAnimation:complete events on the hosting jquery object whenever any sequence completes. It also fires a spriteAnimation:complete:[sequence label] event when labeled sequences complete.
