<h3>Parameters</h3>
|

|
|
<ul class="parameters">

<li><span class="parameter">__name</span>
|
||
|
|
<span class="types"><span class="type">string</span></span>
|
||
|
|
<br/>
|
||
|
|
The name of the animation, this is also used as the key for the animation.
|
||
|
|
</li>
|
||
|
|
<li><span class="parameter">__startFrame</span>
|
||
|
|
<span class="types"><span class="type">integer</span></span>
|
||
|
|
<br/>
|
||
|
|
This is the first frame of this animation in the imagetable/spritesheet
|
||
|
|
</li>
|
||
|
|
<li><span class="parameter">__endFrame</span>
|
||
|
|
<span class="types"><span class="type">integer</span></span>
|
||
|
|
<br/>
|
||
|
|
This is the final frame of this animation in the imagetable/spritesheet
|
||
|
|
</li>
|
||
|
|
<li><span class="parameter">__next</span>
|
||
|
|
<span class="types"><span class="type">string</span></span>
|
||
|
|
<br/>
|
||
|
|
By default, animation states will loop, but if you want to sequence an animation, enter the name of the next state here.
|
||
|
|
</li>
|
||
|
|
<li><span class="parameter">__loop</span>
|
||
|
|
<span class="types"><span class="type">boolean</span></span>
|
||
|
|
<span class="default">= <span class="value">true</span> (default)</span>
|
||
|
|
<br/>
|
||
|
|
If you want a state to "freeze" on its final frame, instead of looping, enter <code>false</code> here.
|
||
|
|
</li>
|
||
|
|
<li><span class="parameter">__onComplete</span>
|
||
|
|
<br/>
|
||
|
|
This function will run when this animation is complete. Be careful when using this on a looping animation!
|
||
|
|
</li>
|
||
|
|
<li><span class="parameter">__frameDuration</span>
|
||
|
|
<span class="types"><span class="type">integer</span></span>
|
||
|
|
<span class="default">= <span class="value">1</span> (default)</span>
|
||
|
|
<br/>
|
||
|
|
This is the number of ticks between each frame in this animation. If not specified, it will be set to 1.

<p> When attached to a NobleSprite, this is called by <code>NobleSprite:draw()</code> when added to a scene. For non-NobleSprite sprites, put this method inside your sprite's <code>draw()</code> method, or inside <a href="../classes/NobleScene.html#noblescene:update">NobleScene:update</a>.

Use this for objects or sprites that you want to control outside of update loops, such as score counters, flipbook-style objects that respond to player input, etc.
