Animation Subsystem</h1>
<p>The <a class="el" href="namespace_animation.html">Animation</a> system provides an interface to play, pause and seek nax3 animation clips, which can be extracted either from an asset file at import, or constructed by some tool. The animation system also provides support for animation events - triggers which should play when an animation arrives at a certain frame. Animations are played as a sequence timeline with several tracks, each track corresponding to a single animation clip for a certain time. The tracks have weights attached to them, and can also be provided a skeleton mask. This allows for animations to play simultaneously, blend together, and mask out certain parts of the skeleton we wish to not animate for that track.</p>
<p>An animation resource is split up into several clips, each clip being a sequence of transforms, a duration, begin and end interpolation modes.</p>
<p>To construct an instance of an animation resource in <a class="el" href="namespace_nebula.html">Nebula</a>, we need to run:</p>
<div class="fragment"><div class="line">CoreAnimation::AnimResourceId <span class="keywordtype">id</span> = <a class="code hl_function" href="namespace_resources.html#a06149171c66844225680ba6cdadbd323">Resources::CreateResource</a>()</div>
<div class="ttc" id="anamespace_resources_html_a06149171c66844225680ba6cdadbd323"><div class="ttname"><a href="namespace_resources.html#a06149171c66844225680ba6cdadbd323">Resources::CreateResource</a></div><div class="ttdeci">Resources::ResourceId CreateResource(const ResourceName &res, const Util::StringAtom &tag, std::function< void(const Resources::ResourceId)> success=nullptr, std::function< void(const Resources::ResourceId)> failed=nullptr, bool immediate=false, bool stream=true)</div><div class="ttdef"><b>Definition</b> resourceserver.h:353</div></div>
</div><!-- fragment --><p>Providing CreateResource with a file with the extension .nax3 and it will load as an animation. This means we have now loaded all the animation data and handle <code>id</code> will hold on to it. Animations are evaluated by interpolating between frames, and there are two functions (which can be passed to the job system), that provides this functionality. The following code shows how we can evaluate animation samples on a job, clip being the clip index we want to evaluate:</p>

</div><!-- fragment --><p>This code is taken from <a class="el" href="class_characters_1_1_character_context.html" title="Assumes control over the character animation functionalities of a model if it contains a character de...">Characters::CharacterContext</a> and slightly modified to make it simpler. What we are doing is we are setting up a duration, how much time there is between animation ticks, a temporary buffer (called a scratch buffer) to hold intermediate data in the job. We then prepare the job context with all this information, and schedule it to execute. outSamplesPtr will then contain the result of this job when the job is finished.</p>
<p>Using <a class="el" href="class_core_animation_1_1_anim_sample_buffer.html" title="Stores the result of an animation sampling operation, stores samples key values and sample-counts whi...">CoreAnimation::AnimSampleBuffer</a> (which is outSamplesPtr in the above example), we can then figure out how many <a class="el" href="struct_math_1_1vec4.html" title="A 4D vector.">Math::vec4</a> elements we have, such that we can intelligently make decisions about how to use this data to perform transformations. In most cases, a single joint contains 3 <a class="el" href="struct_math_1_1vec4.html" title="A 4D vector.">Math::vec4</a>, because we have a scale, rotation and transformation vector, which when combined will be our final matrix. </p>
