<h1><p id="Animation Controllers">Animation Controllers</p></h1>
Animation controllers decide which animations to play when. Each controller contains a list of states that play one or more animations, each of which can be blended by a Molang expression if so desired. Controller files are stored as JSON in the animation_controllers folder</br><h2></h2>

<h1><p id="States">States</p></h1>
A state defines a group of animations to process (each of which can have it's own blend value). Each state has an optional variables section, listing any number of variables that referenced animations can use. Each state also has one or more animations, using the name given in the entity's definition json.</br><h2></h2>
<h2><p id="State Variables">State Variables</p></h2>
Variables are either set by the game or by a user defined script that can be found in the entity definition json found in definitions/entity/<entity_name>.json. Variables have their value set by a Molang Expression. They can also have their value remapped via a linearly-interpolated curve.</br><h3></h3>
<h3><p id="For Example:">For Example:</p></h3>
This defines a controller with a single state. It will create a variable `variable.ground_speed_curve` that lives on the entity only while processing the animation controller for that frame. It will take the value of `query.ground_speed`, then remap it to between 0.2 and 0.7 based on the value of `query.ground_speed` going from 0.0 to 1.0It will play one animation walk that will blend from 0.0 to 1.0 as the ground speed increases from stopped to 2.3 m/s. The remap curve can have any number of entries. The animation controller will then play the entity-referenced `wiggle_nose` animations, followed by the `walk` animation, scaling the latter by the value of `variable.ground_speed_curve`</br><h4></h4>

<h2><p id="User-Defined Script Example">User-Defined Script Example</p></h2>
This script will set foo to the result of the sine of query.life_time to later be used in the animation or animation controller.</br></br>Note: "pre_animation" tells the script to figure out the values of those variables once a frame, before animation occurs, so that the animation can use those values in their own formulas. If a variable didn't exist, it will create a new variable and its default value will be 0.0</br><h3></h3>
Note in this example that because foo is equal to a sin wave, that its values will range from -1 to 1. This means that you will have a period from 0 to -1 to 0 where only "base_pose" will play and then an equal amount of time where Walk will play on top of base_pose as foo goes from 0 to 1 back to 0. Base_pose will have a blend value of 1.0.</br><h4></h4>

One needs to be able to control how animations are played, when, and how they interact with other animations. to group animations While a lot of this can be managed in the entity definition `scripts/animate` section, animation controllers give you the functionality of a state machine into states and control them as a block. Animations in an animation controller state can be animation controllers themselves, allowing for arbitrarily complex animation hierarchies.</br><h3></h3>

<h3><p id="Note">Note</p></h3>
Note: the walk animation for pig is the same for cows and sheep, and thus uses animation.quadruped.walk instead of defining its own. This means you will not see the move animation in the pig.json animation file either. If you would like to make a custom pig walk you can change this line to point to your custom animation.</br></br>Animations are specified as a short name, followed by their full resource name. The short name is used in animation controllers and the `scripts/animate` list, while the long name is used in the animations file.</br></br>In the `scripts/animate` section, you list the animations to play and in which order.

<h1><p id="Upgrade from v1.7 Beta to v1.8">Upgrade from v1.7 Beta to v1.8</p></h1>
There have been few changes as we clean things up based on feedback and as we push the tech along the road map.To upgrade previous scripts, you'll want to do the following steps to all of your Molang scripts in the order listed:</br>1) entity.flags.foo --> query.foo</br>2) entity.member.foo --> query.foo</br>3) entity.foo --> variable.foo</br>4) params.foo --> global.foo</br>5) The general rule is that 'query' represents read-only values from the entity the script is running on, and 'variable' represents read-write data created by the user.</br>6) We've adopted snake_case for all names of things. You are welcome to use upper-case letters if you wish as we are case-insensitive, however we recommend snake_case in general.</br>7) Several variables previously set on mobs have been changed to use the query.foo format. Look through the updated list below to see what has been added and changed.</br><a href="#Index">Back to top</a><br><br>
<h1><p id="Upgrade from v1.8 Beta to v1.10">Upgrade from v1.8 Beta to v1.10</p></h1>
The three major changes with 1.10 are</br>- the ability to have animations reference other animations in an arbitrarily deep hierarchy.</br>- the parameters section of animation controllers has been replaced with the `variables` section.</br>- in the entity definition file, animation controllers are now listed in the `animations` section, and a `scriptsnimate` section has been added to define which root animations to play.</br>The v1.8 file format is backwards-compatible with v1.10 so you don't _need_ to change anything (although we recommend refactoring your files in the spirit of v1.10 as there is a slight performance win with the new format, as well as it being simpler to understand.</br><a href="#Index">Back to top</a><br><br>

A key frame defines two values for a channel-specific transform to a specific bone at a specified time, one as time approaches the key frame time, and the second from that key frame time onwards.</br>As such, when interpolating between two key frames, one can define the slope of the animation curve in either a continuous or discontinuous manner.</br><h1><p id="Interpolation">Interpolation</p></h1>
Currently only linear interpolation is supported. Key frame "pre" and "post" settings allow control of the interpolation curve at any key frame.</br><h2></h2>

This example spins the bone "head" around the y axis 1 rotation in 1 second.</br>Note that because interpolation is linear, at .25 seconds the head will be rotated to 90 degrees.</br><h3></h3>

Discontinuous just means that there won't be a smooth transition between key frames. It is useful if you want something to happen immediately.</br>This example scales the bone "head":</br>1.

At 0.5 seconds, the bone will instantly scale up to 2 times its normal size</br>3. From 0.5 to 1 second ("post"), the bone will re-scale back to its normal size of scale of 1 in all dimensions</br></br>Note In the larger example above of the file format, "pre" and "post" can also be defined by a Molang expression that calculates that value at runtime, allowing you to have a mathematically defined curve instead of being purely linear.</br><h3></h3>
