<h1><p id="Why Does Molang Exist?">Why Does Molang Exist?</p></h1>

Molang is a simple expression-based language designed for fast, data-driven calculation of values at run-time, and with a direct connection to in-game values and systems.  Its focus is to enable low-level systems like animation to support flexible data-driven behavior for both internal and external creators, while staying highly performant.</br><a href="#Index">Back to top</a><br><br>

<h1><p id="Lexical Structure">Lexical Structure</p></h1>

The language structure is largely based on simple 'C' language family style syntax.  An expression can be made of either one simple value or math calculation, or can be made of several sub-expressions where more complicated code is required.</br></br> In simple cases, the terminating `;` is omitted and the expression result is returned. </br> In complex cases, multiple sub-expressions are each terminated with a semicolon `;`.  Complex expressions evaluate to `0.0` unless there is a `return` statement, in which case the evaluated value of the `return`'s sub-expression will be returned out of the current scope.</br><h1><p id="Case Sensitivity">Case Sensitivity</p></h1>

All things in Molang are case-INsensitive, with the exception of strings, which maintain the case provided.</br><a href="#Index">Back to top</a><br><br>

<h1><p id="Operator Precedence">Operator Precedence</p></h1>

Molang Operators follow this order to determine which thing is evaluated first when no parentheses are used. This should match the behavior of C or C++. Operators that are higher in this table are evaluated first, while operators on the same row are evaluated with the same priority. When operators have the same priority, they are evaluated left-to-right, except for the Ternary conditional operator, which is evaluated right-to-left. Using parentheses will allow direct control of order of evaluation, and is recommended for more complex expressions. </br><h2></h2>

<h1><p id="Variables">Variables</p></h1>

There are three variable lifetimes a variable may belong to: Temporary, Entity, and Context:</br>- Temporary variables (eg: `temp.moo = 1;`) are read/write and valid for the scope they are defined in, as per C rules.  For performance reasons their lifetime is global to the current expression execution and may return a valid value outside of the outermost scope they are defined in for an expression.  Be careful in complex expressions.  We will be adding content errors for invalid accesses as soon as possible.</br>- Entity variables (eg: `variable.moo = 1;`) are read/write and store their value on the entity for the lifetime of that entity.  Note that these are currently not saved, so quitting and reloading the world will re-initialize these.  In the same way, if the entity is despawned, any variables on the entity will be lost.</br>- Context variables (eg: `context.moo`) are read-only and specified by the game in certain situations. Details on what variables are specified and when will be available in the documentation of the area where that Molang expression is used (such as behaviors defining what context variables they expose).</br><a href="#Index">Back to top</a><br><br>

<h1><p id="Values">Values</p></h1>

<h2></h2>

</br>- All numerical values are floats.</br>- Boolean values such as actor flags are converted and stored as a float value of either 0.0 or 1.0 for values of false or true respectively.</br>- For boolean tests, a float value equivalent to 0.0 is false, and anything not equal to 0.0 is true.</br>- For array indices, floats are C-style-cast to ints, and clamped at zero for negative values or wrapped by the array size for large values.</br>- Other supported types are:</br><a href="#Index">Back to top</a><br><br>

<h1><p id="Query Functions">Query Functions</p></h1>

Query functions (eg: `query.is_baby` or `query.is_item_equipped('main_hand')`) allow expressions to read game data.  If a query function takes no arguments, do not use parentheses. Otherwise, use parentheses and separate arguments with commas. For a full list of query functions, see below.</br><a href="#Index">Back to top</a><br><br>

Note that structures can be arbitrarily deep in their nesting/recursiveness.  That said, it is recommended that you don't copy full structures inside other structures to avoid exploding memory, and not making structures too deep as there is a slight performance cost for each layer.</br><a href="#Index">Back to top</a><br><br>

<h1><p id="Strings">Strings</p></h1>

Strings in Molang are surrounded by single quotes, eg: `'minecraft:pig'` or `'hello world!'`. An empty string is defined as two consecutive single quotes.  String operations only support `==` and `!=` at this time.</br>Note: strings don't support the ' character as there is no support for escape characters at this time.</br><a href="#Index">Back to top</a><br><br>

<h2></h2>

Some return values of query function, or values stored in temp/entity/context variables can be a reference to another entity.  The `->` operator allows an expression to access variables or run queries on that entity.  For example, the example below will find all pigs within four meters of the current entity (including itself if it's a pig), and increment a variable `v.x` on itself if the block immediately above each pig is flammable (such as an oak button) :</br>Note that in the case where the left-hand side of the `->` operator has an error (value is null, the entity was killed previously, or some other issue), the expression will not evaluate the right-hand side and will return 0. This implementation style was a choice between performance and not requiring content creators to overly worry about checking for potentially bad values everywhere.</br></br><h3></h3>

In general, variables of a mob are considered private to that mob and cannot be accessed by another.

<h1><p id="Conditionals">Conditionals</p></h1>

The conditional '?' operator allows for two convenient ways to implement simple branching logic.</br> The first way is to use '?' by itself to conditionally execute part of an expression, for example `A ? B`. The part after the '?' is only run if the part before it evaluates to a true boolean.</br> The second way is to use '?' with a ':' as a 'conditional ternary', for example `A ? B : C`. If the part before the '?' is evaluated as true, the part before the ':' is returned. Otherwise the part after is returned.</br> NOTE: Nested ternary expressions without parentheses were incorrectly parsed before a Versioned Change was made to fix it (see 'Versioned Changes' below).</br><h2></h2>

Sometimes you want to execute an expression multiple times.  Rather than copy-pasting it a bunch, you can use `loop(<count>, <expression>);`.  We have placed some arbitrary restrictions on these for safety for now. The maximum loop counter is (as of this document being written) 1024.

<h1><p id="for_each">for_each</p></h1>

`query.get_nearby_entities` (see below) returns an array of entities.  In order to iterate through them, you can use the following new built-in function `for_each`.  It takes three parameters: `for_each(<variable>, <array>, <expression>);`  The variable can be any variable, either a `temp.` or `variable.`, although I'd recommend using `temp.` to not pollute the entity's variable space.  The expression is any Molang expression you want to execute for each entry in the array)</br><h2></h2>

<h1><p id="?? Null Coalescing Operator">?? Null Coalescing Operator</p></h1>

Similar to how the null-coalescing operator works in C#, one can now reference a variable that may or may not exist without seeing a content error.  If it doesn't, you can now provide a default value to use.  Previously, if a variable didn't exist you would get a content error.  This was to make sure variables were always initialized correctly to avoid uninitialized variable bugs.  Unfortunately this then required initialize scripts, or in some cases some complex work-arounds to make sure variables were initialized.  Now, if you know a variable won't be initialized in the first run of a script, you can use the following:</br><h2></h2>

<h3></h3>
<br / ><textarea readonly="true" cols="40" rows="2">
variable.x = (variable.x ?? 1.2) + 0.3;
</textarea> </br>
<a href="#Index">Back to top</a><br><br>

</br>This will use the value of `variable.x` if it is valid, or else 1.2 if `variable.x`:</br>- has not yet been initialized</br>- is a reference to a deleted entity</br>- is an invalid reference</br>- holds an error</br></br>Note that the `??` operator will work with `variable.`s, `temp.`s, and `context.`s that hold numbers or entity references, but not resources such as materials, textures, or geometries (as those must exist and be valid else it's a content error).  If the first argument would result in something that can't be resolved, it will return the second argument.</br></br>_Reminder: the standing rule of thumb in Molang is that if something would error or be a bad value, it is converted to 0.0 (and generally throw a content error on screen in non-publish builds.  Note that content errors may prevent uploading content to the Marketplace, so please ensure expressions aren't going to do bad things such as dividing by zero)._</br><a href="#Index">Back to top</a><br><br>

<h1><p id="Simple vs Complex Expressions">Simple vs Complex Expressions</p></h1>

<h2></h2>

A simple expression is a single statement, the value of which is returned to the system that evaluated the expression.  eg:</br><h3></h3>
<br / ><textarea readonly="true" cols="33" rows="2">
math.sin(query.anim_time * 1.23)
</textarea> </br>
<a href="#Index">Back to top</a><br><br>

A complex expression is one with multiple statements, each ending in a ';'.  Each statement is evaluated in order.  In the current implementation, the last statement requires the use of the return keyword and defines the resulting value of the expression.  eg:</br><h3></h3>
<br / ><textarea readonly="true" cols="45" rows="4">
temp.moo = math.sin(query.anim_time * 1.23);
temp.baa = math.cos(query.life_time + 2.0);
return temp.moo * temp.moo + temp.baa;
</textarea> </br>
<a href="#Index">Back to top</a><br><br>

Note that in a simple expression, `;` is not allowed, whereas in a complex expression, each statement requires a `;` including the last.  Also, note that if you don't `return` a value from a complex expression, the expression will evaluate to 0.0.</br><a href="#Index">Back to top</a><br><br>

These are numerical operations to control which animations are playing and how to animate bones.  "variable.variable_name" and "query.function_name" refer to the entity currently being rendered.

There are a few different kinds of expressions here, where context implies what is allowed.  As with animations, the entity accessors refer to the current entity, however depending on the context one also has access to materials, textures, and geometries.  There are two sections in a render controller:</br>-Array definitions (optional)</br>-Resource usage (required)</br>The array definition section allows you to create arrays of resources by resource type if you so desire.  These can then be referenced in the resource usage section.</br><h2></h2>

<h2><p id="Array Expressions">Array Expressions</p></h2>

For each of the three resource types (materials, textures, and geometry), you can define an array of resources.  The name of the resource is the nice-name from the definition file.  Using materials as an example:</br><h3></h3>

<h4></h4>
<br / ><textarea readonly="true" cols="93" rows="12">

  },
</textarea> </br>
<a href="#Index">Back to top</a><br><br>

Note that all elements of an array must be of the same type.  eg: a texture array must only contain textures.</br></br>An array can reference any combination of zero or more arrays (including duplicates if desired) and/or zero or more materials (again, including duplicates if you like), and you can have as many arrays as you like, each with as many elements as you like.  If an array includes arrays in its members, they do not need to be the same length.  When indexing into an array in the resource usage section, you use numerical expressions.  If the resulting number is negative, it will use zero as the index.  Any non - negative index will converted to an integer, and will wrap based on the size of the array:</br><h4></h4>

<h3><p id="Geometry">Geometry</p></h3>

The geometry section specifies which geometry to use when rendering.

Note that a geometry can be arbitrarily complex using any number of bones and polygons.</br><a href="#Index">Back to top</a><br><br>

<h3><p id="Materials">Materials</p></h3>

The materials section specifies how to map what material to what bone of the geometry.  A single material is mapped to a whole bone.  Material expressions are evaluated in the order listed.  The first part of each statement is the name of the model part to apply the material to, and the second part is the material to use.  The model part name can use * for wild - card matching of characters.  For example: </br><h4></h4>

- This will start by applying Material.default to all model parts.</br>- Next, it will set the material on a model part named "TailA" to the result of the expression "Array.hairColors[variable.hair_color]".  This will look up some previously created variable on the entity named hair_color and use that to index into a material array called "array.hair_colors" defined in this render controller.  This will overwrite the Material.default material set in the line above.</br>- Third, it will look up the same material as the expression is identical, and apply it to the "Mane" model part.</br>- Lastly, if will find any model part starting with, ending with, or containing "Saddle" (case sensitive) and change its material to either material.leather_saddle or material.iron_saddle depending on the previously set entity variable variable.is_leather_saddle.</br><a href="#Index">Back to top</a><br><br>

<h1><p id="Versioned Changes">Versioned Changes</p></h1>

Molang uses the `"min_engine_version"` from the `manifest.json` of the resource or behavior pack that contains each Molang expression to determine which version of the rules to apply. This allows for changes to how Molang works without breaking existing content. </br></br>Molang Versioned Change versions apply to each expression separately, so it's possible to have different versions active if multiple packs are loaded. </br></br>This is a list of the Versioned Changes that have been added, along with the corresponding game version. </br></br>To know which Versioned Changes are in effect, look at the `"min_engine_version"` of the `manifest.json` of the resource or behavior pack that contains your Molang expression. Any Versioned Change with a version less than or equal to that version number will be in effect. </br><h1><p id="Versioned Change Versions">Versioned Change Versions</p></h1>
