The current value that this expression will ultimately write to (context specific)įor complex expressions, this evaluates the following statement and stops execution of the expression, returns the value computedĪrrow operator, for accessing data from a different entityįor repeating one or more commands 'n' timesįor skipping the rest of the set of statements of a loop/for_each iteration and moving to the next iteration NOTE: Nested ternary expressions without parentheses were incorrectly parsed before a Versioned Change was made to fix it (see 'Versioned Changes' below). Read-only storage provided by the game in certain scenarios Null coalescing operator, for handling missing variables or stale actor referencesĪ reference to a geometry named in the entity definitionĪ reference to a material named in the entity definitionĪ reference to a texture named in the entity definition Parentheses for expression term evaluation control We are hoping people will experiment with them and give us feedback, so we can move them into general usage. Some operators are under Experimental Molang Features at the moment in the list below. 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.

In complex cases, multiple sub-expressions are each terminated with a semicolon. In simple cases, the terminating is omitted and the expression result is returned.

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. The language structure is largely based on simple 'C' language family style syntax. Now they evaluate as A ? B : (C ? D : E). Previously nested conditional expressions like A ? B : C ? D : E would evaluate as (A ? B : C) ? D : E. For example ''text' + 1' will now cause a content error.įixed conditional (ternary) operator associativity. Also fixed normalization logic in that query to go from 1 down to 0 instead of 0 up to 1.Īdded some new error messages for invalid expressions which previously ran with probably unexpected results. (Not actually a Versioned Change)įixed em_remaining_use_duration conversion from ticks to seconds (multiplied by 20 instead of dividing). Initial support for Versioned Changes added. Versioned Change Versions Pack min_engine_version Any Versioned Change with a version less than or equal to that version number will be in effect. 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. This is a list of the Versioned Changes that have been added, along with the corresponding game version. Molang Versioned Change versions apply to each expression separately, so it's possible to have different versions active if multiple packs are loaded. This allows for changes to how Molang works without breaking existing content. 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. 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.

Windows installer will also create a directory 'MathMod-4.1(Win64)' in the Desktop folder (with three JSON files) and will use it as it's working directory so It can then be used, for example, to fine-tune MathMod's configuration.Ĥ) Four new MathMod scripts, for a total of 341 integrated scripts.ĥ) Five Video Tutorials to quickly learn how to use some MathMod features. The decimal separator is set by the field 'DotSymbol' in the 'mathmoconfig.js' file.ģ) By default MathMod will use the Fusion/Dark theme but you can define your own style/theme with the 'mathmoconfig.js' file. 1) Add tools to create/edit/delete sliders without having to edit the script manually: see this youtube video Ģ) Localization Support for decimal separators as Comma (,) or Point (.)
