PARAM_MULTI_LINK

This element connects multiple source parameters to multiple target parameters: whenever one of the 'from' parameters changes, the 'to' parameters take the 'from' parameter value modified by the 'response_curve' and mux_function functions.

For simple scenarios (single to single param link) use PARAM_LINK or PARAM_CONNECTION.

Attributes brief detailed show all inherited

	Name	Description	Default
	from	Identifiers of the source parametersMandatory	empty
	to	Identifier of the destination parametersMandatory	empty
	mux_function	Function that convert the n input values to a single value, before being converted by the response_curve functionPossible values: 'min','max','-min','-max', '>','>=','<','<=','='. Since the format of the skin is xml, you need to use xml entities for special characters (for example write '&gt;' for '>')	max
	response_curve	Response curve: the value computed by the mux_function is modified by the curve before being set on the destination parameter	linear
	formula	Formula to transform the output of the mux function into the destination parameters. Acts as a custom response curveThis attributes overrides the "response_curve" attribute when set.The formula cannot reference external model data but 'x' (value of the 'from' param) and can only use built-in functions. If you want to reuse functions or parameters defined in the skin, please use the FORMULA_PARAM element and one or several PARAM_LINK instead	empty
	reverse	Reverse the response curveIf the curve is normalized, the transfer function of the link is:to=1-f(from),else it is:to=max-f(from)(f being the response curve)	'false'
	enabled	Enables or disables the link	'true'
	normalized	Links the normalized values of the parameters instead of the absolute valuesSet this parameter to true if you want to link the parameters relatively to their ranges, and not as absolute values. 'Normalized' values are set between 0 and 1, 0 corresponding to the minimum and 1 the maximum values of the parameters	'false'
Undocumented features
	trigger_min	When source param(s) value is lower than that, destination param(s) doesn't change.
	trigger_max	When source param(s) value is higher than that, destination param(s) doesn't change.
	trigger_condition	When this is set to "modify" the destination changes only when source param(s) are modified (not on window.loaded etc).
Common attributes
	id	Identifier of the elementThe id of an element has to be globally unique. Don't start with a digit for AngelScript compatibility.	empty

Examples

In comparison to PARAM_LINK this can quickly link a single source PARAM to multiple target params:

The power of PARAM_MULTI_LINK comes in handy when you need to link several sources to a single (or multiple) targets. Here's a playground script to see how it works with various mux_functions enabled.

When you have several input sources, you may get confused on how "<" and ">" mux_functions work: they compare parameters in order, so < gives 1 if A < B < C < D in the example below.

See more examples in PARAM_LINK and Params 101.
