MHuiMappingFunction Class Reference

class MHuiMappingFunction

Mapping function interface. Timed values use this interface for mapping the return value of a timed value evaluation. Can be used to define custom interpolation functions for example timed values.

MapValue(TReal32, TInt)

TReal32	MapValue	(	TReal32	aValue,
			TInt	aMode
		)	const [pure virtual]

Perform the mapping. Defines a function y = f(x, mode).

Implement this method that calculates a output value for a timed value based on the input value and a component/mode parameter.

For example the aValue input could be an angle, and the aMode could be a X or Y component enumeration, then the MapValue could calculate return a x or y position on a curve path.

Parameters

TReal32 aValue	Unmapped value.
TInt aMode	Mapping mode used for mapping this value.

MappingFunctionChanged()

IMPORT_C TBool

MappingFunctionChanged

(

)

const [virtual]

Determines whether the mapping function has changed since the last call to MHuiMappingFunction::MappingFunctionClearChanged() .

By default, mapping functions themselves are assumed to be constant (not changing over time).

MappingFunctionClearChanged()

IMPORT_C void

MappingFunctionClearChanged

(

)

[virtual]

Clears the change flags of the mapping function. This is called by the refresh loop after a frame has been fully drawn.
