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.

MappingFunctionIdentifier()

TInt

const [pure virtual]

Returns the mapping function identifier on the server side.
