SignalGenerator(<-interval <-sigFrequency <-phaseShift false <-signalType) ->sigValue

Computes the value for a given signal waveform and pushes it to the stack.

A function to derive the y-coordinate for a given x-co-ordiante on a graph line following one of the indicated wave patterns. Uselful to animate an object or to a given pattern over time. Could be used for instance to vary output from an emitter. Oscillating rightness of light source or beacon; Oscillating strength of an emitter over time - both of these can be thought of as a a use case for this function.

Arguments and type in order: 1: Integer. the X coordinate in the waveform (Eg. time) \
2: Float. Frequency of the waveform \
3: Float. PhaseShift of the waveform \
4: Bool. invert the waveform \  5: Integer. Signal type (0 to 6 in types, below) \

Signal types. 0 = NONE <br/> 1 = SINE <br/> 2 = SQUARE <br/> 3 = TRIANGLE <br/> 4 = SAWTOOTH <br/> 5 = RANDOM <br/> 6 = CONSTANT <br/>
