Methods

MethodDescription

at

at(index: number): Point2DSignal

Returns an Point2DSignal for the history value at given index.

For example, SignalHistory.at(0) returns value of signal at previous frame, while SignalHistory.at(1) returns value of signal at two frames ago.

Note: See also SignalHistory.frame method which uses more intuitive negative indexing. Note: You can use SignalHistory[0] to achieve same effect as calling SignalHistory.at(0)

frame

frame(relativeFrame: number): Point2DSignal

Returns an Point2DSignal for the history value at given frame relative to current one.

For example, SignalHistory.frame(-1) returns value of signal at previous frame, while SignalHistory.frame(-2) returns value of signal at two frames ago.

Note: See also SignalHistory.at method for approach which is index based. Note: You can use SignalHistory[-1] to achieve same effect as calling SignalHistory.frame(-1)
