LinearEnvelope

LinearEnvelope

An Envelope used for interpolation between 2 values linearly.

LineEnvelope requires 2 Envelope values.
The value will be interpolated over the length of the loop provided. See Loops.

For example, the following will animate the X position of the particle relative to its originLocation, from 0 to 5, over 21 ticks. It will then repeat forever:

positionX = LinearEnvelope(0.envelope, 5.envelope, RepeatLoop(21))

(0.25, 0.5, 0.75, 1.0, ...)
Note that in this case we made it last 21 ticks instead of 20, for the jumps to be in 0.25's.

You can pass any type of envelope, for example:

positionX = LinearEnvelope( 
    LinearEnvelope(0, 5, RepeatLoop(101)),
    2.envelope,
   BounceLoop(20)
 )

All envelopes have secondary constructor with the NONE property type as the default, which is used for the nested envelope above.

You can get real creative with this! You can pass Envelopes as both parameters, and even create Envelopes nested inside of Envelopes nested inside of Envelopes nested inside of (you get the point)
