# Pause envelope generator

• I still have to check out duration. saw the video yesterday and yes, it looks quite exciting.

Anyway, for certain purposes just a pause input in the envelope generator would do the job, while rising counters, movie players or even duration seem to be a lot of paraphernalia to simple pause the envelope.
I will try out duration today. thanks for discussing!!

• You can just gate the output and keep the last value, put that as an input when you start it again right?

• Fred, I had the same idea, but trying to build it got rather complicated. And when resuming the timing starts from the beginning. Like you run from 0-100 in 10sec, but resuming from 66-100 again 10sec instead of 3sec. So you need another counter/envelope to take care on that? While all you need is in Duration right there. 6511dc-stop-envelope.izz

• Would not the relatively new Ease In-Out 2D Actor do the trick? It has the ability to Pause and Resume the action and can be done with a linear curve to match an envelope generator. Just set the curvature to 1.

Cheers,
Cam.

You are right, missed that one.

• @vanakaru

you patch works beautifully, and yes, it is very complicated. I will study it in order to understand it, but I am pretty sure it gets even more complicated as soon as I want to use an envelope with 2 or more segments.

the pause input in Ease in-out 2D is exactly what I wish I have in envelope!! it is again not easy to work with this actor if have more than one segment.

• @camilozk
you can tether multiple Ease in-out 2D actors (using the 'complete' trigger to start the next one) as if each one were a segment.

• @primaldivine

true. it is possible to draw a very complex envelope with multiple Ease in-out 2D actors, but then it gets again really complicated to pause the whole chain of Ease in-out 2D actors

• Hello,

I just discover the post and I also search a way to have an envelope working like the command on a lightning desk:
– possibility to start/pause resume
– possibility to accelerate/decelerate/go backward
Each time I give a class about Isadora, that is one of the first question when we make the first video player with automated fade, how to stop it? to go backward?
I tried to do that with user actor using envelope, with duration, it can works, but not easy to use for begginers.
It could be a great value to have that, easy to use in the tools, hello Mark and brave developers!

• @vanakaru

this one will deal with the timing and resets itself after one pass

• Pretty clever

• I make another proposition, with start/stop/resume/accel/decel/invert, it's a prototype, but show what I would find in a super envelope actor…

It's necessary to use the movie included (100 second 1 pixel movie).

• @m_theater hurra - this is genious - thanks for this idea - isadora life is going on

• @wolle-west

There's also Ease In-Out 2D which is like an envelope Generator.

Pros:

• Built-in curvature
• Pause, Resume, and Trigger inputs
• Can change two values at once (it says X and Y but you can use them for whatever)

Cons:

• Unlike an Envelope Generator, it can only have one "segment"

• @woland - thanks a lot - this possibility is great too - however in my case i create a scene, where a satellite is circling round the moon  - so I need four segments to let the object fly in a circle - I looped the envelopes by retriggering themselves - but then how can I stop the loop :-) - captured in the endless universe !

• @wolle-west

you can put a gate actor in-between and trigger it to off.

Best Michel

• @michel - sorry for my delayed answer - the gate actor is perfect for stopping the whole process - but the envelope actor doesn't stop - so i found a solution with the pulse generator - i cannot stop and go whereever i want, but at least I can do that "behind the curtain" ;-) -
