Pause envelope generator

jhoepffner

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!

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).

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.

@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" ;-) -

if anybody is interested how to control a satellite in universe

@wolle-west

my proposal for your problem:

EDIT: a better version than the first I posted (pause/resume works better)

@jfg - this is perfect - thanks a lot - the communication in this community is wonderful - what a luck to be part of it - i will study your proposal for being prepared for my next fly to universe

It'd be great if you could share these example files on the Add-Ons page so that they can be found more easily by others in future <3

Best wishes,

@woland thanks for the tip - i did it
