Is it possible? Chase problem

[cnbales]

I'm trying to figure out a way to start a chase then have the chase reverse and then reverse again.  So, let's say that I have a house line with 200 nodes.  The chase begins and moves forward 150 nodes then drops back to the 100th node and then moves forward to the 200th node.

Anyone have any suggestions?

There's probably a 1000 different effect looks that could be called a chase so I guess it depends on what effect you are using to create what you call a chase to know how to respond.  To me chase just means a repeating pattern that moves and we have tons of effects that can do that.

Gil, if I could guess, he's probably referring to a chase like a morph going from left to right, up to down, etc.  I think the biggest question posted was how to stop at point "X", go back to point "X", then restart and repeat if necessary.

I would be interested in knowing how to do that as well.

You can place morphs to stop exactly where you want.  The Effect Assist should make that quite easy.  You're not going to get this done with a single effect.  You will need to chain multiple effects together.

Yep, as soon as I hit sent I realized how to do it.  Senior moment...

Phrog - you had a post earlier with some screen shots on how to implement a hold.  Can you share a sequence of screen shots on how to stop at point y go back to point x and then go to point z?

If you used the morph effect, there are start and stop point sliders/fields.  You'd have to start the 1st effect at point x and end at point y.  The second effect would start at point y and end at x.  Finally the third morph effect would start at x and stop at z.  Like Gil had mentioned before, there is no one effect that will do this so your best bet is to use multiple instances to get the desired end result.  The start and stop points are 0 - 100.  If you wanted to stop on node 150 per your example, you would want to place the slider at 75.

What if you dropped down to the node level and dropped a short on effect, copied that over to the rest of the nodes (up to point y), then selected all those nodes and alt dragged to create the chase?  I was able to get that to work for the nodes I could get up on the screen as a test.  Once I scrolled the screen to select more nodes, then dragged the effects out, I was getting some really weird results with the nodes I couldn't see on the screen.  Gil or Dan might have to weigh in on this option about what is going on.

That was deblanche, not me. I tried earlier to make this chase with morphs and the challenge is "holding" the pixels that were already chased. Persistent didn't work on morphs like it did on curtain.

This will definitely be a challenge. I want to find a way myself. If I can make it work I will most definitely post the results.

I really can't tell what you guys want it to do.  If a chase turns around and goes the other way wouldn't it be running right over top of itself?  You can always draw something out in the Pictures effect and make it move and stop and whatever you want.

I'm not a 100% what cnbales is looking for, but what I'm looking forward wouldn't mean going in reverse, it would instantaneously go from one point to another.

I saw Matt Johnson do it. When I get a chance I will send the link to his video with the time so you can look.

I'm wondering if they're not looking for a single pixel (or small group) to chase to a point, bounce back a little ways, then reverse direction again and continue to the end of the run of pixels.  I've seen test patterns that will chase just a single pixel in videos.

Like this is a way to make a morph zig zag across a line.  You could layer a bunch of them if you wanted several to follow each other.  I gotta see what you want to create it.

Nevermind.  For some reason I couldn't click it when I opened the page.  After I commented and it posted my comment then it became clickable so I deleted my comment.
