Align To, Link and Mask

In my testing a mask can be Align TO and Linked to text so the the mask grows as more text is added. What I would like to do is also move the mask so that it reveals or hides the text. So far I haven't been able to do move the mask independently of the text or a rectangle behind the text. I assume that there is no way using Align To and Link to also move the mask as I would like to.

seems you need to build a link library

Not sure, what you try to accomplish:
for sure, you can resize the Mask according to the Titles size: Link the masks Width with the titles Width.

And for sure, you can move the mask (e.g. to unveil the text) by ramping its X-position. (or ramping its width by adjusting the Scale in the Link behaviour.

What NOT works is, to add a AlignTo AND 'override' that alignment (e.g. by using a Custom behaviour) … aligned to left border means aligned to left border....


So, post some screenshots, what's your plan ....

oh, and one more thing: don't forget, Masks do have Anchor Points too!
setting the AP on the far right of the mask and changing its Width makes it grow just to the left …

Attached is the title that I am working with from inspiration from Simon Ubsell, the Ripple guys and you. I am now using a guide so I know where to have line breaks in the text. But instead I want to have the mask to grow with the length of the text. I haven't had much time to work on this but will try to figure it out this week sometime between taping sessions.

sorry, Bob,, dl your Project - still don't get it:
why Align-To, why 'adopting' the width of the text?
Look:
this is your preset:



Mask has the same width of the text area.
but…



… when you use a Mask size of the full-screen, it uncovers the same! The left border of the Mask - that is where the action starts , independently of size of Mask.
And when the text gets wider/longer, the uncovering starts on the left anyhow …

I don't see the need of AlignTo and adopting Width… :huh: ?

Yes you are right about the mask. That title is not a good representation of what I was wanting to do. Probably if I wanted more text to show I could rig the mask to move more to the right on X. Thank you for your help,

sorry for being stubborn, but …

hmm? when the Mask covers the full screen, and moves completely to the right - the Width of the text doesn't matter :S
A smaller text gets as uncovered as an all-across-the-screen one .....

Still don't see a need of a 'flexible' mask (for your task, and as I understand it) - a mask covers only content of that Layer it is applied to.

No?
(just tryin' to help…)

Sorry I haven't been back to this posting. I had to finish 26 videos.

Now I am back to this process and have dropped the idea of a variable size mask. When I was using this title on the latest projects I had to manually move the line down according to how many lines of text there was as a Title. Then I would use the Last Point Offset to change the length of the line. With the new version of this title I have made a Pop Up rig to select where the top of the line is positioned according to how many lines there are to the title. The problem I have run into is that only one of the Last Point Offset will work on the Pop Up. It does not work on the other Pop Up selections. I tried linking the Last Point Offset but there was not any Compatible Parameters that would work . So I am at that point of knowing what to do to make the Last Point Offset work with each section in the rig.


Sorry for the double posting.

I solved the problem.

in terms of community, would be nice if you share how …


And, I don't get your original post together with your last pic … :blink:

Do you want to reveal the text block, line by line? And the triangle 'hops' karaoke like? And the orange line corresponds to the lines of text? …

I gave up trying to make a mask grow or shrink according to how much text is used. Instead I decided to make the vertical line line up to the 1st line of text after the title of the subject. Using opacity and a pop up widget I was able to have the top of the line even with 1 to 4 lines of text. When I started using the original title I created on a bunch of videos I spent a lot of time adjusting the top of the line. So now in the second version of the title I will only have to adjust the bottom of the line using the last offset. Here is a copy of the title for anyone to download and modify.
