Another ticker scroll

[alonh]

I'm taking my first steps in Wire and trying to build a scrolling ticker for use in a TV studio.

I've experimented with a few approaches:

• Text Animator
• This post: viewtopic.php?p=96186&hilit=scroll#p96186
• Using OBS as an input

Each method has its own limitations, so I turned to Wire to see if I could build something more tailored.

My requirements are:

• Right-to-left text
• Left-to-right scrolling animation
• Dynamic text content

The text can be longer or shorter than the screen width, and I'm sending the content via REST API which allows me to pre-format it properly for RTL display.

The Juicebar plugin actually hits most of these requirements, but its animation only scrolls right-to-left, which doesn’t suit my use case.

In Wire, I’ve managed to clone text using a linear and animate it with a saw.
However, I haven't found a way to evenly distribute the clones regardless of text length.
I suspect the right approach is to calculate the saw amplitude based on the total text width but I’m not sure how to go about that.
Even more so, adjusting the amplitude also changes the scroll speed, so I probably need to compensate for that as well.

If anyone could help it will be you guys, thanks!

This reminds me, you can't expose the font or the style in wire either, but dosen't answer your question!

I found that adding a Delay that's connected to the Text Renderer position helps control the spacing between text instances.
However, since the number of instances can't be modified in real time, handling dynamic text remains an issue.
