Hi everyone,

I'm building a live race timing leaderboard in XPression that stays permanently on air and updates in real time from an external TCP data feed. I have two questions I couldn't find clear answers to:

**1. Triggering animations on a permanently live scene**

Normally XPression plays a scene linearly from in to out. But my leaderboard scene needs to stay on air indefinitely and react to incoming data signals (via RossTalk GPI). What's the recommended approach for triggering animations mid-playback on a scene that never goes off air?

**2. Animated position swaps (smooth Y-axis transitions)**

When two competitors swap positions in the standings say rank 4 and rank 5 exchange I want the rows to smoothly animate to their new Y positions rather than instantly jumping. Each row needs to know its target Y position and tween to it.

Is the right approach here to drive Y position via a parameter with an eased transition, or is there a better pattern in XPression for this kind of data-driven positional animation?

Any pointers to examples or documentation would be greatly appreciated. Thanks!

1. I normally use something like onSetText linked to data to trigger a scene director or a GPI that triggers a scene director.
2. Can only be done with scripting keyframes.

Both these requests require scripting, would you like some samples?

Hi.
Attached is a sample project, just as you want.
