hi,

I'm new to houdini, and I have a few basic questions:
so, I would like to generate a number of particles on the letters of a word, and then have them move to a new position on a second word with the same number of letters.

my question:
- what's the best way to achieve this? it feels like I would somehow have to create a vertex attribute with the index of the letter the particle is on, and use that to find the destination coordinate on the second word. then I'd be able to interpolate between start and end position based on the current frame. — I'm just not sure how exactly to do that.

bonus question:
- is there a way to store the text string and the number of scatter points in a single place / variable so that I don't have to change it in multiple places?

thanks a lot in advance!

This is typically done with goal points. Create two sets of scatter points, one in the source geo and one in the target geo. The scatters should have the same count. Then assign the target points as a goal point attribute on the initial source points. Inside the popnet1 drop down a PopSeek and assign the goal point as the point the source point should seek. Play around with the braking options to adjust the overshoot.

awesome! thank you, @Enivob
