can you make a version of it that uses c=c+1 / c=c-1 and set_zoom(c) instead of press('zoom_in')?
Sorry, I don't understand what you're asking for.

your version of the script uses press('zoom_in') and press('zoom_out') for zooming. I'm wonder if it can be replaced by c=c+1 / c=c-1 and set_zoom(c) to have full speed zooming

You could have it repeatedly call set_zoom, but that won't give you a smooth zoom like holding the button down. It will be a bunch of jerky steps, much slower than full speed zoom.

On one of my cameras
Code: [Select]
for i=1,50 do set_zoom(i) end
took 11.3 seconds.
Code: [Select]
set_zoom(50)
took 0.9 seconds.
