[PD] acceleration - deceleration between coordinates - how to do this?

[Thomas Jeppesen]

Hi,

The line3 object would be perfect in my situation. The only problem is 
that it doesn't work in PD Vanilla, which is what drives RjDj - only PD 
extended seems to support the line3 object.

Thanks for pointing out the line3 object out to me though!

Cheers,
Thomas :)
