Basic Boat Script

In the Basic Boat Script, which command line controls the position in which the passenger sits on the boat? The driver is controlled by SitTarget, but the is no such command for the passenger. Anyone help? Thanks..:~)

nothing in there controls the position of passangers, you may set up additional sit targets in child prims to control positioning of passengers, or you can rely on the built in sit functionality. each additional sitting avatar reduces the prim count usable for the base vehicle by one prim

Janey, chack out http://www.heatonresearch.com/articles/188/page2.html.
I found it very informative about how passengers are set up in vehicles. It then goes on to do a boat also.
Hope it helps.

Good luck

Thank you so much, Carbon...I read the info there and got it working. ) Thank you again.
