Perfect Sitter & Staying Level on a Bike

In trying to construct a new low-prim motorocycle, we're using Piero Padar's Perfect Sitter to allow clients to be able to adjust their position on the bike relative to the seat, handlebars and footrests. All the Perfect Sitter scripts along with the driving scripts for the bike are in a "script box" prim on the bike. The location <x,y,z> of this box seems to be crucial as the bike tends to try to "right itself" once you sit on it and thus raises the back end higher than the front end. Also, if you tend to "adjust yourself" too far forward you can also cause the bike to tilt forward before you begin your journey.

Would someone explain the significance of what's going on? Is it weight distributions? Should I change the size, shape,and location of the script box? At this point I'm about to go crazy trying to figure out the "pattern" that's causing this. HELP!!!

Thank you,

Hmm... I will following this thread with interest, as I was considering using the Perfect Sitter to do exactly this, and I hadn't realised there was likely to be a problem.

The way the script must work, as far as I can figure it out, is to use llSetLinkPrimitiveParams() to move the seated av relative to the root prim. Is your bike's stability similarly affected if you move other child prims about?

The answer to your question is a definitive, "I think so!" We've been trying to nail down a pattern but, with the recent "issues" SL has been having these last few nights it's been difficult to discern what is a true problem and what is just a side effect of an ill-feeling grid. In working with other areas of the bike, however, I'm going to stick with my answer for, even whether the prims are "made of" wood versus steel seems to have an impact on the bike's physics.

An additional bit of peculiar behavior I'm noticing is when one of my partners finishes with the building of the bike and passes it to me to add the multi-sit scripts. When I rez the bike, the bike actually is rezzing higher off the ground than it did when he initially built it. I have NO explanation as to why this may be happening.

Thanks for your interest in my dilemma.

contact me inwold bro, I solved this after may hours of tests & trials
