Vehicles and scripting

In my interest to learn how vehicles are made, I unlinked one to look at the parts, then relinked them. After which, it no longer worked!! (was a copy). I know link order is important in some objects, but what order for vehicles? Which also brings up another issue. How do you select, say, the hidden parts under the body (the chasy)?? I can select all with a drag selection, but that does not select in a special order!

Are there any documents which you can direct me to which will answer my questions?

Thank you

There should be one prim that has all the vehicle scripts. It will be whichever one was the root prim of the object when it was first linked. Just look through them and you should find it, then just link that prim last.

It really depends on the scripting inside the vehicle on whether the link order is important. Look for llMessageLinked functions inside the script found in the root prim. That would tell you if there are any specific linked prims. I've looked at several free vehicles and they usually are not that complicated. What Joeski said, make sure the root prim is the last object linked.

To make a prim the root prim when doing a drag select: Drag select all then de-select the prim you want as root and then select again and link. If that doesn't work well for you then drag select all, de-select the prim you want as root, link the rest then select the linked object and select the root prim and link.

Whew, hope that makes sense.

Thanks all for the help. Yes, it makes since.

So the scripts do not need to be in any one specific prim (such as wheel or driver seat)? Does all that maters is that the scripts are in the 'root' prim no mater WHAT it is?

Thank you again.
