Hi, Suna,

There are various ways of making an object behave in a manner that could be described as "following a path."

(1) Here's a very simple way, which *might* suit your needs:

Bring up the halo on your object, and look in the "extras" submenu of the halo menu; you'll see three "path-related" items. When you choose "define path", the cursor changes to a special "path-defining" cursor, and you're invited to drag your object in the path you wish it to follow; release the mouse button when you're through.

You can then get the object to re-traverse that path any time by choosing "follow existing path" from that same menu. Or, to follow the path programmatically, deploy the "follow path" tile, which you'll find in the "miscellaneous" category of a Viewer.

(2) If the path can be defined by a series of points in the x-y plane, another approach is to write a series of ticking scripts, each of which is in charge of getting the object from one of the reference points to the next; each such script, once it has accomplished its purpose, "stops" itself and starts the next script in the sequence to ticking.

Incidentally, the ideal place to post this kind of question is the Squeakland mailing list. If you're not yet a subscriber, I encourage you to join :-)

If neither of the above suggestions fulfills your needs, please describe what you want in more detail, and most likely you'll receive more suggestions from readers of the Squeakland list.

Cheers,

To whom it may concern,

I'm a student at UIUC, and I'm really wondering about how I can make an object to follow a path. For example, I'd like to have 'a planet' follow a specific orbital.

I tried ' the method of making smart car', which use test script but it is not enough to meet my need.

Thanks a lot, Suna
