How Do I Maka An Object Walk?

I'm wondering how you can get an object to move, to that of mimicking walking in reality. If anyone can provide to me the full set of commands or a tutorial...

Some of the objects in the gallery, such as a penguin, and possibly a cow, already know how to walk. If you can use one of them, you can save yourself a major programming headache.

If you aren't in too big a hurry, Alice 2.2, which is supposed to be released fairly soon (famous last words) is supposed to provide walk methods for some of the people objects as well.

Also if you use "hebuilder" or "shebuilder" - both in the People library - to make your human character, it will have a built in walk method. That method, which uses poses, is also a good one to start with for your own methods.

If you're on a PC, the characters in "Storytelling Alice" also have some interesting walk methods.

Hello,

I have had mixed results with the shebuilder model. When I try to make her walk, her leg parts seem to detach from each other as she walks. I teach 9th grade and just recently ran into this problem. I have attached a test world wondering if perhaps the student edited the shebuilder walk method. Apparently, I am getting the same results. Any clues? Is this a bug within Alice?

We have version 2.0.7 .

The problem with the shebuilder example is that the figure has been resized (see screenshot comparison to a new figure). This changes the relative positions of the various body parts (there should have been a warning message about this) and the poses used in the walk routine are no longer correct. If you duplicate the original poses for the resized figure, a bit of work, admittedly, the walk routines should work fine.

But the effect was pretty cool. It would fit well in those dancing contest videos that we have been seeing lately.

There are some good examples of how to create human motion in the War Zone video at http://www.alice.org/community/showthread.php?t=1285

There is one method that implements running and another that implements climbing. The climbing motion is extremely realistic. Congrats to Chris101b.

Thanks. This is my fault. I have the kids resize objects so that I can see them easier and didn't think much about how my action effected their world. Ha!! Thanks. I would have never figured this out.

I did get quite a laugh from the students though when they tested their animations. Of course, there is more than 1 student that has this problem.

Resizing like this can be a very good way to get interesting animations - as long as you are expecting it.
