Thats more of an animation task that you want there. Try making a method that moves the kids subparts in his legs with the pedals in a Do Together. Just try trial and error: put code in, play the world, see what is wrong, fix the numbers in the code to make it work better and go on to the next step.


Check out my best projects so far and please comment:

Question 05-04-2010, 10:38 AM

I'm trying to do this too, I tried following the above comment, after an hour, no success =(. If someone could link to a tutorial of something, that would be great.

There really is no tutorial its all really just trial and error and know how. Like the guy two posts above me said, just put in a do together statements, have the subparts move together so it looks real and just mess around with the values. If you post the world i could possibly help you with it.

Unhappy Not a Good Design - 05-06-2010, 12:05 AM

Many objects created for the Alice Gallery were not designed for functionality as much as for show. If you look closely, you will see that the upper legs are not uniformly placed on the hips of the rider, but were positioned to fit the pedals where they are. Rotating the pedales just a 1/4 turn results in the left leg not being able to reach the left pedal even at full extension. A half rotation makes the problem worse. To fix it, you will have to move the upper legs in addition to turning them. It looks really awkward.

Another example of form over function is the Roller Coaster ride. There is no easy way to actually make it run.
