Willi Posted October 24, 2005 Share Posted October 24, 2005 hi all, i want to know if it´s possible to do something like this with a:m and only expressions on bones and nulls: http://www.sukio.de/gallery/AutoBug.htm hope any of you have maybe ideas.

Steven Cleary Posted October 24, 2005 Share Posted October 24, 2005 I think it is possible and I'll be having a bash at it soonish. I'd want to specify things like step height and step length via a pose slider or even make them dependant on the speed of travel. Hmm, many things to mull over... Steve.

Willi Posted October 24, 2005 Author Share Posted October 24, 2005 if one leg can do this, http://www.sukio.de/gallery/GroupieConstraint.htm then it´s not so far away from finishing... Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted October 24, 2005 Hash Fellow Share Posted October 24, 2005 Something like this: -place a null where a foot has been planted -measure the distance a footplant has moved relative to the body as the body leaves it behind -test if it has reached a certain limit -at, say 90% of that limit, start moving the foot forward to it's original position relative to the body -at 100% finish moving the foot forward -reset the null to the new footplant location -back to step 2 Quote Link to comment Share on other sites More sharing options...
Willi Posted October 24, 2005 Author Share Posted October 24, 2005 please, could you make a project file? how can it look in a:m "code"? Quote Link to comment Share on other sites More sharing options...
strohbehn Posted October 24, 2005 Share Posted October 24, 2005 Willi, Take a look at the exerpt below from this thread: http://www.hash.com/forums/index.php?showtopic=9975&hl= It doesn't use expressions, but may be of some help. Look at the project file and read the tips below. "I've been playing with TempleTiger's file and came up with this. It's not meant to look like a normal walk cycle yet. It just demonstrates several great features. Here are a few things to note: http://www.mstrohbehn.lunarpages.com/AM_Pr...wingSurface.prj 1. No matter where the body is moved, the leg fall will hit the surface correctly and not go below the surface level. 2. The leg "walk cycle" can be controlled via a foot control constrained to a path and the "ease" value on a path constraint (in this case the foot path spline is controlled by the "FootPathRotator" bone). 3. In addition, the "FootPathRotator" bone (and therefore, the path) can be rotated to allow the critter to "walk" in any direction. 4. For variety in the leg's movement, the foot path spline could be animated via muscle keyframes to allow, for example, a higher leg lift or a longer stride at cerain times. Scrub it slowly forward and backward in shaded, wireframe mode while looking at the "ease curves" of the Null's "constrain to path" constraint to see what I mean about point #3 (above)."
