resetting Floor constraints...

Post by malefico » Tue Nov 22, 2005 1:30 pm

Hi, I wonder if you guys have noticed this (copied from an email I sento to Ton):

> I'm using a stride bone together with "sticky" Floor
> constraints on the character's feet (this get rid of tiny slides),
> and I must say it is a pleasure to work with it. There
> is however a little odd thing with Floor constraints:
> when the animation is played back again, the feet
> bones get stick to their last position until they're
> lift by the action. This produces of course a weird
> stretch of feet mesh. You can of course solve this, by
> manually lifting the feet's IK bones. Maybe the
> constraint should be "reset" at the end of the
> animation ?

>The problem as I see it is that both start
> and end frame, have the feet in contact with the Floor

> character was moved to the initial position.


Maybe it's just a natural limitation... could it be fixed ?

Kind regards

malefico.

I wrote the floor constraint. Can you post a small OpenGL animation that shows the weird behavior so I can better understand what you mean.

While on the subject; at the moment the root of the constrained bone obeys the floor constraint. Would it be possible to add an option to use the tip?

Harkyman, is there some sort of documentation for the floor constraint?

I see it was added after 2.37, but there isn´t a single mention of it on the 2.40 release logs.

check out this rig. I used the floor constraint in a very cool way. one thing I notice is that when you grab the floor bone and move it, it doesnt effect the constrained bones like it should. its still cool tho. oh yeah if anyone else has a good place to host that rig I will donate it when i am finished.
