in an action, move from existing poistion?

[hayasidist]

I feel I should know how to do this, but I can't seem to make it happen…

I have a regular action. It rotates a bone.
I want the action to _add_ (say) 30 degrees to a bone's rotation. (i.e. if the bone starts at 0, the first time the action is invoked the bone is moved to 30; second time to 60 etc etc) similar to additive cycles.

But I don't want all bones to be treated this way.

Have your bone with an additive cycle and have that controlled by a separate smart bone?

You'd just need to rotate the SB to increment the angle.

thanks for the idea -- it prompted me to rethink my approach -- I've "inverted" the problem -- rather than a regular action I now have an SB action

Originally I wanted a regular action to insert in the timeline that did some standard stuff but needed to "keep count" of how many times it had run.

I now have an SB action that has a cycle to "do the stuff"; and it knows how many times it has run by how far round its dial it's gone!

no need for additive cycles or scripting (which was where I nearly was!)
Thanks again
