As promised, a full response to the thread, including what I hope is a clear step-by-step guide:
did you review my block?
I have done now, thankyou. I'd read somewhere that action grips and constraints don't play well together, although that doesn't seem to be the case in this instance. I think for simplicity's sake a move action's the way to go now, but it's certainly something I'll try to remember for more complicated geometry.
I agree, there's many ways to skin your prey. However, there's also rarely anything more frustrating than doing the proper steps and not knowing why it doesn't work. I appreciate when I am shown where my errors lay.
Have to admit I shot off my first post without looking at the attached block and that I got to edit it to make it look like I did. Otherwise I would have addressed the grip association issue then.
I must admit I'm still not 100% what I was doing wrong but I've managed to edit Lee's block to reproduce it, and edited my block to also work properly, so I must've been missing a click somewhere.
While I was trying to search the web for how to do this, I found a lot of replies that were along the lines of "set the distance multiplier to 0.5" and just left it at that. In an effort to help the next person who has this problem, a complete step by step guide:
1) Add linear parameter;
2) Set the linear parameter to Chain Actions=Yes and adjust the number of grips as desired;
3) Add a stretch action to the linear parameter;
4) Add a move action:
4a) Select your linear parameter;
4b) Select the endpoint of the linear parameter;
4c) Select objects to move;
5) Select the move action and set the Distance Multiplier to 0.5;
6) Test the block
6a) If it doesn't work curse loudly and repeat from step 4;
6b) If it does work pat yourself on the back proudly
