The hook itself was a separate object that I animated to whirl around the girder; I used MD to animate the cable, whose fixed end was parented to the hook.
For the cable, I used MD_MetaPlug – calculating MD on a “ribbon” substitute and then playing back that calculation on the cable itself. As mentioned above, the fixed end was parented to the same null as the hook.
To keep the other end taut, I made the other end a fixed surface as well and used a null as a reference object for that end. I animated the reference object to move the other end of the cable up and down. Up for more slack, down to make that end of the cable go taut.
After the MD-controlled cable looked correct, I tweaked the rotation of the hook and its null-parent to make it latch onto the cable. If I moved the null-parent to do this, I recalculated the MD on the cable. I kept doing this a few times until it looked right.
In retrospect, if I knew enough about which part of the cable would get latched by the hook, I could have made that part of the cable a fixed surface that was also controlled by a reference object. That would have taken some of the guesswork out of where to latch the hook. Still, by using a ribbon instead of the full cable, MD calculations were done in a flash.
loves MD_MetaPlug!!! :love:
