i just want a bunch of grouped empties and empties to simulate this piston rig that is connected by hard(?) bones and move like this
this is basically the movements i want by moving the orange piston, pulling the dark blue conector and making the purple part rotate around the end point, pushing the light blue piece to rotate the green piece together with the orange piston.
ive tried using constraints but they dont seem to be able to affect objects two constraints down the line, and all the tutorials i found are about unrelated rigging stuff.
any input as to what to try and use would be great
