I've tried my hardest to achieve a particular constraint with various configurations of the standard joints and springs, but it's proving rather difficult. So, any help is appreciated, the constraints are as follows:
Currently I have two bodies--collision does not occur between the two. Assume that body A is static. Body B needs to be able to rotate around body A at varying lengths.
However, there are a few catches:
Object B must always try to point towards object A.
It must be possible to supply a set distance from body A to body B (Presumably through setting the max/min of a slider joint).
And it must be possible to supply a target angle for the direction from body A to body B.
If further clarifaction is in order, simply ask.
