VRope with variable length

[UnsafePointer]

Hi,

I have been using Verlet Rope class, It's fantastic! I'm working in a game with variable length ropes, wich I achieve by changing the max length of the joint by calling:

((b2RopeJoint *)_joint)->SetMaxLength(((b2RopeJoint *)_joint)->GetMaxLength() + 10/PTM_RATIO);

Everything works great with the joints, I checked with the debugger, but I cannot get the VRope class update the number of sprites it uses to represent the rope, for example, when I decrease the joint a lot, I get a little sag.

Could you help me? Let me know I you need more info, like project or screenshots.

Thanks in advance,
