Simple clutch in SketchyPhysics?
-
Is it possible to make a simple clutch in SP, by for example changing the "damp" parameter of a hinge joint dynamically while a simulation is running using a ruby script?

The static parameters are a little iffy as you would need to rewrite some basic SP functions, so I made a more roundabout example where the script simply adjusts the controller input, the clutch wont free run but the gradual power is pretty accurate.

Thanks Mr K! Your clutch works pretty well, but unfortunately I need a clutch that can free wheel. However I learnt some new stuff about using ruby scripts so thanks again! I am working on a magnetic clutch which is almost doing what I want it to. I will probably incorporate some of your script. I had read some stuff about how difficult it is to access the static parameters when the simulation was running, but I though I would ask, just in case that issue had been resolved in SP 3.2.
Cheers!

Just in case anyone is interested, I have attached a model using my magnetic clutch idea I mentioned earlier, combined with the helpful ruby control codes from Mr K, which allows the driven part to free-wheel when the clutch is disengaged. By changing the status of the yellow driven part in the model to "static", the clutch becomes a dynamic brake powerful enough to stop the motor. Might be an idea to have a clutch/brake joint in SP 4.0?
