| Easy way to set Javascript variables |
| What to do: load the file, open the control panel, press the play button on the animation timeline (watch at least 5 seconds of simulation). |
This demonstrates an easy way to fetch variables from the system, even knowing
few things about the model interface (the way javascript can access
the objects of chrono systems).
In fact, look the two probe objects which monitor the
reaction forces in the springs: these probes are in 'Set JS variable' mode,
hence setting our two custom variables 'force_a' and 'force_b'. Then,
the two links 'needle motor' simply use this variable to impose the
rotation of the two needles (look the property window of the motors,
in the Custom tab).
