Sets the input signal of this mechanism.
The function issues two callbacks to the object:
a) OnInputSignalChanged(operator, sender, value) => gets called only if the value changes
b) OnInputSignalSet(operator, sender, value) => gets called every time the signal is set
This function should handle everything that happens when the input
signal is set (on the generic level).
For the object-specific functionality this function issues a callback to the object:
* OnSetInputSignal(operator, sender, value)
Use these callbacks to activate or deactivate certain functions in the mechanism.
Use the callback to activate or deactivate certain functions in the mechanism.
For example, the stone door opens if you pass 'true', and closes if you pass 'false'
Usually only the signal changed callback should be relevant, but who knows. Callback b)
can be removed at any time if it turns out to be unnecessary.
That callback happens after the generic handling is done, so that the object
can safely be deleted in the callback.
@par operator this object is operating the mechanism or the object that sent the signal-
@par sender this object sent the signal - this is usually a switch.
@par value this value is sent.
