Syd,
I did some experimenting with the new properties. Here are my results that I
have for the SenecaII:
A nasal mouse motion handler:
var MouseHandler = {
new : func() {
var obj = { parents : [ MouseHandler ] };
obj.property = nil;
obj.factor = 1.0;
obj.YListenerId = setlistener( "devices/status/mice/mouse/accel-y",
func(n) { obj.YListener(n); }, 1, 0 );
return obj;
},
YListener : func(n) {
me.property == nil and return;
me.factor == 0 and return;
n == nil and return;
var v = n.getValue();
v == nil and return;
fgcommand("property-adjust", props.Node.new({
"offset" : v,
"factor" : me.factor,
"property" : me.property
}));
},
set : func( property = nil, factor = 1.0 ) {
me.property = property;
me.factor = factor;
},
};
var mouseHandler = MouseHandler.new();
And the corresponding pick animation in the model gets the action
<action>
<button>0</button>
<repeatable>false</repeatable>
<binding>
<command>nasal</command>
<script>SenecaII.mouseHandler.set(
"/controls/engines/engine[1]/propeller-pitch", 0.01 );</script>
</binding>
<mod-up>
<binding>
<command>nasal</command>
<script>SenecaII.mouseHandler.set()</script>
</binding>
</mod-up>
</action>
This sets a mouse-motion handler when the button is clicked on the control and
removes the mouse-motion handler. The hander executes the property-adjust
command for the given property.
There is no support for the x-axis yet, but probably easy to add. Maybe
something like
mouseHandler.setXHandler( prop, factor );
mouseHandler.setYHandler( prop, factor );
Once this idea has matured a bit, it probably should go into the global Nasal
directory (controls.nas?)
What do you think?

Gaining the trust of online customers is vital for the success of any company
that requires sensitive data to be transmitted over the Web. Learn how to
best implement a security strategy that keeps consumers' information secure
and instills the confidence they need to proceed with transactions.
