Re: [www-vrml] [xVRML] new screen snapshots and the future

Hi all,

Oh my gawd!!! I can't believe I got this wrong!
I make a total retraction of what I said about eventIn and eventOut not being available inside PROTOs without a Script mediating.

A big thankyou to Brian Hay for putting me right here.

After Brian stated so certainly that it could actually be done I tried what he said. I was absolutely sure it illegal syntax. It is hard to describe how utterly astonished I was to see it work! Wonderful! I'm rapt to see I was so wrong (and a bit embarrassed too).

Here are the two examples I used to prove it to myself:

-----snip------

#VRML V2.0 utf8

PROTO timer[
   eventOut SFTime now
] {
   DEF ticker TimeSensor {
   	loop TRUE
   	time IS now
   }
}


Shape { geometry DEF readout Text { string "-" } }

DEF clock timer{}

DEF convert Script {
	eventIn SFTime time
	eventOut MFString str
	url "javascript:
		function time(now) {
			str[0]=now;
		}
	"
}

ROUTE clock.now TO convert.time
ROUTE convert.str TO readout.string

	eventIn SFBool thisSky

		skyColor [

		]
		groundAngle [ 1.07 1.45 1.52 1.57 ]
		groundColor [

		set_bind IS thisSky
	}
}
