One thing that I have found with multimedia and WWW
design is that it is important to force the user to
interact in the design, and make them think. The best
animation, and the best text in the world do not count
for much if the user becomes bored with endless animation,
and reading from the screen. A good example of user
interaction is to get the user to enter values which
are then checked, and automatically marked. For my
subnetting examples I have used the following:
The ActionScript randomly generates IP addresses,
within different classifications (Class A, B or C):
|
i=random(3);
trace(i);
if
(i==0) //Class A address with 255.255.0.0 SM
{
val=random(126)+1;
ip=val + ".x.y.z";
sm="255.255.0.0";
ans1=val + ".1.0.0";
ans2=val + ".2.0.0";
ans3=val + ".3.0.0";
}
else if (i==1) //Class A address with 255.255.255.0
SM
{
val1=random(126)+1;
ip=val1 + ".x.y.z";
sm="255.255.255.0";
ans1=val1 + ".0.1.0";
ans2=val1 + ".0.2.0";
ans3=val1 + ".0.3.0";
}
else if (i==2) // Class B
{
val1=127+random(63);
val2=random(250)+1;
ip=val1 + "." + val2 + ".y.z";
sm="255.255.255.0";
ans1=val1 + "." + val2 + ".1.0";
ans2=val1 + "." + val2 + ".2.0";
ans3=val1 + "." + val2 + ".3.0";
}
subnet1="<1st address>";
subnet2="<2nd address>";
subnet3="<3rd address>";
setProperty
("tic1", _visible, false);
setProperty ("tic2", _visible, false);
setProperty ("tic3", _visible, false);
text_ip=ip;
text_sm=sm;
|
and the script to respond to the user entry is:
|
if (subnet1==ans1)
setProperty ("tic1", _visible, true);
else
setProperty ("tic1", _visible, false);
if (subnet2==ans2)
setProperty ("tic2", _visible, true);
else
setProperty ("tic2", _visible, false);
if
(subnet3==ans3)
setProperty ("tic3", _visible, true);
else
setProperty ("tic3", _visible, false);
if
(subnet1=="?") subnet1=ans1;
if (subnet2=="?") subnet2=ans2;
if (subnet3=="?") subnet3=ans3;
if ((subnet1==ans1) && (subnet2==ans2)
&& (subnet3==ans3)) gotoAndPlay(10);
else gotoAndPlay (2);
