The following example uses an
if
statement to evaluate how long it takes a user to click the
submit_btn
instance in a SWF file. If a user clicks the button more than 10 seconds after the
SWF file plays, the condition evaluates to
true
and the message inside the curly braces (
{}
)
appears in a text field that's created at runtime (using
createTextField()
). If the user clicks
the button less than 10 seconds after the SWF file plays, the condition evaluates to
false
and
a different message appears.
this.createTextField("message_txt", this.getNextHighestDepth, 0, 0, 100,
22);
message_txt.autoSize = true;
var startTime:Number = getTimer();
this.submit_btn.onRelease = function() {
var difference:Number = (getTimer() - startTime) / 1000;
if (difference > 10) {
this._parent.message_txt.text = "Not very speedy, you took "+dif"
seconds.";
}
else {
this._parent.message_txt.text = "Very good, you hit the button in
"+dif" seconds.";
}
};
