سؤال
What I initially wanted to do is this:
if (myTargetName == 'a') {
var myOtherTargetName:String = "b";
var myOtherTarget:DisplayObject = getChildByName(myOtherTargetName);
}
if (myTargetName == 'c') {
var myOtherTargetName:String = "d";
var myOtherTarget:DisplayObject = getChildByName(myOtherTargetName);
}
as you can see, I get a 'Duplicate variable definition' error since im declaring the variables twice. My solution I thought would be to just declare those variables outside the if statements, and change the variable inside the statement, like so:
var myOtherTargetName:String = ""
var myOtherTarget:DisplayObject = None;
if (myTargetName == 'a') {
myOtherTargetName = "b";
myOtherTarget = getChildByName(myOtherTargetName);
}
if (myTargetName == 'c') {
myOtherTargetName = "d";
myOtherTarget = getChildByName(myOtherTargetName);
}
This gives an error saying "access of undefined property None". Now, I don't want to set
myOtherTarget:DisplayObject
to an actual existing display object which is on the stage just yet, I want to set it to an object on the stage inside the if statements. Is there a way to set
myOtherTarget:DisplayObject
to nothing?
