Creating a function within a loop (pointers?)
- by user352151
Im trying to create a simple loop that creates 50 buttons, adds them to screen and then when a button is pressed, it traces out that number. I can get it to work by doing stuff I consider hacky (such as using the buttons X/Y location to determine its value), but I'd rather just be able to hold a single value in the function.
The code itself is:
for (var a:int = 0; a < 5; a++) {
for (var b:int = 0; b < 10; b++) {
var n = (a * 10) + b + 1;
var btt:SimpleButton = new BasicGameButton();
btt.x = 20 + b * 50;
btt.y = 50 + a * 80;
addChild(btt);
btt.addEventListener(MouseEvent.CLICK, function f() { trace(n); } );
}
}
At the moment, whenever a button is pressed, it simply outputs "50". Is there a way of "freezing" the value of n when the function is created, for that function? (BasicGameButton is just a square button, created in the flash library)
Many thanks.
