I'm almost finished with a quiz of mine. I've encountered an error which I have finally pinpointed. But first I'll tell you some background info on the code.
Background
On stage, there exist 4 button components registered as movie clips. These are later stored in an array. When a certain icon is clicked on stage, these buttons are to be activated by adding event listeners to all of them. When a button is pressed, it checks if it's the 'correct' answer and removes the event listeners.
Now I have done extensive checks and narrowed down the problem to the following.
Code
This function will add button listeners to each button recursively. Note that the variable 'num' is a fixed integer between 1 - 4 which is generated earlier into the code and used for many 'if' cases.
function addButtonListener(num:int):void
{
for (var obj:Object in _buttons)
{
_buttons[obj].addEventListener(MouseEvent.CLICK, checkans(num));
}
}
This function is basically the opposite and also disables the buttons
function removeButtonListener(num:int):void
{
for (var obj:Object in _buttons)
{
_buttons[obj].removeEventListener(MouseEvent.CLICK, checkans(num));
_buttons[obj].enabled = false;
}
}
Now one thing I noticed through the use of trace functions is that the code correctly adds the button listeners but it does not remove them.
This function calls for each button to be removed.
function checkans(num:int):Function
{
return function(e:MouseEvent):void
{
if (e.currentTarget.label == xmlNodes)
{
points = points + (2 * num);
scoreBox.text = points.toString();
}
else
{
trace("Incorrect!");
}
if(myText.parent){
myText.parent.removeChild(myText)
}
closeShowQuestion(num);//closes a previous function
removeButtonListener(num);//Should I pass this variable into the end function?
GoFishing.addEventListener(MouseEvent.CLICK, fish);//Starts the process again.
}
}
So am I removing the event listeners incorrectly?
Do you need to see more code to be sure?
Thanks in advance!
