Reset a numeric variable in As3

Question

I have a script for a counter that I increment from a button,

the script is:

var MyCounter:Number = 0;

Inside a button script:

.....bla bla ...

MyCounter = MyCounter + 1;

MyText.text = MyCounter.toString();

When I restart MyCounter from 0

I try:

var MyCounter:Number = 0;

if MyCounter was 4 it follow with 5 and so on.

Which is the syntax to reset the var in as3?

Thanks.

To reset the value to zero you would just need to assign it a value of zero.  MyCounter = 0;What you just wrote makes it look like you declared the same variable again instead.

The compiler is telling you the variable already exists so you shouldn't use 'var' or a type (Number) again to try to create it, you should just assign a value.

If you're using timeline scripts and you're doing something like hitting frame 1 and are getting errors there because you decalred them, you'll have to sniff for existence.

e.g.

if (MyCounter) { MyCounter = 0; } // exists already, just reset
else { var MyCounter:Number = 0; } // doesn't exist, create

Happens a lot when people return to instantiation frames. If you have a lot of variables you instantiate on that frame (if that's even the case) it's better just not to return back to that frame. Make a function to clear your variables and don't go back to that frame.

function Reset():void
{
MyCounter = 0;
// reset other stuff
}
