The Array.splice method, in AS1 at least, is very slow. For that
reason, In situations like this where you would make repeated calls
to it to remove one item I prefer to:
- create a new Array
- iterate the original array with a for loop
- push the items I want to keep into the new array
- dispose the old one when done.

Hi everyone,
I'm having a braindead moment today, which I was hoping someone could
help me with.
I have the following array...
//Create array with 5 elements
var myArray1:Array = new Array();
myArray1.push( new Array("A:", -1) );
myArray1.push( new Array("B:", -1) );
myArray1.push( new Array("C:", 0) );
myArray1.push( new Array("D:", 0) );
myArray1.push( new Array("E:", -1) );
myArray1.push( new Array("F:", 1) );
myArray1.push( new Array("G:", 0) );
myArray1.push( new Array("H:", -1) );
//name, score
...and I'm trying to remove all the elements in myArray1 with a
score of
less than 0 without sorting/reordering the array at all.
I was trying to use a 'for loop', but obviously as the elements are
removed, the length of the array changes & causes the wrong
elements to
be deleted.
Can anyone help?
Thanks,
--
