Primarily, all the elements of the vector need to be of the same type. I think it will work with objects. The other difference is that you can't have empty elements in a vector. This is perfectly legal for an array: arr[0] = 0; arr[1] = 1; arr[100] = 100; You have 99 empty elements in that array--that is, there is nothing in arr[2]...arr[99]. You can't do that with a vector. I think the compiler will throw an error. If not, you'll get an error at runtime.

There's not a way of forcing garbage collection that I know of. You can make an array eligible for garbage collection by removing all references to it (e.g., myArray = null should do it). There are two ways of re-declaring it so you can use it over. myArray = []; will do it, as Dave mentioned. myArray = new Array(); will also do it. I believe that frees up the space used by your array, and it can be garbage collected. The Flash VM has its own ideas about when garbage collection happens, though--you can make something available for garbage collection, but, as I said, you can't force it.

RE: [Flashcoders] Array Limit
4000 is not a very small number for array... I have tested it for very high values. and you will hit the loop limit before you hit the array limit. So 4000,1 , 10 array should be fine. For making an array empty just assign myarray = [] And I believe array is the best method to do it And to get the last point var point = myarray[myarray.length -1] -Original Message- From: flashcoders-boun...@chattyfig.figleaf.com [mailto:flashcoders-boun...@chattyfig.figleaf.com] On Behalf Of nasim h Sent: Thursday, August 04, 2011 11:12 AM To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] Array Limit I want to have an array of x,y I use array of object like this var arr:Array=new Array arr[0]=new Object() arr[0].x=10 arr[0].y=22 ..

The maximum size of an indexed array is 232 - 1 or 4,294,967,295. An attempt to create an array that is larger than the maximum size results in a run-time error." > and is there better way to do it I don't know.
