Duplicate array

Hello,

Please can anyone tell me the best way to duplicate an array and then push it into itself ??

Do I need to use concat or is there a way I can keep the original array ?

Thanks in advance

Correct answer kglad

my code is just fine, but I would like to create 96 tiles instead of 48..

Two of each instance.


if you want 96 tiles, increase one (or both) of your for-loops so you create 96 tiles.  that has nothing to do with array duplication.

arrays are variables.  their elements point to objects but are not the actual objects.  if you want more objects, create them.  if you want more object references, duplicating array elements or an array might make sense.

use slice():

var duplicate_array:Array=original_array.slice();

and changes to duplicate_array will not affect original_array (and vice-versa).

so after this I could just use

for(var i = 0; i <= duplicate_array.length; i++) {

     original_array.push(duplicate_array);

}

to push the duplicated array into the original one ??

you could but you probably don't want to do that.

what are you trying to accomplish?  are you trying to double the length of original_array by duplicating each element of the array?
