Question by MountDoomTeam · Oct 03, 2012 at 05:47 PM · arrayfunctionstartpushwork

Declare array in other function = error

Declaring an array in Start() is fine:

 function Start () {
     var array = new Array ();
     var val = Vector3(1, 0, 0);
     array.Push(val);
     print (array);
 }

however adding to the array from another function doesnt do anything, it prints an empty array:

     function Start () {
         var array = new Array ();    
         adding();
         print (array);
     }
 
     function adding()  {
 
     var val = Vector3(1, 0, 0);
         array.Push(val);
     }

Variables must be declared outside functions if they are to be accessed by more than one function. Also, don't use the Array class. Use built-in arrays such as int[] for fixed-size arrays, or generic Lists otherwise.

thanks. i just wanted to code a dungeon generator in under an hour, so i thought it should be possible to use the .js array as it is abit easier. ok no worries. the other array is easy also, i just was challenged that i couldnt use the .js one !

it was just to check a concept out taking $$anonymous$$imum time, will rewite to builtin in necessary. in end managed slow array by declaring both outside of functions: and using in both fcts thanks!

   var mov : Vector3;
   var array = new Array();

Use List ins$$anonymous$$d of Array; it's just as easy, but has much better speed and is less prone to errors.

 var list = new List.<Vector3>();
