Moving a Generated Grid with Keyboard - actionscript-3

Question

I'm trying to move a generated grid with keyboard...
When I try my .swf file, it runs but keyboard...
It's for a platform game as Mario, so you should fine some code lines who haven't sense there, but I insure you they will !
So, this is my AS :
var map:Array = [
[1,1,1,1,1,1,10,0,0,11,1,1,1,1,1,1,1,1,1,1],
[1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
[1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
[1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,7,0,1],
[1,0,0,0,0,0,6,1,0,0,4,4,4,4,0,0,6,1,0,1],
[1,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],

[1,0,0,0,0,6,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
[1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
[1,0,0,0,0,6,0,0,1,0,0,1,0,0,1,0,0,1,2,1],
[1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],

Thank you !

Answer 1

I see a couple of problems right now:
paramMap and its inner function movingGridare never called by anyone. You may want to hook them to an ENTER_FRAME event listener or call them when the user presses a key.
the vit and T attributes of grid are not in this part of the code, so it throws a ReferenceError when I test. Same goes for the checkLateral.
When those issues are solved, the grid object moves correctly. But because it's an empty movieclip, you can't actually see it yet. You need to add visible children to it or move an existing object. Here's the stripped code, correctly moving grid left and right:
var grid:MovieClip = new MovieClip();
addChild(grid);
stage.addEventListener(KeyboardEvent.KEY_DOWN, pushin);
stage.addEventListener(KeyboardEvent.KEY_UP, pushout);
var right:Boolean = false;
var left:Boolean = false;
var up:Boolean = false;
var down:Boolean = false;
var lateral:Boolean = false;
var saute:Boolean = false;
var none:Boolean = true;
function paramMap():void
{
grid.sens = int(right) - int(left);
grid.up = int(up) - int(down);
grid.jump = - int(up) * 11;
none = ! right && ! left && ! up && ! down;
lateral = right || left;
var L:int;
var C:int;
var Ls:int;
var Cs:int;
var A:Object;
var B:Object;
var Y:Number;
var P:Array;
with (grid)
{
x += sens;
L = y;
C = x;
Ls = (y - 1);
Cs = (x + sens);
}
}
function pushin(event:KeyboardEvent):void
{
if (event.keyCode == 38)
{
up = true;
}
if (event.keyCode == 40)
{
down = true;
}
if (event.keyCode == 39)
{
right = true;
}
if (event.keyCode == 37)
{
left = true;
}
paramMap();
trace(grid.x, grid.y);
}
function pushout(event:KeyboardEvent):void
{
if (event.keyCode == 38)
{
up = false;
}
if (event.keyCode == 40)
{
down = false;
}
if (event.keyCode == 39)
{
right = false;
}
if (event.keyCode == 37)
{
left = false;
}
}
