Yeah!!!

There great I love the way you make map Arrays.

But I need some help since the site I am using donsent explain this code to well.

[AS]var mapWidth = map[0].length;  
var mapHeight = map.length;  
for (var i = 0; i \< mapHeight; ++i) {  
for (var j = 0; j \< mapWidth; ++j) {  
this.attachMovie(“tile”, “t\_”+i+"_"+j, ++d);  
this["t_"+i+"_"+j].x = (j\*tileW);  
this["t"+i+"_"+j]._y = (i\*tileH);  
this["t_"+i+"\_"+j].gotoAndStop(map\*[j]+1);  
}  
}  
}[/AS]

I have no clue what that does.

Please Please Please tell me what that does i kno its very important to know what it is.

Please anyone please tell me what it does

That basically goes through an array and assigns a certain “tile” depending on what the value of the array is…

It’s very outdated though and it’s better to use 2 dimensional arrays instead of the method presented… ++i and ++j… Sloppy coding…

Wow Is it possable you could show me a new piece of code to replace that.

If I had the time or effort to I would… But I’m not feeling creative right now…

Just use that piece of code for now… You’ll be fine.

I have been trying forever to figure out why my character goes off the tiles.

Heres the code

```
var downY = Math.floor((_y+(_height/2))/_parent.tileH);
var upY = Math.floor((_y-(_height/2))/_parent.tileH);
var leftX = Math.floor((_x-(_width/2))/_parent.tileW);
var rightX = Math.floor((_x+(_width/2))/_parent.tileW);
var centerX = Math.floor(_x/_parent.tileW);
var centerY = Math.floor(_y/_parent.tileH);

```

I dont know why but my character still goes off the tiles.

I have been mega studying this code and its a shame t dont work well.

Found the Problem.

Its the way you setup the tiles.

I had them way off in the Tile MC.
