Isometric objects

Hi everybody

I have a little problem with my isometric tile chat beceause i cant get object that are bigger than one tile on mij stage beceause the depths dont seem right then.

This is wat i have at the moment:

But as you can see the building intersects with the wall.

I heared this could be fixed with masks or a second map array

But i dont know how to do this.

Here is my code for making the map:


myMap1 = [[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],
    [1,2,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
    [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]];
game = {tileW:20,tileH:20}
game.Tile0 = function(){};
game.Tile0.prototype.walkable = true;
game.Tile0.prototype.frame = 1;
game.Tile1 = function(){};
game.Tile1.prototype.walkable = false;
game.Tile1.prototype.frame = 2;
game.Tile2 = function(){};
game.Tile2.prototype.walkable = false;
game.Tile2.prototype.frame = 5;
char = {xtile:2, ytile:2, speed:5, moving:false, height:10, width:10};
function buildMap(map,username,geslacht,admin){
 
 _root.attachMovie("mouse","mouse",2);
 
 _root.attachMovie("empty","tiles", 1);
 
 _root.tiles.attachMovie("empty","back",0);
 
 game.clip = _root.tiles;
 game.clip._x = 268;
 game.clip._y = 235;
 
 var mapWidth = map[0].length;
 var mapHeight = map.length;
 
 for(i = 0; i < mapHeight; ++i){
  for(j = 0; j < mapWidth; ++j){
 
   var name = "t_"+i+"_"+j;
 
   game[name] = new game["Tile"+map*[j]]();
 
   if(game[name].walkable){
    var clip = game.clip.back;
   }else{
    var clip = game.clip;
   }
 
   game[name].depth = (i+j)*game.tileW/2*300+(j-i)*game.tileW+1;
   clip.attachMovie("tile",name,game[name].depth);
   clip[name]._x = (j-i)*game.tileW;
   clip[name]._y = (j+i)*game.tileW/2;
 
   clip[name].gotoAndStop(game[name].frame);
 
  }
 }
 
 var ob = char;
 
 ob.x = ob.xtile*game.tileW;
 ob.y = ob.ytile*game.tileW;
 
 ob.xiso = ob.x - ob.y;
 ob.yiso = (ob.x+ob.y)/2;
 
 ob.depthshift = (game.tileW-ob.height)/2;
 ob.depth = (ob.yiso-ob.depthshift)*300+ob.xiso+1;
 
 game.clip.attachMovie("char","char", ob.depth);
 
 ob.clip = game.clip.char;
 
 ob.clip._x = ob.xiso;
 ob.clip._y = ob.yiso;
 ob.clip.gotoAndStop(ob.frame);
 
 ob.clip.mouse_over.name_txt.name.text = username;
 
 /////////// =======> connecten met chat  <======= /////////////
 startChat(username,geslacht,admin,ob.xiso,ob.yiso);
 
}

I hope someone can halp me with this problem.

Sorry for my bad englisch
