Correct Isometric block spawn

hey jgo,

how can i fix my isometric block engine so that it looks correct?

here it is now:

here is the code used to generate


size=32;
  for(x=1; x<width*mapSize;x+=size){
	    	  for(y=1;y<height*mapSize;y+=size){
b.addBlock(new ObjTest(x,y);..this is what is being made


}
}

any help would be awesome, thanks
