Ok.. so I''m working with diamond tiles for the time being and have them drawing just great -- I am drawing left to right, top to bottom. I can drop trees, walls, everything on them and it works great. The problem comes when I have an object moving around. If I move from two tiles adjacent to one another, as the object moves it begins to get clipped by the drawing of the ground plane on the next row down. I suppose I could move the object''s tile location to the lower row, but the calculations to do that would be problematic. Am I thinking this wrong? Should I be drawing ALL the ground plane first, then drawing ALL the next layer, then ALL the objects? I would have liked to draw all the tiles at a certain x,y position, then move on, instead of having to do multiple for loops. Am I missing something here? .. I suppose I could put an objects x/y offsets into the mouse map routine and then change it''s tile location based on that result, but .. hmm. Square tiles sound pretty good here but would still present some problems with having to do bounds checking before moving into a new tile location.. Any ideas?! Or am I fooling myself if I think I can do all my drawing in one pass. Also, do I draw from left to right, top to bottom, or should I be doing right to left top to bottom?
