I''m creating a 3D tile "isometric" game. One question, Im thinking of making the level editor use a 3dimensional array of "blocks", or 3D models of terrain for creation of levels. Once a level has been created it is then "compiled", by taking blocks of the same type & combining them together. i.e 2 squares would become one rectangle. Then saving this "terrain model" to a seperate file name, which will be loaded by the game. Is this a good way to go? Is there a better way? Thanks -Vulcan
