I render more than just the central map piece now ... and it is now an isometric view.
There are still quite a few problems with it:
I do not wait with rendering until all the images have been loaded: I update the map each time one of the 9 images is loaded.
That means it will render the map several times with errors. Not exactly a bug, that is more like an unimplemented feature, right ?
I wanted to render without a grid, but the way I do the seams now does not allow that. I draw edges that lead to stripes in the resulting composed image. I would have to know something about the neighbor landscapes (or have access to the full map) in order to deal with that problem.
Pretty happy with the progress ... next on the list:
- Actually create items in a scene graph and use it to offer a controllable camera
- MOBA areas placed in a pseudo random way to get playable maps with bases, jungle spawns, special item spawns, lanes with arenas, sneak paths etc.)
