I am interested in making a strategy game focused on pre-colonial India. But I am at a loss on how to make a clickable interactive map with tiles of different sizes. I want to make each parcle of land able to be re-textured as it is captured. All I know how to do is make rectangular or square tiles that are all the same size.

I would be thankful for any help.

It gets a bit tricky, you'll have to use larger images instead of tiles and find a way to check pixel collision when clicking it. To re-texture your land images you can use Set Sprite Diffuse or use Memblock to modify each pixels.

I would recommend encoding all areas on the same bitmap using different color values to represent the different areas that way you only gotta pick at the one image. That could also possibly help with highlighting different areas aswell. Good luck!

I went ahead and tossed together an example of the method i was referring too. I didn't comment it but it should be fairly easy to understand.

In this example, I made a 'clickmap' that utilizes only the red channel for storing locations. I've setup 4 areas: a red area, a green area, a blue area and also a background area for everything else.

Heres the code and below is an attached rar with images that you can test it with.


hope it helps!

edit: BTW, i saved the clickmap as a png with no compression. I havent tested it but i'd assume that colors may become inaccurate with various compressions.
