how do you create fog of war?
By programming.
What exactly are you having trouble with?
good answer :wink:
If someone knows they could explain the concept of how to do it, of course it would require programming, Im sure the OP already knows that, and these posts dont exactly help him solve the issue
Have an array, and make it say, 32 times smaller than the screen. Therefore each position in the array is worth one 32x32 tile on the screen.
Now, if an array square is set to 0, it means there is fog, if you switch it to 1, that means the area is clear. Then run a loop to draw out the fog only for the area on screen (you don't need to draw out what isn't on the screen).
A really cheap way to do it is to have a invisible circle around your character that destroys the "fog" particles when they collide. Of course, it depends how you want to do your fog.
To do Star-craft style fog, the above applies to the dark "unexplored" areas. For visible enemies/structures you can detection within a certain radius of your character to make enemies visible/invisible.

You just tore though my joke man... I'm just tired of posts that ask questions in an extremely vague way.Originally Posted by JasonDarby

Another way you could do the fog of war is using the overlay object. Simply clear it with color (0,0,1), then draw (0,0,0) circles around all the objects you want vision from. Just be sure you have the overlay set to transparent. (The overlay would have to be aligned to the screen at the beginning of every frame, but this eliminated the need for a massive overlay that covers the whole map).
You could also have an 'explored but not visible' layer of the overlay, by having 2 separate objects, 1 like how it is described above, and another that draws circles based on a whole bunch of invisible objects that are created wherever a friendly unit walks.
The quickest way I found was to use paint to create a black square with a faded circle in the middle. However, this won't cover for the places you found, just impairs the vision for the player. But, I've never heard of any other examples so this is a big help.
