Fog of War
I don't know if this has been done already but here's a little picture I made demonstrating a possibility of how fog or war might look:
Before
After
These pictures are just an example of the fog, obviously it doesn't really make sense for parts of the town to be covered in fog since I clearly own that town :p
Obviously it's a little rough (I no longer have Photoshop, and it shows), but what do you think?
Here are the rules I came up with:
1) Units are invisible in fog
2) Buildings are invisible in fog
3) Roads are visible in fog
4) Trees are visible in fog
This is not always so clear-cut though; what if a building is half covered by fog? We will need one of the following rules:
1) If any part of the building is not covered by fog, the whole building should be uncovered
2) The building is invisible if any part of it is covered by fog
Anyway, just some thoughts. I wouldn't be surprised if it's already been discussed...
