In Team Fortress 2, the Engineer can construct buildings. He can build one of each type of building, and they cost different amounts of Metal to build. Therefore, the buildings on his menu can be in one of three states:
- Able to build
- Unable to build because not enough metal
- Unable to build because already built
Here is how the default HUD looks:
I always find that I have to read carefully to find the reason, not a good idea in the heat of battle.
This is how my custom HUD, rayshud, does it:
It just increases the font size. Clipping issues aside, I think a larger font helps a little here, but not much.
Here is how another custom HUD, BWHud, does it:
This one is just weird.
So what's the best way to contrast these states? I'd say perhaps only show the buildings that can be built, but that doesn't appear to be an option.
