Well, I actually made the mock-up for the moon phases, but... it was ugly. Not because of design, but because of the lack of information of what should be input in the top panel.
I'll show here what I've done with my own mod, which is what I offered Nomad, who told me to go forward with.
This is what the Top panel will show you:
The information it provides is the following:
- What time of day is, and how is the weather (in BC's case, this would show the moon's phase);
- How long does it take to change Day into Night, in turn terms (game speed affects this amount, naturally);
- Spells out the icons (I play on high resolution, so most icons are very hard to distinguish, more people can have this same issue);
- Explains how Day/Night affects the game;
- How long weather takes to change. Although, in this case, weather is a bit unpredictable, so you only get an idea of how long does it takes. The first number (2) is fixed, while the second changes according to game speed;
- Explains how Weather affects the game.
More than just a tip, the player will get notifications on the changes of Day/Night cycle
and weather cycle as well
So information is abundant AND modular!
All the infos update smoothly and immediately.
With that explained, I feel obligated to say one thing more:
Modding Civ5 truly is an exercise in creativity.
Not because we can express ideas and turn them into reality, no, but because we have to dance to Fireaxis music, and this is not a company known for it's beautiful symphonies.
We can't think "A" and apply it to code, sometimes, but think "A", then do "B" and a bit of "C", just so the PLAYER has the impression all we did was "A". Examples? Dummy buildings. I mean, that was a ridiculous shot of creativity! Someone thought: argh, I'll have to make this ugly stuff appear in the City screen in order to give the player the bonus I mentioned in the UA.
Then, someone (or the same person, I dunno) actually got the building to NOT APPEAR in the city screen, and most players are OBLIVIOUS as to how the modder accomplished "A" in the first place. It wasn't by doing "A" (+1 Science to whatever), no it was by doing "B" (creating a building that gives Science to whatever) and a bit of "C" (hiding it in order to keep the illusion).
So, keep on with your spaghetti monster, Fireaxis. Let's dance.
EDIT:
I got too involved in talking about modding that I forgot an important aspect of the system I created: since you can intercept the changing of moon phases, there is no limit* to what you can do with them, as we can create LuaEvents to form the most variated effects on moons phasing in and out.
* It's still a game, so, yeah, there are limits.
nor in warhammer thread. Guess we`ll stick to playing fall from heaven modmods until 2020
