Just something I've always wanted from the game, simple console commands for testing weather.
Specifically:
Forceweather "region" 0 (instantly changes the weather without a transition)
getweather "region" (returns weather id which said region is using)
get gamehour (returns the time of day in it's 24h id, good for if you want to know the time and there's enemies around)
change skycolor 255,255,255 (instantly changes sky colour of current weather to inputted value, will reset when weather transitions or when game changes to sunset/night/sunrise/day)
change fogcolor (same as above, only changes fog colour)
change ambientcolor (same as above, but changes ambient colour)
change suncolor (same again, but changes sunlight colour)
change underwatercolor (same but changes underwater colour)
change cloudtexture "/texturepath.dds" (instantly changes clouds to use specified texture)
togglebrightlights (toggles bright lights similar to in Morrowind's Construction set)
I'd additionally like forceweather, changeweather, and getweather to have "currentregion" as an acceptable input. That would of course detect which region the player is in and apply changes to it. Good for if you want to test something but aren't sure what the region ID is (a lot of vanilla region IDs aren't the same as their ingame titles so it can be hard to remember, plus I can see this being helpful for if you are in a mod added region).
This would be great for testing out new weather on the fly and coming up with new weathertypes without even having to leave the game. I can't imagine the top ones would be very complex to add and would be extremely helpful.
The batch file should be in your Oblivion installation directory (for example, C:\Program Files\Bethesda Softworks\Oblivion) and may contain console commands separated by a line break.
If you are writing a series of commands in a textfile, to be executed with console command "bat" you can use the symbol ";" to indicate a comment, that will not be executed.
I gave the command-line option / config setting a shot.
It's a bit limiting, but should suffice to speed up testing.
On another note is there a way to create a pre-generated character via the console in Morrowind / OpenMW?
If you type in 'coc whiterun' from the main menu in Skyrim you get a pe-generated and equipped Nord character.
That in combination with a few files for the 'bat' command speeds up mod testing and bug hunting immensely.
So I guess both would become more useful once 1.0 is released and OpenCS is done.
