What's up with setOvercast? in ARMA 3 - MISSION EDITING & SCRIPTING Posted January 29, 2014 · Edited January 29, 2014 by Meatball So, I did a bit more experimenting and it clears up some stuff, but raises more questions. The speed at which you can up / down in Overcast is directly related to the starting overcast level. The speed will stay consistent the entire time it's going up or down, but that speed will vary based on the starting level. For example: 1) Starting a 0 overcast, 0 setOvercast 1; still goes up about .0167 per minute as I mentioned before. But that stays constant the entire time and you'll reach one in about 60-61 minutes. 2) Starting at .5 overcast, 0 setOvercast 1; goes up just about half at .083. Going from .5 to 1 takes, you guessed it, 60-61 minutes. 3) Starting at .9 overcast, 0 setOvercast 1; goes up at about .00167 per minute (10x slower than when starting at 0) and takes....about 60-61 minutes to reach 1. Starting at 1 and going down works in the inverse with 1 to 0 going the fastest and 0.1 to 0 going the slowest. So, yes, that makes a bit more sense of what it's doing, but it makes it a mess to try to handle scripting of weather.
