Now that the contest is closed I'm going to start sharing some of the things that are both part of paper and I's entry as well as some of the things I learned as I was trying to accomplish what's in the map proper.
One of the missing things in UT was good, working, fixed, online ready snow and rain. I looked at all the released weather mods and all of them had some sort of issue(s). Some looked great but didn't work online. Some worked online but were made in a way that wasted resources and the longer they ran the more it impacted the server. I wanted effects that could be specifically placed (not zone weather) that looked right but also was coded correctly. Well, here you go:
To use just open the mod in editor and place the SnowActor or RainActor wherever you want the weather effect. Once placed you'll see configurations that will allow you to tweak to your desired level. The actors can be map placed like normal but they are also capable of being tied to something that moves. I fully plan on using these with my Ice and Nature Dragons to give a roaming weather effect that moves along with the monsters as they do their thing.
(Developer talk from here on. If you are a mapper you can skip it)
The source code is included, please feel free to recycle as you wish. A VERY large part of this was done by MasterKent at OU because I was having serious problems getting the particles to recycle properly. A key (but missing) thing for weather is to properly recycle your snow flakes or rain drops. If you don't it becomes a hit to the server over time as all those actors are destroyed without a proper garbage collection (more on that in another post). These new weather emitters are done so that the server gets as minimum a hit as possible, considering you are spawning a couple hundred actors in a very short time. I'm interested in testing this further online, I want to see how dense the storms can be before the server starts to show strain from it. The mod is defaulted to an area of 512uu and 150 drops. This gives a solid effect of precipitation without trying to do too much.
Anyways I hope you guys get good use from these. There's a lot of work in there trying to get them right and I'm really proud they are correct. If you do use these please credit MasterKent in your code. He's a fantastic dude and deserves recognition. I don't care about my work, I'll know it when I see it
