Rain should wash away blood stains outside.

[Sion]

I think rain should slowly clear bloodstains off the map, because when you are approaching day 100+ it looks like a slaughterhouse wherever the fighting happens, and it really isn't practical to Home Zone the entire map just to clean it.

I was just thinking something similar last night.

Not a guaranteed wipe, but maybe a % chance.  Since the game tracks how long objects have been around (does it do it with blood stains as well?), the % chance could get lower the longer blood has been dried.

Having said that, it wouldn't hurt if fresh blood was easier to clean then set in blood (for colonists as well), blood you wipe up right away should come up easier then stuff that's been crusted on a year.  Maybe surfaces having a cleaning difficulty/time modifier (if they don't already?), as same goes for metal tiles vs carpet vs rock floor, etc.

(grumbling) "Frakking squirrel frakking dying on frakking blue carpet... Why do I have to clean this stuff?"

I think it'd be easier to rip out the carpet and lay down a new one than to clean it. Have you ever tried cleaning blood off of carpet? Without bleach? Or even water?

[SlimeCrusher]

Never had blood on my carpet, so no 

[ITypedThis]

I agree completely.

[Darker]

Yes,  also want this to happen.

I've decided to start working on this, will let you know IF i manage to finish it.

[Jones-250]

Seconded

[Tynan]

You're right, I'll put this in now.

I had wanted the blood to tell the story of past battles, but after a while it just becomes a flood. Maybe it'd be better to clear the ancient battles so you can see the remnants of the recent ones.

[Semmy]

Maybe isntead of blood remaining make it slowly degrade over a rainstorm or 4.

And let bodies decay so skeletons remain.

[Darker]

Yeah, skeletons would be nice. Much more realistic than blood. They should also give fear buff along with the happiness debuff.

By the way, Tynan, how would you implement this? I'm asking because I was too thinking of whole map over-time events and processes, but I have no idea how to hook them.

[Tynan]

This is the BreakdownManager.

It used to do breakdowns for repairs, but that was cut. Now it does electrical shorting from rain and blood washing from raid.

Basically, it just randomly pokes at the map and does stuff depending on what it finds. Not very efficient, and it has some other quirks, but it works well enough.

Thanks, there are also other things I was curious about in this file.

But how would I hook similar thing in-game? Can I have procedural code in the C# file?

[Tynan]

Procedural code? Wha?

What you need is a hook for some sort of global entity that can undertake global operations. Let me look into providing that.

[Darker]

With procedural, I meant something like calling methods of other objects from within nothing.
In Java this isn't possible, and everything chains from the main class - even if you add a code, it must be invoked from somewhere. With rim world mods, everything is being invoked by XML definitions that cause classes being instantiated.
But I have no idea how to add something that is not defined anywhere - like this global events, more pieces of UI and so on.
