lively rivers

[yorick]

Well, it's not exactly the same as the original spec , but here it is:
Lively Rivers, rivers that actually flow and flood and terraform when they are blocked

You can place the sources in the scenario editor with ctrl-canaltool on any tile higher than sea-level.

Screenshots:

Just placed the source, and it has already flooded one tile. it's now about to terraform the tile ahead.

screenshot #2: as you can see, the river has flooded some more, and terraformed the obstacle on the first screenshot. I also placed some obstacles to demonstrate path changing, and it changed its path once by itself

It's currently really alpha, so don't expect it to work stable-ish...
Also, when a tile with a ship dries up, it changes into a normal river.

Good luck

Known bugs:
sometimes collides into itself and forms a lake

Edit: new version, savegame compatibility broken because of trunk savegame bump

[Gremnon]

Intriguing... does a river placed like this in the editor continue to flood if you pause, save the scenario and then start playing the scenario?

[yorick]

A river will only flood if it does not have a path to sea, so if you save a scenario when it is not done yet, it will continue ingame, it will also do that when your touch one of it's tiles.

[Lilman424]

If you, for example, lower the other side of the lake (the NW or N wall, depending on how you think of it), does the river then flood that way as well?

[Yexo]

Just load this scenario in the scenario editor and it'll assert soon.

Woot, sounds apocalyptic!

What does it do when there is something within the path of the river? Will it raze its way through cities and stuff (hell, this would be mad in multiplayer...a river flowing down from a high hill would become an ultimate weapon against opponents)? Can it get wider than one tile?

[PhilSophus]

Nice one. There already was a similar patch a long time ago (before rivers were even introduced), wasn't there?

Just a thought: Shouldn't the the river dam up to a lake until it overflows rather than breaking through? That would probably produce even nicer looking landscapes.

Nevertheless, great work

It can't get wider than 1 tile for now...and yes, it will raze it way through cities and stuff . If there is something in it's path, it will change path, and if it doesn't work, it will terraform the tile ahead.

[Gremnon]

Watching it do that, it reminds me suspiciously of the standard AI trying to build a rail route... and I think something in that might be what causes the assertation.

So it will raze through 15 levels high mountains if you put it into a level 1 crater sorrounded by 15 level high terrain?

Hey, it takes rivers millions years to accomplish such feat. Ho fast is that in your patch?

[Gremnon]

Pretty fast when I tried it... and definatly destructive.

[Expresso]

Interesting, but what's to prevent someone from trying to wreck havoc on the beginning player?

[Giles]

once again another good one from Yorick this sounds great.
I have a question though once it hits the sea i assume the destructive element disapates rather than continueing onto the next landmass otherwise that could be massively destructive

Maybe it should be given massive costs, I don't know...

Yes, it stops at the sea

[athanasios]

If you could add this in the land generator it would rock even more.

Nooooo! Make the ship blow up instead
"News message: 800 people dead in 6 ship explosions because the river dried and there was not enough water to extinguish the fire"

Or how about this?

What about not allowing people in multiplayer to place rivers.

What happens if someone deletes a part of the river and builds there, does it change direction or plow back over that square?


Cool Idea I'd like to see this in the stable OTTD (or as a GRF file). Thumbs up from me

[CommanderZ]

But I guess if you change terrain along the river it will change its way, won't it?
