What happens when the sea floods into a sub-sea-level area?

maybe destroy and terraform?

Or more place for fish and divers ?

He has a screenshot on the link he posted. It seems to just bulldoze anything below, but stay in the air.

Well, it looks like its en-route to flatten the town...

Nice!
Please consider that sea has depth also. So for long tunnel it is OK, but for short tunnel like in the screen capture you posted entrance should be 1 level deeper.

Actually, the current sea in ottd behaves as if it's a bit higher than flat land, doesn't it. It just isn't drawn any higher. So if we'd raise the sea drawing level by say 4 pixels (half a height), and change the coast graphics to match, it'd be correct again.

But this way bridges over water have to raise and lower to get over water.

edit: this won't be possible anymore:

I don't get what you mean by that. I'll try to make a mockup shot. Offtopic: But you do live really close to me (i'm actually in Wijchen).

Edit: Now I know: raising the water by a couple of pixels requires re-working of all bridge-pillar and bridge-head graphics...

I think we need graphics for a tidal-wave front so that the sea isnt hanging in the air (muahaha).

Seriously good job on this one^^ I hope it becomes workable in the future

Re. the problem with the 0-depth water:
True point, but I think it is acceptable. We currently accept tunneling under canals, and the fact that sea with level 0 floods land with the same level...
Why would we require 1-deep water for tunneling under, but not for shipping and tunneling under canals?

Is a very good idea, It can be used in MiniIn or other version of OTTD.

MiniIN is dead and has NEVER been a version of OpenTTD.

I didn't mean your patch should not be used as it is right now, and I hope it makes it quickly into the trunk. Yet it needs to be corrected in the future and the same applies for the under canals tunnels. I mentioned it, thinking you might find a way to solve the problem.

No, your point is good and taken, and the solution is (in theory) quite simple: don't allow tunneling directly under canals, and don't allow shipping through 0-deep water (thereby forcing you to keep water deeper and dig your tunnel deeper). Maybe turn 0-deep water into swamps?

I hope this is an option that I can leave off. Ie be able to have underwater tunnels but not the other stuff.

Cool! And I was almost thinking it was impossible...

I think this could maybe be implemented, and when the idea is refined about making it more realistic (inline with canals) then this patch can be updated maybe.

Ben_K · Post by **Ben_K** » 23 Apr 2007 10:25

I like the thoughts behind this. I think its a great progression here. I also agree that if we can, make it so that you need at least one vertical unit in between...

Now thats also a good idea.
