steep slopes are displayed incorrectly under industries near water
This task depends upon

This is more like a feature request. And the downside is, that it would break other graphics:
See http://www.tt-forums.net/download.php?id=80066

So either there are only original shore graphics under industries, or only new.
In "slopes.png" it is even more critical, as the additional shore sprites are not available in industry sprite layouts.

Yes, I understand the problem, but I do not know what to do. Could the code understand that a change is required because default land sprite is used? If yes, that would be a solution.

Now what if someone would make their industry create a pier which does not want the shore graphics on them? The major problem is that it's impossible to always correctly guess what the artist had in mind... and as frosch already said: you can't use the shore graphics in the sprite layout. They are not even part of standard NewGRF free OpenTTD, which makes the problem even bigger. Then there's also the issue of "flooding". We don't know whether the tile should be flooded or not, i.e. whether the default steep slope should be replaced with the flooded steep slope, and then there's no space to store the 'is flooded' information too.

Rubidium, I understand, that this graphics is not accessible.
But I hope devs would suggest the best solution for coding. Grf authors would accept any solution here (new action 2, var cation2, something else, a callback maybe)
If you ask for my opinion about that, than I suppose a tile may have sum property (may be a bit in prop 12) to show, that it INTENDS the replacing. Would that be Ok?

Perhaps some special value that means "use a default shore sprite"? We can easily specify that it will not behave like a normal shore tile, because... it's not one.
Comment by George (George) - Tuesday, 06 January 2009, 12:09 GMT
Peter, you mean a bit in prop 12 to specify the behaviour? So, 0 would mean to use replacement, while 1 would mean use default graphics? That's fine :)

I still do not see a way, how OTTD could decide whether a tile is a shore tile or a grass tile. Especially due to autoslope and inner industry tiles, which are only surrounded by other industry tiles, i.e. not connected to water.

Maybe the land info of nearby tiles can be extended to distinguish sea from river/canal. Then the grf could check itself and one would only need a way to specify shore sprites in spritelayouts.

(Btw. when someone thinks about supporting shore sprites in spritelayouts, one could also think about foundations, resp. generally any action5 sprite. Though problem is, that they are not always available)

Frosch:
I thought about some flag for industry tile, that would indicate it as water tile. This was needed to prevent rivers to draw river shore near such tiles. Possibly (?) it may lead to a problem with ships pathfinder?
From my point of view, the river idea is very inconvenient in general. Instead of changing water tile (drawing shores), I'd prefer to have the changed shore, the same way as seas do.

River shore is suppressed if the industry tile was build on a water tile.

Frosch:
Oh, ..... many bad words. Now, what tests should I do to understand, what graphics should the industry provide? Previously I tested water nearby, but now I also need to test the tile itself, because there can be both variants (with and without shore).
May I ask for a tile flag to force a tile become watered tile if nearby tiles are water (flooding under industry) to force removing river shore :)
