River graphics needed! (8bpp)

boekabart · Post by **boekabart** » 24 Apr 2007 12:47

Hi GFX artists,

I made a lake+river+deep-see patch. Please it check out http://boekabart.googlepages.com/deepwater or the topic about undersea tunnels on the ottd/development forum.

To finalize this patch, we need graphics for the 'waterfall' tiles in those, and maybe sea floor graphics. Anyone interested in doing those, in oldfashioned 8bbp?

Hmmm... I think something could be done with the canal sprites.

And the waterfalls need to be animated.
Cool!

_Ben_ posted this picture on IRC to inspire artists.

Note that the 'yellow' edge on the waterfall must be drawn in the waterfall sprite, not on the steep slope sprite in order to work with my patch. The different types of waterfall... can be done with a little mod, but let's first go for just 1 type!

Do you need steep-slope tiles? If water flows off a corner, does it go over the entire corner, or around it to each side, leaving a dry bit?

ie, does it behave like the left or the right side of this mis-scaled photograph?:

The steep tiles will never flood in the current implementation, and I intend to keep it this way, so that saves a bit of work there.

Hi boekabart

Mountain top lakes and mountainside waterfalls in TTD, a dream come true

Can the lakes be any shape or are they based on the Canal tiles

Great work, Bravo

I was thinking, and curvedslopes should also need their own water graphics. I can make the Niagrafalls! (Well kinda.

)

What are curvedslopes?

This is a seriously cool new feature. I hope it gets into OpenTTD 0.6!

I think he means steep slopes. You've already clarified that bit. There is a problem, though - what if a slope from a lake enters a convex ground tile? One with a steep slope that slopes down from the flat half?

I find that hard to imagine... picture please?

No I ment it so that the previous shown image only shows water falling in just 1 direction from the opening.

But imagine something like this:

i get your point, what about non-straight-down-slopes but bend/cureved ones (dunno if this is the "steep"slope:P)
your point is good, but then you get a bigger waterfall(your version is 2 -3 tiles with and the one shown is only 1.....

boekabart · Post by **boekabart** » 25 Apr 2007 18:44

I get the idea, yes, that would be more realistic. But realize that the flow will spread out a lot like this, rather than go down straight... I don't like that, it makes modeling rivers a lot harder to do. But... how to explain the water 'avoiding' that corner on top there... a sprite with a slightly raised edge maybe, for the flooded version?

Yes I think that would be the best sollution, somesort of innertile dike or something. Not fully 100% realistic but good enough.

well in reality normally a river starts in its spring... so why don't add a special slope tile with a spring and let the river only be able to do its way with a width of 1 tile? dunno if it's possible but imo reduces some "flooding" problems (but maybe generates some other ones). As for the example above with the lake, the spring(s) could be at the coast(s).

Still, more downstream, a lake of this kind could develop. Problem back

I've made this, based on my newwater designs. Maybe you find it appropriate. it's in-game animated (something like this http://new.tt-forums.net/viewtopic.php? ... sc&start=0 )
