When was the last time you saw a natural pond/river where the land around it was perfectly flat but as soon as you met water it was eight feet deep?

[Footkerchief]

This should be in the eternal suggestion list thing, seriously.  It comes up pretty often and it's a total no-brainer.

I think I've had dwarves try to path (and walk) through deep water before via ramps. I'm not sure, though; can anyone else say?

I think I've had dwarves try to path (and walk) through deep water before via ramps. I'm not sure, though; can anyone else say?

No. They pathfind over ramps which are water-filled though. Dwarf then freaks out.
Toady can fix this by not allowing water to seep into a ramp. Or maybe something like below:

W = water ; w =water(open space) ; R = ramp ; r = ramp(open space); L = wall ; G = ground

top-down Zlvl1:
wGL
wrL
wGL

top-down Zlvl0:
WLL
WRL
WLL


on Zlvl0, the terrain of the WR could look like this:

W     R
w     w
w     w
w     w
w     r
w     r
w     r
w     r

W has 7 units of water(is full and dangerous), while the Ramp has 4 units of ramp, and 3 units of water(full and safe).

If the ramp construction would half-occupy a square like this, then dwarves could wade through it without fear of drowning.
Heck, brooks could be made to work proper, even.

I realize that adding individual 'ramp items' like this would seriously bog down gameplay, but if we made them a sort of 'half-filled' square and hardcoded ramps and brookbeds like this then it could be pulled off i think. One could ascend and descend by using these ramps/brookbeds on top of a 'full' square like normal.
it would look something like this ;

ramp into water:
W     R       L
w      w      |
w      w      |
w    _w____|
w   |
w   |
w   |
w   |

Or:

one-tile wide brook(B):
L      B        L
 |     w      |
 |     w      |
 |___w____|
>FILLED<
>FILLED<
>FILLED<
>FILLED<

It's a hassle to keep track of dwarves running up and down z-levels, so i added that as a suggestion! Toady, you can maybe use the code for displaying trees as blocks, and display dwarves as maybe rocks of the corresponding colour!
It would make wading through the brook pretty unintuitive otherwise!

[TrombonistAndrew]

Agreed. I had a poor dwarf drown because he couldn't get out of a freshly-thawed pool during spring. So, I went and drained all the pools I could and made the remaining restricted movement so my dwarves wouldn't walk over the ice and get dropped in when spring hits.

Annoying.

And making brooks out of ramps which could only fill to 3/7 or so, instead of some kind of exception to a river square which is walkable, is a great idea. Seconded.

If Toady wants to get really detailed, if the game keeps track of the flow of water in the brooks, places in the brook which get more narrow perhaps are deeper (and thus rampless) to compensate for the water flow. And likewise for rivers, making it possible to have fordable rivers (where it is thus wider and shallower) and some spots in brooks which are uncrossable. More dynamic landscapes always = good.

[Impaler[WrG]]

I think a brook composed entirely of ramps would block trade wagons which we defiantly don't want.  Can someone test this.  But I agree the ramp based brook is a very good way to 'normalize' the brook into the rest of the terrain system while making it shallow and passable on foot.  The current brook might be modified into a  'stream' tile that acts as a water transmitting floor and dose not extend into the lower z level.  This would represent water less then 1/7 deep, streams would almost always be 1 wide and could form when ever water flows over dirt or rough stone for an extended period of time.
