|0005158||Dwarf Fortress||Dwarf Mode -- Jobs, Hunting||public||2012-02-15 21:09||2012-06-19 06:27|
|Assigned To||Toady One|
|Target Version||Fixed in Version||0.34.11|
|Summary||0005158: Dwarves try to cross the edge of waterfalls because water is shallower there, get swept over|
|Description||my hunter died in the bottom of a waterfall|
then I killed the process and start a new game at the same place. and he stepped into the water fall again
Reminder sent to: Rinick
Are you sure you're not getting swept into the waterfall by the river's strong current?

saved game: (use Ironhand Graphics 0.61 temp version)
It's a saved game BEFORE the hunter walked into the waterfall.
I figured out why it happened.
The upper side of a waterfall won't have very deep water (usually depth 2 - 3)
And all drawfs think it's a walkable path.

|Yep, I lost an entire embark to this earlier today. Dwarves would attempt to cross the top of the waterfall where the depth was lower and get swept to their deaths.|
|Thanks Rinick, that clears things up.|
|This applies to Adventurer Mode as well - attempt to cross a river near a waterfall, and watch as your companions all head sideways along the river to the "walkable path" and get themselves killed.|
|I've forbidden the end of the waterfall, and built bridges so that there were viable alternatives, but I could still get rid of my enemies by this pathfinding bug. That kept my dwarves from walking in. However, when I had my first trade caravan visit, after the liaison worked out a trade agreement with me, he decided that fording the river was the way to go. So simply forbidding it is not a good enough work-around.|
|Same here with every embarked dwarf eventually drowning by taking a dive off the waterfall. I would guess that the addition of ramps to rivers in this release made the dwarves "think" this is a valid pathfinding option despite restrictions, bridges, etc. especially with the low water close to the falls.|
|Until this is fixed, you can avoid ordering anything on the other shore before building a floor or over the edge, (carefully, or you'll kill your mason), but still, I tend to lose my cats to this before I could build it…|
|A wall on one side up until it reaches 7 is probably better, when it's removed it won't drop the materials you made it with into the river, and you're less likely to kill dwarves.|
especially bad if you want to build a north-south bridge (you on the north), dwarves want to build the southest floor from the south, crossing the waterfall. not even restricting helps, only a wall
X is the missing part
|I don't know if this problem can be fixed. The best solution would be to have dwarves and companions treat flowing water as being more dangerous than deep water, but flow is an on/off tile property instead of a velocity, so making them avoid flowing water would make all natural rivers uncrossable, with or without waterfalls. The calculations to either treat flow as a velocity with magnitude would kill the framerate, but so might NPC attempts to detect the difference between a shallow river and a waterfall.|
I've fixed it in my game for now my using DF Hack's deramp on all the ramps along the water (a lake in my case).

|Actually, that didn't work. Despite my depot saying that it is accessible, I just got the error message that the wagons had to bypass my site. :(|
Depot access tells you what tiles have access to the depot. You need to make sure an edge tile is green on the depot access screen.
Might the problem said to be that water levels lower before waterfalls? I don't think that happens with real waterfalls.
I've encountered this bug as well. An immigrant potash maker and one of my two legendary miner/engravers went over the waterfall for reasons I couldn't figure out. I didn't have anything on the other side of the river they might be going to and the miner was tasked with smoothing my dining room at that time. I am uncertain as to why she was suddenly outside the fortress near the river. I got a "cancels drink: dangerous terrain" message for the potash maker. Also strange, as I had booze in my drink stockpile and he wasn't injured or sick.
I built a bridge over the edge of the waterfall and haven't had a repeat occurrence, but still unfortunate to lose my miner for no reason.

|If the game removed the ramps into the river for the few tiles before the waterfall, that should fix the problem.|
Another side effect caused by this (?) bug: large fish (such as carp) apparently drown at the edge of the map in the 1/7 water. This only happens on the downstream edge, naturally.
I don't know if this happens at waterfalls, too...
