Why doesn't this ramp work?
« on: May 28, 2011, 05:09:55 pm »

Thread title question.

My dwarves refuse to walk up/down this ramp. Depot is listed as accessible so the game thinks it works as a 3 tile wide ramp.

excuse the bad cropping this was done in a hurry.

Edit: Oh crap it might be the floor grates :/
Edit2: Nope, not the grates ://

Where's the wall that the ramps go up against? It looks like you have something like this (side view):

___/\___

In order for a ramp to work, it needs to be more like this:

___/W

Basically, you've got a mound of dirt in the middle of a floor there, and you need a mound of dirt against a wall. You've got a speed bump instead of a ramp. The fact that the depot is accessible doesn't matter in this case, as that check doesn't actually know if ramps are usable (probably due to a bug), but lets the accessibility go to other z-levels if there's ramp tiles present.

Will a raised drawbridge work instead of a wall?

No. A wall, natural or constructed, will work. Nothing else.

Additionally, the wall the ramp is braced against must have a walkable floor above it - ramps cannot double-back onto themselves.

The following ramp is valid:
Code: [Select]
█████
██ __
__/██
█████

This, however, is invalid and will not work:
Code: [Select]
█████
___ █
___/█
█████

In other words, in the following scenario, the only traversable path from the lower level to the upper level is by standing on the ramp and stepping to the left; likewise, the only way to get from the upper level to the lower level is by standing on the smoothed floor tile and stepping to the right:
Code: [Select]
Z2
...
+▼.

Z1
...
█▲.

P.S. If you don't get this note, let me know and I'll write you another.
It's amazing how dwarves can make a stack of bones completely waterproof and magmaproof.
It's amazing how they can make an entire floodgate out of the bones of 2 cats.
