Walkable ship with walkable water

[Legacy_BelowTheBelt]

               I'm trying to simulate a waterborne adventure and one of the things I want to accomplish is a scenario of being attacked while on the voyage by sea monsters.

What I'm looking for is a tileset/placeable combo that would allow me to place a walkable ship "into" an area that has a walkmesh that could go right up to the edge of the boat (in the case of a tileset option).  I was then thinking to use the low/high water placeable to simulate the seas that monsters could spawn in and attack the boat and its passengers.

I could also use a placeable, but don't know what boats are walkable (using CEP 2.3 and the CTP haks).

Has anyone done this before or something similar?

My attempts thus far have not been successful or I've been unhappy with the visual/results.

Thanks!

               You can make places walkable by setting them above or below ground level by a small amount (> 0.1 iirc), and then using invisible wall places to block where you want to block (don't go too crazy with them of the pathing lag will be bad).



As for the tiles, I can think of a number of solutions. Flat tiles, like a city cobble tile, don't have much z, and are suitable for putting water tiles over. Or, you could use tile editing to put in totally invisible tiles, though that's more technical.



Or, there's the simple approach. The very first PW I played on had something like this, and they just had all the spawns spawn onto the boat, having 'jumped on board' from the water already, using a bioware ship tile group.

               So I've been playing around with the null tile options and am liking it so far.



Are there any tile IDs that return a plain black tile rather than the neutral gray of the null tile?  If so, is there a list of what tile IDs are available to use, or are you limited to the IDs of that tileset and the null one(s)?



Thanks!
