Summary0000419: Can attack creatures in melee across several Z levels
DescriptionI fought an eagle vs eagle duel in arena mode, and I tried flying upwards to get distance from my opponent, but even across about 5 Z levels, he was able to bite my head. I figured out I was also able to attack and wrestle him back, using the 'A' menu.

Apparently this can also cause teleportation http://www.bay12games.com/forum/index.php?topic=53464.0 [^]

I had something similar in the arena. I was playing one of the flying cavern creatures (forget which one) and as I was trying to kill an olmman, I moved to the edge and past it, which resulted in the olmman falling off. I was still able to grasp and attack it despite there being one z-level of open space between us.

For what it's worth, I have seen this behavior (or one similar to it) in 40d. It was in Adventurer mode, and one of my companions was attacked and wrestled by a cave swallowman more than five Z levels up. I was able to hit him with melee attacks; with the fatal blow, the cave swallowman suddenly appeared on my z-level, and then continued flying off to the side in the standard melee weapon "propelled away by the force of the blow" thing.

Can confirm this kind of thing happens. It looks like creatures can treat targets on different z-levels as adjacent. An Olm-man civilisation is preventing me from mining vertically down to it in fort mode because about ten z-levels up (I know where it is due to the pile of forbidden food 60 levels down) I'll get "miner cancels dig: Interrupted by Olm-man blowgunner". Going to the combat log give the entry "The Miner bats the ({Nether-cap blowdart}) out of the air!" (indicating a successful parry against a ranged weapon) and the location of the combat event is the tile the miner was attempting to dig from, where of course there is no connection to anything except the surface, 50 levels up. Of the Olm-man, there is no sign, even on the units menu.

Any idea if the Olmman had a LoS to your miner? It sounds like it doesn't, but just being sure here.

The olmman is going to run out of darts sooner or later anyhow.

I think this bug is caused when the AI first spots a person, they seem to enter a queued command to attack (which means they charge towards an opponent and hit it), however the queued command doesn't consider moving up or down Z levels as distance and thus they will launch their first attack regardless of what Z level their target is on.

A simple adjacency or pathfinding check just before the creature attacks should solve this.

EDIT - this bug can be easily reproduced in the arena: create an elf and a bat man on opposite sides of the arena, possess the bat man and wait for the elf to start moving towards you and then fly straight up.
