A small bug, that has been overlooked for a long time.

[Rydia]

Ok, I have noticed something just recently that I had noticed a while back. I have a couple pictures to help me explain, since I totally suck with words. Ok in the first image, you see that bar thing from Zelda 3? In the second it is highlighted pink in the ZQ editor. Everyone knows that this is because it is solid, and Link cannot go through it. Now for the problem, see, Link can't go through, but enemies and walk vertically through this. I have observed this many times over.

[NerdWarrior]

Yeah, this one's been around since 183. I think I've reported it in the past, but it must have been forgotten or something.

I forgot to check for this one myself in the newest release. -_-;

[4matsy]

Not just 1.92.183, but 1.90 as well. o_O

Seems enemies don't check the bottom of the tile for walkability, but do check the top...

[Dart Zaidyer]

This bug does exist in 2.10. I just saw it today.
In fact, it doesn't even matter which half of the tile is walkable or not, they'll still ignore it.

I had always thought it was standard behavior on LoZ, but apparently it's not. (seeing as how there are no such situations in LoZ anyway...)
Better put this in the list.

[Praethus]

I'm pretty sure the bug only happens if the top half of the tile is unwalkable. If the bottom half is unwalkable, I think it stops enemies.

[fatcatfan]

And I think this had been fixed at sometime in the past. The question is whether it is behavior that you'd see in Z1.

[4matsy]

Probably is. Octoroks have been notorious for going through the bottom left corner of the wall directly onto the stairs, on the screen 1 south of 1st quest level 2...

[ShadowTiger]

... *Blinks* ... I've never seen anything wrong with that, personally. Octoroks may roam where they may roam... Of course, this problem here, (And I believe the correct functionality of this is situated in Praethus's explanation, with the top being unchecked.) could be used and exploited by ZQuesters. You could place those small unwalkable borders (Like in HL's shot under the walkability red part.) so Link would have to walk between two tiles, and no enemies could get past that position. You could use such a place to attack death knights (If everything else was positioned correctly so that was a safe spot, of course, from the Death Knight's vertical sword beam attacks.) So this isn't really as much of a bug, unless you consider them passing through the following, with X being unwalkable, and X being walkable.

In that illustration, if an enemy walked SOUTH onto that tile, THAT RIGHT THERE would be the bug. (You all know that, .. heh.) anything else wouldn't be a bug though. This is really the only instance of this bug that I can see, that would truly BE a bug. Also note that they can walk horizontally onto such an incidence, in the above, but they cannot walk horizontally (Or at all) into the following incidence, including a horizontally flipped one.

Enemies trying to walk horizontally onto that wouldn't be able to at all, bug or no bug.



So the only bug here that we must fix, is the first diagram I drew.

[Praethus]

BH4, the problem is they do walk south over that. Make a screen full of combos designed like your first diagram. The enemies will have free range of the screen, while LInk will be constrained to one row.

I've had to work around this bug a lot. Since Zelda 1 seems to behave in this manner, a quest rule to fix it would be nice.

In a similar bug, I recall that the ladder does not observe a 1/2 or 1/4 non-walkable tile on layer 1 or 2 that is on top of water or "ladder only". I'll have to check on it, though.
