An old bug that still hasn't been fixed yet!

[XMuppetSB]

This old bug has to do with the walk flags for a combo:


A common bug can arise from the fact that enemies will ignore the top two 8x8 walk flags. If a combo has the bottom two walk flags walkable but the top two not, an enemy on there could still go up depending on the combo above. This can cause problems, but should be fixed soon (if it isn't already in one of the the current ZC betas).


It still happens in Build 846. I read it in the ZC Wiki article about walk flags, by the way.

Plus, this bug has been around for a long time... I also noticed a little typo in the article, so I took the 'is' between 'This' and 'can' out of the quote.:rolleyes:

If I'm not mistaken, I think this was kept for Zelda 1 authenticity. Notice how the Octorok in the Level 1 entrance of the original game can sometimes walk through the sides of the tree, even where Link can't? I vote "not a bug," but a quest rule might help sometime down the road.

The left side of the bottom-right part of those trees is walkable and the right side of the top right part is walkable, but the enemies always stop at the solid half of the combo if the solid half is on the left or the right. I even saw them stop at the bottom of a combo whose bottom half was solid.

Read the ZC Wiki article about the walk flags. They said it would be fixed soon, but it's been a while since they mentioned that common bug, and they still haven't gotten around to fixing it, so I've got a feeling that it may be a long time before it's ever fixed.

If someone with too much time on their hands, a Z1 ROM, and a Z1 map editor (can be found at www.zophar.net) would like to test different scenarios for walkability (for Link and enemies) and post the results here, we can fix the code for Z1 compatibility (while preserving the current behavior and providing the correct behavior as well).

I'm on it... unless this has been resolved already.

Well, I did some hacking and checking with the Z1 ROM and found this out (with Octoroks, anyway; I'm guessing other enemies follow suit):

If the walk flags are like this:
XX
X_
then the enemy can walk onto it from the bottom.

If the walk flags are like this:
XX
_X
then the enemy can walk onto if from the left.

If the walk flags are like this:
X_
XX
then the enemy can walk on to it from the top.

If the walk flags are like this:
_X
XX
then the enemy can not walk on to it at all.

Still have to check some other configurations, though.
