Primary Zelda Hacking

Probably missing something obvious, but blade traps seem to stop before the last 2 tiles on the overworld. Kind of necessary for my hack. An attachment is there of the map it won't work on, and I have tried it with no walls on the map, with the same effect.

*EDIT* Placed to the right of this invisible line of pixels, the same thing happens, blade traps cannot pass it for some reason.

I think we need more context, but I do recall that blade traps only go so far.  Did you try an orange trap?

Yeah, they were originally orange.

Essentially, from what I can tell, Blade traps do not work properly on the overworld, and treat a 2 lines of pixels, one vertical and one horizontal, as a wall for collision detection. These lines of pixels are approximately the same distance from the bottom and right sides of the screen, respectively. I really have no idea why this could be, perhaps a bug in the code for their behaviour? Anyone know what address I might find their code at?

*EDIT* It seems even some dungeon rooms have this bug. Damnit, this is annoying.

It's not a bug.  The blade traps actually do not travel the full length of the screen.  If they did, the traps would actually pass through each other.  The first LOZ game has this too.  Did you try experimenting with all the traps available?

Furthermore, could you please tell me what room this is in?  Did you check to see if any interactions might be in the way?

I've been deleting all interactions as I go along. I don't have the file I was working on as I'm at school right now, but I believe it was dungeon room 0 that it wasn't working on in-dungeon, and maps 01, 11, and 12 on the OW.

Eh, I'm just going to use less blade traps, it really is a pretty lazy way of making difficult dungeons.
