I've places many more than 15 red keys on a map, to give a similar gameplay to Mario where treasure is floating. Keys are the only thing that I can think of that float, so thousands of keys it is.

Oh hey, that's me 🙂 Yes, it's fixed in the remaster. The main issue is that the mirror effect routine unconditionally copies 30 rows of pixels, without checking if enough rows are available on screen

There comes a point where modding an existing game becomes more trouble than just building something new. With Bart vs. The Space Mutants in particular, that game's levels weren't really built to be modified and have a massive number of hard-coded elements, thus if you wanted to make something which was "better" it would be easier and faster to just make something new. :P

Just be thankful I don't do any of the more stereotypical Canadian stuff like "aboot". :P

@@Pixelmusement But YES!!

@@PixelmusementWhy do you and the south park creators spell it that way though? It’s not so much about the o as it is the over pronunciation of the u!

@@nyccollin Because "oo" is visually the correct sound as an "ooh" sound. "uu" suggests a "you" sound which is not what's said. :P

@@Pixelmusement ah ok fair enough! Great video by the way!

Not yet. Never played F29 and never owned LHX and I don't really have a lot of other flight sims. :P

Somewhat pointless just as an exporter for the moment, but if you can get it going the other way as an IMPORTER that's not just curious for me but probably for EVERYONE with an interest in DN1 editing, at which point you may want to get in touch with the people at moddingwiki.shikadi.net/ to contribute the tools you create! :o

@@Pixelmusement I seem to have gotten it working the other way. I dunno how to get a link to you from here but if you want to check it out you can. I haven't extensively tested it and it's not super user-friendly.

@@Aeduo Again, best way to contribute your efforts is not through me but by getting in touch with the people at the place I linked you to! :B

@@Pixelmusement I'm not really up on editing wikis and I don't really want to get too involved in another community, but I've made it a bit nicer to use and added 2 more of the game's graphics formats (seems to be all?) for conversion in both directions. I see on there some other tool already supports it though? Although I think I already left a comment about where to get it but maybe i forgot to post it or it got automodded or intentionally deleted. If you're interested i guess it's up to you, otherwise, I'm probably not going to bother any further.

Comments with links are either auto-deleted if the link is HTTP, not HTTPS, they will also be auto-deleted if they're executable in any way, otherwise they go into a "Held for Review" buffer for me to verify first and then either allow or delete manually. At the very least you should make what you've created available, let the appropriate person/people know, and then just go from there. As for the tool you mentioned which seems to do it, that's the one I tried which does NOT. (It's either been mislabeled or once did work but no longer does.)

Just so we're clear, I've made about 368 videos between that one and this one. :P

@@Pixelmusement: 😇

No... In fact, that shouldn't be possible, but I will admit, I didn't test teleporters enough to know how the camera responds to them so I'm going to guess that's where the glitch is? I'll go test it myself and if that's the case it's an easy enough fix: Just move the teleporter. :B

OH WAIT... I see what the problem is now... Those walls I THOUGHT were solid walls are actually breakable with the gun! Yeah, that's not supposed to be breakable; I'm gonna go fix that and reupload the level! :P

@@Pixelmusement No worries. I didn't want to give too much details in case it was intentional (so that I don't spoil the surprise). Thanks again for the levels and all the best to you!

@@AttilaMihalyBalazs Update is online! :)

WHERE you run it from is important. For "..\" to work the editor has to actually be run while the current directory goes back to the parent directory with the game files. So in your case, make sure you're actually in the DN1MOD directory when you run DN1MOD and so long as the parent directory has the game files you should be good. If you continue to have problems then make sure you haven't installed your DOS games into special folders like "Program Files" or "Desktop" as you may be running into Windows permission issues.

The other problem you may be faced with is that if you're running DN1MOD as a separate program through a DOSBox frontend, it may only be mounting the DN1MOD directory and not the parent directory where Duke Nukem is installed. If the DN1MOD directory is being made the root then any actual parents of it won't technically exist as far as the emulation is concerned!

@@Pixelmusement: Thanks! Your second reply was my issue, I mounted too high.

I didn't want to go over all of them because there's a lot of exceptions, but the general rule of thumb is active tiles take their background from whatever tile is to the left. When in doubt, place an active tile on the world just as it is, then try to place background tiles around it and watch for when the background of the active tile changes; then you'll know for certain which direction it takes its background from!
