NES raycaster (03) - ROM link in the description

[MTd2]

@xtokumaru

That's amazing! Congratz! Where do I get the code for this ROM?

[spyder1138]

Great graphics for the NES! I wouldn't have believed it if I didn't see it!

[du0lol]

So, do we get a source code or what? :D

[deathbyplutonium]

and this would be fully playable on an NES?

[xtokumaru]

@deathbyplutonium Yes, this program works perfectly on the NES. I'll try to post a video of the latest version running on my console soon.

[deathbyplutonium]

@xtokumaru then you need to make a first person shooter!

[CaptainAppleManFilms]

NESenstien 3D!

[Invisibrah]

This would have been so impressive back in NES times...

[shrapnelenema]

i like where this is heading. i have a few questions:

-is anyone doing anything like this for game boy (reg or color)?

-would it be faster (in implementation with enemies/items) to go monochromatic (b/w) with either the wall textures, or the sprites?

-are you limited to one "texture" for walls?

[xtokumaru]

@shrapnelenema 1- Don't know about similar projects for the Game Boy, but I don't see why the same technique can't be used. I imagine you know Tyrannosaurus Tex and Faceball 2000, right? 2 - I don't think further color reduction would help much. The textures are already monochromatic (each kind of wall only has "light" and "dark" pixels) , and the time spent on coloring walls is negligible. 3 - Download the ROM and you'll see it has more textures. Up to 128 textures are possible, I think.

i used to laugh at uncle fester's quest. it had raycasting, but it wasn't really xD just pushing a button changed a frame on the screen :P very clever eh?

[SuperShadow]

Now you're playing with power.

[Dark0Lord7]

@SuperShadow Raycaster power.

[Optimus6128]

Very nice try!

[vacuumnoise]

SOMEONE MUST MAKE DOOM FOR THE NES! And then make it available on cartridge!!

[estlib]

Does your rom use any expancion chips? You know, an expancion chip could very well be another processor to help the NES's own processor (and yes, nes can have expancion chips with some hardware mod but i think you already knew this). That way, you can have a bit more like music, enemies, items, title screens and other such things.

[xtokumaru]

@estlib A scanline counter would allow the floor to have a different color than the sky, and the extended tile attribute mode of the MMC5 would allow up to 6 wall colors per frame instead of just 3. The problem is that the only way to obtain these chips is by destroying original carts, so I'd rather stick to the simpler mappers that can be cloned easily. Title screens and music can be added for sure, but populating the maze with objects/enemies will make things slightly slower.

[estlib]

@xtokumaru hmm... in that case... DOOM PLEEZ :D

[ZenPunk]

@xtokumaru the powerpak emulates expansion chips.

[InsanimationStudios]

I had a dream like this once. Doom on NES.

[FacePlant92]

@InsanimationStudios That would be incredible.. Doom in an 8 bit wolf3D way.. I'd play that allll the time.

[1xWertzui]

I hope this project will be finished. NES is not one of my favourite platforms but its good to see that there are still developments for almost every 8bit systems.

[happygameshow]

would it run that smooth on a real NES?

[xtokumaru]

@happygameshow

It works on the NES just as well as it does on emulators. The timing is pretty tight though, if I give the CPU any more work (with things such as music or enemies) it will certainly slow down a bit.

[SuperFeimer]

That's awesome, I love it when people push the boundries of what machines can do.

[TeamFortressKilla]

If I saw this back in 89 my head wouldve exploded in disbelief

[shrapnelenema]

@TeamFortressKilla this is from '91 KQAhnNiOu54

[boobidee]

maybe if ever put in enemie support and modding tools, I could try Wolfenstein 3d on NES

[GameFreakDude]

HOW ARE YOU DOING THAT

[xtokumaru]

@GameFreakDude

Using look-up tables, combining multiple calculations in one and restricting resolution and colors to reduce the number of tiles necessary to represent all the height and texture combinations. =)

[GameFreakDude]

@xtokumaru ok wow

that sounds like a lot of work right there

can it play doom

[gevelegian]

@xtokumaru You do realise that if you did this while the NES was popular you'd be a millionaire by now right? Sigh...

[CommodoreKulor]

"WARNING: the walls are not solid yet"?

More like "AWESOME: the walls are not solid yet".

I love how it freaks out when you try to walk out there.

Also I think it would be fantastic if you decided to finish this in game form, even if it had to become a little less smooth framerate-wise.

[xtokumaru]

@CommodoreKulor

I really enjoyed your comment, so I have to say I'm sorry for finally adding the collision detection... =)

[boobidee]

NES with 3D graphics is amazing, Soon enough, Wolfenstien 3D could be ported

[achillesian]

wow this would be great for an eye of the beholder type game, great work. Much smoother and easier to recognize depth than other examples.

[inky840]

Hey, that's pretty cool! You never know what you might achieve, keep working on it!

[zaelie]

This is excellent, I'm really impressed.

I'm not that familiar with the NES but I assume all the visible graphics are background tiles. Would it be possible to have sprites in the level?

The main problems I could see is having them scale which would eat up space for different distances, and having them clip behind bg tiles. Is this a proof of concept or do you plan to work further?

[xtokumaru]

I'm not sure if I'll develop this any further. I have thought of a way to locate, scale and draw objects/enemies using sprites, but I won't be able to maintain the same frame rate if I implement *anything* new, so I'm not very motivated...

[zaelie]

Bummer. Are there things that motivate you then? Like a personal game? It'd be a shame for your knowledge to go to waste since you obviously know your shit on the NES, and only a handful of people do these days.

[jeremysart]

I just want a start screen on it that says "Doom" and the Map 1 Doom song during play :-)

[xtokumaru]

The title screen I'd be able to make, but I'm not very good with music!

[jeremysart]

Heh, that would be really cool. If you do something like that, be sure to put up a link to the rom! I downloaded the on you put up, its pretty amazing that first person can be done on such limited hardware!

[PhatPhunk]

This is Incredible! Well done! I never thought this could be possible!!

[Kojote1980]

looks good so far. 3d on nes, hooray \o/

[netsurferx1]

I disgree! I don't think the walls look that bad.

I mean, I know that they're there for "Proof of Concept", but they don't look as bad as you think.
