Man... it makes a DIFFERENCE.

[@KKAltair]

Thanks! :) It does! :) And the most fun consequence is that we'll be able to double amount of textures and object types (including monsters) in a level.

I can't believe my eyes, really. All this on a plain A500? Incredible!

[@h.h.2198]

Your work is absolutely amazing. When I imagine how doom looks for the 3DO your game for the Amiga500 is a masterpiece. If you had produced this game in the early 90ies, you would have been billionares today!

[@lechistanskiswit320]

TOO GOOD TO BE TRUE!!! 19/10 Can't imagine what those GODS would do with next-gen machine like A1200 AGA 2MB.

[@RetroDavePlunder]

This is incredible, you guys are so good at inventing magic tricks that seemingly noone had thought before, but make complete sense even to a non coder and one has to wonder why nobody came up with them and used them in the many Amiga commercial FPS games in the early nineties. If Dread came out in 1993 for my A500 1mb, my SNES and Genesis owning schoolmates would have crapped their pants in envy

[@KKAltair]

I have played the Citadel and Death Mask back then, so I know exactly what you mean. And that's what motivates me to keep at this project.

[@valenrn8657]

For Amiga's main western European market, SNES's release was in 1992 just like Amiga 1200/4000's release year. Stock Amiga 1200's doom clones such as Gloom and Fears has several major issues 1. Run poorly e.g. Gloom, Fears, Citadel 2. Doesn't look like Doom e.g. greenish color Gloom, Citadel. 3. Bad gameplay e.g. Fears. A1200 needs Fast RAM to speed up Gloom and Fears. Citadel is too slow for A1200 with Fast Ram. Doom clone's frame rate performance on stock A1200 needs to be SNES's Doom port level. kzbin.info/www/bejne/g6S4eGudmcStprc Without Fast Ram, 68EC020 CPU is like 7 Mhz with a 32-bit bus when sharing the memory bus with AGA. The stock Amiga 1200's CPU wasn't 4X over Amiga 500's CPU which is shown in SysInfo's benchmark. AGA wasn't designed without Fast RAM. Dread on stock A1200 was claimed to run >20 fps range which is smoother than Gloom and Dread has "look-n-feel" like Doom. Most of the Doom clones on the Amiga need at least Fast Ram or 68030 @25 Mhz with a Fast Ram, but Commodore didn't release official SKUs such as A1200 with Fast Ram, A1200/68030 with Fast RAM (Mac LC III competitor), and A1200/68LC040 with Fast RAM (Quadra 605 competitor with $1000 entry price). The official Mac 68k Doom port needs a 68040 class CPU as a system requirement and Apple has prepared for it with Quadra 605 competitor with a $1000 entry price in H2 1993. Commodore was selling $400 68040 board as the price difference between A3000T/030 and A3000T/040, hence $780 A1200 with 68LC040 + 4MB Fast RAM official SKU could have been released to compete against H2 1993 era $800-$1000 486SX25/SX33 based PC. A1200 with 68LC040 + 4MB Fast RAM official SKU sets up the infrastructure for 68060 and 68LC060 since it shared the same CPU socket as 68040 which reduces the need for or delay the need for a non-68K Amiga Hombre chipset. I have A1200 with TF1260 with 68060 @63Mhz to brute force run Amiga's Doom clones, just I have done with Pentium 150 for PC Doom type games. Good Doom clones like Dread for A500 and A1200 would have countered SNES's SuperFX official Doom port PR at the lower price segment. Commodore was pincer attacked by SNES from the bottom and H2 1993 era $800-1000 486SX PCs from the top. Apple's Quadra 605 countered H2 1993 era $800-1000 486SX PCs, hence giving time for Apple's PowerPC transition.

@@valenrn8657 I always thought there was a gap in the Amiga range which the PCs of the Doom era seemed to fill. I had an A500 then got an Escom A1200 for £400 which considering what it could do work wise was amazing compared to a PC (which didn't exist at that price) but there was nothing until the A4000 which was megabucks. Something in the mid range with an 040 or fast 030 and proper marketing behind it would have worked. And perhaps a 2 years before Escom!

[@ilmenit]

simply incredible! Minor comment about the scrolling sky. I'd propose to keep rotation only according to player orientation, because now it breaks illusion. To explain why - if the clouds are going to the right then after turning back (180 deg) they should move to the left.

[@PixelShade]

this was actually the first time I saw the sky in action. sky settings will be configurable on a per-map basis, and all of us agreed that static clouds would be better for these large clouds. Personally I would like the scroll speed to be half of what it is now, to give a better sensation of depth and space, which would also reduce repeatability... however, the image is currently hooked to the horizon, so making it half speed would break a lot. hehe, I don't know if it will be possible yet (perhaps using the autoscroll in reverse to player camera to slow it down?) . but it would be nice to be able to set scroll value for each map. depending on background.

[@u9vata]

Awsome project! For the doubling trick: Please just turn "new" off for things that are close and turn "old" for them... Basically implementing both algs and run this for long objects being sampled and run the old for close ones... Those stripes killing everyones eyes! I know what you say about mipmaps, but maybe not just doors and switches should have mipmaps, but for everything it should be "old" for close objects. (see before 8:44) Other tips: - Some doors could be made auto opened or opened through a terminal which is a sprite. This would make players not always go so close anyways. - I see heavy stripization when you fire the rocket launcher for the time the rocket is still too close to the player. I advise you put a sprite in place of the first few moments the rocket travel, then basically turn it off and start the rocket further away from the player. This would give totally smooth animation and likely would not cost memory because the sprite exists, just show it up as a hardware sprite with full size (if does not exists, maybe still best if the shot starts further and there is something handmade in its place for the first few moments of travel)

[@loganjorgensen]

Looking most excellent, the readability increase is great, nice to hear from everybody involved. ;) So hard with details and text at such a low resolution that seeing how that can be done so well is inspirational with my own projects. :)

[@Jammet]

What would be nice to see, would be the equivalent of what in DOOM were called "Hell" textures, and "Clean" textures. All the new textures are relatively busy. In classic DOOM there were relatively clean, shiny metal surfaces, which could be used even when mis-aligned, or in small, cramped areas, to fake writing on the floor, or even to make a room appear as if it was made entirely out of a shiny metal surface. Also, there was another made to look like it was from rusted metal, but had no other features on it, like knobs or bars. There were bright red walls in the Hell scenarios, organic looking stuctures, and demonic ones. I know you're not making "DOOM" per-se, but variety like this, would help a good bit to make maps that appear much less repetitive. Colours are key here. If you find a way to tint all available textures in varieties of red/blue/green or desaturate them, using variables, you give a mapper a powerful tool to alter the mood of every place, every corridor.

[@PixelShade]

I think we need to look at Dread as a two separate projects. First project is the engine development, were the engine improves over time and we as artists can grow as well as experiment on graphics and workflows (improving our skills in conjunction with the specifications/restrictions of the engine) We will also be able to provide ideas for KK to further improve the engine from the eyes of artists. The engine project will use revised freedoom assets, and will eventually be released to the public (that way people can make their own games/mods). The next step... or the next project.... is to make Dread a unique game for the Amiga. When we come to this point only key assets will/might be transferred from the engine project, and we will take everything we have learned along the way and do a complete overhaul. Making a good frame story, a cohesive art direction. Because currently I am kind of lost due to the lack of art direction in the freedoom assets, it's just a melting pot of various amateur artists styles. The main limiting factor today, both for me and John is that the freedoom palette ( 16:28 - 16 colors total) it doesn't allow for a lot of color ramps, so, what you are asking in terms of color variety is near impossible today. there's only one stark red color for "blood"/"eyes", two stark blue colors for "visor" and "projectiles" etc, one green color, and most of those need to be combined with brown and graytones to make sense.... The palette needs to be reworked from scratch. I can agree about the "business" of textures. but it is also a thin line to walk since flatter textures often end up looking cartoonish instead (especially when using 16 colors)... We have tried and it does depart a lot from the Doom-look

@@KKAltair are you in need of more lowres textures? I made around 1700 33x33 pixel textures between 2002 and 2006 for a hobby game I was making in VB for Windows XP at the time (WinDASH). It never got finished, but I have since used my textures for other stuff, for example as textures for a set of 10 3D monsters I am creating for GZDoom at the moment. I actually have made 20 3D monsters now, but I selected half of them since I just needed 10 for my current project. A lot of the textures are suitable for a Doom type game.

@@KKAltair it seems youtube is hiding your latest comment from me, but I read it on my email.

However, you may also have a sufficient texture supply... Also I don't know how well they would translate to the dread palette. Some of them didn't translate well to the doom palette when I made a quick test texture wad with my WinDASH textures and converted them to the doom palette using slade.

[@IsaacKuo]

This is awesome! I guessed the trick for boosting the perceived horizontal resolution, but I feel like it's not really accurate to say it boosts horizontal resolution. I feel like what it's truly doing is boosting the number of texture colors. Instead of each pixel-pair always having the same color, pixel-pairs may have split colors. So, I think it's more like a sort of anti-aliasing than boosting resolution. It's just that at one precise distance, this anti-aliasing effect interacts with a different aliasing effect to produce a true higher resolution. Oh, whatever. The important thing is that it looks great.

[@johntsakiris3717]

That "antialiasing" effect you're mentioning is how the textures are scaled as they get smaller and smaller at a distance. This has nothing to do with the resolution and it would work the same way, either the game was 2x2, 1x2 or 1x1 res (granted there's no 'mipmapping' involved with the scaling). Now Dread actually works under 2x2 resolution, but from the start KK was able to split each 2x2 logic pixel in two vertical pairs and display a "dither" half pixel in there (in an attempt to simulate more colors). What's changed now is that instead of this automatic dither we are actually displaying real texture detail (in each of the vertical pixels) hense practically doubling the percieved resolution to 1x2. So instead of seeing 160 pixels across the screen (with 2x2) you now see 320 (1x2). If you pause the video at the "doubling the resolution" part and closely compare the detail in each of two pics you'll probably see what I'm talking about. Unfortunately the video compression and upscaling here isn't doing much justice to the footage (plus the colors blend together) so it's tougher to notice. ;)

[@KKAltair]

Results vary depending on scale factor. Scaling up breaks things. Scaling between 50% and 100% truly doubles the resolution. And scaling below that somewhat increases the resolution, but not keeping proper pixel sequence (it forces pairs being together).

[@IsaacKuo]

@@KKAltair The lack of proper pixel sequence is why it's not truly increasing the resolution. It happens to work just right at 100% scaling, but at every other scaling it's not right.

[@KKAltair]

@@IsaacKuo It works right for scales between 50% and 100%. That's the range where scaling never repeats pixels and skips one consecutive pixel at most. While it does not keep exact pixel width sequence, it does indeed always keep full pixel or reduces it by half. That's very close to doubling the resolution.

[@IsaacKuo]

@@KKAltair Ah, I see what you mean. You're right, it's close enough. The same trick ought to be used vertically, now that I understand the benefit. It's like the C64 demo trick of doubling custom chars ... it's not "right" but it looks nice.

[@johnnyjohannesson8533]

When I started following this project I thought it looked really bad but was still verry interesting to see how you dealt with all the limitations. But now I'm genuinely impressed by how good it looks, amazing work, can't wait to see how far you can push the limits :)

[@PixelShade]

Me too, that's why I joined. I engine itself was extremely promising, KK just needs a helping hand with the graphics. ;) And like I said, this is just the beginning. first step, John and I are just starting to get to grip with what works with the engine and rendering, and slowly but surely, once the "engine demo" is released, that's when we really start to work with art direction, with new palettes and stuff.

KK/Altair this is a coding work of art! So you've made this Doom clone run on an Amiga 500, and it's BETTER than the best "doom clones" I had on the Amiga 1200 AGA in 1994. This included Alien Breed 3D by Team 17. Also my 1200 had a 50mhz 030 and still was not as good as this. What you have achieved is a *superb* ratio of performance to the hardware it runs on. This code puts the Amiga on par with PCs that existed when Doom came out. Imagine how fast these methods would run on an AGA Amiga with 40-50mhz CPU!

[@davidyoutube1312]

it is even higher, an amiga 500 correspond to a 286 pc, doom on 286 at 8mhz, will not run, and even at 16mhz

[@KKAltair]

Creates texture has thin vertical stripes. What happens here is that these stripes start to be visible from that distance with the added resolution. It does not show on static image, but before they just aliased and flickered heavily at this distance when camera turned or moved.

[@AmigaVR]

Awesome progress.. I'm an Amiga and playstation fan. I would love to play this on my amiga and portable on my ps vita.

[@Chris19744]

Dużo lepiej to wygląda i czytelniej w obecnej wersji ,trzymam kciuki za ukonczenie całości, poniżej parę wniosków/pytań: 1) gra jest reklamowana jako "Doom Clone" a tymczasem oczywiscie bliżej jej do Wolfensteina niz do Doma z wiadomych przyczyn (nie wiem czy to nazewnictwo to kwestia marketingowa, byc moze) 2) w wielu grach doomopodobnych na amige gameplay leżał po całosci (niestety taka smutna prawda), zaletą oryginalnego Dooma było to że był dynamiczny, ze poruszanie w duzej mierze opierało sie o strafe-owanie i fakt ze wiele przeciwników strzelało widocznymi pociskami ktorych mozna było unikać bo poruszały sie z odpowiednią prędkoscią (to dawało jak na tamte czasy mase frajdy) + oczywiscie "trójwymiarowa" a nie płaska konstrukcja komnat. Byłoby miło jakby udało choc w pewnym stopniu przeniesc te mechaniki do tej gry. 3) wiem ze to dodatkowa praca ale czy daloby sie zrobic dodatkowe zestawy tekstur dla roznych leveli , tzn oczywiscie nie chodzi mi o to ze tekstur ma byc wiecej w danym levelu bo są ograniczenia pamieciowe, chodzi mi o to zeby podmieniać cały zestaw tekstur dla kolejnych grup leveli na inny zestaw o nieco innym stylu (kilka takich zestawów bardzo by urozmaiciło warstwe wizualną) 4) Czy jest cień szansy zeby levele były bardziej 3D na wysokosci? (zdaje sobie sprawe z potężnych ograniczen sprzętowych, tak tylko pytam), nie wiem tez czy byłoby to wogole czytelne przy obecnym sposobie wyswietlania podłogi. 5) Miło by było gdyby (podobnie jak tekstury) przeciwnicy dostawali nowy wygląd w kolejnych grupach leveli (czyli w obrębie levelu byłaby cały czas ta sama ilosc przeciwników ze wzgledu na ograniczenia sprzetu ale byliby podmieniani grupami na innych przeciwników). Oczywiscie to sporo dodatkowej pracy.

[@PixelShade]

The Doom-clone is not a marketing thing. The maps are very much based on doom formats, uses sectors, has height data, does use binary space partitioning (like doom) and is not a raycasting engine like wolf3D. :) And it is currently an engine under development, you can see spoilers at 00:57 (stairs) which will perhaps make you more confident about the Doom-like nature of Dread. Enemies uses slow moving projectiles as well, look at the alien head in the last part of the video. :) There will be a lot of improvements as we go along. Although we have come far, it's still just the start. :)

[@KKAltair]

1) It's more about Doom look and feel. Also floor/ceiling levels will be coming, anyway. 2) It's there already! (the flying monster shoots projectiles you can totally avoid) 3) This is totally the plan. 4) Floor/ceiling levels will definitely be in. I wanted to make playable thing first, then develop the engine further. We already had enough engines and not enough games for Amiga 500. 5) This is also the plan.

[@jans2887]

[@KasperSOlesen]

Such amazing work. John Carmack said it was impossible to run Doom on an Amiga, and he even meant 030 Amigas and such, but this is running on an Amiga 500... unless I am mistaken? Just amazing how this runs so well with these graphics, animations and sounds. Mindblowing stuff.

[@dowcipas3801]

Carmack said this but it was 30 years ago and then it was true.

[@KasperSOlesen]

​@@dowcipas3801 that does not make any sense. If it can run on an Amiga 500 today it could have done so 30 years ago.

[@arab3k]

@@KasperSOlesen Much more tricks and hardware quirks unbeknowst 30 years ago have been discovered in the mean time. Thus yes, it's possible now, but wasn't quite possible then (with the knowledge available).

[@KasperSOlesen]

@@arab3k true, when doing things today you have to take into account how much more information is available and how much more freely available that information often is. But I would still argue it does show that it was possible. If skilled developers had had the motivation to focus on this back then, they could have probably done this. Looking at the history of ID Software many of the successes of those developers were them developing new techniques for scrolling for platformer games, 3D effects for FPS games and such. Often it was platform specific and the ID developers were focused on DOS, and their games often never did get an Amiga port. If they had started out with Amigas, and developing for Amigas, I do believe they could have ended up with something closer to this. So I do think its mainly the hardware limitation that should be looked at. Carmack argued that even if he put his focus on it, it would not have been possible to make Doom run on an Amiga, which at the time I believe even included 040 powered Amigas if not 060, because Carmack was not one to let a lack of software coding techniques limit him.

[@pawpw1]

At the moment when he said it, this was correct statement. The only mistake he might have done in his consideration was to list the chunky pixel mode as one of the reasons (now it turns out, this is less of a problem, than was thought). But other than that: he wrote that statement in 1994, after Commodore went bankrupt, and before ESCOM restarted the production of A1200. The most widespread configuration by far was A500, without HDD, expanded to 1MB, back then. For many DOOM levels, the textures and map alone are bigger than that. Yes, accelerated A1200 with Fast RAM would have been capable of achieving a playable performance, but that would mean doing a complex conversion for a very low number of potential buyers. Nevertheless, DREAD is a fantastic piece of technical work and is, IMO, on its path to become the best 3D shooter for < 040 Amigas.

It's worth noting the Red Cross are known to get litigious about people using a red '+' symbol. It's probably why the medi pak has a red H.
