How to make my doom 3d ?

Recommended Posts

Someone tell me please what port Doom to take to create a 3D shooter (3D enemies and weapons, etc.) and examples and lessons how to do it ?

 

I just want to create a 3D shooter with my 3D models of monsters,weapons,scenery  using the level editor gzdoom builder      is very convenient judging by the lessons on youtube.

 

I want to create multiple levels with the level editor gzdoom builder for my shooter just by replacing textures and sprites sounds with music and have this shooter run as a standalone game through the free doom port

3D models? Good luck. Even with modern source ports, putting in 3D models is very difficult to do. GZDoom Builder doesn't even support OBJ files.

I saw 3d monsters in Risen 3d port and I want to make 3d monsters like there but don't know how.

You want to learn how to make your own 3D models? Well, go to YouTube and search for videos on how to make 3D models.

Blender is a pretty solid choice for 3D modeling.

 

Modeling is a big topic though, and not something we can just tell you how to do. Start by Googling "Blender lessons" and be prepared to put a few hundred hours practice in before you start to feel confident. 

 

Once you've got the basics down, this is a pretty good guide for the GZDoom part of it.

3D Model's aren't toooo hard to work with, but do take a good bit of practice to nail it.

 

Firstly, make sure your model is either a .md2 or .md3 (Personally .md3 is better but that's just because I'm used to it). There is an extension that can be added to blender that allows you to export .md2/3 models.

 

Now, assuming you know how to model and texture models, next you'll want to export your model SPECIFICALLY as a .md2/3 (I'll show you the .md3 way), making sure it's reference is set to the Y position (should be on the left side of the export screen).

 

 

In slade3, create a new FOLDER and save it as a .pk3 (wad files can't handle models very well). Next, create your DECORATE.txt and a folder names "models" (NO CAPS!)

This is what it will look like

 

For the DECORATE.txt file, fill it in like how you would normally add a monster to DooM.

 

Now for the models, folder:

 

Simply drag and drop in your .md3 and your "skin" image for said model into the models folder.

 

 

 

So how do you attach the model? That's where the next text file comes in, MODELDEF.txt

 

Firstly open it up with a MODEL definition. This just tells the game "HEY I'M A MODEL!!!" After that, add a name!

Then use {} a-la scripts. Inside them define your PATH, MODEL, SKIN and SCALE definitions.

 

PATH is the name of the folder, MODEL is the model's name (EXACT NAME NEEDED OR IT WONT RENDER), SKIN is the name of the Model's texture (AGAIN, NAME NEEDED EXACTLY) and the Scale is just to scale it. (Usually I keep all 3 at the same value so it's just a simple size increase but if you want it stretched in any way, you warp it to your needs).

 

Note 1 - the "0" after the MODEL and SKIN definitions are simply the model's index number. Index always starts with 0. Typing in another set of info with 1 allows you to define 2 models into one field, however BOTH models WILL be attached together so be careful! You MUST NOT do this for two different enemies!

 

For .md3, you use FRAMEINDEX (aka frames of animation) POSS (Poss is the texture of the animation (POSS being the regular former human)) A/B/C/Whateves is the letter of animation (likw how for example a gun is like SCHG A 5) and the two numbers on the end define the model index number (so match it with the innitial number at the top and the final number is the frame from said model file.

 

Note 2 - You don't need to actually draw out a bunch of frames to fill in the gap, provided you simply have 1 sprite, you can keep using it. The DCWL at the bottom of my image below is literally just 1 sprite and I kept using it to fill in the name field. Weirdly this doesn't break GZDooM .-. .

This is what it looks like (I copy-pasta'd my stoof for my TMoD 3D project :3)

 

I might have made this a little wonky but if you need me to explain things further, just call :D

Thank you all for your help I will try to do something for my shooter

If you want to create something you could call "MY shooter", then you need to make your own engine for that. Now it would be YOUR mod or megawad for Doom.

It's not that hard. Here are some examples of 3D/PBR stuff I made including a weapon:

The biggest problem with 3D in Doom (and the reason I sort of lost interest in my 3D mod) is that there are simply too many annoying limitations. Frame indexes can quickly turn into a complicated piece of nightmare because of how many frames are needed for smooth animation. Only MD3 models can be used for animation which forces you to mess around with annoying converters and third party tools rather than being able to simply animate conventionally in your own 3D package of choice. Dynamic lights don't appear to actually work correctly for some reason, as they will sometimes make it through walls and into other nearby areas. Because 3D support is "faked" you have to make fake sprites for all your model frames. 3D models have no physics/ragdoll which can make for some weird situations in-game.

 

Simply put, while Gzdoom CAN do 3D, it doesn't do it very well. This is why I decided to dump Gzdoom for my game in favor of just simply using another engine. I wasn't planning on using any original Doom content anyway so it made no real difference anyway other than people not being able to create custom levels for it with Doom Builder, but let's be honest only tiny handful of people would probably have done so anyway so who even cares.

 

My advice is this: Don't bother with 3D in Doom. It's not worth it. There are simply too many annoying limitations and after awhile you WILL start getting tired/annoyed by them. Just stick to 2D or use another engine specifically designed for 3D.

Okay, yeah, maybe I'm exaggerating a little bit, but this is because I've never had any real experience with 3D of any kind, aside from making unholy abominations in SculptGL.

Well, perhaps "not hard" isn't the correct word. Like I mentioned above, the problem with Gzdoom's (or just any port that supports 3D stuff) 3D is that it's convoluted and plagued with all kinds of annoying limitations that constantly annoy. Gzdoom basically uses a variety of tricks to fool the engine into thinking it's actually loading sprites thus allowing for pseudo-3D support. But the problem is that this also results in a very awkward design workflow that isn't intuitive at all. It's not that it's impossible to get a decent end result, it's just that the amount of effort and tedium required to get there is so large that I don't personally think it's worth it.

I meant that I've never had any 3D experience in my life. This is beyond Doom. What I'm trying to say (which is partially unrelated to Doom itself), is that I've never had any successful attempt at making 3D models.

 

To be honest, I can't even draw a circle properly in 2D with Paint, that just goes to show how inexperienced I am.

... but you can easily Add 3D Floors with Gzdoom Builder on UDMF 

 

That is true enough for the occasional 3D floor,

but to make a map full of interconnected 3D floors and passages, the way it is done with true 3D games, is not an easy task at all. The most ambitious map for GZDoom utilizing 3D constructs that I know of is Rex's Paranoiac MAP23.

In one paragraph, you've asked for lessons for how to do something that could take many months to learn and become proficient, and could take many more months to actually produce your final product.

 

I am not trying to discourage you, but it sounds like you don't have much experience. If that's true, here's what I suggest:

 

Start out making some very small maps, using stock resources. You must learn to walk before you can run. Learn how standard maps are built. This will take some time. Once you start to get good at making maps, you can start to pursue some more advanced topics, like replacing textures, sounds, music, etc. And, after you master that, you can start to research how to build and add things like models.

 

I suggest moving slowly, and learning as you go. There's a lot to learn, and, if you try to do too much at once, it can be easy to become frustrated. Good luck!
