torpor may be working on this - but he could do with an artist to create 3D models and textures, and perhaps another for sounds? While we wait for him to step in with details, here's a quick conept sketch animation showing a proposed user craft (in the middle) against a backdrop of simplistic but not-final-for-this-game 3D primitves, which I've set tumbling because I was bored.



I'm standing in for the moment, until someone faster, less distracted, and/or more skillful steps in. Does that describe YOU??

Here's the source for the current version of the "ship" model, and the texture used in the animation.

@torpor: If you need me to walk you through how the .obj file formatting works, let me know - but it should be prettty straight forward. I suspect that using actual .obj format files for the game could make it extremely easy to mod.

[B-ZaR]

This project is my new favorite thing on the forums with Pandora Pong :)

As every potential contibutor may not have played geometry wars or similar, I think it would be a good idea to recap the basic concept of the game this one will be inspired by:

Wikipedia said:

The object of Geometry Wars is to survive as long as possible and score as many points as possible by destroying an ever-increasing swarm of enemies. The game takes place on a rectangular playfield and the player controls a claw-shaped "ship" that can move in any direction using the left thumbstick, and can fire in any direction independently using the right thumbstick. The player also has a limited number of bombs that can be detonated and destroy all enemies on the playfield. As the game progresses, the player can earn extra lives and additional bombs at set score increments, and the primary weapon changes at regular intervals. Also, enemies spawn in progressively larger quantities and at greater frequency as the game progresses. If an enemy touches the player's ship, the ship explodes and a life is lost. The game is over when the player runs out of lives.

[Monk]

Thanks for that - great summary... and yeah, doesn't that Pong game sound like fun? :D

Grids? Wars? I wonder if Jeff Minter is aware of the Pandora. It's the sort of thing he used to champion. That, of course, didn't help most of those previous systems, but still...

[dentrado]

With all the talk about lowpoly wireframe glowing 3d objects I rememberd kernel panic, maybe you can use some models from that game? (I hope the spring engine get ported to the pandora btw.)

[torpor]

Okay this looks great Monk, I really like the little ship model you've done so far, thats what I was hoping you would do.

I have a surprise for you!

Some answers for questions from the other thread:

:: We don't have to use the 3D engine I propose, but it is available and it works and its quite functional already as a gridwars clone because it presents a big playfield with objects and ships racing around it already. The engine I have in my personal kit is based on Wakebreaker, a very nice little demo that you might be pleasantly surprised to discover is already working as a game engine.

You can see screenshots of WakeBreaker here:

http://pete.nextrazt...m/projects.html

Here is a port of the engine from C++ to Python/pyglet:

http://code.google.com/p/wakebreaker/

(If anyone here has a Zii Egg, I ported it to Plaszma OS: http://w1xer.de/zii/...aker/index.html )

As you can see from this screenshot, its got all the bits we need. :) Surprise, most of the work is already done, we can move rapidly into physics and modelling territory .. :) :) :)

To get the classic GW view, just change the camera.LookAt call to increase the Y of the camera from 10 to .. for example 90. Oila, instant top-down 2.5D view of the playfield, and most of the game engine is 90% done already. Heh heh!

:: Wakebreaker is a perfectly functional engine, already. It exists in C++ and Python versions. I have ported the C++ codebase to TB OS, iPhone, Zii Egg, and Beagleboard. Its a very neat little project, and I think we can definitely use it. What would be very nice is if we could use the python version of the app for the artists to work out their models, and then either port the python version (pyglet: not sure about this on Pandora) or take the models and fold them into the C++ version of the code. My preference is to use the pyglet version just for model previews but focus on modifying the C++ codebase to implement the rest of the GW stuff ..

:: Porting the existing GW code? If we get BlitzMax Basic on Pandora, sure thing .. or we can cross-port it to a new language, even python+pyglet would be nice, since its very much more accessible to newbies than a C++ project would be.

So you see, we already have a big step forward in terms of implementing our own GW clone for Pandora. I hope you guys are surprised by this! :)

This looks excellent :)

Looking forward to seeing more.

[Monk]

Jeff Minter? No idea, but if you can get him interested (and get OpenPandora interested in getting him interested) then that't be cool :)

Yeah - I like some of those. While the sphere* is already obvious, I love the Kernel Panic designs called:

Byte*
Terminal
Obelisk
Pointer
Assembler
Logic bomb
Packet
Gateway

(to varying degrees) and would encourage anyone to have a stab at bringing them to life as models suitable to this project... I have a few designs based on the graphics in Grid Wars that I want to bring to life first. Here, for example, is a new version of the player's "V" shaped craft which I've improved to make slightly more stylised and reduce the poly count further. I've taken a little more care over the UV mapping so that it would be slightly easier to paint details on the craft if one wanted a more high-tech look (though you'd need a higher resolution template for that IMHO).

Glad you like it. I have more planned but, as I think I've stated elsewhere, I'm fitting this in-between a fairly busy schedule. It's one thing to make random forum posts during the day, quite another to make even simple-looking little models (with my tools and skill set, at least). But I'll try to get a couple more done throughout the day.

Thanks to Vorporeal, BTW, for giving me a target poly count - it's helped push me to hone the V craft into something a bit better (IMHO) than the original simple extrusion. More "3D" somehow (it's not a simple rectangle from ANY direction now) and lower poly count.

[Monk]

If anyone wants to improve on the basic ball/sphere model - please do! In the meantime, here's how it looks:

As with the original V craft model, this is fairly quick and dirty and could potentially benefit from more care and attention - but it does about what I'd expect of it for now so it's "good enough" if a little high on polys.

Oops - and I forgot we were meant to be trimming down to only tris. Which will increase the poly count... I'll get back to it anon if no-one beats me to it.

OK - not unhappy with this model. Called "GreenCube" you should easily be able to identify its origins if you have the "GridWars54" game.

The design isn't 100% as I'd like it, since it has duplicate vertices where the corners meet - something I can't easily fix with the software/skills at hand without ruining the UV Mapping. the model is grouped and textured such that the texture map is very simple and represents one corner - and each corner has it's own "material". This means that it should be very easy to texture each corner identically, or differently, or indeed render only a subset of corners (perhaps one corner could vanish each time the model is hit by a laser bolt?). Each corner here is textured differently to illustrate this, even including one "transparent"/"outlined" corner.

I wouldn't mind some guidance on whether I'm being rude posting so many images/animations, or including the model definitions here, or not including copyright/copyleft/legal borrock comments all over the place.

Here's a couple more simple models - note that the textures/templates are REALLY rough - just for test purposes - ideally I'd see these being rendered as wireframe for now rather than using these templates... and I don't want to get TOO involved on textures so early if I can avoid it.

Still, here's the Pyramid...

The next 2 I want to tackle are probably going to be "PurpleCube" and "Byte" (from Kernel Panic design). Possibly a simple bullet, too.

@torpor - a couple of quick queries if I may.

1. Do I REALLY have to do without quads? They just make some models - like the sphere - look a bit neater IMHO. If I must, I must, but it'll affect upcoming designs too.

2. Can I assume we'll be able to see tris from both directions? I.E. if I have a single flat tri, all by itself, will I be able to see it, outlined or shaded, from both sides? If I can that simplifies a few model ideas I have by quite a lot (including "PurpleCub" - so I may skip that for now and move on to "Byte"). Any attempt at "pinkpinwheel" in 3D is likely to benefit tremendously from being able to see polys from both sides (or suffer tremendously - in terms of poly count and UV mapping time - from being unable to do so).

Ta,

Just to give you some feedback: as soon as I get home tonight I'll be loading this thread and taking your products to see if I can get a cheap and fast implementation within the engine, so .. keep it up and don't worry! :)

BTW, I like it that you're including template textures, for me its a bit easier to have the texture array as well .. so don't stop doing that please!

One thought - things are getting *really* 3D. :) Sure you don't want to make them a little flatter .. heh heh ..

EDIT: yes please, tris only for now. Let me get your models so far, integrated into the engine and we'll see how things start to look .. would be good if you could do a repeating-tile texture for the ground too, incidentally ..

:: Porting the existing GW code? If we get BlitzMax Basic on Pandora, sure thing .. or we can cross-port it to a new language, even python+pyglet would be nice, since its very much more accessible to newbies than a C++ project would be.

Translating the BlitzMax code looks like a nice possibility. Note however it uses OpenGL.
