Legion Engine [PSPZones Dev]

[Sony PSP]

Hey, just stopping by to let you guys know about PSPZones Development Team's Current Project

Project Name: Legion Engine

Coders:

Shawn "Grxmx" Simonson
Jonathan "Blade" Bastnagel
Renato "Renatoc8" Ciuffo

The main goal when creating this engine was to provide developers for the PC, and homebrew developers of the PSP and Xbox a quick and easy way to start developing games their way! We realize that in order to do this we must give the developers a great architecture to build off of, one that is easy to grasp, but VERY flexible.

Legion Engine (When released) will feature an example game (First Person Shooter).

This game will introduce all features of the Engine, and with that we believe that developers can easily get an understanding of the engine, and how to use it.

While there is no ETA on the engine we hope that everyone will be pleased on its release.

Here's an old video that was recorded a few days ago. Feel free to pass it around.

Be aware that this is not how the engine will look like when release.
It's in it's early stages

Current Features -

Lighting(Ambient, Reflective, ect)
Textureing / MultiTexturing with .PNG's, and .BMP's
Easy to use Text Output.
Sound(Music / Effects)
Camera Class(Advanced Camera using Quaternions)
Entitys/Objects - All objects in the engine are derived from the Entity/Object Class
Loading .3ds models, and texturing them.

Expected Features -

ODE Implimented Physics, or PhysX(Still under decision)
.BSP loader, and .LEM(Legion Engine Map).
Bump Mapping.
Advanced frustrum culling techniques(give's huge boost in FPS).
Alot More To Be Expected!

Let me know what you guys think!

I hope the engine gets polished and published soon because having homebrew game sbased off of this technology would be nice. i wouldnt mind a wide array of nice multiplayer FPS or MMO style games. i tried getting the developers of Nezuix to get to port their engine because its based off of quake 1 but much more polished and stuff. Anyways kep up the good work and please release some kind of demo build soon.

[Psypher]

Nice start, I think it has great potential

Just add some character models, weaponry, etc. and will be nice!

[MikePiP]

Did they record that video on a Pc Version? There is an ESC key in the top left corner.

[Sony PSP]

Yes, I believe it was recorded on the computer

Holy f***! That's amazing work!

good luck with this, hope it works out well.

[Flamingwolf]

schweet, i hope somone ports CS onto this engine once its done, cuz that looks like its the ****!!!

[Sony PSP]

Im glad you guys are liking this........and in the near future we will be releasing a playable demo on my site

How soon do you guys think youll have the demo made? if you guys are setting this up with your own FPS game to contribute when do you think we will be able to start seeing some of those screenies or are you all just working on the engine in general? Another Question/Comment, If you guys are planning on using the ODE physics then try and talk to Anonymous Tipster because hes worked on porting it with good results, maybe some tweaking and it will work perfectly on the PSP. What other potential does the engine have? have you guys conidered some network code? What about other styles of games? Platformers, adventure/action titles, RPG's, anything like that in the works?

[Sony PSP]

The engine will almost never me completed......but will be added to and updated constantly untill the final relase, the good thing is that users wont have to re-complile their code each time it is updated



And also, more games will be developed as the engine itself advances......but I promise, you guys will be impresed, this could change the WHOLE face of PSP Homebrew

*BUMP*

Just so more people will see this

[Flamingwolf]

is there any way anyone can get a possible demo *wink wink* if u know what im saying *wink wink*














jkjkjk, but really, if u can let us play a demo, that wud be PIMP

[SG57]

so basically, your making a program for a PC, that will let you code much easier? Kind of like a LUA language except more easier definitons of basic statements/calls/booleans? I dunno, but good luck with .bsp injecting lol. I had a hard enough time making such a thing for Halo 2...

[Noriyuke]

Hmm well hey, since its being developed in that way, when do you think an alpha will be made avaliable to devs?

[Sony PSP]

As soon as this becomes avaliable I will release it to you guys

I'm currious to see something actualy running on a psp vs a pc. There are many hurdles to clear when doing something for the psp vs the pc. Also I am currious how you plan to do bumpmapping on the psp.

[Bladerunner627]

We'll I really don't wanna go into the details to much, but pretty much all of bumpmapping is math. All it does is move a texture under another due to certain lighting conditions, and what angle the camera is relative to the object.

Pretty much any effect can be done on the PSP, it's just the hardware limitations you have to worry about.

Right now im working on the Particle System, ill make another video today(hopefully) showing it off.

[nexis2600]

Yes but rather costly when done in software (due to the psp lacking multi texturing, thus the surface will require multiple rendering loops). So where do you plan to draw the line. I admit I am interesting in also doing a form of bump mapping in iris but still debating where the trade of will be.

[Bladerunner627]

Yea, it can be costly, but we have some tricks that will hopefully work.

[michael chan]

can you jump?i only see the screen walking around the map and crouching.

[lord pip]

valve beware.
these guys are doing your work for the psp.

Extremely costly is more like it. Pixel shaders and vertex shaders weren't invented for nothing. Software rendering would be ... horrid.

Sure but if its simple emboss bump mapping it might not be so bad. The issue at hand will come from rendering a surface 3+ times (2 for the bumpmap, 1 surface texture, + for multi textures & lightmap). Thats ungodly costly on the psp unless you have all texture work shoved into vram. Yet if you do, the textures are probably rather low res (i have issues with memory management on iris because i want to use quakes original 256x256 texturing on the maps i use).

Right now im not concerned about that area. We are concentrating on the Model Object Class right now more then anything, but yes I am clearly aware of all these issues. One thing that will help us performance wise is Frustrum Culling as well as many other types of culling. Anyways, sorry for not releasing the Particle System demo, but im still working on it.

Sorry i'm not trying to be a bother. I am just trying to offer some comments from what I have learned with my 3d engine for psp.

Best of luck to the team.

Ps, the mention of bump mapping for your engine has got me interested in adding it to my engine.

Oh, your not being a bother. Im just really not to worried about bumpmapping right now. Depending on how things work, it might not even make it's appearance in the first release.

Anyways, just so you have an Idea of where we are right now ill provide the list of coders, and what they are currently coding, and the percentage of completeness.

Me: Particle System(85 %)
Renato: GUI System(10 %)
Shawn: Object Class(95 %)

Ill keep all of you posted

Hope this isn't an UBER newb question. I don't have time to read up on the FAQ's, but what does it take inorder to be able to pos in the Developers Dungeon.

[Koba]

you need to be a developer to post in the devs dungeon. and you'll get that title when you release something you've made to the public.

Does it have to be released here? I still dont have that title and i've released 4 projects for the psp scene.
