I think it is most probably very hard, because in 2D the concept of camera doesn't exist, which mean calculating the view inside an opened portal will be a real pain in the ass.

In 3D, you just have to put cameras in the portals and replace the pixels inside the portal with those given by the camera. It's already pretty hard to optimize properly.

In "Doom style", calculating the view inside the portal would require very complex math. The kind of complex math that is necessary to code a graphic engine, which is the hardest part to code in a game.

Don't want to ruin your hopes, but I don't think a one man team can do such a thing. Unless you're some kind of super math expert.

And besides, why would we play that, when we can just create more beautiful and effective and custom maps for the original game?
To me your project looks like a pure waste of time and effort, unless I didn't understand what your objective is.

umm... eh??

What are you guys talking about?

I've already made on room.

I'm heading off to eat lunch, I'll share it later.
I'm not really done yet with it.

And i'm still trying to find ways to "bump the portals" and make them Straight.

EDIT:

Not completely done, I havn't made some walls unportable.

You might want to check how it "kind of" works by giving your self an upgraded portal gun.

Well, its not what I expected. You basically made a portal map that is very skinny with black for the side walls. It still has 100% 3d models in it, which I'm not saying is a bad thing, but its not what I think of as 2.5D.

The only way I can see this as being fun is if it were just like Flash Portal, where you have the camera viewing the entire map from a distance from the side. Then you make the geometry of the map slightly tilted so that all the walls, ceilings, and floors are viewable from that one side perspective. Of coarse the controls would have to be different...I'm not sure if all that is possible, but if so its not really worth it in my opinion.

Edit:
I hate to give such feedback, but I just don't see much potential here.

On the other hand you could possibly make a normal 3D portal map with some narrow hallways that incorporate some of the play mechanics of Flash Portal. That could be a good thing.

I don't plan anything like that.
I like this style... in a way.

Though placing portals is a little more difficult, this only contains 10 short chambers.

THEN, I might consider making something you expected this to be.

Which is Flash Portal, with 3d textures.

Because If I implament the side view camera now, you won't be able to see the portals on the side walls, and making the walls slanded would "ruin" the portal's transport. Also, You need new controls xP

Anyway, I'm interested to see what you come up with for your current project, Atlantisrobo.

Ok, I tried it.

This is absolutely not 2.5D! No wonder no one understood before you put a demo.

2.5D refers to 2D with several planes, not 3D where you can only move in 2D. Super mario world had 2.5 D sequences with grids where you could be "in front" or "behind".
Same thing in the first level of Castlevania 4.

Sometimes games like Doom display 3D graphics but are in fact 2.5 D for the engine : an entity is defined in space by x, y and "current floor".
Instead of X,Y, Z in regular 3D.

Your demo reminds me much more of crash bandicoot can than mario bros DS. Crash Bandicoot kind of games are generally referred to "precalculated 3D" rather than 2.5D.

I don't want to be mean, but I don't see much interest in your idea : 2D portal is available to everyone with the flash version, and guys who bought regular portal want 3D and freedom to experiment in space.

IMO, upgrading the graphics of the flash version with 3D (or even "fake 3D" you would render before the game executes, donkey kong country style) is the best way to achieve what you originally meant with "2.5D like super mario bros". Even if in technician terms, it is NOT 2.5D.

What youme explained, which is "making a 2D game with a 3D engine by cheating the camera" is also good.

actually when i FIRST read this guys post i had no idea wtf he was talking about. man go back and edit that. but. now. after having PLAYED his "first" room. i see LOTS of potential here (atleast for those of us that have played portal-flash)

its like this. You remember playing mario on the orriginal NES? it was 100% 2d, and a side scroller (much like portal-flash) (or any other old 100%2d side scroller, some of you may be to young to have any idea wtf i'm talking about) now. i don't know about ya'll, but i used to always wonder how cool it would be to JUMP-INTO the game, and look through marios eyes and play the levels.. well of coarse i wouldn't be able to traverse towards or away from the "player" cuz then that would be 3d, but i would still be able to go along the same paths. and everything (to me) would look 3d and such, and that is what THIS project reminds me of. like replaying the flash levels but with a First-person perspective.

if you work real hard on this and set it up proper. i think it would be really cool. but in order to sell it you have to make sure people play the flash version first. so really advertise that stuff. find the most reliable link to the flash version and SELL SELL SELL it to the player that they should play it first :-p

edit: after re-reading this i think i should clarify, by "sell" i mean make the person see your idea/perspective/point-of-view on the idea of this, not actually make money, slang ftw!
