I played around with 3D rendering a bit.
This could be implemented as an option in CS2D.

Perfect, except for side of big crate, wrong textures.

Now go back to past, in year of 2012 and add this thing to 1.1.8 version.

Looks good, works very bugged, if you can fix the bugs then its good

players looks like a hobbit really, But i'll love to play with this.

With buggy i meant that guy on 0:26 trasspasing the walls.

Maybe you can easily add this as a new form of tile just like "obstacle with shadow" or not
an option to mark it as "3D"
i mean like that you can add it for sure without even asking.

But as default could work too, depends on the demo

Another thing that i wonder is it's relation with the already made maps that are complex, pretending to have stairs -roofs etc

wow this is ground breaking, im really hyped about this.

I'd like to see the maps icc_cbble, sf_mirage

@ SQ: nice one how about this 3d buy menu?

Rather to fix all the bugs and add some colour effects if you found some time to do the game. Since there is many questions and suggestions about 3d you should have think about manyshit:

It would be possible to make nice 3d stairs like andrez said and make 3D ladders(also!) which placed on walls? Or atleast just image which is not looks like flat but like on wall?
So it could be like:
image("path<3d>",x,y,r,m), etc.
If we place images they won't looks shitty bcs of walls?
They whould have options for their size?
C4's alarm through walls?
and very fckin' more. Just have no time..

Now edit the players and take out a new version

This is a good graphics update, but however, it should be a per-map setting because many maps were made with the flat 2D graphics in mind. Their tilesets reflect that, with graphics techniques to create the illusion of multiple floors for example.

This also changes the gameplay because the player needs to adapt to the different rendering and how the map appears in their screen. In flat 2D we can always easily pinpoint our shoots through multiple tiles, in 3D that's not really possible because the walls and obstacles appear "tilted", if you get what I mean.

So, here is how you should proceed with this:

1) Make it a per-map setting, so both 2D and 3D maps can co-exist. This avoids breaking and ruining previously created maps.

2) On each 3D tile, make it possible to set their height (seems like you already did this, as shown in the video) and if possible a different texture for their sides. If no separate texture is provided for their sides, then the top texture will be used and thus scaled according to the 3D tile's height.

3) For 3D maps, make it possible to create multiple floors and map them separately, this also makes 3D stairs easy to make. That if it's feasible, because it requires extra coding and you probably don't want to do that. It would be a killer feature though and would completely change the map making landscape.

But well, I think you should focus on more important issues first. This graphics update can come in another game version.

@ BCG2000: This is what I'm thinking of as well. It also very buggy feature. So leaving it separate map option is a good idea, so make maker would decide how to solve some issues while doing the map.

I love this!
Is this going to be an official feature?

Damn, that looks absolutely awesome! Would love to see this in the next update.

Let's go back in time(At that time it was just parallax - 2,5D):
21.01.16 14:50:27

06.12.16 23:33:38

Anyway i like 3D in this version - Thank you SQ!!!

Since players are flat they not fit anymore.

Do you remember GTA2?

@ SQ: He's not old enough to remember.

Are you mean these:
GTA 1

GTA 2

GTA 3

GTA 4

GTA 5

?

Yates: ye, i just keep that in mind all the time I played it on sega dreamcast. Then on pc.
SQ, yes.. but it doesn't looks good. Also the camera distance is different far.

Wow i agree 100%

I like the multiple tile layers idea to make multiple floor levels. But it would introduce many problems that are not considered in a 2D game.
