Sorry but I just love 2D coding However although most people think it's easier to get to grips with than 3D, that isn't always the case. If you've got questions of a 2 dimensional nature then post them here. We'll take anything from "how to make sonic" to map scrolling to pixel pushing.

Cheers,

Rich

In DBPRo, can I freely intermix 2d and 3d?

i.e. could I do a tilemap based platoformer in 2d, and then overlay 3d stuff with alpha etc on top of it?

I dont see what you cant mixed 2D & 3D. In DX8, 2D sprites are really treated as a type of 3D object (I think)

Yes, I really am THAT good...

MrToad is right - there is no difference between 2D and 3D in DX8 and consequently there isn't in DBPro. You still have all the usual sprite/image/bitmap commands available to you though and they'll work just like normal 2D does - it's just behind the scenes it's actually 3D.

Cheers,

Rich

That's pretty neat. Rats, there goes all my neat 3D sprite routines... Heh, not that bothered though, gives me an excuse to rewrite large portions. Looking forward to it

Cheers

DX8 makes it quite easy to do special effects with sprites. When I was writing a 2D sprite library (years ago now), it was very easy to rotate & scale sprites, decide which part was transparent.

DBPro will make it even easier...

Does anyone know whats new in DX9 ? As I didn't take Microsoft up for beta testing it, I dont know what features it's got.

Yes, I really am THAT good...

This post isn't about 2d stones at all, the moderaters should move it at once.

Damn it Denki, it is obvious they are on about the screen display in XP rocking back and fore slightly using 2D graphics. Do you always have to come up with some Postmonesque comedy moment (minus the swearing and probably illegal pictues)?

Indi,
My screen is real..
Remember that the so called 'Real World' is made up of impressions on a retina and other sensory data.

even Pac-man has gone 3d. This high-res stuff give me a headache.

How about porting quake to 2d. A text-base quake like Champ manager.

"bang, bang"

"your dead".

if just my mind is that simple

its all 2d at the end of the day if u think about it.
3d on a comp screen is a 2d representation of a 3d environment.

Hey, there are so many more sprite commands in dbpro than db! I used to resort to texturing images onto 3d plain objects to make my 2d, but now there's sprite rotation, sprite alpha... Excuse me I'm off to do some 2d programming.

Hello Guys,
Excuse the ignorant question...
Can I do alpha blending of 2d sprites with db? or only dbpro?
Is there a sample game/demo that shows this that I can download somewhere?
Thanks!

Oh, joy, I might actually pick this up, if my collision detection in 3D problems don't cease.
Well, I suppose if it ever comes to that, I'll ask a lot of stuff. XD

I agree with what rich said in that 2D isn't always the easier option to 3D!=S I'm new to DB..okay,okay it's been on my PC for months and i've only just got back into it! Oh the shame=S

Anyway I've started playing with 2D as I thought it would be easier than 3D - wrong - I've learned how to manipulate sprites and I have a wee guy running around the screen when I move the cursor keys..anyway, getting to the point:

I'm stuck on making the background. I've heard that the background in 2D games is made up of little tiles and i followed a tutorial on making some of my own (simple grass, paving, walls etc) but I'm not sure how I actually code for these tiles, ie. how do I get them on the screen in the right places?

I've heard recently I need to look at arrays but i'm not sure what it is i'm meant to store in the array, and some people have talked about setting them out on a grid. Is this grid a physical thing (Actual code like a matrix) or is it just a term that's used?=S

Thanks, any help would be greatly appreciated=)

Have a look here at some code I posted earlier. It should give you the idea: http://www.darkbasicpro.com/apollo/view.php?t=5073&b=10

Damn it! I forgot the shameless self-plug

Here's a link to my plug-in for tiling too : http://www.matrix1.demon.co.uk/DBPro/Matrix1Map_exe01.zip

Internally, it does pretty much the same thing. If you need it to do more, I'm looking for suggestions... just email me.

The plug-in sounds great Ian but unfortunately I only have DB (v1.12 Enhanced), and not DBPro=S

I kind of understand your code above but am stuck with some bits, coudl you repost it without the scrolling? I'm not really concerned with that right now, I just want to know how to paste my tiled images onscreen in the right order to make up my scene.
If it's too much trouble you don't have to, thanks again=)

The Pixel and Vertex Shaders are wrong cause Dx9 is capable of v3.x

and there are alot more additions to the APi setup than simply a few new features like that
