For a game me and my friend are planning on starting we were going to have one big game world that the character would be free to walk around in.

My question is.... is it possible to just make a bunch of BSP zones and link them together? I would like it zone that when the player enters a specific area of a zone, the game begins to load the adjacent zone so the player can seemlessly walk from one zone into another... if that made any sense.

Few problems here.

1) DarkBASIC doesn't support BSPs, just DarkBASIC Pro.

2) BSPs take ages to load. Any time you transfer to a new area, you'd have to load a new BSP, which would make things not exactly seamless. If you're talking about pre-loading all the BSPs, it's possible, but inefficient:
a) It would be faster, smaller file size, and easier to load just 1 larger BSP.
b) Any open area of a BSP where you can walk into a void causes problems. One major one is that you can see right through the walls (since you are behind them). Tons of extra polygons will be rendered (even if you can't see them because the other BSP is blocking your vision).

Actually I ment to post this in DBPro forum... my bad.

Well then, BSPs aside, what would be the most effecient was to create a fairly large world for the player to interact with. (Or I guess another way to say this is: What would you do?)

I was wondering about this. If anyone has ever played Jak and Daxter, there are no loading times involved except at the beginning. I presumed that they didn't load the whole world at once since it is huge, I guess that they load tiny bits at a time and delete bits that are moved further away from. I wondered if this would be possible witjout significant slowdown in DB. I guess the best way is to load single objects at a time. Actually, I thik I'll try that.

Brains are for idiots.

i got some code on my site called crossover use it to link one or more matrixes together might work with bsp's too but its for DBC and download matedit it has some demo's in it where you get one huge world took me 30 minutes to run across it all at a sync rate of 0

I'm making an editor that will allow you to make whole worlds with matrices ... if I don't fail
it will be randomized matrices with my special function, but it will be faster
I'll uploade the program on a FTP when it will be finished

I won't explain how now (I don't want someone do something better than me with my system before I finish ), but you will be able to create grounds with 6553600 tiles

yeah sounds like 0.0 FPS
matrizes with 10000x10000 and 100x100 tiles (10'000) give 18-35 Frames on a P4 1,7ghz, GF4 440go, 512 MB DDR RAM ... so yours will have 0 frames if you don't give a whole engine with it to hide matrices.

*and if you think of matrix shift and dynamicaly loading ... forget about this, its even slower *gg*

The demo which UnderLord mentioned which comes with MatEdit is a 300x300 tile single matrix landscape which was made smaller to keep the size of the demo down.

In MatEdit, you can create matrix landscapes up to 600x600 tiles in size with no slowdown because the 600x600 matrix data is pumped into a scolling 10x10 tile matrix on screen in real time as you move around.

As arrays are used to hold the data and there's only ever a single small matrix on screen, you could use the same method to create a 10,000x10,000 tile matrix which would still run virtually at the same speed.

I guess the maximum size of a landscape using this method would be down to the amount of physical memory you have.

All the functions are supplied with MatEdit for setting up the matrix, as well as feeding data from the arrays when you move around, though it was written for DBC and I haven't tested it with Pro.

yeah TDK that is a awsome program except i had a problem with putting the matrixes i made in matedit into dbc it seemed to only show up as a image like i could see where everything was like the hills and such but they showed up flat like a jpg image or somthing

It's a textured, flat, plain.

As more than one of you are having the same problem, then there must be something wrong with the last released version of MatEdit.

Assuming we are all talking about the Monster Matrix Mode of MatEdit V1.6e, then I'll see if I can make a quick patch. If it's a major job, I'll fix it in the module for MatEdit Pro.

V1.6g was not an 'official' release. The only people who should have had V1.6g were those on the module writing project as it's only an empty shell and is absolutely no use for creating matrices.

Besides that, it was never finished - I abandoned it and started work on MatEdit Pro instead.

If you have it and aren't using it to create plug-in modules for MatEdit Pro, then bin it!
