width/depthwise or vertical? Vertical, no problem, it just needs a different model (the structure exists to be able to add in any number of building models, I've just only modeled one).

As for width/depth sizing, I figure I could add in a system similar to what I'm using for roads. It wouldn't be hard to do... But it'd require 6 models.

It'd be time better spent making a procedural content generator.

okay that's cool. i just rather have them look different mainly in height and maybe without making them looking like clones. i think it's possible to make more models and just randomize it. btw you have an excellent code here. do you have anymroe pics of it. like any pic of it from the road view?

I attached the file to download - it generates a random map, and you can zoom in, but sure, I'll upload some more pics

good day

I like what you did Neuro Fuzzy

I had a tiny quirk when I ran the code

Constant name 'moving' cannot share the name of a reserved word or command.
Failed to 'UnfoldFileDataConstants'

at line 121
#constant moving 2 ` ==

I changed it to

#constant zmoving 2 ` ==

I'm using dbp 7.6 and Matrix1Util and a couple of other open source addons
so it could be one of them that is tweaking things

but it dose work and quite quickly for a 2.8 dual cpu

If a thought is Just a thought ~ so whats the main thought ?

hi again

I wanted to know ware the Zombie was

so I added these 2 lines

text 0,20,"Zombie Position is "+" x ="+str$(OBJECT POSITION X(7))+" y ="+str$(OBJECT POSITION y(7))+" z ="+str$(OBJECT POSITION z(7))
text 0,40,"Camera Postion is "+" x ="+str$(CAMERA POSITION X() )+" y ="+str$(CAMERA POSITION y() )+" z ="+str$(CAMERA POSITION z() )

after text 0,0,str$(Duration)
at line 189

it seems the Zombie is way off the visible system

from what I have looked at
at this point no

but I know there is a way to save the information
that is generated so it can be loaded in to anther program

if I am not mistaken I have seen code some ware that will
let some one save an object as .x file

that will take some more thinking to make such happening
but it is possible

if you give me some time I can come up with code for saving
the generated level to be loaded into anther program

one other thing to be pointed out
if you were to save every 3d object in a single file
it would be large

I changed the size of the city to be generated from 25 to 50
so I know that would be a large file and take up a lot of memory
and time to load

so just saving the information ware I am is in the generated
world would be much much smaller and quicker to load

and if you a building or road was damaged it could be changed
on the fly unlike all the extra code needed to take the model apart

after 10 years at looking at code now I can at lest tweak thing
or even program in code to help me understand

hmm i need to do this code on my next project. if im right i can modify these models to get a variety of them.

edit: i might use this for a city for a FPS game im planning to build on. i hope my open sandbox type FPS shooter can turn out well base on my plans. oh well but im planning to use this code and later on use different kinds of buildings.
