Hi, im using darkbasic pro, how would i add a building/cube/rectangle sitting ontop of the created matrix? im confused with it.

here's my code:

+ Code Snippet

sync on
sync rate 0
hide mouse
make matrix 1,1024,1024,16,16
load image "ground.jpg",1
prepare matrix texture 1,1,1,1

color backdrop 0

xrotate camera 40

speed=5
camerax#=512
cameraz#=512

do
if mousex()>screen width()-10 then inc camerax#,speed
 if mousex()<10 then dec camerax#,scrollspeed
if mousey()<10 then inc cameraz#,scrollspeed
if mousey()>screen height()-10 then dec cameraz#,speed

position camera camerax#,400,cameraz#

sync
loop

attached is ground.jph(from the tutorials)

ok so i guess adding a 'cube' was easy.

here's my code now

+ Code Snippet

sync on
sync rate 0
hide mouse
make matrix 1,1024,1024,16,16
position matrix 1,-512,0,-512
load image "ground.jpg",1
prepare matrix texture 1,1,1,1
make object box 1,4,3,10
make object cube 2,100

color object 1,rgb(255,0,0)
color object 2,rgb(0,255,0)



color backdrop 0

xrotate camera 40

speed=5
camerax#=512
cameraz#=512

do
if mousex()>screen width()-10 then inc camerax#,speed
 if mousex()<10 then dec camerax#,speed
if mousey()<10 then inc cameraz#,speed
if mousey()>screen height()-10 then dec cameraz#,speed

if upkey()=1
move object 1,2
endif
if downkey()=1
move object 1,-2
endif
if rightkey()=1
Turn Object Right 1,2
endif
if leftkey()=1
Turn Object Left 1,2
endif


position camera camerax#,400,cameraz#
text 1,1,"Screen fps: "+str$(screen fps())
sync
loop

My second question is, How do u check collision against the cube and the box(arrow keys to move the tiny block, also, when u start it up, drag your mouse bottom-left a little to see the matrix).

i'd do it something like this:

+ Code Snippet

sync on
sync rate 0
hide mouse
make matrix 1,1024,1024,16,16
load image "ground.jpg",1
prepare matrix texture 1,1,1,1

color backdrop 0

xrotate camera 40

`the cube...
make object cube 1,50
position object 1,600,25,600


speed=5
camerax#=512
cameraz#=512

do
if mousex()>screen width()-10 then inc camerax#,speed
 if mousex()<10 then dec camerax#,scrollspeed
if mousey()<10 then inc cameraz#,scrollspeed
if mousey()>screen height()-10 then dec cameraz#,speed

position camera camerax#,400,cameraz#

sync
loop

by the way you do know that your mouse movement only works right and down at the moment don't you?

the cube isn't in the place where you see it when you start off it's just at a random point on the matrix but you'll see it if you move the mouse down...

and it's at height 25 because DB registers the height from the center of the object and the cube i drew is 50 units tall and half of 50 is 25 so the center is in the right place so it appears to be sitting on the ground

to load an object in you would have to use

+ Code Snippet

load object "filename",number

don't forget the extension and make sure if it is in a different folder you include the complete path to it

you may also have to scale the object if you load it

thats about all i can think of to write so i hope that's helped...

Have a look at GET GROUND HEIGHT. Here's your code with this put in. Like demon said, DB draws cubes with the center point or origin of the cube being in the middle. So, here is your changed code with the cube thing added.

+ Code Snippet

sync on
sync rate 0
hide mouse
make matrix 1,1024,1024,16,16
load image "ground.jpg",1
prepare matrix texture 1,1,1,1

`Make a tall building.
Make Object box 1,25,100,25
`Put it in the middle of the matrix.
Position object 1,512,Get Ground height(1,512,512)+50,512
color backdrop 0

xrotate camera 40

speed=5
camerax#=512
cameraz#=512

do
if mousex()>screen width()-10 then inc camerax#,speed
 if mousex()<10 then dec camerax#,scrollspeed
if mousey()<10 then inc cameraz#,scrollspeed
if mousey()>screen height()-10 then dec cameraz#,speed

position camera camerax#,400,cameraz#

sync
loop

yeh, i fixed it awhile ago, just accidently wrote "scrollspeed" instead of "speed".

ok so a third question, how to detect collision between a .x obj with the camera?

You can find the .x object from 3D world studio folder(examples)

My fourth question is, how do you texture the .x object?
