make object box 900,50,50,50
set object collision on 900
`hide object 900
position object 900,2689,0,2409
x# = object position x(900)
z# = object position z(900)
y# = get ground height(1,x#,z#)

do
x#=newxvalue(x#,a#,s#)
z#=newzvalue(z#,a#,s#)
y#=get ground height(1,x#,z#)
position object 900,x#,y#+5,z#
yrotate object 900,a#
if upkey()=1 and s#<12 then s#=s#+2
if downkey()=1 and s#>-12 then s#=s#-2
if leftkey()=1 then a#=wrapvalue(a#-4)
if rightkey()=1 then a#=wrapvalue(a#+4)
gosub update_camera
sync
loop
update_camera:
rem Position camera to the back of the character
cx#=newxvalue(x#,wrapvalue(a#),-300)
cz#=newzvalue(z#,wrapvalue(a#),-300)
cy#=get ground height(1,x#,z#)
position camera cx#,cy#+25,cz#
rem Point camera at object
point camera x#,y#,z#
return

Your object is moves fine. It moves in the direction that it is facing in.
Your problem is that your camera is positioned to the left of your object.

Change:
cameraz# = newzvalue(z#,AngleY#-100,100)
camerax# = newxvalue(x#,AngleY#-100,100)

To:
cameraz# = newzvalue(z#,AngleY#-180,100)
camerax# = newxvalue(x#,AngleY#-180,100)

This will position the camera behind your object.

yeah, i just now found my mistake about the 180 degree thing. i want the camera to follow the object closer, i tried the set camera to follow command but the camera would just go straight through the matrix when following the object. going to try scorpyio's code to see how that works.

that code goes straight through the matrix also.

Use the code that i pasted in "Moving over a landscape".
It works. I've tested it. It doesn't go through the matrix.
Just change the "Load image "twigs02.bmp",1" to what ever texture you have in the same directory as the code.

Or better yet go to [href]www.darkbasic.com[/href]. Then click on the create tab at the top. Then find the online 3d tutorials and start reading.

To get the camera closer:

cameraz# = newzvalue(z#,AngleY#-180,100)
camerax# = newxvalue(x#,AngleY#-180,100)

Make the bold number smaller to bring camera in towards object.

If your going to have the camera right on top of the object do you want to see the object??? If not then you don't really need the object at all. Just move the camera around with the arrow keys.

Ex.
Do

cYang# = camera angle y()

If upkey()=1 then move camera 5
If downkey()=1 then move camera -5
If leftkey()=1 then yrotate camera wrapvalue(cYang#-5)
If rightkey()=1 then yrotate camera wrapvalue(cYang#+5)

Loop

i need the object for collision, i tried making those values smaller but it kept making the camera look down on the object instead of ahead.

Is there a POINT CAMERA x,y,z command in your code???
I bet there is.

Try increasing the "y" value in that command.
