Hi all, I have been a reader of these forums for a little while, now I have the need to post. Sorry, this is quite a simple task, but I can't seem to get it right.

I have created a matrix and I want to use it as a (scrolling) background for a 2d sidescrolling game. Currently, it is 6400 tiles wide x 128 tiles high, broken up into 64x64 squares. Could somebody please show me a simple code snippet where the matrix is shown on the screen completely flat? It would be greatly appreciated.

I think I just need the co-ordinates to position the matrix, and the co-ordinates for the camera's position and where it is pointing.

I'll include the basic code I have so far.

+ Code Snippet

` initialisation
sync on
hide mouse
set display mode 1024,768,16
load bitmap "tilebitmaptest.bmp",1
get image 1,0,0,640,640
delete bitmap 1

make matrix 1,6400,128,64,64
prepare matrix texture 1,1,10,10
fill matrix 1,0,6


for x=1 to 10
   for z=1 to 10
      read tile#
      set matrix tile 1,x,z,tile#
   next z
next x



` Main game

sync

It's ok, I've got it sussed. Now I have the basic structure down, I can just add and improve tiles to make it look better.

` initialisation
sync on
hide mouse
set display mode 1024,768,16
load bitmap "tilebitmap.bmp",1
get image 1,0,0,640,640
delete bitmap 1

make matrix 1,640,128,100,20
prepare matrix texture 1,1,10,10
fill matrix 1,0,6

restore levelone
for z=0 to 19
   for x=0 to 31
      read tile
      set matrix tile 1,x,z,tile
   next x
next z
update matrix 1

do
position camera 97,120,64
point camera 97,0,64
wait 1000
for j=98 to 640
   wait 1
   position camera j,120,64
   point camera j,0,64
next j
sync
loop
