Jason,

I would also like to point out that you don't need to do a double loop for creating your level this should work fine;

+ Code Snippet

	   For x=1 to Mapsize
			For z=1 to Mapsize
				If Map$(z,x)="#"
					Make Object Cube MapObjectNumber,32
					Position Object MapObjectNumber,x*32,0,z*32
					Texture Object MapObjectNumber,1
					MapObjectNumber=MapObjectNumber+1
				endif
				If Map$(z,x)="."
					Make Object Plain MapObjectNumber,32,32
					Position Object MapObjectNumber,x*32,0,z*32
					Texture Object MapObjectNumber,2
					MapObjectNumber=MapObjectNumber+1
				endif
			next z
		Next x
		levelCreated=1

Now, as for why you're getting these results it's because of your READ MAP code... you have the X & Y values switched around.

+ Code Snippet

Function LoadMap(Filename$,Size)
	Open to read 1,Filename$
	For x=1 to Size
	For y=1 to Size
		Read Byte 1,tmp
		map$(x,y)=chr$(tmp)
	next y
	next x
	Close File 1
Endfunction

In other words -- when READ the map, you're reading it Left-to-Right then Top-to-Bottom, but when you build the image you're building it Top-to-Bottom then Left-To-Right. You're reading code and your building code must match...

In Read, the value it map(x,Y) -- with Y changing first, then X
In Build its map(z,x) -- with Z changing first!

oops.

S.

Any truly great code should be indisguishable from magic.

sure ... change;

+ Code Snippet

Function LoadMap(Filename$,Size)
	Open to read 1,Filename$
	For x=1 to Size
	For y=1 to Size
		Read Byte 1,tmp
		map$(x,y)=chr$(tmp)
	next y
	next x
	Close File 1
Endfunction

TO;

+ Code Snippet

Function LoadMap(Filename$,Size)
	Open to read 1,Filename$
	For x=1 to Size
	For y=1 to Size
		Read Byte 1,tmp
		map$(y,x)=chr$(tmp)
	next y
	next x
	Close File 1
Endfunction

Leave the rest as you posted it...
S.

(Look close -- there IS a change in there!)

Oh! Of course... makes sense now...

You are saving your level file as a TEXT one.. meaning you have two characters at the end of each line. (That's a CR/LF)

The read MUST be changed to reflect this, as in;

+ Code Snippet

Function LoadMap(Filename$,Size)
	Open to read 1,Filename$
	For x=1 to Size
	For y=1 to Size
		Read Byte 1,tmp
		map$(x,y)=chr$(tmp)
	next y
        read byte 1, a
        read byte 1, b
	next x
	Close File 1
Endfunction

You were still reading it wrong in the x/y direction, but the above should solve your troubles...
