Screen 5 tutorials

have you checked the genic/sunrise magazines, especially the 'specials' ? you'll find some very interesting stuff there (hell, even some articles from me )
good luck
(you'll find the magz. on funet. see the linx->FTP section here)

Is there any MSX-Basic editor available that can handle multiple bas files in different windows, so I could copy-paste stuff ?
No, but you could save as ASCII (SAVE "file",A) and load it up in a text editor.

Alternatively, if you're gonna use text editors anyway, you could use use Nestorpreter. (www.konamiman.com)
It allows you to use long variable names, no more linenumbers but actual labels (like MS Q-BASIC) etc.. It makes BASIC programming a lot easier/nicer!

Ok, I've been meaning to check out the Nestor tools, just hadn't had the time
Still coding on my 3D OpenGL game based on MoG Still lots and lots of work to do there

Maybe later today I'll check it all out
Thanks for your replies.

I want to learn how to store graphics tiles, and then loading them to the screen to build up a game level.

I want to learn how to store graphics tiles, and then loading them to the screen to build up a game level.

For 8x8 tiles, it would be something like this:

10 screen 5
20 set page 0,1
30 rem Load tiles in page 1
40 bload"Titles",s
50 rem Load level data, say at &hC000
50 bload"level.dat"
60 a=&hc000
70 for y=0 to 184 step 8
80 for x=0 to 248 step 8
90 rem get tile number
100 t=peek(a):a=a+1
110 rem evaluate position X/Y of tile according to its number (max 256 tiles)
120 ty=t32:tx=t and 31
130 rem Copy the correct tile from page 1 to page 0
140 copy(tx,ty)-(tx+7,ty+7),1 to (x,y),0
150 next x
160 next y
170 goto 170

It 's gonna take you 768 (32x24) bytes to store the level data.

Quiet simplified but you got the idea.
