I want to programm a 2D tile game.
i have startet with the game field.
whole game field is 20x20 tiles

each tile 40x40 pixel width

i use the following code for output:

+ Code Snippet

while mouseclick() 2

for x=0 to 19
for y=0 to 19
  paste image 300, x*40, y*40
next y
next x

sync

endwhile

but it seems to be terrible slow and i only have a plain field of tiles. later it should be read out of a array which tile to be used. i dont know how to optimize. could anybody give me a hint.

i ve also startet a thread asking how to calculate ftp since i dont know the real ftp rate. i only saw that the mouse cursor moved very slow and ugly.

please help me i am very new to programming dark basic. maybe i do something wrong.

Nice idea, that tile system. I used that once too (when I still worked with Div)
I think you mean fps, instead of ftp, so the command for that is this:
screen fps()
paste something like this in your main loop
print screen fps()
that will give you the refresh rate (frames per second)
You can try to make a plain object of that size and then make a bitmap.

+ Code Snippet

make object plain 1, 800,800

create bitmap 1,800,800
set current bitmap 1

Rem load the bitmaps and stuff here

For X = 0 to 19
   For Y = 0 to 19
      paste image ImageNumber,X * 40, Y * 40
   Next Y
Next X

texture object 1, 1

Rem main loop and other things

hope this will help.

O yes, forgot to ask you: are you working in DBC or DBPro, for I have noticed DBC isn't that good in 2D.
That's why I also advice you to make a plain object and texture that. By the way. I haven't tested my snippet, so I hope it works
