Did you get a compiler error? What did it say? Can't find anything wrong with the code at first glance.

There is a lone "RGB (255,0,0)" after GETFONTSIZE. Is that causing the problem ?

These are the errors i am getting:

Code (glbasic) Select
precompiling:
GPC - GLBasic Precompiler V.9.829 SN:71fa70a5 - 3D, NET
"Ditrabox.gbas"(9) warning : probably unassigned variable : varnombre$
"Ditrabox.gbas"(20) warning : probably unassigned variable : x$
"Ditrabox.gbas"(9) error : variable is not explicitly defined : varnombre$

All this means is that the variables have not been defined before use. You can either declare them explicitly (Good move) or go into Project>Options and set the tick box for Explicity Declarations too off (Bad move)

Yep set either LOCAL varnombre$, x$ or GLOBAL varnombre$, x$ before referencing the variables ;)

It would be handy if GLBasic included an error (or warning) number/id with each error.
You could use this to search the forums to find possible solutions, or to better understand the error.

And/or have the error include an optional link to a help file listing about the error and what are common causes, or link to a web page with that info.

Eg:
Code (glbasic) Select
"Ditrabox.gbas"(9) error [#12345] : variable is not explicitly defined : varnombre$

for a faster test, i disabled explicit variables, but at compiling it says:

it does display an error... maybe there´s a problem with the directory where the project is located?

Your problems are these lines:
Code (glbasic) Select
GETFONTSIZE 30,30
// and
GETFONTSIZE 28,28

The'GETFONTSIZE()' command expects two integer variables, and you're providing constants.
The command is for retrieving the current font size, you can't pass it numerical constants.
This is how you use it:
Code (glbasic) Select
LOCAL size_x%, size_y%
GETFONTSIZE size_x, size_y
DEBUG "The current font size is: " + size_x + " x " + size_y + "\n"

Slydog... YOU´RE MY HERO!!

i deleted the GETFONTSIZE since i though they would change the font size...

now i can compile and my project seems to be working now...

looks like its more complicated than i though but maybe in about a month i can create an interesting game :D
