Another question how to write something :)

extern void printTextScreen(int x, int y, const char* text, u32 color);

How do I write the text?
I want it to show the value of this variable:

double dist;

But this doesn't work:

printTextScreen(32, 32, dist, 0xFFFFFFFF);

[pspZorba]

never used this function but from its prototype:

char buffer[42];
sprintf( buffer,"%lf", dist);
printTextScreen(32, 32, buffer, 0xFFFFFFFF);

Works great :)
But could you explain what this line does?
sprintf( buffer,"%lf", dist);

I mean, what's "%lf" ?

[pspZorba]

your printTextScreen needs a char * .

you want to print a double (dist, so you have to translate the double into a string. sprintf does the job.

sprintf needs a string ( buffer) that will contain the string, the variable you want to translate (dist) and the format => "%lf"

lt means the variable (dist) is a double.

If you wanted to transform an integer you would have set "%d".

What about float variables?

Have a read of this http://www.cplusplus.com/reference/clibrary/cstdio/sprintf.html

[WosRet]

for float use: "%f".
see this http://www.opengroup.org/onlinepubs/007908799/xsh/fprintf.html page for more information about using conversion specification
