I've try this

int mouseX,mouseY;
mouseX = bbMouseX();
mouseY = bbMouseY();
bbText (0,0,mouseX);
bbText (0,20,mouseY);

it did not work because bbText, bbPrint, bbWrite accept only text parameter. anyone coule help? thank you.

Try converting it over to a string then first. What language are you using?

I am not using C but in EBasic or PowerBasic I'd use:

bbText(0,0,str$(mouseX))
bbText(0,20,str$(mouseY))

or:

bbText(0,0,"MX: "+str$(mouseX)+" MY: "+str$(mouseY))

str$ translates a number into a string. I am sure you can use a C equivalent.

ar... I've finished it up with something like this

int mouseX,mouseY;
char buff[10] ;

mouseX = bbMouseX();
mouseY = bbMouseY();

bbText(0,20,"Mouse X:");
bbText(100,20,itoa(mouseX,buff,10));

bbText(0,40,"Mouse Y:");
bbText(100,40,itoa(mouseY,buff,10));

however, I cannot combine text and converted text into one command. thank you guys,

MeowZ you can combine text and converted text with the C function:- sprintf()

useage: sprintf( buff, "%s %d", "Mouse X:",mouseX);

Check your C documentation for details :)

Cheers,

Roy

Hi Roy,

We cannot use ?printf() to print text on Blitz3d. - -a
in B3D window, must use bbText.

thank you,

Hi MeowZ,

sprintf() is a C string formatting function - it does'nt print anything!
If MouseX=100 then the output for my above example would store the formatted text "Mouse X: 100" in the buffer you declared as char buff[10] though you would have to increase the size of that buffer to something larger.
You would then print the text using bbText(0,20,buff)

Cheers,

Roy
