Need Help with Shopping Program (GUI Interface)

Hi

Am having trouble getting this program to work, I am in grade 9 and it is my first attempt to use turing

This is a pretty good start for first time using Turing.

It looks like the program just gets stuck in this loop

Turing:

%starts mouse locator loop loop     mousewhere (xmouse, ymouse, button)     if button = 1 and 200 <= xmouse and xmouse <= 260 and 300 <= ymouse and ymouse <= 320 then         cls         drawfillbox (0, 0, maxx, maxy, red)         %draws clickable box on to the screen         locatexy (1, 350)         put "this is the price of our stratacaster guitars, click on it to buy it"         drawbox (200, 300, 260, 320, black)         locatexy (210, 310)         put "stratocaster - $1300"     end if end loop

There is no exit, it will just loop forever, checking for a button press, even though you have already drawn the next screen/page. Buttons and pages are known to be difficult to setup correctly. You have the right ideas, just have to be careful about figuring out just exactly in which loop the code is running.

thanks for the help, I really appreciate it

I'm not sure where to put the exit, I tried and exit right after the end if, but no luck

What does an exit statement look like?

Turing's documentation -- exit

Keep in mind that when a loop exits, the code flow jumps to the "end loop" point and continues from there, _but_ the old page will still be drawn on the screen until the code gets to the drawing part.

Sorry I still can't figure out what the exit statement needs to look like. My parents are trying to help me with this and they can't either. Do you have any more suggestions

[Tony]

It will probably look something like

Turing:

if button = 1 and ... % same way you do all other buttons     exit end if

Thank you. You have been a big help.
Happy New Year!

could also go like

code:

exit when var = this
