Disabling certain sections of the screen

[tristanbryce7]

I am trying to make it so that, i have four boxes (using drawbox) on the screen, and only one box is correct, so if the user clicks a wrong box (mousewhere), it draws a "wrong" picture, and also blacks out the box (drawfillbox). Now i want it so that if they click the same box again, nothing happens, how would I do that?

how are you making it do "not nothing" (show code)?

The typical approach is

code:

if (conditions_to_do_something) and (has_not_done_this_before) then    % do something end if

Well, I am using mousewhere inside a loop, so if they click it again it would execute again

its basically a quiz, and they have 4 options, and each box is an option, so if they don't click the right one, i want to just "disable" that set of co-ordinates so if they click there again (no matter how many times they do, (excluding the first time, in which it says "Wrong" and draws a Pic of a big X) the program doesnt do anything

Turing:

loop     mousewhere (x, y, b)     if b = 1 and x >= 48 and x <= 202 and y >= 505 and y <= 650 then         Pic.Draw (picWrong, 50, 150, picCopy)     elsif b = 1 and x >= 41 and x <= 233 and y >= 274 and y <= 441 then         Pic.Draw (picWrong, 50, 190, picCopy)         %Third Option     elsif b = 1 and x >= 28 and x <= 239 and y >= 4 and y <= 207 then         Pic.Draw (picWrong, 50, 210, picCopy)     elsif b = 1 and x >= 1054 and x <= maxx and y >= 758 and y <= maxy then         Pic.Draw (picCorrect, 50, 240, picCopy)         exit     end if end loop

so say that they click on the third option, and it turns out to be wrong, i want it it so that they remain in the loop, but now that statement which says

Turing:

elsif b = 1 and x >= 28 and x <= 239 and y >= 4 and y <= 207 then

is unactive. I was thinking of somehow being able to make it false using booleans, b/c my friend said I should try that, but I don;t know how to make a bunch of co-ordinates "false"

[Tony]

code:

... and option_three_active then Pic.Draw (picWrong, 50, 210, picCopy) ...

where option_three_active is your boolean variable with the appropriate value set.

[tristanbryce7]

So then should i also
make option_three active false afterwards?
like
.. and option_three_active then
Pic.Draw (picWrong, 50, 210, picCopy)
option_three_active := false ... ?

[Tony]

exactly!

Thanks man!!
