Well it would be a little easier if you posted that part of the code so I could modify it for you but;

code:

var window : int                                 %Creates window variable window := Window.Open ("position:center,center") %Creates window and sets its postion (so we can close it) var ch : string (1)                              %Variable for getch loop %Begins loop     put "Enter corespoding action"               %Replace with proper instructions     getch (ch)                                   %Gets the keboard input     if ch = "x" then                             %Checks if "ch" is "x"         Window.Close (window)                    %Closes the window > Because "ch" was "x"     elsif ch = "c" then                          %Checks if its "c"         put "Welcome to control menu..."         %Replace with controls, or with a procedure     elsif ch = KEY_ENTER then                    %If its not "x" checks if you hits enter         exit when ch = KEY_ENTER                 %This exits so the game can continue     end if %ends the if statement end loop %ends the loop

EDIT - Looks very messy but just copy and paste into turing and it looks neat.

No problem. If you need any more help just send me a pm with the problem or a link to a thread with your problem : D

I don't have programming till next year and it might be canceled so I need practise

Something interesting to do is use of hasch.

It basicly checks to see if there are any letters not picked up by a get/getch as of yet in the program.

You could have a loop go off animating your menu, and as soon as a key is pressed it doesn't delay and wait for input, it already has input, and will go through and do what that character should do, then go back to animating your menu.

Also, hasch can be used for "press any key" (however, it's worth telling you that you MUST have a getch and assign that value to a variable that is... well, not worth anything except to catch that letter from falling into another "hasch trap" [hasch checks, getch gets, if it's not recived by a get, it's unread, hasch will pass, the character goes into your next getch, and passess every hasch until a getch is there {so like I said, just use getch(null) and don't use that var in the program}]).

Drakain Zeil: Or you could use Input.Flush().

What does that do?

[cycro1234]

The Input.Flush procedure empties the keyboard buffer. It is often used to avoid accidentally reading multiple keystrokes because the user pressed a key for too long, causing autorepeat.

code:

% The "Input.Flush" program. put "Press and hold a key down.  Then comment out the Input.Flush" put "and run the program a second time.  The second time the keys" put "keep echoing after the key is no longer pressed.", skip loop     if hasch then         put getchar ..         Input.Flush         delay (100)     end if end loop

Cool, I never knew about that one.

Theres always

code:

loop     locate (1, 1)     put "Press any key to exit"     exit when hasch end loop

Yes, I know about that, I even said:

My post was in refrence to the Input.Flush
