Timer game delphi 7

[Iña 0]

I making a game of who writes the word faster, store it in an array, and then show in a memo.

 

my problem is when the minutes>0 the seconds are still running(the seconds doesn´t start at 0 again), so  the only thing i need is when t is 60000(60 seconds) it should start at 0 again(the seconds)

 

procedure TForm1.Button1Click(Sender: TObject);
    type
    people=array[1..2] of string;
    peopletime=array[1..2] of integer;
    var
    string1,text:string;
    time:integer;
    k,seconds:integer;
    p:people;
    p1:peopletime;
    t,minutes:cardinal;
    begin
    memo1.Lines.Clear;
    k:=1;
    p[1]:='James';
    p[2]:='Dan';
    repeat
     t:=gettickcount;
     timer1.Enabled:=true;
     
     if text='day' then
       begin
       t:=gettickcount-t;
       seconds:=t div 1000;
       minutes:=t div 60000;
       form1.Memo1.Lines.add(p[k]+' '+inttostr(minutes)+' '+'minutes'+' 
       '+inttostr(seconds));
       k:=k+1;
       timer1.Enabled:=false;
       end;

    until k=3;
    end;

(i don' t know if this the proper way to use timer, i don't know much about timers)

Use TStopWatch from System.Diagnostics / System.TimeSpan.

How i do that? I'm a newbie with timers

I'm afraid System.Diagnostics was not part of Delphi 7.

[Lars Fosdal 1792]

A VCL:TTimer / FMX:TTimer is something that produces an event after a given interval, so not what you are looking for when you want to measure an interval.

A TStopWatch is handy for measuring an interval.

A TTimeSpan is an interval and has numerous methods for converting to various time units

var
  t: TStopWatch;
  time: TTimeSpan;

whenever you want to start measuring

  t := TStopWatch.StartNew;

When you want to measure 

time := t.Elapsed;

Alternatively

  t.Stop;
  time := t.Elapsed;

Have a look at the TTimeSpan doc for how to get the various time units.

 

Your Button1Click does not solve your problem since nothing else can happen while you are inside that code.

 

Sometimes it helps to clarify how to solve a problem by writing the solution in regular text.

 

That is as far as I will go in solving homework assignments.

Ah, yeah... that is true.  My explanation of TTimer events vs measuring an interval still stands.

I forgot to paste this

Text:=inputbox('enter the word','',''); it goes above the if

You're here calculating the total seconds and minutes. Try:

seconds:=t div 1000;

minutes:=seconds div 60;

seconds:=seconds-(minutes*60);

Thx @Lajos Juhász [solved]

This would be easier:

seconds:=seconds mod 60;

Please find attached unit StopWatch for Delphi 7 (StopWatch.pas)

This is from Zarko Gajic, possibly not exactly identical to that  from System.Diagnostics.
