Timed Target Cursor

I tried using the TargetEX(who, time); functions and although they work I have some problems.

It is really easy to get a "nnnn used out-of-sequence target cursor" console error if you double click a target.

Also the function itself seems to be buggy: the second half after the return statment can't run can it?

Code:

function TargetEX(mobile, duration:=0, flags := TGTOPT_CHECK_LOS+TGTOPT_NEUTRAL)
   if ( duration > 0 )
      if ( CInt(TS_GetTimerDuration(mobile, "TargetControl")) > 0 )
         // Existing timer... stop it (itll cancel the old target)
         TS_LowerDuration(mobile, "TargetControl", -1);
      endif

      TS_StartTimer(mobile, "TargetControl", duration);
   endif

   return Target(mobile, flags);

   if ( duration > 0 )
      if ( CInt(TS_GetTimerDuration(mobile, "TargetControl")) > 0 )
         TS_LowerDuration(mobile, "TargetControl", -1);
      endif
   endif

   return 1;
endfunction

It also appears the program is killed when the timer runs down. Any reason for this? Wouldn't it just be better for the target cursor to cancel and the TargetEX return 0 if it timed out?

Fixed by MuadDib in record time.
Fix available in distro SVN now.

Many thanks.

NP. Please be sure to do extensive testing and report back in irc or here

Yep, I am about to subject my staff to a square meal of TargetEX. This will soon weed out any problems.

As a matter of interest, the way MaudDib explained it, these functions are set up in such a way that it is important to test the function return for errors to avoid the "nnnn used out-of-sequence target cursor" errors. For example:

Code:

var targetted := TargetEX(who, 10);
if ( !targetted or targetted.errortext )
  return 0;
endif

Both TargetEX and TargetCoordinatesEX will now return an error if there is already a target cursor being displayed.
