Waiting for a color/bitmap to appear with a timeout

Recommended Posts

Using WaitTrue and WaitFalse functions you can wait for any function to return True or False with a timeout.

 

For example, I have a function called Attack that simply clicks the monster and another called HasTarget that checks if any creature is targeted and returns True or False. I want to have a safe bot that understands possible mistakes and fixes them. Let's implement it:

Attack(creatureX, creatureY);
if WaitTrue(@HasTarget, 2000) then
begin
 WriteLn('Creature successfully targeted. Now waiting for it to die.');
 if WaitFalse(@HasTarget, 30000) then
 begin
   WriteLn('Success. Target disappeared (died), looting it.');
   // TODO: Looter.
 else
 begin
   WriteLn('Timeout. 30 seconds past and the target is still alive. Re-attacking it.');
   // TODO: Re-attack.
 end;
else
begin
 WriteLn('Timeout. 2 seconds past and nothing is targeted yet, trying another creature');
 // TODO: Try to attack another creature...
end;[/scar]

If anyone is interested, this is the needed block of code to have WaitTrue and WaitFalse:
[scar]type
 Void = function: Boolean;

function WaitFunc(func: Void; positive: Boolean; timeout: Integer): Boolean;
var start: Integer;
begin
 start := GetSystemTime;
 Result := True;
 while func() <> positive do
 begin
   if GetSystemTime - start >= timeout then
   begin
     Result := False;
     break;
   end;
 end;
end;

function WaitTrue(func: Void; timeout: Integer): Boolean;
begin
 Result := WaitFunc(func, True, timeout);
end;

function WaitFalse(func: Void; timeout: Integer): Boolean;
begin
 Result := WaitFunc(func, False, timeout);
end;

Nice to know :P

CallProc is also new for me.

Let's delete this thread then.

 

Heh, doesn't mean the thread isn't useful :) Nice to see people contribute
