Try Except Finnaly Statments --> Questions

[shadowrecon]

So im trying to learn the proper use of these, because they do not throw errors and stop the script if setup properly and you can account for the errors and ifx them. problem is ive never used them a whole lot, and i was following a tut on the and below is one of the examples. How can i do the same thing that is going on in this Tut in scar? The errors that are coming up is 'On' , 'Message', 'ClassName'

 var
 number, zero : Integer;
begin
 // Try to divide an integer by zero - to raise an exception
 Try
   zero   := 0;
   number := 1 div zero;
   ShowMessage('number / zero = '+IntToStr(number));
 except
   on E : Exception do
     ShowMessage(E.ClassName+' error raised, with message : '+E.Message);
 end;
end;

They are a lot easier to use

 

[sCAR]begin

try

PossibleFailue;

except

ItFailed;

finally

DoesThisAtTheEndEitherWay

end;

end.[/sCAR]

SCAR's engine does not support "on...do":

 

[scar]var

number, zero: Integer;

begin

try

zero := 0;

number := 1 div zero;

ShowMessage('number / zero = ' + IntToStr(number));

except

ShowMessage('Error raised');

end;

end.[/scar]

He is trying to get the actual details of the Exception raised a la Delphi.

 

SCAR's engine does not support "on...do":

Which it sadly does not appear to support. Not widely used but can be handy in certain circumstances.

Isn't that what I said?

So just to clarify with scar, if i use a try and except statement, and it was to cause an out of bounds or some other kind of error, it would not terminate scar instead proceed to the except statement?

[Bixby Sayz]

The logic goes something like this:

try
 // Code goes here
except
 // If an error occurs this code gets executed
 // without crashing SCAR
finally
 // regardless of what happens this
 // *always* get executed
end;

You don't have to use all the parts.

try
 // code
except
 // error handling code
end;

or

try
 // code
finally
 // code to always get executed
end;

Doesn't work with everything. Plugins (such as smart) seem to still crash scar.

Ok thanks, i just wanted to clarify, i wish i would of known this a long time ago, this could fix the occasional bank issue i have with map.scar being out of bounds =p yay! lol
