Improved error - 05/18/14 16:54

Hey guys,

was just working again with gamestudio and noticed that debugging is just a PITA.

So i wrote myself a little error message that allows me to improve custom error feedback:

Code:

void cerror(int errorCode, STRING *text);

This function allows you to show your custom error codes.
The big difference is that cerror allows you to suppress specific error codes by pressing "Retry".
The function will still log into the diag file but will not show any error message ingame.

Also to be mentioned that the function resets the keyboard via key_pressed(-1) to prevent keys to be hold after an error message.

Here's the snippet:

Code:

void cerror(int errorCode, STRING *text)
{
	static int killed = 0;
	static int suppressed[1024];
	
	// Throw error if error code is out of bounds...
	if(errorCode < 0 || errorCode >= 1024)
	{
		cerror(0, "errorCode out of bounds!");
		return;
	}
	
	// Build error name
	STRING *str = "#100";
	str_cpy(str, "Error ");
	str_cat(str, str_for_int(NULL, errorCode));
	
	// Log error
	diag("\n"); diag(str); diag(": "); diag(str);
	
	// Don't show message if system is killed or error is suppressed
	if(killed) return;
	if(suppressed[errorCode]) return;
	
	int result;
	
	result = MessageBox(hWnd, _chr(text), _chr(str), 0x06 | 0x10);
	if(result == 2) // Cancel
	{
		// Kill the program
		killed = true;
		sys_exit(NULL);
	}
	if(result == 10) // Retry
	{
		// Suppress the current message
		suppressed[errorCode] = true;
	}
	// Suppress invalid keys
	key_pressed(-1);
}

Have fun!
Felix

Small nitpicking: You can shorten your message generation code by doing this:

Code:

diag(str_printf(NULL, "\nError %d: %s", errorCode, _chr(str)));

Also solves the undefined behaviour that you are generating there

what undefined behaviour do you mean?
