Hello, This may Sound abit stupid, but it would be helpful if someone could explain to me if it is possible to bypass an error.

By this I mean, for example, if i got an image does not exist error, or invalid image number would there be a way to force the program to save before closing?

I'm not sure,if that is possible, but you could make your own paste image command which checks first if the images exist, and if it doesn't, it writes the file, image number etc to a file, and then exits with a message box or something.

And another thing: there are no stupid questions, only stupid answers

Yeah, as Bobbel suggested you can check if the image exists before you try to use it. Do it right and you won't have to do an emergency save before it quits prematurely because it won't quit when you don't want it to.

I understand that it would make more sense to fix the problem. however. i'm not sure whats causing it. and it doesn't get the error until i advance so far into the Game. So it would be easier if I could restore my progress afterwards. thanks for the advice. i'll give it a try

Np.

When I'm not totally sure where a bug is I create a debug file... basically all it does is store strings of text from the program as the program is running to show you what your program is doing.



The above will eventually error out because it'll pick an x and y coordinate that's too close to the edge of the screen for x+50 and y+50 to be within the screen resolution. To find out why it errored out open debug.txt and look at the last line. That last line should be coordinates that are beyond the screen size. So if you do the same thing for your program writing out the image numbers being used (before their used) you'll quickly see which image number doesn't exist by looking at the last line.

But of course if you really can't find it that's why the Darkbasic forums exist. Post your code and we'll do our best to find the error(s).
