I am convinced this is not a user error... I've gone through the logic a hundred thousand times, and I don't understand what is wrong with my code. I'm using an older version of DB Classic, so maybe it's a bug. Perhaps there's a way around it? Well, long story short, I'm trying to create a very simple yu-gi-oh dueling game so I can duel my friends online. (I know, I'm truly the worst type of nerd...) This game will not be any more structured than real life, so cheating would be easy, but this is only for fun among friends, so I'm not too worried about that. I wanted something quick and simple to make.

So, in the very beginning of the program, I have to load all the card images. (data for each card will be inserted later) I have it set up so you can throw jpegs into a folder called "Cards", and the program will then go through and load all images in that folder...well it SHOULD. That's where the issues begin. What's wrong with my code?



Any and all help appreciated. -OP

Did my thread disappear for good just because I edited? O.o
Just in case, I'll post this before I go to bed then.

Code for loading a bunch of Yu-Gi-Oh card images:

I saw this in post approval - basically, the problem is your code.

Instead of trying to load something, print the filename to the screen. Then ask yourself what it means to load "." and "..".

Whenever you do a checklist for files, the first two items in the checklist are always "." and "..". I don't know what the difference between them is, but they both link to the parent folder (it's like clicking to go "up one level" in the Windows file browser).

Thanks! You were both a big help. According to DB, I'm able to load the images using this code:

However, "paste image 1,150,150" will not work. It says the image does not exist. :S So something must still be wrong...

@Rakansen

Both IanM and Robert The Robot have valid points. You do have the right idea though, since . and .. are the first two elements in the checklist, skip the first two and start at 3:




Also, another useful technique is to get the path of where the program is running from. Try this program out. It gets the path where the program is running from, prints it and also prints a directory listing. It then moves up one level and prints that out.

In case you are moving through many directories and need to get back to where the program is running from you can then use set dir homedir$

Hope that helps you with your problem

Thanks again. I tried this code:

and it started working. Unfortunately, I had to leave for work before I could continue. Now that I've returned, it stopped working. Now I'm really confused... I don't remember changing anything else... Who knew this could be such a big task?

OH, never mind. I figured out what changed- it wasn't the code, there was a text file inside the "Cards" folder. Looks like I'll need to create a new directory for storing card information.

Also you can check for file extensions which could eliminate the need to start counting at 3 and account for any wierdness that changes the order of the strings. The ".jpg" assumes you only want jpegs. It could be .bmp or whatever.

perform checklist for files
for card = 1 to checklist quantity()
card$ = checklist string$(card)
if len(card$) > 4 and right$(card$,4)=lower$(".jpg")
load image card$,card
endif
next card

Enjoy your day.
