I haven't done anything with this program since 11/08. I brought it out to update and finish it.

The program compiled (dbpro7.2 or 3) correctly and worked fine.

The first thing I saw when I loaded the code into the editor (7.5) was the the editor did not recognize the apostrophe (') as a rem character. After taking care of that problem, the code compiled without error. The only problem, I was greeted with a blank black screen instead of the graphic background and menu buttons I expected.

Did you turn on syncing? Sometimes when you turn on syncing you need to add a quick SYNC to see the next SYNC.



Your code is a bit weird too. You clear the screen then GET IMAGE #1, then clear the screen again and LOAD IMAGE #1. Why grab a blank image only to overwrite that same image number by loading an image later? And why are you clearing the screen over and over again... all that does is slow it down.

This is all you need:


I'm not sure if you even need SET TEXT SIZE 14 since you never change the text size above that command. The only way it would be needed if it was earlier in the code thats not shown. You really should use .pngs instead of .bmp too. .pngs allow you to use transparencies and they are much smaller than .bmp.

NOPE! Your code snippet brought in the same results that I've been getting. The prog compiles and then presents a black screen with an over sized cursor.

BTW I compiled and run an earlier version of the prog in codesurge and everything worked as intended. I compared the codes and could find no differences. There are differences, but not in the areas that we are looking at.

If you are interestd in helping me out, I can e-mail you complete prog code. I don't want to impose but am interested in finding why this won't work.

Ah. Well, it was a shot in the dark without more code.

Yeah, you can email it to me if you want. I updated my profile so you should see an email button right under my signature. An easier way though is zip up your programs folder and attach it to your next message. That way you get the benefit of the entire Darkbasic community helping you instead of just me.

Are you only loading images?

I have had several instances where I didn't get the "image does not exist" error while the media definitely didn't exist. Instead, DBP chose to create a huge, completely black transparent image.

Furthermore, it seemed that this behavior only occurred with specific file types (I can't really remember which one, but I imagine bitmaps to be one of them).

Cheers!

I have found the answer to my graphics problem!

The settings on my twin Nvidia 9800GT video cards were not correct.

I looked at your code and I must say I'm thrilled you're working with the Zork Tutorial by Pluto. I love Zork so much my last name is an item from Zork.

The code you sent me ran fine after I put in a starting SYNC right after syncing is turned on.

I noticed that the code went to the main_menu subroutine before sync was turned on. That was the first thing I changed after adjusting my video cards. The adjustment gave me the background graphic but no buttons.

I hooked up my standby computer and found another copy (and later version) of the prog. It works pretty good but a few of the routines are out whack. The starting menu works fine.

I compared the two versions of code and changed the earlier version to match the later...still no buttons!

That's weird... it worked fine for me (see attached image). Is there still a SYNC within the DO/LOOP?

It's the FREEKING editor! I had the screen resolution set at 'full screen', 640/480/32. DZ didn't like it and wouldn't give me any buttons. Set at 'fulldesktop screen', and 640/480/16 everything works fine.

I like CodeSurge a whole lot better the Synergy IDE...BUT!

As for your code snippet, exactly like mine except I turned my sync on before the gosub Main_Menu and then put Sync's where they were needed.

I'm glad you figured it out. It's annoying when your code is just right and something else makes it not work.

I prefer to use BlueIDE myself. It has a handy code library you fill up with your own code snips.

The idea of code snippets sounds interesting. I'll give this blue IDE a go.
