I'm sure this is my problem, but I'm not sure what my problem is. Could someone look at this code and tell me why it gives me an error saying the color (it's supposed to be 32) isn't 16, 24, or 32.

My code says this:


And my file (Presets.dat) says:

You could eventually do like this:


If I remember correctly you need to read data from a file as strings in darkbasic, then you can convert to values. That code works here

Hope that helps!

Thanks so much! I really apreciate that. But if it's true that you have to read it as a string and convert it, what is the point of the other READ commands? Like Read File, Read Long, Read Byte etc.

I never thought about that... But if I compile this code:



The text document contains a "1".

Now when it's getting printed in the compiled program it writes "49"...

So the data must get twisted somehow... That's why I read data from a file using strings...

to read the file as it stood in the first post (with no quotes) read long is what you're after

@___:

That dosn't work...(Just tried), as it shows in my example the data is somehow getting "twisted" if you don't read it as a string.

I just get an "Runtime Error 1502 - Screen depth is illegal at line 23"

Remember you have 'secret' characters at the end of a line - like the 'line return' character.

Read string seems to ignore these, but read long (etc) may pick them up in ascii form.

If you check out the WIP thread, I've been helping on the Templar Quest thread and in that I have some fairly indepth text file reading. Feel free to take a look.

val() is your friend

(as is len())

I always used to use read string instead of long - the one time I try and go fancy, look what happens...

You could use read byte for this assign 2 bytes for screen width, 2 for screen height and 1 for bit depth. bytes would read as

Width(4,0) 4*256+0
Height(3,0) 3*256+0
Depth(32) 32

The data is not twisted it is stored as bytes thus a number over 255 takes up 2 or more bytes, a number over 65536 takes up 3 or more, etc.. DB will let you store greater values as bytes but as a precaution I always use standard size bytes to avoid a possible problem later.

PS. this method works well if you want to make it so you can import characters from other games (i.e. diabloII) or whatever, into your own game.

49 is the ascii value of 1. You cannot enter integers in notepad and read them the same in DB. You have to read up on what Hobgoblin Lord mentioned and learn about memory sizes and uses.
