So i'm just trying to learn DarkBASIC all on my lonesome.
Just started earlier today.
And I ran into this.
For a simple Dice rolling game,
Dice1 = RND(5)+1 has 100/100 times given me a 0.
Dice3 = RND(5)+1 however is giving me random numbers.

Now, for the sake of the code, it isn't an issue I guess.
This is more a question of WHY.
The only thing i changed was flipping all those Dice1's into Dice3's
And it started working.
Really odd...

Welcome to TGC DrunkenAdvice and the lovely forums of the DBP crowd!

Try adding:

Randomize timer()

To the top of your program. RND() uses a seed value and Randomize sets the seed for the random number generator. By setting it to the timer() it will be a different seed every time your program start (Though this have never been the case for me since I've always got random numbers that are different every time)

I've never heard of this issue before. How are your printing it to the screen to find out if the value is incorrect? Like maybe you've missed a letter or something that could through it off!

It's difficult to diagnose a problem without seeing the actual program. None the less the following seems to work as expected..

The only thing I can think of that would cause that, is constantly setting the randomize seed to the same value. If not, well it has to be a problem somewhere else in your code.

Well I would pull it up and show you, but for some reason every save I have made is blank.
So that's cool

Anyway, yes i did have the seen randomized
And the only thing i did to fix the code was change all instances of "Dice1" to "Dice3"
And it worked, I haven't revisited the issue since I'm far past.
I was just kinda wondering if there was something I was missing.

Since its not a known issue or trick or w/e
Im sure the issue was some lil syntax error that I accidentally fixed.


Anyway thanks for the quick responses!
Off to try and figure out why my saves can't be revisited...

Probably you reset it somewhere in the code to 0 before you print the result to screen, or you read wrong variable.You may have Dice1 = rnd(5)+1 and print Dice_1 for example.

You might also have a use for this dice roll plugin I wrote...

You must have misspelled Dice1 and corrected the mistake when you changed it to Dice3. I can be 90% sure of this because you say the value was always 0, and zero is the default value of an initialized variable, so you were more than likely printing the value of a new variable that hadn't been assigned any value.

This is an issue with Basic, you have to be very careful with your typing because if you spell a variable name wrong the compiler wont tell you, it will just create a new variable with the misspelled name.
