I'm newbie in the F#, too.

Nevertheless, I can see that your code isn't clear for understanding.

Some questions, important to further answer:

  1. What is starting value of r?
  2. Has Game1 or Game1.m_Random or Game1.m_Random.Next some side-effects?

It is possible to unthinking translate this to F#, using mutables, but the translated code will look really awful from functional point-of-view.

Hi,

The full version method is -

1
2
3
4
5
6
7
8
int r = 0;

while (r % 2 == 0) 
{
   r = Game1.m_Random.Next(1,7);
}

m_fAngle=MathHelper.ToRadians(r * 45);

I'm just trying to get a random number between 1 and 7 and use it to create an angle. The problem I have is the while bit, I have no doubt my code will be bad from a functional point of view at the minute but I'm just trying to get to grips with the syntax

If so, then let's do...

1
2
3
4
let mutable r=0

while r % 0 = 0 do
    r <- Game1.m_Random.Next(1,7)

I guess you mean -

while r % 2 = 0 as 0 = 0 is a divide by 0 :)

Yes that worked! thank you very very much :)
