Turbulence simulation

float count =
        Math.Abs(end.X - start.X) > Math.Abs(end.Y - start.Y)
        ? Math.Abs(i1 - i0)
        : Math.Abs(j1 - j0);

what are “?” and “:” for in front of Math.?

[laurent_delrieu]

I didn’t write that part so I am not used with the notatiob. It must be Linq notation that replaced if then. So one line instead if 7 lines.

If Else in LINQ

[DanielPiker]

The ternary operator ‘a ? b : c’ is a convenient way of writing a conditional in one line

?: operator - C# reference

(it’s standard in C#, doesn’t need LINQ)

Someone code a 3d version.

Could you help me explain what is condition in the code? is for get a float number?

@laurent_delrieu

float count =
        Math.Abs(end.X - start.X) > Math.Abs(end.Y - start.Y)
        ? Math.Abs(i1 - i0)
        : Math.Abs(j1 - j0);

explain what is condition in the code? is for get a float nu

if(Math.Abs(end.X - start.X) > Math.Abs(end.Y - start.Y))
{
count = Math.Abs(i1 - i0);
}
else
{
count = Math.Abs(j1 - j0);
}
