Bug of Unity or not ?????

Guys, I created a variable that receives a value perlin noise, the code and that:

Code (CSharp):

1. float Wave = PlanetFactor*Mathf.PerlinNoise(X+PlanetSeed/Mathf.Sqrt(X),Y+PlanetSeed/Mathf.Sqrt(Z)+Y);
2. int WaveInt = Mathf.FloorToInt(Wave);

And the mysterious error I get and this:

Code (CSharp):

1. "NullReferenceException: Object reference not set to an instance of an object
2. (wrapper unknown) uint16:PtrToStructure (intptr,object)"
3. And this:
4. "NullReferenceException: Object reference not set to an instance of an object
5. (wrapper unknown) uint16:PtrToStructure (intptr,object)"

Can anyone tell me how can I fix it?
Sorry for the emoticon, text interpreter site detected a smiley where the error was one : P

 

No idea - should report a bug. Use code tags to avoid etc

 

Does PlanetFactor and PlanetSeed actually return a value?

 

If you're unsure it's a bug, it's not a bug.

 

The PlanetSeed and Planet Factor are used only to multiply the perlin noise (I have not mastered well), the problem is that whenever I put factor in more than 1.5, it's this error.[/QUOTE]
