Question Referencing variables of different class and optimisation.

Question about optimisation:
I have two classes, one class responsible for calculating physics, the other contains coefficients that physics uses for calculations.

Code (CSharp):

1. public static class Coefficients
2. {
3. public static float[] someCoefficients {1,2,3}
4. }
5. public class Physics : Mono{
6. float[] localCopyOfCoeffs ;
7. void Start{
8. localCopyOfCoeffs = Coefficients.someCoefficients;
9. }
10. void CalculatePhysics()
11.    {
12.     //use coefficients for calculations
13.    //Should I use
14.     localCopyOfCoeffs
15.     //or
16.    Coefficients.someCoefficients;
17.    }
18. }

Considering performance - is it much better to keep the local copy of coeffs (cache the reference) or should I just reference these coefficients directly in CalculatePhysics.

 

You won't gain anything with this "local copy" approach. Both

someCoefficients

and

localCopyOfCoeffs

are just references to the same object in memory.

 

Ok, Thank You
