How ok is it to copy Unity Editor Code for a public package?

Hey,

there's a lot of Unity Code that is internal for no apparent reason. I could use reflection but that might break my package later on if anything changes. How ok is it to copy a small bit of code, especially if it's mostly of mathematical nature to my small package? Specifically in my case I'm talking about this function in MathUtils.cs:

Code (CSharp):

1.         internal static float RoundBasedOnMinimumDifference(float valueToRound, float minDifference)
2.         {
3.             if (minDifference == 0)
4.                 return DiscardLeastSignificantDecimal(valueToRound);
5.             return (float)System.Math.Round(valueToRound, GetNumberOfDecimalsForMinimumDifference(minDifference), System.MidpointRounding.AwayFromZero);
6.         }

 

As referenced at the top of that repository, this is the license for the code in the Unity reference repository: https://unity3d.com/legal/licenses/Unity_Reference_Only_License

IANAL, but if you were to be inspired by this small code snippet and write something similar, I think you'd be fine.

 

Thanks, that's exactly what I mean. I've read the license and strictly speaking it's not allowed, but on the other hand there aren't that many ways to round based on minimum difference. So I guess I'll just write my own code inspired by Unity.

 

If you want to use it verbatim, you could try asking Unity directly. Though you might not get any response to that kind of question.
