char* trailFlags;		   // array of flag bits for trail points

.....



bool someBool = CalculateBool();



trailFlags[index] = someBool ? 2 : 0;

I'm unsure as to how the integer value of 2 or 0 is stored as a flag bit char in C#. 0 appears to be stored as '0x002f6020' in C++.

How would I do the same in C#?

This should work the exact same way in C#. I'd wager you're looking at the value of trailFlags rather than the value of trailFlags[index] - these are not the same. trailFlags is the memory location that the data is stored at, trailFlags[index] is the actual data.

Direct3D has need of instancing, but we do not. We have plenty of glVertexAttrib calls.

in C# you can use pointers but unless you need to typesafe arrays are the better choice



int[] trailFlags = new int[flagLength];

bool someBool = CalculateBool();

trailFlags[index] = someBool ? 2 : 0;

I see now. My C++ experience is 'null'.
