Question

I was wondering how to count an array in HSLS?
Say, I have an array declared in our effect file:

float2 Position[1];

And inside our source I set the parameter to something else
for instance:

Effect.Parameter["Position"].SetValue(MyVector2Array);

Under the shadering function how could I count the array? Would look similar to:

float4 PS_function(float2 tex : TEXCOORD0) : COLOR0
{ int Size = Position.Count(); }

Thanks in advance :]

The most simple way is to declare a constant that will define an array size:

const static int MAX_POSITIONS = 1
float2 Position[MAX_POSITIONS];
