unsigned local variable

Hey, with the following code i get errors for all the variables. I don't know what to do to fix it.

I have the following code:

Code:

---

        private void generateLand()
        {

            int iCount = 0;
            float fX, fY, fZ = 0;
            float fNx, fNy, fNz = 0;
            float fTu1, fTv1, fTu2, fTv2 = 0;
            float fLVX, fLVZ = 0;
            int iColour = 0; 
         
            Landscape = Scene.CreateLandscape();

            Mesh = Scene.CreateMeshBuilder();
            Mesh.LoadXFile("..\\..\\plane.x");
            iCount = Mesh.GetVertexCount();

            for(int i = 0; i < iCount; i++) 
            {
                Mesh.GetVertex(i, ref fX, ref fY, ref fZ, ref fNx, ref fNy, ref fNz, ref fTu1, ref fTv1, ref fTu2, ref fTv2, ref iColour); 
                Landscape.SetHeight(fX, fZ, fY, true, false, false); 
            }
            Landscape.FlushHeightChanges(true, true); 
            Landscape.ComputeNormals(true); 
           
        }

---

This is the error that i get for all the variables:

Use of unassigned local variable 'fX'
Use of unassigned local variable 'fy'
...etc

How can i have to fix this??

float fX, fY, fZ = 0;

This line declares the varibles fX and fY, but it on initizlizes fZ.

You need to seperate the variables out.

float fX = 0;
float fY = 0;
float fZ = 0;

The error message is clear enough. It clearly says that you have not initialized fX & fY. Similarly for other variables too.
