GET VERTEXDATA U This command will return a float representing the V-Data value of the locked vertexdata.
Syntax
    Return Float=GET VERTEXDATA U(Vertex Index)
    Return Float=GET VERTEXDATA U(Vertex Index, Stage Number)
Parameters
    Vertex Index
Integer This value is an integer number such as 1.
    Stage Number
Integer This value is an integer number such as 1.
Returns
This value is a float number such as 0.5
Description
This typically is used to specify the vertical position of where the vertex grabs its texel from the associated texture, usually between 0.0 and 1.0. An optional Stage Number can be used to access UV data in secondary stages of the vertexdata.
Example Code
    rem Create simple plain and read its 4 vertices (plus any indices)

    if get maximum vertex shader version()>0

     make object plain 1,100,100

     lock vertexdata for limb 1,0

     vmax=get vertexdata vertex count()

     for v=0 to vmax-1

      x#=get vertexdata position x(v)

      y#=get vertexdata position y(v)

      z#=get vertexdata position z(v)

      nx#=get vertexdata normals x(v)

      ny#=get vertexdata normals y(v)

      nz#=get vertexdata normals z(v)

      diffuse=get vertexdata diffuse(v)

      u#=get vertexdata u(v)

      v#=get vertexdata v(v)

     next v

     imax=get vertexdata index count()

     for i=0 to imax-1

      vertindex=get indexdata(i)

     next i

     unlock vertexdata

    endif
