Help me out

« Posted 2004-01-24 03:57:48 »

Alright, so I decide to implement Vertex and Pixel Shaders using Xith3D and binding the programs in a process that is close to Texture binding.
I fire up netbeans, go to G:\Xith3D\xith3d\src\com\xith3d\scenegraph, create an abstract ShaderProgram class, and then a VertexProgram class that extends it and try to compile it.
Nada, I'm greeted with the following error message

G:\Xith3D\xith3d\src\com\xith3d\scenegraph\VertexProgram.java:50: cannot resolve symbol
symbol  : class ShaderProgram 
location: class com.xith3d.scenegraph.VertexProgram
public class VertexProgram extends ShaderProgram {

symbol  : variable super 
location: class com.xith3d.scenegraph.VertexProgram
        super.duplicateNodeComponent(original,forceDuplicate);
        ^
2 errors

I scratch my head thinking to myself, maybe I didn't spell the name right? But I wasn't that careless to do such mistake, everything looked and felt just fine, and yet I couldn't compile sh|t.
So I load up Texture2D from the same directory, rename it to TextureTest and made the constructors changes accordingly, compiled just fine. However, trying to declare a TextureTest variable in any other class that is in the same directory would return a cannot resolve symbol error message...
This never happened to me before, and it drives me totally insane.
PS: This is a brand new pc that I built myself

Tool completed with exit code 1

PS: Could someone with Xith3D source installed on his pc try and compile the two previous classes in the mentioned directory.

If failed on me again Cry

Damn I wonder why making a class by totally copying another one and modifying the title as well as the constructors would result in such error.
Every other class that comes with xith3D works and compiles just fine.
