Under Texture Attributes Class it has functions like

 void    setCombineAlphaFunction(int index, org.jagatoo.opengl.enums.TextureCombineFunction combineAlphaFunction)     
 void    setCombineAlphaSource(int index, org.jagatoo.opengl.enums.TextureCombineSource value)
 void    setCombineRGBFunction(int index, org.jagatoo.opengl.enums.TextureCombineFunction combineRgbFunction)           
 void    setCombineRGBSource(int index, org.jagatoo.opengl.enums.TextureCombineSource value)

The question is how do we know the limit value of the index. What do this index do ? Is it related index to the number of TextureUnit ?

The index ranges from 0 to 2. It is directly mapped to the OpenGL constants

Code:

GL_OPERAND0_RGB_EXT
GL_OPERAND1_RGB_EXT
GL_OPERAND2_RGB_EXT
[code]

These are used for the function
[code]
glTexEnvf( GL_TEXTURE_ENV, GL_OPERAND0_RGB_EXT, ta.getCombineRGBFunction( 0 ).toOpenGL() );

Please read the OpenGL docs about this. Tbh. I don't know, what they do.
