I apologize in advance I am a noob.

Ok, so I get a null pointer exception whenever I try to use the set() function.

Code:

// the x and y are floats
      position.set(x,y);

So the only way I can set the value of a vector2f is making a whole new vector2f and then setting its value to the original.

Code:

// the x and y are floats
      position = new Vector2f(x,y);

What am I doing wrong?

Did you initialize the variable 'position' before trying to set its x and y? Look at the last post from me here if you don't know what I'm talking about.
