LWJGL tutorial series on how to create a 3D Java game with OpenGL!

This week we add per-pixel specular lighting to the game, allowing for shiny looking materials!

Common Problems:

-Watch to the end of the tutorial! Quite a lot of people missed out the bit where I multiplied in the "reflectivity" variable.

- Make sure that you are calling bindAttributes() *before* glLinkProgram() in the ShaderProgram constructor. Also, check that you spelled the "in" variable names correctly in the "bindAttributes()" method in the StaticShader class.

-If your dragon seems to have lots of white and black patches then it could be one of 2 problems:

1. Your texture dimensions might not be powers of 2 (64x64, 128x128, 256x256 etc.)

2. If they are powers of 2 then try adding the following lines to the end of the loadTexture() method, just before returning the texture ID:
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MAG_FILTER, GL11.GL_LINEAR);
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MIN_FILTER, GL11.GL_LINEAR);
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_WRAP_S, GL11.GL_REPEAT);
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_WRAP_T, GL11.GL_REPEAT);
