Question

I am currently trying to learn how to make games in 3D, so I watched a few YouTube-Tutorials. In one Tutorial I found this method:

int floorTexture = glGenTextures();
{
  // ...
}

Source (Line 215)

I have never seen this type of method (I think it’s a method) before, so I now have two questions:

1. Can I add parameters to this method? This code doesn’t work

   int texture (String texturename) = glGenTextures();
   

2. What does the =glGenTextures() do?

(I want to load different textures in one method.)

Answer 1

That’s not a method declaration – it’s a method call followed by a block.

The block itself is unnecessary, and basically just confusing. Heck, the fact that the main method is nearly 500 lines long is a good indication that this isn’t code you should be taking hints from – at least in terms of structure…
