Adding an Object Builder

Now we can start writing our object builder class. Let’s create a class in the package com.airhockey.android.objects called ObjectBuilder. Start out with the following code inside the class:

​ 
​private​ ​static​ ​final​ ​int​ FLOATS_PER_VERTEX = 3;
​ 
​private​ ​final​ ​float​​[]​ vertexData;
​ 
​private​ ​int​ offset = 0;
​ 
​ 
​private​ ObjectBuilder(​int​ sizeInVertices) {
​ 
vertexData = ​new​ ​float​[sizeInVertices * FLOATS_PER_VERTEX];
​ 
}

There’s nothing too fancy here so far. We’ve defined a constant to represent how many floats we need for a vertex, an array to hold these vertices, and a variable to keep track of the position in the array ...
