Solved Generating a box

I'm trying to make a box around a certain location, but for some reason this isn't working out for me. This is what I have:

Code:

       
        int y_start2 = (int) Math.round(loc.getY())-8;
        int x_start2 = (int) Math.round(loc.getX())-8;
        int z_start2 = (int) Math.round(loc.getZ())-8;
        int x_length2 = x_start2+8;
        int z_length2 = z_start2+8;
        int y_length2 = y_start2+8;
       
        for(int x_operate = x_start2; x_operate <= x_length2; x_operate++){
            for(int y_operate = y_start2; y_operate <= y_length2; y_operate++){
                for(int z_operate = z_start2; z_operate <= z_length2; z_operate++){
 
}
}
 }

 

What isn't working? For what I can see, you're not even making any blocks xD

 

Nvm, I found out why. I had to use +16 instead of +8.

Yeah I made the question a little simpler and snippet out some code for the sake of getting an answer. It's actually a method that checks for resources in the area to define nodes.
