It’s been a while, but boy have I been busy! As the blog post title suggests, I am now a certified Java programmer, with a 90% passing grade. I won’t lie, it wasn’t easy, but it’s done! While I may not be working with Java in the immediate future, it looks like PHP is on […]

This is a little snippet of code I wrote for destroying an object in a game I’m working on with pals. See the comments in the code for an explanation.

In this post I’ll outline two ways of making your JFrame full screen, one for NetBeans JFrame Form, and the other for those hand coding their JFrame from […]

This post is about the Tower project, my involvement, experience and review of the project and processes. To start with, below is the project requirements. […]
