It took me a while, but I finally got my next game done. This is the culmination of everything we have done so far in this game development project. We have built upon all the techniques and skills from all the chapters before us to make a fun retro style arcade game.

The main point of Meteor Defense is to protect cities from falling meteors by shooting missiles to intercept them. As the game progresses, more meteors will fall at faster rates. Once all four cities are destroyed, the game ends.

So, it has been a while since my last update on my Beginning Game Programming challenge. But it is coming along again. This week, I completed Chapter 16, Creating Backgrounds for your games. In this chapter, we looked at creating a star field for your game. In the book this challenge is based on, the author created a class to add a field of stars to his games. Lucky for us, HaxeFlixel already had one. We had actually used it earlier in this challenge.

It has been a long time since my last update and I am happy to be back. I have been working on this game for a while. I started it nearly a year ago and life kind of got in the way.

In chapter 14 of Beginning Game Programming, we are challenged to make a gallery style shooter. The game in the book is an office battle game, but I didn’t feel that such a setting was appropriate for us. So I changed the theme to a game about killing bugs in a kitchen.

In Chapter 15, the book teaches us about animating sprites. Since we already used animated sprites in previous games, I combined the two chapters. But I also decided to use something we touched earlier in the Memory game, tweens. This tween is different from the ones we used in Memory. This one causes the sprite to loop around the kitchen.

In Chapters 12 and 13 of Beginning Game Programming, we learned how to add sound and music to games. Thankfully, HaxeFlixel makes doing so easy. The projects for these chapters were to just add sound and music to two existing games, Memory and Dino Cross. So I did that, but I also made a little toy to play with some other sound and music options.

Chapter 11 of Beginning Game Programming is our third complete game of this series. And honestly, it was probably the easiest of the 3 to make. The reason for this was all the work we did up to this point to build out our skills.

I also had a good wind behind me as I made it. Completing Unicorn Dash and the two planets examples really helped motivate me to finish this game.

For the latest examples for Beginning Game Programming, we learn about sprites and different sprite behaviors. In these next two examples, we don’t really break a whole lot of new ground, but we do get to play with a few things we have only touched up, as well as play with some existing Flixel Classes.

Both of the planet examples, from Chapters 9 and 10, we start off by generating a field of stars that zooms along in the background. This is a relatively simple implementation as the wonder developers behind HaxeFlixel made it. This class is a drop in solution for any space based game.

After a too long hiatus, I am finally back with the next section of my game development project to convert the game code in a game book to HaxeFlixel. Chapter 8 of Beginning Game Programming gave us a Light Cycles (the game with the motor cycles from the movie Tron) clone. So that is what I did. I decided to give the game a different theme, Unicorns. This was partly to make a game that has a theme my youngest daughter would love.

This project started off great. I was able to create the base game and add two players, both playable via keyboard and game controllers. That was the easy part. Then came the process of drawing lines behind the players. This is where I hit a snag.

In my Crop Circles project, I drew lines between circles and the way I did it then worked for that example. But that code just wasn’t going to work here. I had to find a new method. But this was not as easy as I thought.

In my last post, I mentioned that I probably wouldn’t be writing a dedicated blog about the Chapter 7 UFO2 example from Beginning Game Programming. At the time I wrote that, I was thinking to myself that the introduction to Game Controller input would be fairly straight forward and I wouldn’t have much to talk about. But I was wrong.

Before we get into the first full game made in my current project, I wanted to share a few things from Chapter 5. Chapter 5 introduced the developer to player input with the keyboard. In this chapter, we made a little “game” that lets the player fly a flying saucer around a night sky. Fun, but not super interesting. But with what we learned about player input, we can start making real games.

Chapter 6: Memory Game

With the introduction of player input, Chapter 6 gives us an example that uses mouse input. This memory game is a pretty simple concept going back decades or more. You take a deck of cards and lay them face down and try to find all the matches.

I actually created one of these a long time ago when I was still working with Flash and Actionscript, called HexMatch. That SWF is no longer playable and I doubt you would be able to get the code to compile. So I thought it a great time to create a new matching game. Introducing BGP: Memory.

Just finished up Chapter 4 of Beginning Game Programming by Michael Morrison. This chapter taught new game developers about bitmaps and how to use them in their games. Since HaxeFlixel handles all those details, I didn’t need to write up a class to read and display them. So I jumped right to the example at the end, A Slideshow.

For this, I used it as an introduction to HaxeFlixel’s sprite animation functionality. The FlxSprite class has some built in animation functionality that you can use to to create a slideshow effect.
