The finished product looks freakin sweet!! Great work m8

I totally agree, that's a spectacular side-scroller.

Cheers fellas, its these kind of comments that keep ppl motivated.

Totally agree, watched your videos and was very impressed by your progress

Well done man.

Motivation is so hard to come by.

Last thing I worked on was this traffic light demo thing.

It had a list of tasks that updated each frame.

I totally agree motivation is half the battle in a good project, innovation is the other half. Getting motivation to start a project is easy, having the motivation to finish is another thing all together.

Currently I'm working on a base engine for all projects to come. It's almost done, I just have to implement collision detection. But for some reason it goes all fluky.

I'm working on a console dictionary. Nothing much, but I've been wanting to make this for a long time. I barely have the skills required. I've never used the STL before, so that's a major challenge. I'm also having troubles parsing text-files.

The past snow days we have been having has allowed my to get off my ass and get stuff done. I got together some of the space shooting game (as far as single player goes) and made some decent sprites thats good enough for building the game.

Anyone know of any hosting sites for images?

I doubt there would be much interest for this game outside my circle of friends, but I know they want to play it and I want to make it, so it works.

This is a fight type card game, the premise is that you are a bunch of school girls, beating each other up using these attack/weapon/combo/specialty cards. There's defense cards and some of the special cards can completely reverse an attack. It sounds silly, but it encourages loudness, humor, and violence, so it goes down well with us.

http://www.atlas-games.com/product_tables/AG1100.php <- This is a link to the product site, you should definitely consider picking this up if you want something fun and simple to get into.

The scope of the project is to take this card game and make it enjoyable through a PC interface. The idea is to be able to play this together, even when we can't get together. To do this, I will be using DirectX, a networking API for connectivity, voice/text chat, and C++.

I say scope as I'm still in the early stages of this game. I am following a book by Jonathan Harbour called:
2D Advanced Game Development(http://www.amazon.com/Advanced-Game-Dev ... 121&sr=8-1) which gives you a nice looking Direct X 2D engine that will more than adequately fit the needs of this project. I will also be using Raknet(http://www.jenkinssoftware.com/) for the networking side of things as I'm not too strong in terms of network programming.

I just wanted to update here, as I've gotten pretty far with this engine. I'm still working out of this book but it's been a slow process with family and work everything. I've gained quite a bit of knowledge of what goes into a game engine and a good refresher on making code reusable in ways I hadn't thought of before.

What's been accomplished thus far:

2D and 3D rendering(3D is largely unoptimized but used for various things)
Animation
Input
Audio
Entity Manager
Font(most recent)

What's left:
Physics
Math
Multi-Threading
Lua
Networking - using Raknet

http://www.youtube.com/user/Trask899 - is my youtube page, so far it just has a quick video showing off the font class. I do plan on posting more videos, but not until I have some original material to share.

Subscribed =D. And How good is that book? I just recently ordered a book by John Harbour called Beginning Game Development, someone recommended it to me to learn DirectX. I was considering buying that book, so I'd love to know what you think of it =p.

I had actually heard of the game before, but have never played it myself. I'm exciting to see how your project turns out, so I can try it myself =D.

I really like the book at it shows what's goes into a game engine, while using DirectX 9.0c. This book will NOT teach you directx, lua, STL, c/c++, but will give references to other books to further go into said topics. The whole 1st 2 chapters just dives into so much code before explaining one bit of the why and it assumes that you have a decent background in C/C++. That's why I like the book... I know my basics, i don't need another book explaining how/why to use a For loop, I just needed something to show me how to put it all to good use and that's what this does.

So again, it's not going to hold your hand through any of these topics, but merely teach you how to use it in a reusable engine for 2D projects. I do recommend it, Jonathan Harbour was a teacher of mine before I ran out of money to finish school, so I am used to his style of teaching which is usually to throw a bunch at you, wait for you to catch up, explain bits here and there then teach you something new while showing you a more efficient way to do what you previously learned. Which means, the first chapter with an example on how to display a sprite won't/shouldn't be the way you actually display a sprite by the end of the book as so much more is added. Here's the book's Table of Contents to give you a taste of what it has:

Sounds awesome. I'll have to pick up a copy after I finish reading the one I already ordered (if it'd ever get here >.>).

Well, for school I'm working on a program called Mytunes. Mytunes is a java version of Itunes (only it is fake and sucks). At home, me and three friends are tossing around the idea of making an 2D RPG. So far we haven't gotten to coding yet (due to how little time each of us has), but it seems that we will be starting soon! Wish us luck
