Life and Code

I loved Buzz Aldrin’s Race into space when I first played it several years ago. The things I wish I could change about that simulator are the things I am attempting to put into my own idea of a space race hot seat simulator. For example in BARIS, launches played the same videos over and over again, in a modern sim, there is no reason why these launches could not be dynamically simulated based on the current tech level. Even on a modest computer, using modern graphics techniques, it should be possible to create a compelling sim with dynamically generated and simulated mission launches. I am testing this concept with my Project First, I want to see how cool of a Space Race launch I can simulate with XNA.

I have started with a simple goal for now, model the crafts and locations to dynamically generate the Explorer I mission, not necessarily to real life spec. But to a decently realistic and good looking level of detail. To this end, I am working on modelling the Jupiter-C launch vehicle using correct dimensions weights etc. I will use this to create a pretty basic simulation in XNA and build on it adding stuff like the engine sounds I am also working on Here is a preview of some of the stuff I have coming

Audio:
The audio was created in Audacity using a high pressure cigarette lighter as the base sound, then I pretty much massaged it down a bit to get a nice roar. The start just uses reverb and amplitude changes to give the feeling of that initial surge at rocket startup. Pretty simple sounds to create so far. Kinda fun to be playing with audio again .

GVSS - My First XNA attempt

So, once again I have started playing with a new technology, Microsoft’s XNA. Thus far, I think it is one of the cooler things I’ve played with.

The download was pretty painless and after a few community tutorials, I have a decent grasp of the power that XNA gives the developer. XNA seems to work with both the Direct X ‘.x’ format as well as Autodesk’s ‘.fbx’ both of which Blender 2.49 exports. Blender, being free, is the perfect complement to XNA. I will definitely post more experiences later.  

My Toolset

• XNA framework 3.0
• Blender 2.49
• Audactiy
• Gimp

I am still working on finding a free physics package I can use on XBOX360 as I am now seriously considering getting a creator’s club account. So far, I have no complaints.

Not of my blog… I just realized that I have not updated this in a bit too long. Short story is I am being outsourced… That said, the blog will continue… I will be writing soon of my adventures with XNA… Another paradigm shift

5. Create <YourProjectName>Win.cpp containing:

#include <windows.h>
#include <stdio.h>

BOOL APIENTRY DllMain( HANDLE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved

I drafted this a while back. I think it is interesting now so publishing (5/19/2009):

In my opinion, one of the biggest worries of any IT organization is what I refer to as ‘Blind Monkey IT’. What this leads to in my limited experience is a lack of initiative and a ‘blind action’ mentality. Perfect examples of this are the pc support tech. who can’t fix your problem because it isn’t in his script. I know right now every manager is shaking their collective fist at me, but this seems to be the perfect way to make your team redundant. Ever wonder why the off-shore csr with the bad accent insists your problem is on his script. Now, don’t get me wrong documentation is a good thing but there has to be a stopping point.

I am always in need of very basic logging for my projects, here is the logger I wrote for my XPFF project, remember this code is as-is as the project is still very active:

Well I have finally decided on the concept I will move forward with as the game I will develop. This decision has been a long time coming. I think the genre I have decided on is rather underused and the game will be fun above all else. The work required is not too bad either, I will disclose more after I have fleshed out the design documents. A page here is forthcoming as well.

So I am all set up to write my excellent game (demo). I have come up with and shot down several of my own ideas. I think I have coder’s block. I know I have the ability to code this, however, I seem to be having problems designing. I think I need to just take some time off and unwind. The cold spell has actually given me a few ideas. We’ll see how it turns out I guess.

The last two weeks off work have been a very creative time for me. I have been playing around with a few tools that I can see making garage/one man game development easier. Before last week, I was very much into Irrlicht and Newton, but this all has changed. My toolbelt has been helped out quite a bit by changing perspectives. My new tools of choice jME (the jMonkey Engine), jME physics, Blender and MakeHuman.

JMonkey and JME physicis are pretty cool tools, for Java. The game/graphics engine is very well featured and the physics engine seems to be the same. They use jinput and LWJGL and provide very simple and useable starting points for creating games. I very much like both of these projects. C++ will always be the king of speed but Java doesn’t do that badly anymore.

Since I have been weaned from the high cost 3DSMAX and Poser, I have been using Blender. Blender has served me very well, it is an excellent tool. It provides functionality that you would otherwise have to pay high prices for. The place I have lacked here is in my ability to create good looking humanoids. Enter MakeHuman, this tool may not be as deep as Poser is but I really like the models it produces. The project seems to be heading towards a good place and I like it alot.

These tools are ecellent, and I have played with them quite a bit in the last two weeks. I am looking forward to finishing my demo now.
