Now, I said I wanted to get the editor written up before I posted the basic system, but I have had so many requests for it I thought I may as well get the base up and I can build on it as the system evolves. Before I get into the code, I'll explain a little of it's evolution. I first started...

Some of you that have come to this blog after going to the ReMix 08 conference are probably wondering, "Where is that source code Paul said would be here!?" Well, most of it is here, it's just smashed across a lot of posts. But, it's not all under one project ready for you to run and...

OK, I went back to my old threading code to port it to the 360 so I could start playing about with processor affinity (as promised last time) and found the compact framework for the 360 was a bit thin on the ground for parameterized threading, so I have re written the whole thing and it will now play...

Well I have done some basic threading in my job, basic stuff and thought I would try and put the basic threading I have done into an XNA Game Component. I am not saying this is how you should do your threading, my method is certainly not the only way to thread processes either and more than likely not...

Well, I started looking into this after a friend of mine asked if it could be done. I remembered the other week on Ziggyware that someone got a web cam to stream in an XNA app and so thought that the principle should be the same, taking the output, rendering it as a texture then applying it as you required...

As you have seen in the previous posts I have created 2D and 3D flame shaders based on the flame shader that comes with the NVIDIA SDK. When I initially created the 2D shader I found...

Hope the music is acceptable this time...

OK, here is the code sample for the flame shader I have adapted from...

[youtube]http://www.youtube.com/watch?v=0_qMAyr7RJY[/youtube] In this tutorial I am going to bind the emitter to a game agent, now you will have to forgive me as I have been very lazy, I have taken textures from the Creators Club particle example as well as some of the facing methods, have not bothered...

We have our classes so all I am going to do is now apply some pixel shader effects to both the particle system and the background image. I am going to describe how the pixel shader is applied to the particle emitter as the technique is the same for the background image. So, to our ParticleEmitter2D class...

I guess you know what Octrees and Quadtrees are so wont go into too much detail on them here, but they are basically a great way to hold static (none moving) game objects in groups for the use of culling and the like. As stated this is great for game objects that don't move, terrain, buildings and...
