After announcing this tutorial a few weeks back, I finally put in online for your learning pleasure. I do not know if I will be adding more chapters to this long tutorial, if any of you have some leads, you can always post a comment and I will look into it when the time permits me to indulge in UDK. I want to take the time to thanks again all my readers, some of you are really helpful in finding bugs that I miss. I have made some leaps and bounds in UDK thanks to everybody that shares their knowledge of this beautiful platform.
I added my test map and the source code for chapter 6 and 7 merged together, so you can look it out as a reference. Remember to support me with my annoying ads

Hi all, somebody was kind enough to supply his fix to the problem. It is indeed strange that I did not noticed that this problem disapeared while implementing the navmesh in chapter 6 of the UDK tutorial. By setting the collision cylinder, it seems the character now falls to the ground. I suspect that without this object property, there is simply no physics applied to the character each frame. I may be wrong like always we are on a course to truth anyhow. Get the fix at the end of the page here.
I have splitted a tutorial I am working on. Its about implementing navmeshes and doing some basic squad following a leader (playercontroller). I will be adding chapter 7 probably this week since I will be after most of my mid-term exams. I am thinking about changing the layout of the website as it is difficult to find the tutorial pages directly. I will probably split the website into two section, one for the wordpress blog and another for all the tutorials. I will also be working to fix some issues with the blog itself and maybe open some sort of small forum for questions although I like the fact that people can get hint in the UDK forums. I am also planning to do a small section on Ogre3d. I have been playing with the squirrel language and am trying really hard to make the eclipse debugger work. I have been inspired at some level by Unity3d and would like to try to match its editor in some way. I envision also having multiple user connect to a scene and work on it in real time, it will probably be my school final project (thinking 3 years ahead). I know all these are available at some level when working on MMO’s, but what about not working on a MMO, no such open source project that I know of exist like that.
So anyhow, you can check the new chapter 6 of the UDK tutorial. It expands on the chapter 5 code. It may contain some errors and I do want you to understand the theory more than simply copy/paste, after the 5 first chapter, you should be able to make it happen by yourselves. Send me corrections if there is something bad, I will correct it asap.
Enjoy my blog and please click on my sponsors to motivate me more for tutorials, at any rate I might be able to buy myself a beer after a successful tutorial LOL !
Chapter 6 tutorial
Congratulation to Jeremy Stieglitz for his release of Dungeon Defense. You can get the the official release page here at UDK.com
The full source code to the project is available at UDK.com and you can jump to the developper’s blog on the forum :

From the source code I can definitely say that this will have a huge impact on learning how UDK works and should be coded. The Unreal tournament was kind of hard to follow for a beginner and Epic has also stated that they will offer smaller helping game with less source code for helping indie studios get off the ground. Hopefully the new Mastering Unreal book targeting Unreal Script will help understand most of the code behind DunDef.
Happy coding everybody, I know I will sink my teeth into that thing right away !
