Henry Leinen
For the last year, Henry Leinen has been working tirelessly on creating a level editor for Aliens vs. Predator. He runs his own software company, and is trying to get his PhD. Now no longer a member of the PREditor team, he and his brother Chris are now making their tools for themselves, and for the AvP community.
Henry Leinen - It all started last summer when Tom Crosswell asked my brother Chris if we would be interested in joining the PREditor team.
Henry Leinen - Because it was a challenge for me to work with an international team, and to do some research on the the internals of a game like AvP.
Henry Leinen - Well actually it was me starting to work on the level editor itself. Some time later Chris started to write some components for the level editor.
Planet AvP - When you say there was no information about AvP's level internals, what do you mean? Can you elaborate?
Henry Leinen -There was no information about how the levels were stored and what kind of components the game uses. At that time we didn't actually know if it would be possible to use or create runtime components. Now we know that it's not possible by the way.
Planet AvP - Because of the lack of information on how the levels where created?
Henry Leinen - It would have helped a lot if we had the source code OR some information.
Henry Leinen - It was really tough, because we couldn't even just access any of the level data. Most of them are compressed in a non-standard way.
Henry Leinen - Have you ever had a look at a binary file? Well, there are so many numbers! And that was the problem: Arrange these numbers and see if you can get any useful 3D scene information out of it :).
Planet AvP - So, it was basically trial and error?
Henry Leinen - Yes, something like that.
Planet AvP - Is that still occuring now?
Henry Leinen - No. One fine day, we got some information about at least a few items. I had decoded most of them till then, but anyway, a little help is much better than nothing :). But yes, I'm still decoding stuff!
Planet AvP - What do you think Rebellion of done to help you out?
Henry Leinen - First of all, they could have helped us a lot, sending some detailed inforatmion about how things are stored in different files.
Henry Leinen - Saying that only C++ programmers can use such a complex level editor implies that the existing AvP levels were done by C++ programmers, right?
Henry Leinen - We have just made some major progress with importing 3D Studio Max created scenes and objects. So you should expect the next version to be released next week.
Planet AvP - Will other studios such as Paint Shop Pro and MilkShape by be supported?
Henry Leinen - For the beta cycle, no.
Henry Leinen - Yes.
Henry Leinen - It will definitely speed up the development, and it will certainly give the Level Editor more features. But Chris and I are responsible for the stability, because this is only a matter of programming, if more people would download the beta, try out everything, and then report to us what they found. It would also be better if we could get some hint of what could be done better or what isn't really needed, because Chris and I are not 3D artists.
Planet AvP - When can we expect the final release of the PREditor?
Henry Leinen - That strongly depends on how fast we can decode the remaining details of AvP levels.
Henry Leinen - The only way to run single player levels is to replace existing levels.
Henry Leinen - Currently I am developing AvP related tools. But most of the time I'm actually doing something completely different.
Henry Leinen - I am currently working on my PhD at the University of Bonn.
Planet AvP - What are you getting a PhD in?
Henry Leinen - I'm working as a physicist and I'm currently trying to get my PhD in Physics.
Planet AvP - What is your favorite game?
Henry Leinen - Oh, I hope not too many people will hate me for this, it's Microsoft's Flight Simulator. I love flight simulators!
Planet AvP - What is your goal in life?
Henry Leinen - Several things, but the most important ones are to always be able to enjoy life as it is and maybe getting some more money sooner or later :).
