Hi Niko:
When u design the irrlicht engine, do u use the UML to analyze and
design or have the different way??

Hi, mostly I just think about the interface of classes how they should be if I would have to use them. I implement them, try them out, change things I did not like, try them out again and so on. For complex things I also use UML sometimes, but not all the time.

Do you write testcases upfront?

No real test cases, but I simply have about 10 test applications, which use most features of the engine. I usually compile and run them before makeing a release, checking if everything still works. But the engine is getting bigger and more and more complex, I should consider start using unit tests.

Hi Niko:
Thanks to replay my question.When u star to design the your Engine,
do u draw the architecture or just think? Do u will to see the other source code or just code by yourself?

i sorry my english,

Mostly I just think, but if it is getting to complex, I also draw.

And sure, sometime before creating an interface for new features, I have a brief look on how other engines did this before.

What other engines do you look at? How do they compare to Irrlicht engine?

Another question: What does Irrlicht stand for?

Thanks

Oh, man. Take it from me, as soon as you have a wife (and especially a baby kid) your coding time gets cut down to nothing. I have to sneak out when they are both sleeping to get any code done.

Don't believe me? I'm typing this at 1:40 am after a hard day's work...

Hi niko:
When i finished the book about Design Patterns,
I had some questions. Do u using the Design Patterns in your engine ?

ps sorry for my poor english

Sure, not extensively, but they are in there. Just take a closer look at the internals of the SceneManager and the GUIEnvironment for example.
