ep8 What is a Quaternion? Unity3D Game Design Tutorial

Quaternions are like vector3's, but instead of a position in 3D space, it saves a rotation in 3D space.

@ETeeskiTutorials Your videos made me finally get it.. The result is my first game in Unity3D! :D It's called Pong Unleashed, and you can find a video of it along with a download link here on YouTube.. I won't post the link in this comment because I don't want to spam.

@robbit10 I just checked out your game. It's pretty awesome. especially for your first game. Just out of curiosity, where did you use quaternions in your game? the shaking letters?

Nice job--thanks for the explanation. Hope your thumb is okay!

[ETeeskiTutorials]

@jeffssmith1 haha well now that i use a green screen instead of a little kid's whiteboard, my thumb shouldn't get any more injuries.

thanks for the video! learning all the time!

[ETeeskiTutorials]

@Narlynarz Thanks man, it's good to know there's someone out there making use of these videos. lol.

@ETeeskiTutorials Thanks! Actually, the final product doesn't have any quaternion transformations in it.. I made the shaking letters with Transform.position, and the letters that rock back and forth or from left to right were done with the Animation tool. Still, a part of your entire video series (not just this video) made me get it and then I got to work and referred to the scripting reference and help on IRC (freenode.org, #unity3d) for further learning ^^

Cool video - thanks for posting this!

Euler angles are pronounced Oiler due to them been named after Leonhard Euler so the English language isn't really to blame :D

I'm having so much trouble figuring out what a quaternion is but I think this helped. I definitely learned what a euler angle is though haha.

[Gunslingerssong]

good stuff man, keep it up! I hope you show case some examples on how to use Quaternions

[8RosaTeam]

lol. Good tutorials! Your digital-lastgeneration-blackbo­ard is awesome! ;-)

Really, this kind of tutorials are very helpful to understand some 3D concepts.

Greetings.

@ETeeskiTutorials you just need the right exposure to get that hit count running! good job.
