Hello,
I want to have someone talk in my map, let's take GLaDOS for example. I see a list of sounds but they're not really informative - I can't be sure what are the exact words in each sound file. So, is there any project someone did to list them and type down the chatter?
Also, when doing a scene involving Wheatley, will he automatically play the correct animation (like the one in the game) or should I do it manually somehow?

Thanks!

As for Wheatley; you will have to do the animations yourself. Try decompiling the maps in which the lines you want are used for some help.

Thanks a lot, it will help me very much, and I'm sure it'll help more people too. Any chance you know the list of the Announcer's sound files and Cave Johnson's too?

It's linked to at the bottom of that page, if I recall correctly.

This is true, but here you go anyways.

I rely on those lists to pick the perfect dialogue for my maps. I've saved those links in my browser.
