Screen effects and how to use them?

[Cypher]

Ok, so as i have been progressing on my awesomely awesome map, ive started to get mappers block and have run out of ideas for rooms, well, for whats in the grasp of hammer and my knowledge of it. now, when playing crazychickens bank_v2, i noticed that when it thundered the screen shook, i have 2 question:

1) how do you do that, and can its magnitude be increased?
2) Can i make it so a certain texture or overlay fills it (so for example could i make it blurry or have on of the overlays that you set in post processing in singleplayer.)

3) can i make it so it happens to the player in that specific room and not everyone, thats the most important thing.

Thank you in advance, and help would be apprecisted

I'm assuming that the screen shaking is caused by an env_shake. you can change the magnitude in the properties.

by "Thundered" do you mean that it just played the sound? Because that would be ambiant generic. and they're probably set up to an logic_counter.

I'm sorry, but i'm not experienced in the screen overlays, so i can't help you there.
