You know Cold Stream, the part where you open the cellar door? I think it's in the first chapter.

I am wondering how to make an event like that where you download code on a computer(in the game! lol) to unlock a blast door to the saferoom. Any help would be useful, thanks.

It was a bunker.-Ren

Func_button, func_movelinear and some props is all you'd need.

How do you get the scavenge-style fill up meter with different text?

Func_button_timed

Ok thank you, it works very well.

I have another problem. My info_changelevel brush disappears in-game and I've tried everything. It's at the end of the level.

Disappears how? It should be invisible in-game. How are you checking if its there or not?

It may be there, but the navigational mesh can't find it. It's making my mesh broken and closing the saferoom door doesn't do anything.

It has to be snapped to the floor and be tied to an info_landmark. Are you in NAV mode when you test it? (Is the bright blue text showing up in the console when you're in the SR and the door is closed saying "Would change level... but not going to!" ?)

Ok, Nav flow now works!

But one question: How do you make a setup where there are 5 button press events leading up to the opening of 2 doors?

Example: Press 5 buttons in any order and then something happens.

EDIT: Nevermind, I got it using the mathcounter.
