WHAT IS NO_FOW?

RAVENOUS:whoa, thanks RAVENOUS!      , you dont need to make little video or some pictures.

um, how do i make a 2 floors house?

Nice way to help people with their mapping questions, because once you know the mapping possibilities, you can use your imagination to make a new feature

An example:
if you destroy a env_breakable you can trigger something like a door, but the question is:
What do you do to make 2 breakables open 1 door? (I mean, in game you need to destroy both breakables to open the door, you can destroy them in any order)

I already know a possible answer to this problem (if there is another way), but I want to know if anyone else can solve it.

I've tried that many times, but now I see Gamemaster2's answer I know how you do it

Ive also tried it many times and didnt know wether this idea works or not...
But i tested it and it works!!!

You're great
Now I can finish my cracked EDVK version

When I was making EDVK I did that (but with breakables), I mean, a 100 hp breakable broken with two 50 (half) power explosion damage of other two breakables, but didn't worked

The reason, the explosion damage decreases with distance, so, the explosion did a 49 or 48 of damage, 2 explosions of that power weren't enough

if you want to make a 2 breakable switch use the 90% of the main breakable's health as both explosions power

the 50% power is great to make a 3 breakable switch since:

(50% - 1% distance reduction)*3 > 100%

Okay, so now I know all your secrets.
