Hey, guys! I find it annoying that flashbang is so bright. Is there a way to make it black, grey... Thanks for your time! (Becoming blind in real life is not an option... )

No, you can't.

It's a really good suggestion for update.

Some people cannot bright flashes of light, it's a really good accessibility option.

Turn off your monitor before the flash, turn on again after the flash efect is gone. Boom you got a life hack here .

Just play with sunglasses like pros.

I like your answer the most, bro. I've decided to go even further and switch off the entire city's electricity supply and when flashbang's duration is over, switch it on again...

I think a LUA script can help.
One, where you dont throw actual flashbangs but use zombie claws or smiliar to fake the flashbang projectile. And then instead of flashing the player, the flash-affected player get an full-black HUD image for some time.

Btw, a HUD lua image gets covered by the vanilla flashbang so there is no easy way sadly.

You may use hacks such as anti-flash (no).

By the way is rather to add ability to check player(id,'flashed') or smth, in cases with cheats or whatsoever.

cs2d.com says:
ai_flash: how long (in seconds, float) is this bot flashed by a flashbang (0 for not flashed)

^ but bot's behavior is only caused by timer.

Real men increase the brightness of the flashbang instead.

As in this example on Youtube .

Now for real mabye you should adjust brightness and gamma, this is the "easy fix". Some monitors from zowie got nice features to see on dark spots and have low brightness at the same time.
