In the case of this function, or any other like it:

Код:

if(!IsPlayerConnected(userid))

What does the ! in it do?

[xser12]

if(!IsPlayerConnected(userid)) - would be if player isn't connected.

! means the word "not", or can be compared to the English word "opposite". Let's say you have a boolean that is true. If you do ! in front of it it means it's false:

Код:

bool x = true;

while(!x) //while x is not true, aka while x is false
{
}

Basically will turn anything into the opposite:

Код:

int x;
if(!(x < 10)) //means the opposite of if x is smaller than 10, = x is bigger than 10

if(x != 10) //if x is not 10
//or
if(!(x == 10)) //would do the same thing but != is much easier to write

The "!" indicates the oppositional value of that function, in this case if the statement is 1, it will check the opposite (0).

Hansrutger explained it perfectly.
