Efficiency of IF statements - Bharel - 19.06.2013

My question is a bit theoretical. What would be more efficient?
Using "if (bool:usuallyfalse && GetPVarInt(playerid, "bar") > 0)"
or

Код:

if (bool:usuallyfalse){
if(GetPVarInt(playerid, "bar") > 0){

Does an IF statement, check both statements when called? or does it check one after the other?
If it checks both, the second version will be more efficient. If it checks one after the other, the first version will be.

You're looking in wrong places to optimize code. As for your question, try looking through pawn-lang.pdf. I think it has a section on it.

pawn Код:

if (usuallyfalse && GetPVarInt(playerid, "bar"))

That checks if usuallyfalse is true, and if it is true, it will execute the next statement and so on.

Why is that? Let's say the code is in a loop, OnPlayerUpdate, or OnPlayerTakeDamage, it's really important even in the tiny bit.

So as soon as usuallyfalse is false, and it gets to the && part, it stops executing, without checking the next statement?

Yes, try this:

Код:

if( 1 == 0 && print( "Hey" ) == 0 )
{
    print( "Hi !" );
}
