Single line if statement with many conditions or several single-conditioned if statements

Questions & Answers

I apologize that this is not exactly Unity related, but I could not find any information on this elsewhere.

I have been wondering for a long time now what is the best way to use if statements. You can see what I mean by that below.

A single line if statement(contains several conditions):

if(X && Y && W && Z && G){
    Execute();
}

And Many statements inside a statement.

if(X){
    if(Y){
        if(W){
            if(Z){
                if(G){
                    Execute();
                }
            }
        }
    }
}

In the end they all do the same thing I suppose, but obviously the first example looks a bit more neat than the latter, but are there any performance benefits(or any benefits for that matter) using either of these two examples?

Thank you,

Yours faithfully.

An if with multiple parts separated by && or || only evaluates subsequent terms if it needs to - so there is no performance difference and they are equivalent.

i.e. X && Y only checks Y if X is true.
X || Y only checks Y if X is false

I would strongly counsel against anything that had that much indentation - you’ll tie yourself in knots trying to work out what is going on.
