Question by bpears · Apr 11, 2015 at 03:33 AM · intif

Right way to use multiple "or" withinin "if" statement?

Is this the correct way to use several "or" within a if statement?

 private var someint
 private var otherint
 
 function Update{
 
     if(someint == ((otherint+1)||(otherint+2)||(otherint+3))){
         //do stuff
     }
 
 }


Im mostly not sure about if I am using parenthesis right in order to compare each of the 3 calculated ints separate from each other.

In C# this syntax will give a compile error because the conditional operators ( && and ||) don't work with ints. Unityscript/js compiles this because it's a less strongly typed language that allows implicit conversion of int to boolean, where any number not 0 or NaN means TRUE.

Consider your clause:

 ((otherint+1)||(otherint+2)||(otherint+3))

This will return the first non-zero number of the three. Then you compare someint to it, meaning you are only comparing someint one of your numbers (the first if otherint is not -1, the second otherwise). So for the most part your IF clause will be true if someint == otherint+1.

Assuming you want to "do stuff" if someint is equal to any of the three values do this:

 if ((someint == otherint+1) || (someint == otherint+2) || (someint == otherint+3))

Or more efficiently in this case because you have a range of integral values:

 if ((someint >= otherint+1) && (someint <= otherint+3))

|| is mostly used to combine bools, i.e.

 bool temp1;
 bool temp2;
 bool temp3=temp1||temp2;

In your case you would do something like

 if((someint == otherint+1)||(someint==otherint+2)||(someint==otherint+3))){
      //do stuff
 }
