Convert int to bit (but not as string)?

Questions & Answers
1

int Fire = 1;
int Rock = 2;
int Wind = 3;

  string strFire = System.Convert.ToString(Fire, 2);
  string strRock = System.Convert.ToString(Rock , 2);
 
  int combo1 = strFire | strRock ; 
  int combo2 = strRock | strFire ;  
  int combo3 = strFire | strFire ;

Hi, I’m trying to convert Fire and Rock integers into bits, so I can use bit operators on them. But I don’t know how. I’m still trying to find an answer on Google right now, but if anyone know the answer to this that would be very helpful :slight_smile:

You don’t need to convert to string, you can use the operators directly on integers (or other integral types).

That’s not true. As your fire is 1, fire|fire will give 1.
Also if you are going to use bitwise operators it’s better to use powers of 2:

int Fire = 1; //0001
int Rock = 2; //0010
int Wind = 4; //0100
int Earth = 8; //1000

When you work with powers of 2 every OR operation on 2 items will give a distinct answer.
Fire|Earth for instance will be 9.
while Earth|Earth will be 8.

You should not need any string operations.

I read your other question (which is basically a duplicate now), if you want to check whether slot1 and slot2 have a combination of Rock and Wind you would just do:

int combination = slot1value | slot2value;
if (combination == 3)
    //Fire + Rock
else if (combination == 5)
    //Fire + Wind
else if (combination == 6)
    //Wind + Rock
else if (combination == 9)
    //Fire + Earth
else if (combination == 10)
    //Rock + Earth
else if (combination == 12)
    //Wind + Earth
