Constructor parameter issues

Using Arduino Programming Questions

This is what I have changed it to and now it doesn't work at all.
.h

class Relay
{
  public:
    Relay(int pin, bool kind); //kind 1 is positive on kind 2 is negative on
    void begin();
    void on();
    void off();
    int pin;
    bool kind;
  private:
    
};

.cpp

Relay::Relay(int pin, bool kind)
{
}

void Relay::begin(){
pinMode(pin, OUTPUT);
}

void Relay::on(){
if (kind=true){
digitalWrite(pin, HIGH);
}
else if (kind=false) {
  digitalWrite(pin, LOW);
  }

}

void Relay::off(){
if (kind=true) {
  digitalWrite(pin, LOW);
  }
else if (kind=false){
digitalWrite(pin, HIGH);
}

}
