How to implement the sequence in this code, using 5 shift register?

int latchPin = 8;

int clockPin = 12;

int dataPin = 11;

byte leds;

boolean trig = true;

unsigned char type;

void setup() {

//set pins to output so you can control the shift register

pinMode(latchPin, OUTPUT);

pinMode(clockPin, OUTPUT);

pinMode(dataPin, OUTPUT);

}

void loop(){

if(trig){ type = LSBFIRST;}

else{ type = MSBFIRST;}

chaser();

trig = !trig;

//change the value of the boolean to control LEDs using a different bit order each run

}

void updateShiftRegister()

{

digitalWrite(latchPin, LOW);

shiftOut(dataPin, clockPin, type, leds);

digitalWrite(latchPin, HIGH);

}

void chaser(){

leds = 0;

for(int i = 0; i <8;i++){

bitSet(leds,i);

if(i!=0){bitClear(leds,i-1);}

updateShiftRegister();

delay(100);

}

}
