6 LEDs have to blink, after a button is pushed, but not held

Using Arduino LEDs and Multiplexing

Hi there!

Im working on a script, that activates 6 leds, after pushing, but not holding the button. When i push the button again, it has to stop. This is the code i got:

int ledPin[] = {4,5,6,7,8,9};
int ButtonPin = 13;
int state = 0;

void setup() {
  pinMode(ledPin[0],OUTPUT);
  pinMode(ledPin[1],OUTPUT);
  pinMode(ledPin[2],OUTPUT);
  pinMode(ledPin[3],OUTPUT);
  pinMode(ledPin[4],OUTPUT);
  pinMode(ledPin[5],OUTPUT);
  pinMode(ButtonPin,INPUT);  
  }

void loop(){
  state = digitalRead(ButtonPin);
    if (state==LOW){
      digitalWrite(ledPin[0],HIGH);
      delay(250);
      digitalWrite(ledPin[0],LOW);
      digitalWrite(ledPin[1],HIGH);
      delay(250);
      digitalWrite(ledPin[1],LOW);
      digitalWrite(ledPin[2],HIGH);
      delay(250);
      digitalWrite(ledPin[2],LOW);
      digitalWrite(ledPin[3],HIGH);
      delay(250);
      digitalWrite(ledPin[3],LOW);
      digitalWrite(ledPin[4],HIGH);
      delay(250);
      digitalWrite(ledPin[4],LOW);
      digitalWrite(ledPin[5],HIGH);
      delay(250);
      digitalWrite(ledPin[5],LOW);
    }
  }

  /*else
  {
  digitalWrite(ledPin[0],LOW);
  digitalWrite(ledPin[1],LOW);
  digitalWrite(ledPin[2],LOW);
  digitalWrite(ledPin[3],LOW);
  digitalWrite(ledPin[4],LOW);
  digitalWrite(ledPin[5],LOW);
  }

Thanks for your help!

The IDE has a section under "File" called "Examples".
Look for the state change detection example, and work from there.
