Does anyone know why I can't get the bullet coming from megaman's arm to continue going after i left go of the mouse button? I tried using mouseclicked() but it only showed the bullet at the starting point and it would soon after disappear. Also, Is there a way to keep sending out bullets? At the moment, I can only shoot once per run and every time i press down on the mouse button, it shows the bullet where i let go of the mouse button. Any tips? Thanks in advance for your help!

PImage megaman1;
PImage megaman2;
int x=0;

void setup() {
  size(800, 315);
  megaman1 = loadImage("megaman1.png");
}

void draw() {
  background(255);
  image(megaman1,0,0);
 
  if (mousePressed == true) {
    megaman2 = loadImage("megaman2.png");
    image(megaman2,0,0);

    fill(251, 255, 44);
    noStroke();
    rect(400+x,143, 50, 20);
    x=x+10;
  }
}
