Hi everyone, I’m having trouble with shooting another bullet only when the previous bullet fired is off the screen. This is my current code.

```auto

```

int x = 30;  
int y = 60;  
float gunX = x+20;  
float gunY = y+20;  
float circleY;  
float circleX;  
boolean bulletFlies=false;  
float bulletX = 20;  
float bulletY = 20;

void setup() {  
size(500, 500);  
circleY = random(25,480);  
circleX = 450;  
}

void draw() {  
background(0);  
fill(255, 56, 99);  
ellipse(x, y, 60, 60);  
gunX = x+12;  
gunY = y;  
bullet();

fill(255);  
circle(circleX,circleY, 80);  
circleX=circleX-0.5;

}

void keyPressed() {  
if (key == ‘s’) y = y + 8;  
else if (key == ‘w’) y = y - 8;  
else if (key == ’ ') {  
bulletFlies=true;  
bulletX = gunX+14;  
bulletY = gunY+4;  
}  
}

void bullet() {  
if (bulletFlies) {  
ellipse(bulletX, bulletY, 6, 6);  
bulletX = bulletX+5;  
if (bulletX\>width+12) {  
bulletFlies=false;  
}else if (key == ’ ’ && !bulletFlies){  
}  
}  
}

```auto

```

this would be enough:

just check if the bulletFlies and if so, leave

```auto
  else if (key == ' ') {
    if (bulletFlies)
      return; // leave
    bulletFlies=true;
    bulletX = gunX+14;
    bulletY = gunY+4;
  }

```
