well I want my character to jump when i press spacebar, but it doesn’t work.

```auto
void keyPressed(){
//i'd like to detect when space bar is pressed.

if(key==' '){}

//it did'nt work though :(

}

```

i saw (key==’ ') in other codes, but it doesn’t work for me.  
thanks ! 😁

</div>

this works:

```auto

boolean check = false; 

void draw() {
  if (check) {
    println("1");
  }
}

void keyPressed() {
  //i'd like to detect when space bar is pressed.

  if (key==' ') {

    check = true;
    //
  }//if
  //
}//func

```

Hello,

```auto
int value = 0;

void draw() 
  {
  fill(value);
  rect(25, 25, 50, 50);
  }

void keyPressed() 
  {
  //if (key == 32)
  if (key == ' ') //same as above
    {
    println("space");
    } 
  else 
    {
     //if (key == 10);
     if (key == '\n'); //same as above
     println("line feed");
    }
  }

```

You may have to pass a variable to draw() as in the keyPressed() reference.
