call function from scene

[jimmy008002]

Hi, I am a beginner, I want to call the function outside the scene, is it possible?
For example,

k.scene("game", () => {

function jump() {
if (player.isGrounded()) {
player.jump(JUMP_FORCE);
console.log("sdasdsdasdasdaaaaaaaaaaaaaaaaaaaaaaaa")
}
}

  // jump when user press space
  k.onKeyPress("space", jump);
  k.onClick(jump);

});

I want to use jump() outside the scene to control the character in-game scene. How can I do it?
Thx

Actually, I am doing pose detection to control a game character, but putting everything on one web page include cam, game, detection is out of memory, I can fix it by setting the game size to 360 x 240, otherwise it will stop working, but i need to tackle the problem of controlling first.

Hi!! Welcome to kaboom. You can define your function in the top of your file

kaboom();

function jump(player, JUMP_FORCE) {
   if (player.isGrounded()) {
      player.jump(JUMP_FORCE);
      console.log("sdasdsdasdasdaaaaaaaaaaaaaaaaaaaaaaaa");
   }
}

scene("start", () => {
    const player = add([]);
    jump(player);
});

scene("end", () => {
    const player = add([]);
    jump(player);
});

Hi thank you so much for answering me!

` k.scene("game", () => {

  // define gravity
  k.gravity(2400);

  // add a game object to screen
  const player = k.add([
      // list of components
      k.sprite("bean"),
      k.pos(80, 40),
      k.area(),
      k.body(),
  ]);

  // floor
  k.add([
    k.rect(k.width(), FLOOR_HEIGHT),
    k.outline(4),
    k.pos(0, k.height()),
    k.origin("botleft"),
    k.area(),
    k.solid(),
    k.color(127, 200, 255),
  ]);

   var jump=function() {
      if (player.isGrounded()) {
          player.jump(JUMP_FORCE);
         
      }
  }

  // jump when user press space
  k.onKeyPress("space", jump);
  k.onClick(jump);

  function spawnTree() {

      // add tree obj
      k.add([
        k.rect(48, k.rand(32, 96)),
        k.area(),
        k.outline(4),
        k.pos(k.width(), k.height() - FLOOR_HEIGHT),
        k.origin("botleft"),
        k.color(255, 180, 255),
        k.move(k.LEFT, SPEED),
          "tree",
      ]);

      // wait a random amount of time to spawn next tree
      k.wait(k.rand(0.5, 1.5), spawnTree);

  }

  // start spawning trees
  spawnTree();

  // lose if player collides with any game obj with tag "tree"
  player.onCollide("tree", () => {
      // go to "lose" scene and pass the score
      k.go("lose", score);
      k.burp();
      k.addKaboom(player.pos);
  });

  // keep track of score
  let score = 0;

  const scoreLabel = k.add([
    k.text(score),
    k.pos(24, 24),
  ]);

  // increment score every frame
  k.onUpdate(() => {
      score++;
      scoreLabel.text = score;
  });


  
  
}
);

function jump(player,JUMP_FORCE) {
  if (player.isGrounded()) {
      player.jump(JUMP_FORCE);
     
  }

}

jump();`

now the problem is Cannot read properties of undefined (reading 'isGrounded') , I try to code in react, is it the reason I need to declare k in front of function?

yeah u need set the player parameter in your function I think
