Double Jump Phaser 3

[Adele]

Hi, I'm new to developing games with Phaser3. I am going crazy, for days I have been looking for a way to do a 'double jump'. and I can't ...
I found many questions similar to this one here, but none gave me a concrete solution ...

I would like the player to double jump if I double-click the 'up' cursor.

Please help me.

function update() {

 

 

if (cursors.left.isDown) {

player.setVelocityX(-130);

player.anims.play('left', true);

 

} else if (cursors.right.isDown) {

player.setVelocityX(130);

player.anims.play('right', true);

 

} else {

player.setVelocityX(0);

player.anims.play('idle', true);

}

 

if (cursors.up.isDown && player.body.touching.down) {

layer.setVelocityY('100');

}

 

}

Hi @Adele welcome to html5gamedevs ?. Without seeing the context of your code I cannot help that much. But, I will give it a try. This is how I would implement a double jump on my game.

// create a variable canDoubleJump

function update() {
    
    if (this.keys.left.isDown) {
      this.body.setAccelerationX(-1000);
      player.anims.play('left',true);
    } else if (this.keys.right.isDown) {
      player.body.setAccelerationX(1000);
      player.anims.play('right',true);
    } else {
      player.anims.play('idle',true);
      player.body.setAccelerationX(0);
    }

    const didPressJump = Phaser.Input.Keyboard.JustDown(this.keys.up);

    // player can only double jump if the player just jumped
    if (didPressJump) {
      if (player.body.onFloor()) {
        // player can only double jump if it is on the floor
        this.canDoubleJump = true;
        player.body.setVelocityY(-100);
      } else if (this.canDoubleJump) {
        // player can only jump 2x (double jump)
        this.canDoubleJump = false;
        player.body.setVelocityY(-100);
      }
    }

}

The answer from @geocine should solve this just fine ?

Here's another solution that can be used to implement triple, quadruple, etc jump as well (if so desired ?)

This is a video of me implementing it in real time:
