Can't jump

[hotgeart]

Hi,

Sorry for my bad english.

I'm new in the world of html5 game and I'm trying to follow the tutorial from the book. I've an issue, I can't jump. I've no idea why.

A link for testing : http://not more online

If you look at the console, it's detecting the key up and if the player is touching the floor. But not the "JUMP!" and the velocity Y of course.

The code ( from : http://not more online ) :

Line 57if (this.cursor.up.isDown && this.player.body.touching.down) {    console.log('JUMP!');    this.player.body.velocity.y = -320;}

Thanks for your help.

You need to add  "this.cursor = this.input.keyboard.createCursorKeys();" in the create-function or "this.cursor" will be undefined.

Cursor is defined, I can move the player but the jump doesn't work.

Could you try changing " this.player.body.touching.down " in your UP key check with "this.player.body.blocked.down" ?

Change:

    update: function() {        this.movePlayer();        game.physics.arcade.collide(this.player, this.walls);

to:

    update: function() {        game.physics.arcade.collide(this.player, this.walls);        this.movePlayer();

Ok it's work. Can you explain the problem ?

 

thx

You were checking this.player.body.touching.down before you called the Arcade Physics collide() method, thus it was always false when you checked it in your jumping code. Until you call collide() the Player object's body is not tested for touching anything...

[j0hnskot]

This is because each frame the touching object gets reset to false. You were checking if the player is touching down before physics did the check for that, resulting to  false.
