How make player rotate in jump function?

[angelkom]

How can I make the player rotate in jump function i'm using flying dog demo, the player doesn't jump if I put in jump function, but if I put in update function it rotates but I want to rotate only when he jumps I tried with this.sprite.rotation = -1, this.sprite.rotate, this.body.rotation, this.body.rotate, this.sprite.angle, this.body.angle but no luck

This should do it: 

this.sprite.rotation = 0.4;

[angelkom]

jump: function() {

         this.sprite.rotation = -0.4;

        if(this.body.position.y < 0) return;

        this.body.velocity.y = this.jumpPower;

        game.sound.playSound('jump');

    }

 

it doesn't work

Well of course id doesn't work because you have to check wether the player is jumping or not with a boolean variable.
But I do this in another way:

In the update function of the player I check if it's body's y velocity is <0 (going up) or >0 (going down) and then I adjust it's sprite rotation.

 

if(this.body.velocity.y < 0){  this.sprite.rotation = -0.4;}else{  this.sprite.rotation = 0;}

Since the rotation is immediate I would suggest to lerp the rotation.

Yes I fix that I remembered about the velocity thing thanks anyway
