Here is my full code of the example. 

https://jsfiddle.net/8ytsozsm/1/

I would like to create a platformer game and make the player has crouch function

but It has a problem , When I click the down button  to resize the sprite to achieve  "crouch"

 if (cursors.down.isDown) {
                 
        player.body.setSize(60, 89, 0, 0);    
        } else{
        player.body.setSize(60, 130, 0, 0); 
       
        }

the sprite is resize from from bottom to top, but I hope the sprite can resize from the top , how to do it with out player.scale.y = -1;

player.scale.y = -1;
this code can solve my problem, but Is there any other better way to do it?

thank you so much, thx

var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create, update: update ,render: render});

        } else{
        player.body.setSize(60, 130, 0, 0); 
       
        }
}

function render () {

game.debug.body(player);
    }

Hi @khleug35 ,

You have to change the vertical offset.

Replace this line:

player.body.setSize(60, 89, 0, 0);

with this:

player.body.setSize(60, 89, 0, 41); 

41 = 130 - 89.

 

Regards.

OH!!!!!Many Thanks

It is very simple way to solve my problem

I am sorry that I am so stupid....

thank you very much
