P2JS shoot the pointer

[przemoo83]

Is there any easy way to achieve this effect in P2? Something similar to moveToPointer() in arcade?

[spiritabsolute]

I was also interested in it!
I was beginning to wonder why I use P2JS?  

How to understand whether I need P2JS. It may be better to use arcade?

Arcade is faster. If you need better performance (maybe for mobile, old computers or very complex games) stay with arcade (in good computers and/or in simple games you dont will feel any difference). But, arcade works only with rectangles so, if you need to collide with balls or something complexer you possible will dont have a good effect with arcade.

I have a simple game made with P2JS and an older version made with arcade, you can see the difference between the ball collision with the basket.

I changed my P2JS code to make it have a similar effect as moveToPointer() example (http://phaser.io/examples/v2/arcade-physics/move-to-pointer).

You can see it running here (http://funs2.com/funs2/games/pointer_example/).

create : function()
    {   
        this.canmove=false;
        this.baskball = this.game.add.sprite(this.game.world.centerX,this.game.world.centerY+(this.game.world.centerY/2),'ball');
        this.game.physics.startSystem(Phaser.Physics.P2JS);
        this.game.physics.p2.gravity.y = 0;
        this.game.physics.p2.enable(this.baskball);
        this.baskball.body.setCircle(30);
        this.baskball.anchor.setTo(0.5, 0.5); 
        this.baskball.body.moves = false;
        this.baskball.body.allowGravity = false;
        this.baskball.body.static = true;
        this.input.onDown.add(this.move, this);
    },
    
    move : function() {
        this.baskball.body.velocity.x=this.game.input.activePointer.worldX-this.baskball.x;
        this.baskball.body.velocity.y=this.game.input.activePointer.worldY-this.baskball.y;
        this.canmove = true;
    },

    update : function()
    {
        if (this.canmove == true)
        {
            this.baskball.x = this.game.input.activePointer.worldX;   
            this.baskball.y = this.game.input.activePointer.worldY;
        }
    }
