[P2] Rotation and anchor point

[titmael]

Hi,

 

here is my Weapon "class" :

function Weapon(game, x, y, sprite, hero){    Phaser.Sprite.call(this, game, x, y, sprite);    this.anchor.setTo(.5, 1);    this.game.physics.p2.enable(this, true);    this.body.motionState = Phaser.Physics.P2.Body.KINEMATIC;    this.using = false;    this.hero = hero;}Weapon.prototype = Object.create(Phaser.Sprite.prototype);Weapon.prototype.constructor = Weapon;

I don't get why when I rotate it with

this.body.angle -= 0.1;

the sprite rotate from it's middle and not from (0.5, 1) anchor point ?

 

Any ideas ?

Enabling P2 resets the anchor to 0.5, 0.5. Try setting your anchor after enabling physics, though I think there may be a specific reason why P2 needs it to be centered.

Ok maybe there is another way to redefined the anchor properly for the sprite and P2 body ?

[lewster32]

Maybe add the hammer to a group and offset it in the group, then rotate the group?

Here is what happens when I move "this.anchor.setTo(.5, 1);" after P2 init (the debug body is hammer's)

Came up with this :

this.game.physics.p2.enable(this, true);this.anchor.setTo(.5, 1);this.body.clearShapes();this.body.addRectangle(29, 52, 0, -26);this.body.updateCollisionMask();
