Group.callAll() kills game

[bborncr]

I am trying to adjust the physics body size of some bullets.

bullets.createMultiple(20, 'bullet');
bullets.setAll('anchor.x', 0.5);
bullets.setAll('anchor.y', 0.5);
bullets.setAll('scale.x', 0.3);
bullets.setAll('scale.y', 0.3);
bullets.setAll('bounce.x', .5);
bullets.setAll('bounce.y', .5);
bullets.setAll('mass', 0.05);
bullets.callAll('body.setSize',8,8,8,8); //this line kills the game

When I add the final line with the callAll() method the game won't start.

One example added two single quotes '' : bullets.callAll('body.setSize', '', 8,8,8,8);  

But that didn't work either.

createMultiple creates Phaser.Sprite objects, which do not have a physics body by default so 'body.setSize' is trying to call setSize on an undefined body. Unless you have set enableBody on the group first ? 'game won't start' and 'kills game' is not clear so I'm not sure, do you have any errors int he console ?

var bullets = this.game.add.group();
bullets.enableBody = true;

bullets.createMultiple ....
....
....

Also the callAll should look like (the second parameter is a string denoting the context the function should be called in; behind the scenes the group converts your '' to null anyway, setting it to null is just more clear: https://github.com/photonstorm/phaser/blob/v2.6.2/src/core/Group.js#L1561)

bullets.callAll('body.setSize', null, 8, 8, 8, 8);

Thanks for the help!

Yes, I do have the body enabled. When the game starts there is just a black screen. Below is the console error. If I comment out the callAll line the game runs.

bullets = game.add.group();
bullets.enableBody = true;
bullets.physicsBodyType = Phaser.Physics.ARCADE;

bullets.createMultiple(20, 'bullet');
bullets.setAll('anchor.x', 0.5);
bullets.setAll('anchor.y', 0.5);
bullets.setAll('scale.x', 0.3);
bullets.setAll('scale.y', 0.3);
bullets.setAll('bounce.x', .5);
bullets.setAll('bounce.y', .5);
bullets.setAll('mass', 0.05);
bullets.callAll('body.setSize',null, 8,8,8,8);

Ah, all you need to do is change the callAll to use the body as the context;

bullets.callAll('body.setSize', 'body', 8, 8, 8, 8);

That was it!! Thanks!
