Hi, I'm using a group for all bullets in the game, and would like to keep the bullets of enemies in subgroups of the main bulletgroup. For some reason, this code crashes, and I can't figure out why. The error I get: Uncaught TypeError: Cannot read property 'x' of undefined phaser.js:34380 this.bullets = this.game.add.group(); var enemyBullets = this.game.add.group(); enemyBullets.createMultiple(30, 'arrow'); enemyBullets.setAll('anchor.x', 0.5); enemyBullets.setAll('anchor.y', 0.5); enemyBullets.setAll('outOfBoundsKill', true); this.bullets.add(enemyBullets); this.game.physics.enable(enemyBullets, Phaser.Physics.ARCADE);
