Hi, i am a newbie in using Phaser and i am trying to figure out how i can add the space bar as key for "upwars" Therefore i was looking at phaser.js how createCursors() is realized and tried to enhance it like this cursors = game.input.keyboard.createCursorKeys(); cursors2 = game.input.keyboard.addKeys('up', Phaser.Keyboard.SPACEBAR); but using it like cursors2 = game.input.keyboard.addKeys('up', Phaser.Keyboard.SPACEBAR); i get the error: Unable to get property 'isDown' of undefined or null reference Has anybody a hint how to solve that?
