So i'm relatively new to JS and Phaser. I'm using yeoman to scaffold phaser and it is all working fine...except for global variables. I'm too new to coding in general to bend everything to my will. the issue i'm having is trying to get a prefab to talk to the 'play' state. I have a function inside my prefab: var destroyBacon = function() { this.destroy(); this.game.score += 1;}; the 'this.destroy();' works perfectly. but I want for every time I use that function (which is every time I click a sprite from that prefab) to add a point to the 'score'. I get this every time: Uncaught TypeError: Cannot read property 'score' of null I'm not sure if I should even be using the 'this.game.' or where I should put the actual score variable. Ideally, I'd like each of my prefabs (of sprites) to add to the score. any advice would definitely help.
