The most basic approach is to have a player-object and add some properties on initGame. //in initGame if (!window.story.state.player||forceReset) { // storage of variables that doesnt fit player window.story.state.player = { health: 100, hasSword:0, //if the property equals 0 player has no sword hasPainkillers:0 //the property } }
