舞臺是固定大小的，所展示出的一面，世界是大小可設置的，甚至無限大的。      攝像機大小默認是世界大小，如果設置世界大小很大 攝像機就可以移動啦， 例子： ~~~ var play = function(game){ this.init=function(){} this.preload = function(){ var fj = game.add.image(0,0,'fj') fj.anchor = {x:0.5,y:0.5} //設置圖片錨點 } this.create = function(){ console.log('play') game.world.setBounds(0,0,2000,600)//設置是世界大小 參數 左上角xy坐標，寬高 } this.update = function(){ var keys = game.input.keyboard.createCursorKeys() if(keys.right.isDown){game.camera.x += 1} else if(keys.left.isDown){game.camera.x -= 1} else if(keys.down.isDown){game.camera.y += 1} else if(keys.up.isDown){game.camera.y -= 1} } this.render = function(){} } ~~~ 相機即可跟著鍵盤移動而移動啦 相機聚焦到某個物體 ~~~ var play = function(game){ this.init=function(){} this.preload = function(){ var fj = game.add.image(0,0,'fj') } this.create = function(){ console.log('play') game.world.setBounds(0,0,2000,600)//設置是世界大小 參數 左上角xy坐標，寬高 pig = game.add.image(200,300,'pig') pig.anchor.set(0.5,0.5) game.camera.focusOn(pig) //相機聚焦到小豬上 } this.update = function(){ var keys = game.input.keyboard.createCursorKeys() if(keys.right.isDown){game.camera.x += 1} else if(keys.left.isDown){game.camera.x -= 1} else if(keys.down.isDown){game.camera.y += 1} else if(keys.up.isDown){game.camera.y -= 1} } this.render = function(){} } ~~~  讓相機跟隨小豬移動` ~~~ game.camera.follow(pig) ~~~`
