未定义Phaser//Javascript//Player

一切正常，除了更新功能，当我放回var播放器时，它无法识别：

未捕获引用错误：未定义播放器

我也不确定动画中的马里奥是否是玩家，这是马里奥的级别

这是我的密码：

var SandBox = {

    preload:function(){

        //this.game
        console.log("preload Sand Box");

        this.game.load.image('platform', 'assets/platform.png');
        this.game.load.spritesheet('mario', 'assets/mario.png', 32, 32 , 12);
        this.game.load.image('coinbox', 'assets/coinbox.png');
    },

    create:function(){
        console.log("create Sand Box");

        var imageHeight = this.game.cache.getImage("platform").height;
        this.game.physics.startSystem(Phaser.Physics.ARCADE);

        var worldHeight = this.game.world.height;


        var ground = this.game.add.sprite(0, worldHeight - imageHeight, 'platform');
        var platform = this.game.add.sprite(250, 285, 'platform');
        var platform = this.game.add.sprite(-250, 145, 'platform');
        var platform = this.game.add.sprite(280, 285, 'coinbox');
        var player = this.game.add.sprite(32, 100, 'mario');

        this.game.physics.enable(ground);
        this.game.physics.enable(platform);
        this.game.physics.arcade.enable(player);

        player.frame = 5;
        ground.body.immovable = true;
        platform.body.immovable = true;        
        player.body.bounce.y = 0.2;
        player.body.gravity.y = 300;
        player.body.collideWorldBounds = true;


        player.animations.add('left', [0, 1, 2, 3], 10, true);
        player.animations.add('right', [5, 6, 7, 8], 10, true);

    },

    update:function(){
        console.log("update Sand Box");
        this.game.physics.arcade.enable(player);

        var hitPlatform = this.game.physics.arcade.collide(player, ground); // << THESE FUNCTIONS
    }


}

代码段中的播放器是其所在函数的本地。将玩家的声明移出沙箱：

var player;
var sandbox = {
    create: function() {
         //... skipping lines ...
         player = this.game.add.sprite(32, 100, 'mario');
    }, 
    Update: function() {
          //use player here
          var hitPlatform = this.game.physics.arcade.collide(player, ground); // << THESE FUNCTIONS

    }
};

玩家不在范围内。在函数外声明它。对不起，我不知道如何在函数外声明它。你能告诉我该放哪条线吗？嘿！它正在工作，但还有另一个错误：UncaughtTypeError:无法读取undefinedokay的属性“hasOwnProperty”-我在代码中没有看到对该方法的任何调用，因此我怀疑它在Phaser代码中。。。这可能是您在单独的问题中提出的问题，除非您可以创建另一个示例，例如，在中，或者甚至是

 var sandbox = {
        create: function() {
             //... skipping lines ...
             this.player = this.game.add.sprite(32, 100, 'mario');
      }, 
      Update: function() {
            //... skipping lines ...
            //use this.player here
            var hitPlatform = this.game.physics.arcade.collide(this.player, ground);
       }
 };
