javascript - Typescript - 移相器碰撞重叠功能不起作用

Question

所以我只是想在下落的物体和玩家 Sprite 之间进行简单的碰撞。没什么复杂的。

我正在尝试使用 game.physicals.arcade.overlap() 函数。

这是我的代码:

Player 类 ->

export class Player{
    game: Phaser.Game;
    player: Phaser.Sprite;

    constructor(game:Phaser.Game){
        this.game = game;
        this.player = this.game.add.sprite(400, 520, "Player");
        this.game.physics.arcade.enable(this.player);
    }

    create(){
    }

    update(){

        if (this.game.input.keyboard.isDown(Phaser.Keyboard.LEFT))
        {
            if(this.player.x >= -10){
                this.player.x -= 7;
            }
        }
        else if (this.game.input.keyboard.isDown(Phaser.Keyboard.RIGHT))
        {
            if(this.player.x <= 830){
                this.player.x += 7;
            }
        }
    }
}

坠落物体类 ->

    export class Rock {

    game:Phaser.Game;
    rocks: Phaser.Group;

    constructor(game:Phaser.Game){
        this.game = game;
    }

    create(){

        this.rocks = this.game.add.physicsGroup(Phaser.Physics.ARCADE);
        this.game.physics.arcade.enable(this.rocks);

        var x = 10;

        for(var i = 0; i < 9; i++){
            var rock = this.rocks.create(x, this.game.rnd.between(-30,-5), "Rock");
            rock.body.velocity.y = this.game.rnd.between(240,300);
            x += 105;
        }
    }

    update(player){
        this.rocks.forEach(this.checkPos, this);
    }

    checkPos(rock) {
        if (rock.y > 800)
        {
            rock.y = -100;
        }
    }
}

我使用重叠功能的主游戏文件 ->

 create(){

        this.difficulties = [];
        this.difficulties.push(new Difficulty(0, 5));
        this.difficulties.push(new Difficulty(1, 7));
        this.difficulties.push(new Difficulty(2, 9));
        this.currentDifficulty = this.difficulties[0];
        this.shouldChangeDifficulty = true;

        this.levelOne = new LevelOne(this.game);
        this.levelOne.create(this.currentDifficulty);
        this.currentLevel = this.levelOne;

        this.player = new Player(this.game);
        this.player.create();

        this.rocks = new Rock(this.game);
        this.rocks.create();
    }

    update(){
        this.player.update();
        this.rocks.update(this.player);

        this.game.physics.arcade.overlap(this.player, this.rocks, this.collisionHandler, null, this);
    }

    collisionHandler (player, rock) {
        console.log("Does it work ?!");
    }

我在 typescript 中的几个移相器函数上遇到了同样的问题。我能够使用内联 lambda 函数来工作。

this.game.physicals.arcade.overlap(this.player, this.rocks, (p, r) => {console.log("这有效吗？!"); }, null, this);
