Javascript Phaser 3 console. log()特定游戏角色的瓷砖属性

任何人都可以在一般层面上建议如何使用Phaser 3实现以下目标:

我需要能够以更新的方式控制敌人精灵的瓷砖或地形属性. idea 是更新角色动画，如果它在水上或陆地.我试过console.log(this.streetLayer.getTileAtWorldXY(this.enemy.x, this.enemy.y, true);，但world map在update()方法中未定义.或者有更简单的方法来实现这一点？我的游戏是一个自上而下的RPG.下面是完整的代码:

import "./style.css";
import Phaser from "phaser";

const sizes = {
  width: 960,
  height: 640,
};
let last_direction;
let enemy_terrain;


class GameScene extends Phaser.Scene {
  constructor() {
    super("scene-game");
  }

  preload() {
    // Load spritesheet for the protagonist
    this.load.spritesheet('protagonist', '/assets/mainCH.png', { frameWidth: 100, frameHeight: 100 });
    this.load.spritesheet('enemy', '/assets/waterspirit.png', { frameWidth: 150, frameHeight: 150 });
    
  
    // Load tileset and tilemap
    this.load.tilemapTiledJSON('map', '/assets/maps/testmap.json');

    this.load.image('tiles', 'assets/maps/terrain.png');
  }

  create() {
    console.log('create method executed');
    this.protagonist = this.physics.add.sprite(200, 550, 'protagonist');
    this.enemy = this.physics.add.sprite(200, 100, 'enemy');
    
    // Set up properties for the enemy
    this.enemy.speed = 100; // Adjust the speed as needed
    this.protagonist.setDepth(1);
    this.enemy.setDepth(1);
    const map = this.make.tilemap({ key: 'map' });



    // Add tilesets for each layer
    const Tileset = map.addTilesetImage('test-tiles', 'tiles');
  
    
    // Create layers from tilemap data
    const streetLayer = map.createLayer('street', Tileset, 0, 0); 
    const waterLayer = map.createLayer('water', Tileset, 0, 0); 

    console.log('Street Layer:', streetLayer); // Log the street layer object to check if it's properly created
    console.log('Water Layer:', waterLayer); // Log the street layer object to check if it's properly created
  
    // Adjust the depth of layers as needed
    streetLayer.setDepth(0);
    waterLayer.setDepth(0);
    map.setCollisionBetween(188, 188, true, waterLayer);
    map.setCollisionBetween(0, 0, true, streetLayer);

 /////////////////////////BUNCH OF ANIMATIONS START///////////////////////////////////
 /////////////////////////BUNCH OF ANIMATIONS END///////////////////////////////////
    this.cursors = this.input.keyboard.createCursorKeys();
    // Enable physics for the protagonist
    this.physics.world.setBounds(0, 0, map.widthInPixels, map.heightInPixels);
    this.physics.add.collider(this.protagonist, streetLayer);
    this.physics.add.collider(this.enemy, streetLayer);
 
  
    if(this.enemy.y >= 350){
        enemy_terrain = "street"
      this.enemy.play('enemy_move_street');
  
     } else {
        enemy_terrain = "water"
    
     }
 
 // Play the appropriate animation based on the collision result
 if (enemy_terrain == "street") {
     this.enemy.play('enemy_move_street');
     console.log("enemy on street");
  
 } else {
     this.enemy.play('enemy_move_water');
     console.log("enemy on water");
 }


 
  }

  update() {
    // Reset velocity
    this.protagonist.setVelocity(0);
   
    // Handle keyboard input
        XXXX
    this.physics.moveToObject(this.enemy, this.protagonist, this.enemy.speed);
 // Call updateInfo method
    this.updateInfo();
  }
  updateInfo() {
    let timedEvent = this.time.addEvent({ 
      delay: 1000, // once every second = 1000ms
      callback: () => console.log(this.waterLayer.getTileAtWorldXY(this.enemy.x, this.enemy.y, true)), 
      loop: true });
}
}

    default: "arcade",
    arcade: {
