Javascript 用相器进行向内碰撞检测

我需要实现的是对玩家(主角)内部较小的hitbox与墙壁的碰撞检测，以便它给出玩家能够在墙壁旁边行走的图像.这应该非常简单，但碰撞检测确实有效.相关零件有墙层和hitbox sprote.这是我的代码:

preload(){
  //all the assets here
}
create() {
  console.log('create method executed');


  const characterPositionInWorldMap = 3700;
  this.hitbox = this.physics.add.sprite(characterPositionInWorldMap, 250, null); // we need collision for this
  this.protagonist = this.physics.add.sprite(characterPositionInWorldMap, 250, 'protagonist');
  
   // Initialize the hitbox sprite for collision detection
  
  this.hitbox.setSize(10, 10); // Set hitbox size (adjust as needed)

  
  this.protagonist.setDepth(3);
  this.hitbox.setDepth(3);
  const map = this.make.tilemap({ key: 'map' });
  this.animatedTiles.init(map);
  this.physics.world.createDebugGraphic();

// Add the tilesets...



// Create layers from tilemap data using different tilesets
const groundLayer = map.createLayer('Groundlayer', darkTileset, 0, 0);
const waterLayer = map.createLayer('waterlayer', darkTileset, 0, 0);
const grassLayer = map.createLayer('grass_and_tree_layer', darkTileset, 0, 0);
const stoneLayer = map.createLayer('stones_n_stuff', darkTileset, 0, 0);

// Create hut layer using the hut tileset
const hutLayer = map.createLayer('hutLayer', hutTileset, 0, 0);
const transportlayer = map.createLayer('transportlayer', hutTileset, 0, 0);
const walls = map.createLayer('walls', hutTileset, 0, 0);


  // Adjust the depth of layers as needed
  groundLayer.setDepth(1);
  waterLayer.setDepth(0);
  grassLayer.setDepth(1);
  stoneLayer.setDepth(2);
  hutLayer.setDepth(3);
  walls.setDepth(4);
  transportlayer.setDepth(10);

  // Enable collision detection between player and walls layer
  const collidableTileIndexes = [
    1279,1278,1244,1225,1257,1267,1302,1302,1320,1305,1277,1298,1307,1288,1319,1320,1321,1225,1223,1244
];

  collidableTileIndexes.forEach(index => {
    map.setCollision(index, true, walls);
});


  //animations....
 
  // Enable physics for the protagonist
  this.physics.world.setBounds(0, 0, map.widthInPixels, map.heightInPixels);

  // Listen for collision between hitbox and walls
this.physics.add.collider(this.hitbox, walls, () => {
// Disable movement controls for the protagonist
//this.protagonist.setVelocity(0); // Stop the protagonist's movement
console.log("hitbox hit")
});

// Listen for when hitbox stops colliding with walls
this.physics.add.collider(this.hitbox, walls, () => {
// Re-enable movement controls for the protagonist
// You may need to adjust this depending on how your movement controls are implemented
// For example, if you're using velocity-based movement, reset the velocity to allow movement
this.protagonist.setVelocity(0); // Reset velocity
});

this.groundLayer = groundLayer;
this.waterLayer = waterLayer;
this.grassLayer = grassLayer;
this.stoneLayer = stoneLayer;
this.hutLayer = hutLayer;
this.walls = walls;
this.transportlayer = transportlayer;


 // Set up camera to follow the player
 this.cameras.main.startFollow(this.protagonist);

}

update() {
  // Reset velocity
  this.protagonist.setVelocity(0);
  
  this.physics.collide(this.hitbox, this.walls, this.handleWallCollision, null, this);
    // Update the hitbox sprite position to match the player sprite
    this.hitbox.setPosition(this.protagonist.x, this.protagonist.y);
    ...
}
