如果你不想使用伟大的应用程序**“平铺”**，最简单的选择是将应该有部分碰撞的平铺设置为不碰撞，然后迭代Map平铺，并将不可见的静态物理体放在上面。
这可能不是很优雅，但它工作得很好，如果你没有超过1000部分瓷砖在屏幕上，这应该不是一个性能问题。

以下是演示：

document.body.style = 'margin:0;';

var config = {
    type: Phaser.AUTO,
    width: 536 /8,
    height: 42,
    zoom: 4.5,

        default: 'arcade',
        arcade: {            
            gravity:{ y: 0 },
            debug: false
        }
    },
    scene: {
        create,
        update
    },
    banner: false
}; 

function create () {

    let graphics  = this.make.graphics();
    graphics.fillStyle(0x00ff00);
    graphics.fillRect(8, 0, 8, 8);
    graphics.fillStyle(0xff0000);
    graphics.fillRect(16, 0, 8, 8);
    graphics.fillStyle(0xff0000);
    graphics.fillRect(24, 0, 8, 8);
    graphics.generateTexture('tiles', 8*4, 8);

    var level = [
      [1,1,1,1,1],
      [1,0,0,0,1],
      [1,0,3,0,1],
      [1,0,0,0,1],
      [1,1,1,1,1],
    ]

    // Map for the first level
    var map = this.make.tilemap({ data: level, tileWidth: 8, tileHeight: 8 });
    var tiles = map.addTilesetImage('tiles');
    var layer = map.createLayer(0, tiles, 0, 0);
    layer.setCollision(1);
    
    this.player = this.add.circle(16,16,4, 0xffffff)
      .setDepth(2);

        partialCollisions.push(partialCollition)
      }
    });
    
    this.physics.add.collider(partialCollisions, this.player);
    
    this.keys = this.input.keyboard.createCursorKeys();
}

  let speed = 20;
  
  this.player.body.setVelocity(0)
  if(this.keys.up.isDown){
    this.player.body.setVelocityY(-speed)
  }
