Question

我正在Phaser建立一个平台游戏。我有一个可以向左或向右移动的玩家。因为设置了游戏界限，所以当击中左边和右边时它会停止。屏幕的右侧部分。

主要游戏设置：

var game = new Phaser.Game(360, 592, Phaser.AUTO);
this.game.world.setBounds(0, 0, 360, 700);

相机跟随播放器：

this.camera.follow(this.player);

我有一个播放器的spritesheet包含它移动的动画，但它只剩下移动动画＆amp;我正在使用

this.player.scale.setTo(-1, 1);

在右移动的情况下播放反向动画，它正常工作。但是由于这种情况，右边界已经以某种方式降低了，即玩家在应该停止的实际位置之前击中了15px。

这是截图：

^当右碰撞完美时，即在右键动画上添加比例

^当比例设置为-1

时

注意：当向右移动时与火碰撞的事件发生在与墙壁相同的距离之前。

更新调试播放器主体后的结果＆amp;向右移动时：

当向右移动时，绿色框（即正文）实际上位于玩家的右侧。向左移动它完全在玩家身上。（game.debug.body(this.player);）

粉色边框是精灵（game.debug.spriteBounds(this.player, 'pink', false);）

观察： 我认为精灵正在翻转它的中心，因为它的锚被设置为0.5但是调试器框正在精灵的右侧翻转。很奇怪

以下是游戏的完整代码：

  var GameState = {
  init: function() {
    this.scale.scaleMode = Phaser.ScaleManager.SHOW_ALL;
    this.scale.pageAlignHorizontally = true;
    this.scale.pageAlignVertically = true;

    this.game.physics.startSystem(Phaser.Physics.ARCADE);

    this.cursors = this.game.input.keyboard.createCursorKeys();
    this.PLAYER_SPEED = 200;
    this.JUMP_SPEED = 670;

    this.game.world.setBounds(0, 0, 360, 700);

    console.log(levelData);

    }, this);

    this.camera.follow(this.player);

    this.createOnScreenControls();
  },

  update: function() {
    this.game.physics.arcade.collide(this.player, this.ground);
    this.game.physics.arcade.collide(this.player, this.platforms);

    this.game.physics.arcade.overlap(this.player, this.fires, this.killPlayer);

    this.player.body.velocity.x = 0;
    if(this.cursors.left.isDown || this.player.properties.isMovingLeft) {
      this.player.body.velocity.x = -this.PLAYER_SPEED;
      this.player.scale.setTo(1,1);
      this.player.play('walking');
    }else if(this.cursors.right.isDown || this.player.properties.isMovingRight) {

      this.player.frame = 4;
    }
    if((this.cursors.up.isDown || this.player.properties.isJumping )&& this.player.body.touching.down) {
      this.player.body.velocity.y = -this.JUMP_SPEED;
    }
  },

  createOnScreenControls: function() {
    this.leftArrow = this.add.button(20, 535, 'arrowButton');
    this.rightArrow = this.add.button(110, 535, 'arrowButton');

    this.leftArrow.alpha = 0.5;

  killPlayer: function(player, fire) {
    game.state.start('GameState');
  },

  render: function() {
    game.debug.spriteInfo(this.player, 32, 32);
    game.debug.body(this.player);
    game.debug.spriteBounds(this.player, 'pink', false);
  }

};

var game = new Phaser.Game(360, 592, Phaser.AUTO);
game.state.add('GameState',GameState);
game.state.start('GameState');

任何人都可以帮我解决这个问题吗？

Answer 1

我理解你的问题，你的球员物理身体有些如何向右移动它不是中心位置。没有查看正确的代码，我无法给你解决方案。我假设有一条像body.setSize(width, height, offsetX, offsetY);这样的行，如果然后注释掉该行并查看它是否解决了问题。另一个解决方案设置播放器的锚点 - this.player.scale.setTo(-0.5, 0.5);如果解决了你的问题。简而言之，你的玩家物理身体移动到玩家的右侧，以便它发生这个有线问题。

Answer 2

解决方案（种类）所以我继续编辑sprite＆amp;做了一个反思＆amp;将它附加在右边..所以现在我有右边和右边的差异帧左边的差异，但我仍然无法确定为什么规模黑客没有工作的原因。

这是新的精灵：

谢谢大家的帮助。
