在Phaser.js中添加移动功能

var game = new Phaser.Game(width, height, Phaser.AUTO, 'game-container');

var sprite = game.add.sprite(x, y, 'sprite-image');

game.physics.startSystem(Phaser.Physics.ARCADE);
game.physics.arcade.enable(sprite);

sprite.body.velocity.x = speedX; // 在X轴上设置速度
sprite.body.velocity.y = speedY; // 在Y轴上设置速度

game.input.keyboard.onDownCallback = function(event) {
  if (event.keyCode === Phaser.Keyboard.LEFT) {
    sprite.body.velocity.x = -speedX; // 向左移动
  } else if (event.keyCode === Phaser.Keyboard.RIGHT) {
    sprite.body.velocity.x = speedX; // 向右移动
  } else if (event.keyCode === Phaser.Keyboard.UP) {
    sprite.body.velocity.y = -speedY; // 向上移动
  } else if (event.keyCode === Phaser.Keyboard.DOWN) {
    sprite.body.velocity.y = speedY; // 向下移动
  }
};

game.input.keyboard.onUpCallback = function(event) {
  if (event.keyCode === Phaser.Keyboard.LEFT || event.keyCode === Phaser.Keyboard.RIGHT) {
    sprite.body.velocity.x = 0; // 停止水平移动
  } else if (event.keyCode === Phaser.Keyboard.UP || event.keyCode === Phaser.Keyboard.DOWN) {
    sprite.body.velocity.y = 0; // 停止垂直移动
  }
};
