Question

我试图获得我的玩家角色所在的坐标，以便当他们从战斗中回来时＃39;他们会在他们开始之前站在他们所在的地方，但是我使用了crafty.js附带的fourway功能，所以我无法看到任何使用的变量，有没有办法我可以或者我必须制作自己的运动事件？

这是我的代码：

Crafty.scene('Yr10Tp1', function () {
Location = 3;

Crafty.e('2RoomCorridor');
//Draw Entites in the game world
//Drawing Other Entities
Crafty.e('Borders');
//
//Temporary dirty fix, need to find way to store player co-ordinates
//

if (monsterBeat == false)
{
Crafty.e('Enemy').at(22, 10);
Crafty.e('Player').at(PlayerX, PlayerY);
}
else
{
Crafty.e('Player').at(22,10);
}

Crafty.e('TeleporterYR10TP1_1').at(16,1);
});

    Crafty.c('Player', {
init: function(){
this.requires('Actor, Color, Fourway, Collision, spr_player, SpriteAnimation,    Keyboard')

.color('none')
.fourway(3)
.stopOnSolids()
.onHit('NPC1Event', this.Level2)
.onHit('Enemy', this.attackEnemy)
.onHit('TeleporterHubWorld', this.Level2)
.onHit('TeleporterSpawn', this.Level2)
.onHit('TeleporterYR10TP1', this.Level2)
.onHit('TeleporterYR10TP1_1', this.Level2)
.onHit('TeleporterYR10TP1_1.1', this.Level2)
.onHit('TeleporterYR10TP1_1.2', this.Level2)
.onHit('TeleporterYR10TP2', this.Level2)
.onHit('TeleporterYR10TP3', this.Level2)
.onHit('TeleporterYR11TP1', this.Level2)
.onHit('TeleporterYR11TP2', this.Level2)
.onHit('TeleporterYR11TP3', this.Level2)
.animate('PlayerUp', 0, 0, 3)
.animate('PlayerDown', 0, 1, 3)
.animate('PlayerRight', 0, 2, 3)
.animate('PlayerLeft', 0, 3, 3)
.bind('KeyDown', function () { if (this.isDown('SPACE')) Crafty.scene('World'); })
.bind('KeyDown', function () { if (this.isDown('F')) Crafty.scene('BattleScreen'); });

// this makes the Sprite animate on player input, need to analyse before I complete
var animation_speed = 10;
this.bind('NewDirection', function(data) {
  if (data.x > 0) {
    this.animate('PlayerRight', animation_speed, -1);
  } else if (data.x < 0) {
    this.animate('PlayerLeft', animation_speed, -1);
  } else if (data.y > 0) {
    this.animate('PlayerUp', animation_speed, -1);
  } else if (data.y < 0) {
    this.animate('PlayerDown', animation_speed, -1);
  } else {
    this.stop();
  }
});
},

stopOnSolids: function() {
 this.onHit('Solid', this.stopMovement);

 return this;
},

attackEnemy: function(data) {
Enemy = data[0].obj;
Enemy.collect();
},

Level2: function(data) {
Teleporter1 = data[0].obj;
Teleporter1.collect();
monsterBeat = false;
},

Crafty.c('BattlePlayer', {
init:function() {
var MenuPos = 1;
var HealthPas = 100 + ',' + 100;
//Displays options for the first time with attack selected

this.requires('Actor, Color, spr_BattlePlayer, SpriteAnimation, Keyboard')
.color('none')
.bind('KeyDown', function () { if (this.isDown('SPACE')) Crafty.scene('World'); })
