Я использую инфраструктуру Phaser для создания игры. У меня есть два файла: main.js
и Player.js
, предназначенные для хранения класса Player.
main.js:
import 'pixi'
import Phaser from 'phaser'
import Player from './controllers/Player.js'
var game = new Phaser.Game(1280, 703, Phaser.AUTO, '', {
preload: preload,
create: create,
update: update
});
var player;
function preload() {
this.stage.backgroundColor = '#eee',
this.scale.pageAlignHorizontally = true,
this.scale.pageAlignVertically = true,
this.scale.scaleMode = Phaser.ScaleManager.SHOW_ALL,
game.load.spritesheet( 'idle', '../../assets/sheet_hero_idle.png', 64, 64 ),
game.load.spritesheet( 'wall', '../../assets/roguelike-cave-pack/Spritesheet/roguelikeDungeon_transparent.png', 16, 16 )
}
function create() {
//Player Controller
//===========================
//Enable Physics on the world
game.physics.startSystem( Phaser.Physics.ARCADE );
game.physics.arcade.setBoundsToWorld();
//Enable input
game.inputEnabled = true;
//create player
player = new Player( game, game.world.centerX, game.world.centerY, 'idle' );
game.add.existing( player ); //Create on screen
game.physics.arcade.enable( player ); //Create physics body on this object
console.log("player is\t", player); //TEST
console.log("player body is\t", player.body); //TEST
console.log("player body is enabled\t", player.body.enable); //TEST
player.playAnim( 'idle', 10, true );
game.input.onDown.add( player.thisIsMyBody, this ); //When a click input occurs, call player.thisIsMyBody()
Player.js:
export default function Player( game, x, y, animKey ) {
Phaser.Sprite.call( this, game, x, y, animKey),
this.anchor.setTo( 0.5 ),
this.inputEnabled = true,
this.assets = {
animations: {}
},
this.animations.add( 'idle' ),
this.animations.play( 'idle', 10, true ),
this.alive = true
};
Player.prototype = Object.create( Phaser.Sprite.prototype );
Player.prototype.constructor = Player;
Player.prototype.thisIsMyBody = function(){ //TEST
console.log( "I am ", this );
console.log( "My body is ", this.body);
},
Player.prototype.playAnim = function( key, speed, isLoop ) {
this.animations.play( key, speed, isLoop );
},
Player.prototype.move = function() {
this.body.velocity.x = 30;
}
console.log("player is\t", player);
возвращает объект Player
console.log("player body is\t", player.body);
возвращает тело игрока
console.log("player body is enabled\t", player.body.enable);
возвращает true
Однако player.thisIsMyBody
возвращает объект game
и undefined
Есть ли что-то, что я пропускаю или неправильно использую this
?
