在开发游戏方面,我是新手,尤其是使用新的语言和框架。我在让相机粘在播放器上时遇到了麻烦。不知道我应该把 this.camera.startFollow();
语句放在哪里,这样它才能工作。该游戏是小行星重制版,但地图大于800x600。游戏已经通过 socket.io 设置好了。代码如下:
var config = {
type: Phaser.AUTO,
parent: 'phaser-example',
width: 3200,
height: 2400,
physics: {
default: 'arcade',
arcade: {
debug: false,
gravity: {
x: 0,
y: 0
}
}
},
scene: {
preload: preload,
create: create,
update: update
}
};
const game = new Phaser.Game(config);
function preload() {
this.load.image('ship', 'assets/spaceShips_001.png');
this.load.image('otherPlayer', 'assets/enemyBlack5.png');
this.load.image('star', 'assets/star_gold.png');
this.load.image('backgroundStar1', 'assets/star2.png');
this.load.image('backgroundStar2', 'assets/star3.png');
this.load.image('space', 'assets/deep-space.jpg');
//this.load.image('background', 'assets/background.png');
}
function create() {
var self = this;
this.add.tileSprite(0, 0, 6400, 4800, 'space');
this.physics.world.setBounds(0, 0, 3200, 3200);
//this.cameras.main.setBounds(0, 0, 3200, 3200);
this.socket = io();
this.otherPlayers = this.physics.add.group();
this.socket.on('currentPlayers', function (players) {
Object.keys(players).forEach(function (id) {
if (players[id].playerId === self.socket.id) {
addPlayer(self, players[id]);
//this.camera.startFollow(self.ship); - does not work
} else {
addOtherPlayers(self, players[id]);
}
});
});
this.socket.on('newPlayer', function (playerInfo) {
addOtherPlayers(self, playerInfo);
});
this.socket.on('disconnect', function (playerId) {
self.otherPlayers.getChildren().forEach(function (otherPlayer) {
if (playerId === otherPlayer.playerId) {
otherPlayer.destroy();
}
});
});
this.socket.on('playerMoved', function (playerInfo) {
self.otherPlayers.getChildren().forEach(function (otherPlayer) {
if (playerInfo.playerId === otherPlayer.playerId) {
otherPlayer.setRotation(playerInfo.rotation);
otherPlayer.setPosition(playerInfo.x, playerInfo.y);
}
});
});
this.cursors = this.input.keyboard.createCursorKeys();
this.blueScoreText = this.add.text(16, 16, '', { fontSize: '32px', fill: '#0000FF' });
this.redScoreText = this.add.text(584, 16, '', { fontSize: '32px', fill: '#FF0000' });
this.socket.on('scoreUpdate', function (scores) {
self.blueScoreText.setText('Blue: ' + scores.blue);
self.redScoreText.setText('Red: ' + scores.red);
});
this.socket.on('starLocation', function (starLocation) {
if (self.star) self.star.destroy();
self.star = self.physics.add.image(starLocation.x, starLocation.y, 'star');
self.physics.add.overlap(self.ship, self.star, function () {
this.socket.emit('starCollected');
}, null, self);
});
}
function addPlayer(self, playerInfo) {
self.ship = self.physics.add.image(playerInfo.x, playerInfo.y, 'ship').setOrigin(0.5, 0.5).setDisplaySize(53, 40).setCollideWorldBounds(true);
if (playerInfo.team === 'blue') {
self.ship.setTint(0x0000ff);
} else {
self.ship.setTint(0xff0000);
}
self.ship.setDrag(100);
self.ship.setAngularDrag(100);
self.ship.setMaxVelocity(200);
}
function addOtherPlayers(self, playerInfo) {
const otherPlayer = self.add.sprite(playerInfo.x, playerInfo.y, 'otherPlayer').setOrigin(0.5, 0.5).setDisplaySize(53, 40);
if (playerInfo.team === 'blue') {
otherPlayer.setTint(0x0000ff);
} else {
otherPlayer.setTint(0xff0000);
}
otherPlayer.playerId = playerInfo.playerId;
self.otherPlayers.add(otherPlayer);
}
function update() {
if (this.ship) {
if (this.cursors.left.isDown) {
this.ship.setAngularVelocity(-150);
} else if (this.cursors.right.isDown) {
this.ship.setAngularVelocity(150);
} else {
this.ship.setAngularVelocity(0);
}
if (this.cursors.up.isDown) {
this.physics.velocityFromRotation(this.ship.rotation + 1.5, 100, this.ship.body.acceleration);
} else {
this.ship.setAcceleration(0);
}
this.physics.world.wrap(this.ship, 5);
// emit player movement
var x = this.ship.x;
var y = this.ship.y;
var r = this.ship.rotation;
if (this.ship.oldPosition && (x !== this.ship.oldPosition.x || y !== this.ship.oldPosition.y || r !== this.ship.oldPosition.rotation)) {
this.socket.emit('playerMovement', { x: this.ship.x, y: this.ship.y, rotation: this.ship.rotation });
}
// save old position data
this.ship.oldPosition = {
x: this.ship.x,
y: this.ship.y,
rotation: this.ship.rotation
};
}
}
答案 0 :(得分:0)
通过在create()函数中添加以下代码解决:
window.scene = this;
然后更改了我的注释行
//this.cameras.main.setBounds(0, 0, 3200, 3200);
到
scene.cameras.main.setBounds(0, 0, 3200, 3200);
最后添加
scene.cameras.main.startFollow(self.ship);
在我的 addPlayer() 函数中。
