我正在使用 Phaser 制作垂直滚动平台游戏,但我不知道如何创建随机放置的平台以供跳跃。这是我到目前为止的代码(删除了不必要的东西):
Platformer.Game = function (game) {
this._platforms = null;
this._platform = null;
this._numberOfPlatforms = 15;
this._x = this.x;
this._y = this.y;
};
Platformer.Game.prototype = {
create: function (){
this.physics.startSystem(Phaser.Physics.ARCADE);
this.physics.arcade.gravity.y = 200;
this._platforms = this.add.group();
Platformer.platform.createPlatform(this);
Platformer.platform.createPlatform(this);
Platformer.platform.createPlatform(this);
Platformer.platform.createPlatform(this);
Platformer.platform.createPlatform(this);
Platformer.platform.createPlatform(this);
game.camera.follow(this._player);
},
managePause: function () {
this.game.paused = true;
var pausedText = this.add.text(100, 250, "Game paused. Click anywhere to continue.", this._fontStyle);
this.input.onDown.add(function(){
pausedText.destroy();
this.game.paused = false;
}, this);
},
update: function () {
}
};
Platformer.platform = {
createPlatform: function (game) {
var posX = Math.floor(Math.random() * Platformer.GAME_WIDTH * this._numberOfPlatforms * 70);
var posY = Math.floor(Math.random() * Platformer.GAME_HEIGHT * this._numberOfPlatforms * 50);
var platform = game.add.sprite(posX, posY, 'platform');
game._platforms.add(platform);
platform.events.onOutOfBounds.add(this.removePlatform, this);
},
removePlatform: function (game) {
this._platform.kill();
}
}
我可以让它随机放置它们,但平台游戏的想法应该是你实际上可以跳上它。有足够的距离但不是太多,所以我猜不是完全随机的。
希望你有一些想法!
