（不，我的意思不是显示一个精灵非常基本的，我根本想不出更好的标题，因为我不完全了解什么错误。）
简单地说，我有一个精灵，当被绘制到屏幕上，会显示不出来，但如果我在做临时精灵做一些测试int main()并将其绘制到屏幕上，他们表现出了完美的罚款。 所以，我知道我做错了我的类的设计或东西，因为他们是在精灵将不会显示。
（注：我所有的类都是的命名空间下rpg::我会剪下来，以节省空间，但我可能会使用它在我的代码不加思考-所以要去除可能发生的任何混淆）

我知道有一吨的代码在这里，但我相信，至少大部分是相关的。 我没有丝毫的想法，为什么在图形组件精灵不显示，但临时精灵工作完全正常，即使这两个精灵纹理指向相同的纹理。 我的猜测是，我做错了什么与类内的抽奖功能，但它们看起来没什么问题。 我认为这是我的另一件事是，对象的精灵不会再让纹理出于某种原因，但我做到设置其质地为rpg::PlayerTexture在其HandleEvents()函数，以便它设置纹理肯定的，但它还是不解决它。 我是在一个完全丧失这一点，它可能是简单的东西。
感谢您抽出宝贵时间，通过这一切阅读，如果你能，我很想解释，为什么这个问题是问题。 谢谢
