我是这个领域的新手，在我的项目模块之一的简单平台游戏中遇到了太多麻烦 如果你们可以帮助或分享一些代码。这就是我到目前为止所做的。
我可以解析Tmx Map（使用平铺地图编辑器创建）并使用TmxParser库显示它，但我不知道如何处理Map Object，虽然我可以上网如何解析也使用了一个给出的例子自己的图书馆。但我不擅长编程，我想分享代码。
目标：制作一个简单的平台游戏，让玩家可以移动和跳跃 使用的工具：C ++，Tiled，tmxparser和SDL
请提前帮助谢谢！ 这是我的代码

答案 0 :(得分：0)
代码工作正常，应该能够显示example.tmx没有问题（确保你有一个＆＃34;示例＆＃34;目录中包含所需的文件）。至于有关Map对象的信息，我不会想到除了阅读平铺地图格式之外的其他方式（可在此处获取：http://doc.mapeditor.org/reference/tmx-map-format/）。如果您还有其他问题，也可以从Tiled的论坛（http://forum.mapeditor.org/）获得帮助。
至于你的目标＆＃34;制作一个简单的平台游戏，让玩家可以移动和跳跃＃34;这本身就是一个相当广泛的主题，我认为不能完全回答这里。
希望有所帮助。
