食人魔-找不到请求的发射器类型。在ParticleSystemManager::_createEmitter中

Question

我试图从TinyOgre运行本教程，但仍然收到以下消息：

OGRE异常(2:InvalidParameterException)：无法找到请求的发射器类型。在C:/Intel/INDE/OgreSDK_1-9-0/Ogre/OgreMain/src/OgreParticleSystemManager.cpp的ParticleSystemManager::_createEmitter中(第270号行)

这是我的代码：

让我进一步澄清我的情况；我们在当前的项目中使用ogre进行可视化和数学，它提供了一些(我个人不做食人魔，而是其他项目的部分)。现在，我想编译“你好世界”的食人魔项目，并开始玩。我使用的是VisualStudio 2013和Ogre 1.9。我怀疑问题可能是我安装了食人魔，而不是根据wiki安装的，而是从另一台PC中复制出来的。但是我100%肯定这是工作安装，因为我有几个团队成员使用相同的安装(相同的路径、相同的环境变量等)，而对于我们的项目，它工作得很好，所以我不想把当前的安装搞得一团糟。例如，同样使用ogre的以下代码对我来说很好(但本例不使用resources.cfg)。谢谢

PS:首先，我想把这个寄给食人魔论坛，但似乎注册被破坏了(注册后没有邮件到达)，所以如果有人可以重新发布它，我会很高兴。

Answer 1

听起来好像您没有在应用程序中加载"Plugin_ParticleFX“。确保它列在您的"plugins.cfg“中。然后，这个插件将提供专用Ogre3D维基页面上列出的发射器类型。

论坛:注册工作。如果激活邮件没有到达您，请保持联系与我们一起，我们可以很容易地解决这个问题。
