我正在尝试从 this tutorial 运行 TinyOgre但我仍然收到以下消息:
OGRE EXCEPTION(2:InvalidParameterException): Cannot find requested emitter type. in ParticleSystemManager::_createEmitter at C:/Intel/INDE/OgreSDK_1-9-0/Ogre/OgreMain/src/OgreParticleSystemManager.cpp (line 270)
这是我的代码:

让我进一步说明我的情况；我们在我们当前的项目中使用 ogre 来提供它提供的一些可视化和数学(我个人不做 ogre，但其他项目部分)。现在我想编译“hello world”食人魔项目并开始玩。我正在使用 VisualStudio 2013 和 Ogre 1.9。我怀疑问题可能是我没有根据 wiki 安装 ogre，而是从另一台 PC 复制的。但我 100% 确定这是有效的安装，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)并且对于我们的项目它工作正常，所以我不喜欢当前的困惑安装。例如following code这也使用 ogre 对我来说工作正常(但这个例子没有使用 resources.cfg)。谢谢
PS:首先我想将它发布到食人魔论坛，但似乎注册已损坏(注册后没有收到邮件)所以如果有人可以重新发布它我会很高兴。
最佳答案
听起来好像您没有在您的应用程序中加载“Plugin_ParticleFX”。确保它列在您的“plugins.cfg”中。然后，此插件将提供 dedicated Ogre3D wiki page 中列出的发射器类型.
论坛:注册有效。如果激活邮件不知何故没有到达您手中，请get in touch和我们一起，我们可以很容易地解决这个问题。
关于c++ - Ogre - 找不到请求的发射器类型。在 ParticleSystemManager::_createEmitter，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42736326/
