C++ OpenVR-IVRSystem::GetControllerState始终返回空结构

我一定是做错了什么,因为在下面的代码片段中,if语句只在前四次迭代中传递,应该是控制器、vive跟踪器、耳机和灯塔。这告诉我我可以访问这些状态,但不知何故我无法读取信息
for (int i = 0; i < 1000; i++) {
if (m_pHMD->GetControllerState(i, &state, sizeof(state))) {
dprintf("%d", i);
if (state.ulButtonPressed != 0 || state.unPacketNum != 0 || state.ulButtonTouched != 0) {
dprintf("Some action?");
}
}
我无法想象这是一个bug,所以我猜我的配置有问题,或者我做了错误的查询。
非常感谢您的帮助 显然我犯了两个错误。 错误1是我使用了错误的示例文件。我使用OpenVr示例文件夹中的hellovr_opengl,但hellovr_dx12是可行的解决方案。它也必须有不同的配置,因为我复制了一个在hellovr_opengl项目中工作的函数,但在那里,它不工作!然后我复制了添加到hellovr_dx12项目中的函数,并能够获得Vive控制器的控制器状态 然而,我想得到Vive Tracker的状态,但它不起作用。在谷歌搜索之后,我发现了一个,所以我把它恢复到beta hoftix,它为我解决了Vive Tracker的问题 你必须打电话; vr::VRInput->SetActionManifestPath
