我正在尝试做一个openvr java 绑定的kotlin 端口,并将其更新到 1.0.3
我开始写IVRSystem
结构/类
我手动编写了所有方法,以确保 Intellij 中的自动翻译器不会出现任何错误
我摆脱了来自不同数量字段的所有错误,getFieldOrder()
但现在我仍然收到错误:
Exception in thread "main" java.lang.IllegalStateException: Pointer native@0xffffffff already mapped to Proxy interface to native function@0xffffffff (IVRSystem$GetEyeToHeadTransform_callback).
Native code may be re-using a default function pointer, in which case you may need to use a common Callback class wherever the function pointer is reused.

根据此评论,似乎对特定回调(GetEyeToHeadTransform_callback
?)有多次调用,但事实并非如此,我检查并仔细检查了代码,该回调只有一个引用。
还可能是什么?
编辑:
首先,这发生在我read()
上课时IVRSysten
,但我无法避免......
其次,我看到这里所有以前的方法都得到了真实的地址,例如native@0x7fee4bebfd0
,只有GetEyeToHeadTransform
得到总是native@0xffffffff
......
编辑2:
调查原始代码
dprintf("GetRecommendedRenderTargetSize %p\n", &vr::IVRSystem::GetRecommendedRenderTargetSize);
dprintf("GetProjectionMatrix %p\n", &vr::IVRSystem::GetProjectionMatrix);
dprintf("GetProjectionRaw %p\n", &vr::IVRSystem::GetProjectionRaw);
dprintf("ComputeDistortion %p\n", &vr::IVRSystem::ComputeDistortion);
dprintf("GetEyeToHeadTransform %p\n", &vr::IVRSystem::GetEyeToHeadTransform);
dprintf("GetTimeSinceLastVsync %p\n", &vr::IVRSystem::GetTimeSinceLastVsync);
dprintf("GetD3D9AdapterIndex %p\n", &vr::IVRSystem::GetD3D9AdapterIndex);
dprintf("GetDXGIOutputInfo %p\n", &vr::IVRSystem::GetDXGIOutputInfo);
dprintf("IsDisplayOnDesktop %p\n", &vr::IVRSystem::IsDisplayOnDesktop);
dprintf("SetDisplayVisibility %p\n", &vr::IVRSystem::SetDisplayVisibility);
dprintf("GetDeviceToAbsoluteTrackingPose %p\n", &vr::IVRSystem::GetDeviceToAbsoluteTrackingPose);
dprintf("ResetSeatedZeroPose %p\n", &vr::IVRSystem::ResetSeatedZeroPose);
dprintf("GetSeatedZeroPoseToStandingAbsoluteTrackingPose %p\n", &vr::IVRSystem::GetSeatedZeroPoseToStandingAbsoluteTrackingPose);
打印出来
