Java OpenVR binding

openvr's Issues

Which binding shall we start from?

Actually there are at least three different bindings available at the horizont:

• phr00t
• jherico
• stellaArtis

Jherico's one looks like a basic binding, without even a test to verify it works, like he himself said here

While the other two seems to be at the same level (0.9.19), phr00t looks like he had the chance to use it more extensively... here and here

Type errors (array of structures) in IVRCompositor_FnTable

In the method, vr.IVRCompositor_FnTable.WaitGetPoses_callback.apply(), the first parameter should be an array of structures. I created this with the statement Structure[] pRenderPoseArray = new TrackedDevicePose_t.ByReference().toArray(VR.k_unMaxTrackedDeviceCount); based on the Kotlin code in https://github.com/java-opengl-labs/jogl-hello-vr. However, this value can't be passed into the apply method in Java since the types don't match.

I've also tried

Object pRenderPoseArray = new TrackedDevicePose_t().toArray(VR.k_unMaxTrackedDeviceCount); _vrCompositor.WaitGetPoses.apply((TrackedDevicePose_t) pRenderPoseArray, VR.k_unMaxTrackedDeviceCount, null, 0);

and

Object pRenderPoseArray = new TrackedDevicePose_t.ByReference().toArray(VR.k_unMaxTrackedDeviceCount); _vrCompositor.WaitGetPoses.apply((TrackedDevicePose_t) pRenderPoseArray, VR.k_unMaxTrackedDeviceCount, null, 0);

but they both give runtime errors (type mismatch)

Any suggestions on how to get this working in Java?

Check bool variables

for example [VREvent_TouchPadMove_t] bFingerDown in C is boolean

bool bFingerDown;

in the phr00t code is

public byte bFingerDown;

check
