如何修改C#代码实现Unity中Kinect控制物体连续旋转？

Hey there! Let's figure out why your object stops rotating once it hits the left/right extremes when using Kinect. Based on what you've shared, here are the most likely culprits and how to dig into them:

1. Hardcoded Rotation Clamps #

Sample code often adds rotation limits to keep demos focused, but this might be what's holding you back. Check your rotation logic for lines that restrict the object's angle range, like:

// Example: This clamp stops rotation at ±90 degrees on the Y-axis
float clampedYRotation = Mathf.Clamp(transform.eulerAngles.y, -90f, 90f);
transform.rotation = Quaternion.Euler(0, clampedYRotation, 0);

If you find this, either remove the Mathf.Clamp entirely or adjust the min/max values to fit your desired rotation range.

2. Kinect Hand Position Thresholds #

Your plugin's sample code might be cutting off rotation input when your hand moves outside a predefined area of the Kinect's field of view. To test this, add debug logs to track your hand's position when rotation stops:

// Add this in your Update() method to monitor right hand position
Vector3 rightHandPos = KinectManager.Instance.GetJointPosition(KinectInterop.JointType.HandRight);
Debug.Log($"Right Hand X: {rightHandPos.x}, Current Object Rotation Y: {transform.eulerAngles.y}");

If the log shows your hand's X value hits a fixed limit when rotation stops, you'll need to adjust the plugin's input range settings or modify the code that checks for valid hand positions.

3. Gesture Completion Logic #

Since you're using a GestureListener class, there might be code that marks a gesture as "finished" once your hand reaches a certain position. For example:

if (isGestureCompleted)
{
    // Stops rotation updates once the gesture is marked as done
    return;
}

If this is the case, you'll need to tweak the gesture completion criteria or switch to a continuous input mode (instead of gesture-based triggers) to keep rotation going as long as your hand is moving.

Next Steps #

To nail down the exact issue, sharing the full GestureListener code—especially the parts that handle Kinect input and apply rotation—would help a lot. In the meantime, start with the debug logs and clamp checks; those are usually the quickest fixes for this kind of problem.
