It works fine.

I can see on the video that you have problems with custom marker system for NGUI, right?
We fixed it. Now it will work correctly.
Please update Online Maps.

private void OnCompassChanged(float compass)
    {
        Debug.Log("compass : " + compass);
        int angle = (int)(compass * 360);
        this.MainUI.t_Compass.text = angle.ToString();
        this.Map.transform.rotation = Quaternion.Euler(0, 0, angle);
    }

The map will rotate well.

but When dragging a rotated map, marker is problem.

What is «angle» in your script?
The parameter is called «f».

The code that I tested, and that works for NGUI:

using UnityEngine;

public class RotateNGUITextureByCompass : MonoBehaviour
{
    private void Start()
    {
        OnlineMapsLocationService.instance.OnCompassChanged += OnCompassChanged;
    }

    private void OnCompassChanged(float f)
    {
        transform.rotation = Quaternion.Euler(0, 0, f * 360);
    }
}

I was late for an answer.

How use?

my version v2.4.0.53.

I've written to the code above

private void OnCompassChanged(float f)
{
        this.transform.rotation = Quaternion.Euler(0,0,angle); //(UITexture GameObject)
}

There are still problems (Marker Position problems) when Drag.

Update is now available.

I look forward to solutions.

This example is created for Tileset.
NGUI control does not support rotation of map.
If you want to rotate the camera / map, use Tileset control.

At the moment I have no idea how to convert the screen coordinate to relative point of rotated widget.
I'll try to ask NGUI creators. If they give me some advice, we will add this feature.

using UnityEngine;

namespace InfinityCode.OnlineMapsExamples
{
    [AddComponentMenu("Infinity Code/Online Maps/Examples (API Usage)/RoteteCameraByGPSExample")]
    public class RoteteCameraByGPSExample : MonoBehaviour
    {
        private void Start()
        {
            OnlineMapsLocationService.instance.OnCompassChanged += OnCompassChanged;
        }

        private void OnCompassChanged(float f)
        {
            OnlineMapsTileSetControl.instance.cameraRotation.y = f * 360;
        }
    }
}

NGUI Only Texture. The above source does not operate.

        private void OnCompassChanged(float f)
        {
            this.transform.rotation = Quaternion.Euler(0,0,angle); //(UITexture GameObject)
        }

The above source, rotate well. But there is a problem with touch and drag the marker.

Please NGUI Rotate the camera on a compass.

I'm sorry that I can not speak English.

Thank you.
