Control Bar is a control element on Gothru Overlay Editor that sets up on-screen buttons intended to aid visitors in accessing information and navigating the entire virtual tour. The control bar includes the next and previous buttons, share buttons, map, sound, rotate, Fullscreen, hotspots, photo, and VR link button.

Following are the steps to add a control bar on your overlay:

4. You can round the corners of the control bar outer border edge using Border radius. Increase the value in each field to make a rounded corner.  If you click on the up arrow in the border radius field, GoThru Overlay automatically adjusts all 4 corners at once. To adjust one specific corner, click on the respected field and enter the desired number. The following example shows you the amount of roundness at 15-pixel border radius.

  • Rotate autoplay: It enables a panorama automatically rotate once you click on the play button, the panorama will be panning around.
  • Pano Walk: If you switch on the Pano Walk, the panoramas in the tour will load automatically, one after another at the specified time interval.
