This is the documentation for Pano2VR 4. You can find the new documentation for Pano2VR 5 here.

However, this document is still valid for the current version of Object2VR!

Loading bars visually indicate how much of the project has loaded. There is a pre-installed loading bar skin default_loading.ggsk, which you can edit (Go to Elements > Add Default Loading Bar). However, in the case you'd like to know how it was created you can follow the tutorial:

Part 1 - Building the loading bar[edit]

  1. Open a new Skin Editor document or an existing project.
  2. Use the Rectangle Tool, Rectangle4.png, to draw a long, thin rectangle (this is the loading bar).
    Make any further size adjustments to the rectangle by dragging on its handles.
    ◊ TIP: Draw the rectangle to the desired full length of the loading bar.
  3. Select the rectangle in the Editor or in the Tree to open its settings in the Properties section.
  4. Animate the bar to grow from left to right:
    1. Open the Appearance panel.
    2. Change the Scaling's Center position to center-left.

      ◊ NOTE: If Scaling is left in the center, the bar will scale out to both the left and right.
      ◊ TIP: To have a partially transparent loading bar, change the Alpha value to something less than 1.000.
  5. Open the Rectangle panel and choose a background and border color (optional).
  6. Open the Actions panel and create an action to hide the loading bar when loading is done:
    1. For the Source, choose Loaded and Hide Element as the Action.
    2. In the Target field, leave the default value, $self.
  7. To have the loading bar move, or scale, in relation to how much of the movie has been loaded, open the Modifiers panel:
    1. Choose Scale X for the Target Value. This will make the rectangle expand (or move) along its X-axis.
    2. Choose Loading as the Source Value. This will cause the rectangle to animate in relation to loading time.
  8. To have the bar scale to its current length, keep the Factor at 1.000.
    • To have the rectangle scale to twice its original size, for example, change the Factor to 2.000.
    • If your loading object must be visible from the beginning, increase the Offset. For example, if you want a portion of the loading bar to be visible, choose an Offset of 1.
  9. Move on to Part 2 to add text.

Part 2 - Adding text[edit]

  1. Select the Text tool, Text4.png.
  2. Draw a text box in the Editor. Position it and size it accordingly.
  3. Add the text by doing one of the following:
    • Double-click on the Text element in the Editor to make it editable and start typing or paste the text.
    • Add the text in the Text panel of the Properties section.
    ◊ TIP: You can use basic HTML tags here.
    ◊ TIP: Use $p, to represent the percentage of how much the movie has loaded.
    ◊ TIP: Use the Live Preview to see how the text will look on output.
  4. On the Position panel, in the Properties section, give the text box an, ID. This is helpful if you have multiple text boxes and need to quickly distinguish between them.

  5. In the Text panel, you can change the text color and text alignment.

  6. In the Rectangle panel, disable the Background and change the Border to 0. (optional)

  7. In the Actions panel, add an action to hide the text after the movie is finished loading:
    1. Choose Loaded as the Source.
    2. Choose Hide Element as the Action.

  8. Select the Container tool,Container4.png, and in the canvas, draw around the elements (the loading bar and the loading text box). They will become children of the Container.
  9. Anchor the Container to an area of the window.
  10. Anchor the elements to the Container. The top left is a good start.
  11. Click Close and save your skin.
    ◊ TIP: Save it to the Skins directory to have it available in the menu in the Flash and HTML5 output settings.
  12. Add your skin to a Flash or HTML5 output.
