Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Animate ScrollBox with Borders

The steps are as follow:

  1. Create a custom widget in Blueprint

  2. Add a canvas panel as the root node

  3. Add a scroll box in that root panel

  4. Give an image as its border (scroll box border), just thin lines

  5. Put a canvas panel in that scroll box

  6. Put lots of widgets inside the scroll box, in a position outside of the scroll box (so the scrolling borders will show)

  7. Create another separate custom widget in Blueprint

  8. Insert the 1st custom widget to the 2nd custom widget

  9. Create an animation for that 2nd widget

  10. In timeline window, animate the opacity of that 1st custom widget (from 1 to 0) to simulate fade out effect

  11. Play the game

Notice that the border of a scroll box does not follow the fading animation. It should follow right? Is this a bug?

Quick questions:

  1. Can you reproduce this issue in a clean project?

  2. If so, could you provide any small steps that may have been missed in the original post?
