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"

Widget points at mouse cursor

I am trying to create a radial menu system. Currently, I has some code which rotates a widget around the center of the screen to face the mouse.

This code seems to only work in some aspect ratios / resolutions as seen in the video linked below. Any ideas of how this could be fixed?

Not an answer, more of a careful suggestion:

It may not be the case here but stretching the viewport like this will give you inconsistent results in many areas - it's not always interpreted correctly and not a great debugging tool. For example, the PIE geometry of the widget (and GetViewportSize, too, afair) updates only when one releases the left mouse button after changing window size - if you're tracking something in screenspace, this will be quite inconsistent, producing incorrect offsets not unlike the ones observed above.


Have you tried actually setting the resolution (the way the end user / final product would do it) and then observing the behaviour?
