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"

Jerky widget animation


I'd like to report an issue that I realized on every engine version since I worked with. Here is the quick steps to reproduce the issue.

  • Create a new project

  • Create a new widget, add a "Text" in this widget, bigger is the font size more obvious is the result.

  • Create a new animation, add transform track, scale x, y, key at 0.0sec = 1.0 , and add the last key at 4.00sec = 1.05

  • Add it the way you want to be able to see this widget and the animation in "Play mode"

What is going to happen is that animation will be jerky, like is there is an anti-aliasing problem. This is the same with textures, image, material, boxes,... Nothing is wrong when the scale is growing fast, I mean you'll be barely able to see the problem, but if you try to put a small value on a long period, like in this example, this is obvious.
