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"

UI animations cause nativized builds to crash.

If you cook a fully nativized build of your game and have any UI animations, it will cook with no errors or warnings but trying to play the game will crash with the following error.

alt text

Deleting the animation and cooking again works perfectly. Although I saw several other issues like this, none had this specific error message and most could not be easily reproduced in 4.17.2, so I also made a very tiny project that reproduces the crash.

Hello blobdole,

I ran a few tests with the project that was provided. I was able to reproduce the issue in 4.17. However, the issue appears to have been resolved in 4.18. I upgraded the project to the current preview (4.18 preview 4) and the issue no longer occurred. I hope that this information helps.

Make it a great day
