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"

Can you make a day/night cycle based off real life?

Hey, is it possible to create a day/night cycle that is based off real life? So if it is night time in real life, it will be night time in-game etc.

Hi! It should be possible. Lets say you have already a day/night cycle setup like this tutorial which it makes it rotate slightly every tick depending on a variable called "SunSpeed". You would need to change the setup so a single variable sets the rotation of light/sun. Ideally you end up with a float variable that when its value is 0 = day and 1 = night.

After you achieve this you only need to get the current time and interpolate the values. (ex. 12:00 = 0 to make it day and 24:00 = 1 to make it night). Hope this helped you ^^
