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"

I want to know how to show this Cylinder by camera rotation

when the player enter the collision the Cylinder visibility will be off but if the player rotated 180 degree in Z Axis than turned back the cylinder visibility will be on

I think you can set up an event that is called when player enter the collision area, which will keep updating while user remain inside that area, when player character rotate to a certain value in Z axis, you set up flag A, then if player character rotate to another value in Z axis, if flag A have been raised then you change that mesh visibility.
