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"

you never set the class on the get all actors of class node

personally though thats not the way i would go about setting up this script. what i would do is to use a public variable as the reference since its much cheaper, more reliable, and leads to a more versatile situation than using the get actors of class setup. to do this you would in your case create a variable in the door bp and sets its type via the details panel to the type clickbutton actor reference (as in the actor bp that you created). then hit the little eye box thing next to the variable in the panel on the bottom left to make it public. then once you place the door in the level you can select it and in the details panel you will be able to set the value of the variable.

my personal preference is usually to have the setup the other way around and have the switch reference the door but thats just me. hope that all helped
