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"

Is there a way to toggle certain elements from a list?

Hello, noob here!

I am making a tile randomizer for the interior of a house. Currently I have it set to place an initial tile in a 4x4 grid, then randomly select a door in that room. It then checks the grid space that the door leads to to see if it is at the edge of the house and whether it is next to any other rooms with either a wall facing it or a door. It saves all of this information. I want to have a list of all possible tiles that can be placed in that space and do a systematic check where if for example, it is a bottom left space, the tiles where the bottom and left have a door are removed from the list, and so on for each wall and then randomly select a tile from the remainder to be placed in that grid space. Then of course, in order to continuously do this until the house is filled, the list would have to be repopulated.

Are there any flow controls or functions that can allow me to toggle whether elements from a list are unselectable after a check?

Thank you so much!
