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"

Building System Collision Boxes Set Up

I'm trying to set up a building system similar to the one in Fortnite but I ran into a huge issue. I can't get the boxes to line up in certain situations and this causes the whole building system to be thrown off. Can someone please help me with a building system where all the walls would line up? Thank you.

you should be able to round the locations to the nearest value, so basically create a snapping system. to do this you could break the vector and use the floor or round nodes on each axis (i dont know of a way to round all axis at once as a vector). so say you wanted to snap to the nearest 100units or meter for each axis you would: take the axis value divide by 100, then round, then multiply by 100. so as an example lets say you were aimed at X213, the it would be 213/100=2.13, 2.13 rounded is 2, 2*100=200.

also i dont know if you know but theres a guy already making a tutorial on how to recreate the building system in fortnite. i havent watched his videos but ill link them anyways.
