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"

Possible to access mesh face positions?

I'm trying to positions objects about the face of a mesh at runtime, but I can't find any ways to access faces. I know how to get vertices but can't seem to do faces. I was thinking that the face index from a raycast might do something, but I'm not sure.

I don't think face position is even a thing. Faces are defined by their vertices, so you can only get the position of the vertices that conform it and the normal of said face. To get the "face position" you would need to calculate the "center" of the face which can be troublesome depending on the geometry, also, remember that faces are deformed when being animated so you would need to be constantly calculating a value that is ultimately unnecessary. Vertex is love, vertex is life.

If you are doing a raycast then you can get the point of impact, which I think should be enough for you to positionate your objects.
