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"

Get vector away from surface hit?


So I'm trying to recreate the teleport function from the game Dishonored. When the player holds the button for his teleport, the player gets and indicator about wether or not he/she can jump up onto the surface.

The question I'm struggling with is to find a way for my linetrace to spawn the indicator with the correct rotation.

Basically, how do I always make my object face away from the surface no matter where on it I hit?

I made an illustration in paint to better show what I'm trying to achieve.


The challenge is to make it work on all objects no matter shape.

For LineTrace you can break the hit structure and get the "Impact Normal" value. This is the vector perpendicular to surface at the impact point of the LineTrace.
