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"

How can I get a line trace to hit an invisible sphere collider?

Right now I'm using LineTraceByChannel to extend out from the center of the camera to a pre-determined distance. I'm using this as part of an interaction system. I've got it reporting static meshes, things like floors and platforms, but what I'd like is for it to recognize the invisible sphere colliders surrounding certain actors - things like weapons, or buttons - so that the player doesn't necessarily need to hover EXACTLY over the actor to see that it's interactive. I'd like to have some kind of sphere or box collider around them that the line trace will hit, but the collider itself doesn't affect the actual actor's position or movement.

edit your colliders collision presets to ignore all the object responses and set block visibility in the trace responses only.
