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"

Setting Collision on Particle Effects

For some background, I'm currently making a laser beam projecting from a hole in a wall, the laser beam distance is dynamic so if its placed between walls of differing distance it will still reach from wall to wall, meaning I can't just use a single collision box inside the blueprint. The aim of this beam is to kill any characters with a specific tag that pass through it so I want to be able to have overlap detect on the particle itself.

So my question is: how to do I create collision for the beam that will give overlap responses within the blueprint?
