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"

Make particle system generate overlap/hit events

I have a particle system using mesh data with the actor collision module. It will register hits on objects I have collision on because I can see it freezes as I've set it up in the particle system. However, none of the events (OnParticleCollide, OnComponentHit, OnBeginOverlap) on the system registers anything when it collides. I've also tried to make overlap events on the object it collides with but it's still not working. What have I missed?
