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"

Niagara and Actors

How can I get coordinates of any Actor on the scene and transfer them to the editor of Niagara? I tried to look for variables that would be of this type (Actor) in Niagara itself, but found nothing. Maybe there is way to write a location to Vector and then send this data to Niagara-editor? I want to do this, and on BP I found function "Set Niagara Variable (Vector3)" - it takes name of parameter (which you need to create in advance in emitter) and Vector 3, i.e. something that just needs. Attempt to assign coordinates of Actor failed, at least for me, since the variable in Niagara simply remains equal to zero under any conditions.

If someone has advanced in this matter, then direct me to the right path! Thanks.
