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"

There is actually a really great example in the ContentExamples within the "Effects" level.

A spark which is activated between 1.2 and 4 seconds.

Here's a screenshot of the script it uses:

The activate node simply causes an existing particle system which only spawns it's particles once and not continuously to spawn them again.

If you want to check it out more in detail the blueprint is called "random_sparks" and the particle system used "P_spark_burst".
