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"

Particle emitter hits non-existent object

alt text

My waterfall drops particle emitter hits something before it reaches the water surface. I've checked several times if there's some hidden object probably, or collision, but I couldn't find anything. I moved the emitter to a different place, and it works as it should - particles bounce off surfaces and don't get stuck in the air.

What could possibly cause this?

Ok, so. I've tried to delete walls, floor, ceiling, rocks... see if anything could be interfering. I tried to move the entire level into a different spot. And lots of other things.

But after couple restarts of the editor, it somehow fixed itself. I guess it was just a bug then?
