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"

Have you checked this out? It uses render targets for the exact purpose you want.

If you already got a line trace to apply damage, you can also use the same line trace to create smoke particle and decal(?) onto the surface of the hit object, check out the hit result and hit location mate.

okay, one problem i have with that set up is when the emitter activates, it stays in the same spot as where it hit, it doesn't attach onto the component where it hit. i am firing it at a destructible mesh so it breaks down into 500 pieces or so, then the emitter stays in the air where it was hit, how do i make it follow the path of the object it hit?
