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"

Spawn a sound on GPU particle collision

I simply want a sound to be spawned every time a GPU particle collides with a surface. I know that particle Event Generators can be set to 'Collision' and then linked to Blueprints. However, this option is only available for CPU or Mesh particle systems. GPU Particles do not have the event generator option.

Does anyone know of a workaround to this issue? Perhaps it is possible to:

a) Create a particle system composed of a primary GPU emitter and a secondary CPU emitter which are linked to each other.

b) Every time a GPU particle collides with a mesh, an empty CPU particle is generated.

c) The blank CPU emitter has an Event Generator and is used to fire the blueprint script which plays a sound file on "collision".

Any recommendations would be very useful!
