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 module Lock axis does not work on ASP velocity

I need to create particles aligned to their velocity. However, they should always face up into the Z axis. It seems to work when the emmitter is set to ASP Square screen alignment. However, the ASP Velocity seems to ignor the Lock axis.

Not sure if it's a bug or simply not implemented. But it would be great to have :D

Hi Vita -

Sprites in Particle Systems only have one alignment axis to set, so if you set the alignment to velocity the sprites vector will be aligned in that direction. I would recommend using a plane and a Mesh Type Emitter which then you could set up your pivot to be 90 degrees from your velocity facing particle which would give you the Locked Z Axis with velocity alignment. From a performance cost, they would be virtually identical.

Thank You
