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"

4.18 - Leap Motion : Position to WorldPosition

Hi, I'm currently new to the leap motion and there are few things that I don't understand. I'm using getnamo plugin but I can't manage to get the world position of the floating hands. I can use some tricks like translation and so that does what I want but I don't feel like it's the right way to do.

For example to obtain such result alt text

I had to do nasty things in my blueprint. alt text

Do you have any idea on how to do it properly ?

In the current engine plugin the positions are reported relative to your hmd/controller origin.

With that in mind, there are couple of ways to do this:

  • Simply adding whatever you query e.g. palm postion to your hmd position should give you its world location

  • Parent something like a scene node to the skeletal mesh that is being tracked then query it's world location

  • There should be a debug hand actor that does something like this in the leap plugin content, see the assets found under Plugins/LeapMotion/Content/Blueprints/Utility for blueprints.

  • Request access to the preview plugin via forum pm, which has simpler API
