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"

Get Children Components does not display Physics Enabled Actors

I am attempting to create a system in which you can pick up items in your left and right hand. The following blueprint is made to attach Blueprints of a certain class to the hand socket.

It loops through components in the blueprint to disable physics and collision, and then attach the object to the socket.

When "Simulate Physics" is set to active on the specific component/mesh in the blueprint, and I attempt to pick it up, it does not get listed in 'Get Children Components' and nor does it attach to the socket.

I am unaware as to what is causing this, as further testing shows that if I have physics simulation disabled before I start the game, and then physics is enabled by the game after 'dropping' an item I have picked up, I can then pick it up again and drop it, repeatedly.

I've run into the same problem. Thanks @noms for pointing out that it is the physics enable that's doing it. I have a simpler example in the attached screenshot.

Calling Get Children Components on a scene component with one physics enabled child, and then checking length of returned array results in 0. When I disable physics on the child the array length is 1.
