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"

Set Target Arm Length, Third Person Character, Blueprint not Working

alt text

I put together this blueprint, the CameraDistance input is set to my mouse wheel, the idea was that when I scrolled the Spring Arm (named Camera Boom) would get longer or shorter. I have scroll down set to -1 and up to 1. However, when I compile and run it, nothing happens when I scroll. Any suggestions?

Hi! I wanted to know how to do the same thing that you wanted and when I found this post I tried your little blueprint. After tweaking with things for a while, I found a pretty simple solution!

In your project settings, delete the mouse wheel up and down in the axis mapping for the target arm length and put the mouse wheel axis with a scale of 1.0.

Now I simplified a but your blueprint because some of the stuff was unnecessary. Take a look:
