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"

Component not attaching.

I have a 3D SideScroller (no skeleton on the character or physics enabled). The character can attach an item but the other won't. the line of code runs to the end as if the AttahcToComponent node was executed properly, but the item doesn't get attached. "Blueprint Runtime Error: Accessed None trying to read property Legs from function: 'ExecuteUbergraph_Character_Name' from node: AttachToComponent in graph: EventGraph in object: Character_Name with description: Accessed None trying to read property Legs

Attach a screenshot of the blueprint, it will make it easier to help you.

At a glance, you're feeding the attach node an invalid object - either it does not exist or the reference is not set up properly.

here is the part of my blueprint that should attach the variable Legs. I have one excatly the same that properly attaches the variable called Ball. Both variables are a blueprint with a geo. i manage to attach the Ball with any of the lines of code. But my Varaible Legs wont be attach no matter how i setup the AttachToComponent alt text

The error message says that "Legs" variable of your BP is not set. You may use "IsValid" BP node to check component/actor reference value for correctness before use.
