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"

Corrupted set variable nodes

There can be still multiple variables with the same name!

It shows only one variable of that name in the variables list but I have 2 different set variable nodes with the same variable name. When I set something in one of them it isn't there when I get it out of the output of the other node. It works fine when I use the input and output of only of the nodes. My guess is there is still something wrong with renaming variables which can cause existing nodes to get corrupted. Very annoying bug since you can easily spend hours wondering what is going wrong in a complex blueprint.

  1. Can you reproduce this issue in a new project?

  2. If so could you provide a detailed list of steps so I can reproduce this issue on our end?

  3. Could you provide screenshots related to your issue?

Turns out this is very easy to recreate: alt text

Just do it the same in a actor. So it has nothing to do with multiple variables with the same name. Probably with something how blueprints are now compiled.

I recommend for this set-up to use a get node instead of a set node to return the values.
