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"

Many-to-one and feedback loop connections allowed in UE4 blueprints

Under what circumstances is it allowed to connect:

  1. Multiple execution output ports (those with the blank triangle) in different branches to one single execution input, effectively merging the branches into one.

  2. Either an output port to an input in the same node, or to an input in a different node connected to the same branch but that is executed before. Both, for execution and data ports. Therefore effectively creating a feedback loop.

I know those rules are enforced by the editor, but I don't have one available at the moment.

OOMMBB,

for question 1, have never seen a limit, then again, I have only had one need for it to exceed 3 Output Exec pins going into the same input Exec pin.

If you mean an Out Exec pin, wiring back into the in exec pin on the same node, that will be stopped. it also won't really wouldn't accomplish much.

As to data passing between nodes. so long as it's an out data pin, going to a in data pin, have never seen that stopped unless it was different data types.
