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"

Detecting last input method. Using "Key Is ... Key" causes always dirty Blueprint.

Hi All,

I'm trying to write a function in the PlayerController that will determine if the last input entered was from a gamepad or was from a keyboard/mouse and pass the boolean result to the Pawn so that I can change some game elements based on what controls the player is using.

I tried to do this using the "Key is Gamepad Key" node in blueprint, but whenever I use that node (or any of the related nodes) the Blueprint always remains dirty after compiling. It compiles just fine without that, but that set of nodes in particular seems to be causing an issue.

If I just pass the Key struct to the Pawn and call a function in the pawn to do the "Key is Gamepad Key" check, it appears to work, bit it also has the weird side effect of the Pawn blueprint becoming dirty whenever I compile the PlayerController blueprint (but not the other way around).

I feel like I'm running into some bad programming practices here. Is there a better way that I should be doing this?

Product Version: UE 4.12

This is normal. When you change a blueprint that others depend on those other blueprints need to be updated also.

Your practices are valid, at least in this case ;)

I've just run into the same issue (UE4.14). Adding "Key is Gamepad Key" in any BP causes it to be unable to stay compiled. Returning to the graph after turning the BP editor off just makes it uncompiled again. Can you please explain why this issue is marked as solved?

We get this in 4.13.1 but not if I make a blank project and add to the thirdpersonplayercontroller.
