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"

Calling c++ event from blueprint?

I am trying to call a c++ event from a blueprint, but it doesn't seem like it's getting called. I've defined my event like

 UFUNCTION(BlueprintNativeEvent, Category = "Animation")
 void EnterDashSlash();

 void UAnimationResponder::EnterDashSlash_Implementation()
 {
     GEngine->AddOnScreenDebugMessage(-1, 1.0f, FColor::Yellow, "EnterDashSlash_Implementation");
 }

Then in my animation blue print state graph, I click on a state and in the Entered State Event text box, I put EnterDashSlash. But when the animation plays, my text isn't logged. Is there something else I need to do to link this event to when an animation starts?

Try "BlueprintCallable" instead of BlueprintNativeEvent.

Although the function still run. I haven't used NativeEvent in a while. Don't you need to call the super function in BP?

BlueprintCallable causes a compile error because the declaration for EnterDashSlash_Implementation doesn't get created unless BlueprintNativeEvent is used.

You need to declare it the normal way. Without the _Implementation.

Just write down the function in c++ like you would normaly do + the UFUNCTION makro with "BlueprintCallable". You can then call it in the BP version (BP Child Class) of that Class.
