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"

BlueprintImplementableEvent doesn't get called in PostEditChangeProperty


As the title says, whenever I call my event function inside of PostEditChangeProperty (or another function called by it) the event doesn't get triggered in blueprint.

I've debugged through my code and see that when changing a property the code executes the call, LOGs just fine but the blueprint event doesn't fire. Same behaviour happens when using BlueprintNativeEvent.

Firing the event from OnConstruction works just fine though.

 UFUNCTION(BlueprintImplementableEvent, Category = "Level Generator")
 void BuildLevel();

 void ALevelGenerator::PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent)
 void ALevelGenerator::OnConstruction(const FTransform &Transform)

Hey Cafeoh-

I tried created an Actor class with a BlueprintImplementableEvent called on PostEditChangeProperty. The function was called when a blueprint of my class was added to the viewport / compiled as expected. If possible, could you provide additional setup details or a small sample project that reproduces the issue you're seeing?
