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"

Custom slider with 2 handle

Hi, I'm trying to create custom slider based on existing slider class in c++, which I'm just trying to make the slider has 2 handle, so I mimicked everying in Slider.cpp, Slider.h, SSlider.cpp and SSlider.h. It already works with multiple object created on the blueprint, it also works with binding OnValueChanged on multiple objects created, also I created OnValue2Changed bindables, with one OnValue2Changed bind it works fine, but when create another OnValue2Changed binding in another object there's an error

LogBlueprint: Error: [Compiler main] Internal Compiler Error: Tried to create a property K2Node_ComponentBoundEvent_Value2 in scope ExecuteUbergraph_main, but another object (FloatProperty K2Node_ComponentBoundEvent_Value2) already already exists there.

In C++ code, because there's 2 handle so I create another binding for the second value

 .OnValue2Changed(BIND_UOBJECT_DELEGATE(FOnFloatValue2Changed, HandleOnValue2Changed))

Any suggestions appreciated. Thanks
