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"

Can't Set UProperty in C++, Why?

I'm trying to change the properties of any object through the TFieldIterator ..

Running my code with Begin Play I can actually print on the screen the value of some property, then change it and print property value modified .. . nothing else happens to the object after the value has been changed ...

I'm trying to change the intensity of a lamp .. the code seems to work and when I get the properties of the lamp returns the value that has been modified over the lamp not changes in intensity ... why?

 void UIllusionToolkit::SetFloats(UObject* Object, FName PropertyName, float PropertyValue)
 {
     UProperty* Property = Object->GetClass()->FindPropertyByName(PropertyName);
 
     if (UNumericProperty *NumericProperty = Cast<UNumericProperty>(Property))
     {
         if (UFloatProperty *FloatProperty = Cast<UFloatProperty>(NumericProperty))
         {
             void* ValuePtr = FloatProperty->ContainerPtrToValuePtr<void>(Object);
             FloatProperty->SetFloatingPointPropertyValue(ValuePtr, PropertyValue);
         }
 
     }
 }
