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 UDataTable factory memory Freeing crash

I created a factory which allows me to create a DataTable for my Weapons attributes. The factory creates the object ok, but the values are garbage, attempting to edit the rows, causes a free memory crash on the heap. Am i doing something wrong?

 UDataTable* UWeaponDataTableFactory::MakeNewDataTable(UObject* InParent, FName Name, EObjectFlags Flags)
 {
     UWeaponAttributeDataTable* WeapTable = NewObject<UWeaponAttributeDataTable>(InParent, Name, Flags);
     WeapTable->AddRow(FName("AttributeSet_Weapon.RateOfFire"), FAttributeRow(600.f, 400.f, 800.f));
     WeapTable->AddRow(FName("AttributeSet_Weapon.BaseDamage"), FAttributeRow(600.f, 400.f, 800.f));
     //Blah
     return WeapTable;
 }

I found the problem, i never set the default struct to be used, so it was allocating memory for FTableRowBase not FAttributeRow inside the AddRow function.

 U=WeaponAttributeDataTable::UWeaponAttributeDataTable()
 {
     RowStruct = FAttributeRow::StaticStruct();
 }

Seems to solve the issue.

Hopefully this is the valid soloution and i am not missing anything else, but the factory works at wanted now.
