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"

Editor Launch Crash "Unknown structure."

Each time I try to launch I get an error around 93%, I don't know what would cause this, I deleted some presumably irrelevant blueprint, and the editor crashed. What's baffling me is that that blueprint is not mentioned in the error report. I've hardly touched anything as of late that would result in "PARENT_BP_Item_Coin.PARENT_BP_Item_Coin_C:ItemInfo" being mentioned. The blueprint doesn't even appear deleted, it's still in my content folder.

The error is as follows:

[ 0]LogProperty: Error: UStructProperty::Serialize Loading: Property 'StructProperty /Game/Blueprints/CoinType/PARENT_BP_Item_Coin.PARENT_BP_Item_Coin_C:UserConstructionScript.K2Node_MakeStruct_F_SpecificItem'.

I've also done this: https://answers.unrealengine.com/questions/294187/redirectors-bug.html - which has not worked for me. I'm very confused, as this error suggest that the editor is operational.

I've also seen it said to "fix up redirectors", I don't know how to do this outside of the editor.

I'm a little dismayed here, I'm close to getting this project on the market and I have this happen. Any feedback would be greatly appreciated.

I've managed to get a response from the editor by creating a new project and transferring the contents there, I can manage "PARENT_BP_Item_Coin" and its children, datatables, enums, structs... But, if I try to open any other blueprint, be that the game-mode, my character blueprint, any widget, it crashes.

I'm guessing there's an inconsistency concerning a variable related to a struct, but I can't get to it.

The Generate Visual Studio Project option is not available to me.

Problem solved by moving my character bp into another folder, this broke everything but allowed me access to fix whatever disconnects.
