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"

(4.7.2) My Game is Crashing when I try to play from Start to Finish

Hey Guys,

I'm having an issue with my game. It's a short boss battle with 4 phases. When I play through it somewhere in the second phase the game just crashes however if I use the shortcuts I built in It doesnt crash. I'm not really sure why it's doing it either.

I've included the Crash Report. Anyone have any suggestions?

Hi GD38Harley,

The document you posted is the crash callstack. If you could, go to windows explorer and to go your project saved files by going to \Unreal Projects\PROJECTNAME\saved\logs. Please upload the crash log and .dmp file from the most recent crash here.

Here are the requested Files. I'm under deadline and any suggestions on what might be causing this crash would be greatly appreciated.

Looking through your logs, I noticed a large amount of spam around a cast node to BP_Sandwicher, specifically in regards to setting an Actor RotationTarget. Can you show me a screenshot of your blueprint that contains this functionality? It looks like you may be casting to a null value or an actor has been recently moved/deleted so the actor doing the cast is looking for information that is no longer there and it hasn't been updated. This could definitely cause a crash if an object was deleted without being garbage collected or if you moved an object in the content browser and did not fix the redirectors to the object.

I believe this is the code you're asking for. What it's doing is constantly rotating my boss character so it's always facing towards the Player Character.

Try removing the cast here and just have it look at the player actor location without casting to see if it is the player. That information seems unnecessary with the setup you are currently using. Additionally, what is running your rotate timeline?

I set the timeline to auto play and loop so it runs on it's own. It works similarly to the Event tick but is less tasking. I've been debugging the last couple days and I think the crash has something to do with a destructible mesh called MESH_Pillar2_DM however I'm not completely certain.

If you remove that mesh does the crash still occur?

avatar image Sykrow. Apr 01 '15 at 10:53 PM

Yeah, I just removed them and it seemed to work but just crashed again. However this time it is from a different error.

Here are the Logs for the most recent Crash that I have gotten.

Try removing your contents folders except your map and run the project until the point that it usually crashes. If it does not crash add back in your blueprint folder, then try again. If it crashes, we can at least narrow it down to a blueprint by removing them then adding blueprints in one at a time until it crashes. Focus specifically on the blueprints in the area that the crash occurs to limit the scope of what you are working with.
