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"

UE4.21.1 Collisions not working after Package and Build

For some reason after I package and build my game for Windows my "hit" events aren't firing. They work totally fine in the editor, but after the "Development" package they're not working at all. Anyone know why this could be?

After spawn Actor, custom object/trace channels and event hit work in editor but not packaged game.

the client connects to the dedicated server,isn't listen server

Product Version: UE 4.21

Same issue. Replicated using first person project. Balls work fine in editor, no collision in build. This is ridiculous.

I have same problem in 4.21 Everything works perfect on Editor but broken in packaged (shipment) build. I saw there are many posts about the same problem. Why nobody say anything from Unreal team?

Using Complex collision??????????

avatar image paradoc Mar 08 '19 at 08:54 PM

Same issue. Collision is fine (and has been through development). Most recent packaged shipping build, collision is corrupted and crashes the game. Some notes about project: migrated from 4.18, using engine source, 1 custom collision channel which was re-added after migration, previous shipping builds worked, in this case i'm using inclusive blueprint nativization. I don't think that has anything to do with the collision fatal errors, but just trying to isolate any differences between packaging attempts.

I solved my issue, maybe it can help others:

The "OnConstruction()" isn't called on an object that's already in the world in a packaged game :)
