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"

Issue detecting spawned physics actor/component with "Get overlapping actors/components"

There appears to be an issue with detecting actors and components that are simulating physics, using the "get overlapping -" nodes.

I'll try to break it down with the following picture:

alt text

The problem is the top one. The box trigger does not detect the sphere.

  1. If the sphere is moved, it will be detected. Such as being pulled by gravity, adjusting its during the spawn node or adding enough force to move it.

  2. If the sphere is placed in the level, it will be detected without the requirements above.

  3. If the sphere is not simulating physics, it will be detected.

Note that the sphere is not the root of the actor. If it is changed to be the root, then it will be detected. The problem is that I wish to have a base class for various physics actors, and setting the sphere to "default scene root" in the child class construction script does not work.

Provided project: https://www.dropbox.com/sh/qf93akcisfmgziz/AAA80WxBOCAbT3UiVEInROUda?dl=0 Open the test map and the relevant blueprints are TriggerActor & DetectActor

Well, I think I can work around it by not having a base class, but using an interface and actor component instead but I thought I'd report the bug anyway.

Hi ste1nar,

Sorry for the delay.

I was able to reproduce this using your test project; thanks for that BTW. I created JIRA UE-45023 and our developers will be investigating further. Please follow that link to monitor the status of the report.

Cheers,

TJ
