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"

UE 4.18 Collision Box Problem

I am creating a game that involves me using collision boxes within blueprints. I have just recently updated to 4.18 from 4.17 and in 4.17, the collision boxes were working fine and performing actions when the player walks into them. However, when updating to 4.18, the collision boxes perform the action without the player being detected. This problem will make completing a level in my game impossible. If anyone knows why this is occurring, please help. Thanks.

Hello SkillsX15,

I just updated a project that I had using a setup like you described from 4.17 to 4.18 and I was unable to reproduce the issue you described.

Please provide more information on how specifically your Blueprints are set up. If possible, please provide screenshots of your Blueprints, and video of the issue occurring.

Thanks, Tyler

This image is one of the many collision boxes that I have in my game. All of the blueprints in 4.18 are exactly the same in 4.17.

Here is a video showing you what happens in 4.17 and 4.18. https://www.youtube.com/watch?v=1fHjXT-BuA4&feature=youtu.be

Hello SkillsX15,

I still can't reproduce what you are describing. I have upgraded a project from 4.17 to 4.18, where my collision Blueprints looks very similar to yours, and it functions without issue. Would it be possible for you to provide me with a 4.18 project where the error happens? You can strip out any unnecessary portions out of the project before sending it, I only need enough to reproduce the issue.

Thanks, Tyler

The setup you got right now will trigger for everything. You can simply solve it if you take "Other Actor" and Cast it to your Character. Proceed only if it succeeds. In your case theres probably something overlapping already that triggers your event.

I'll try that and see if it works. Have there been changes to collisions in 4.18 because in 4.17 the collisions work perfectly?

Thank you very much. This worked and now everything is back to normal :)
