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"

Navmesh bounds doesn't work in android


I have an issue with a navMeshBound Volume.

I have a NavMeshBound Volume in a landscape. When I launch my game in UE editor is all ok. Also I have a main menu and when I launch the game from this menu my IA works perfect in my NavMeshBound.

The problem appears when I try launch the game in my smartphone. If I launch the level that contents the NavMeshBound my AI works good. But If I launch the game from the main menu and I click on play button the AI doesn't do anything.

I tried move the NavMesh a bit for make a rebuild but didn't work.

I'm using android 5.1.1. and UE 4.14.3.

alt text Note: I started my project in UE 4.13 but I had to update to UE 4.14.3. I deleted the project in my PC and I downloaded it from my GitHub repository and open the project again with UE 4.14.3

Thanks and best regards!

Product Version: UE 4.14

Hey WhyPewPew,

I've tested this in a clean project, and I'm not experiencing the same results. Could you please reproduce the issue in a clean project and provide me with a detailed list of steps I can follow to see the issue on my end?

Hi Sean! Thanks for your answer.

Could it work that I create a clean project and copy all files from my current project into the clean project?

Nope, you'll need to recreate the setup from scratch. Just try the TopDown project, as it already contains a Nav Mesh and has movement that relies on it so if that works then it must be an error with the project you're currently working in.

Same issue. Launching from a main menu and the NavMesh doesn't works. If I launch the game from the default map the NavMesh works in my mobile.

If I do the same in the editor the NavMesh works from main menu and from default map

After further investigation, I do not believe this is a bug. When you launch from the editor, only the current map is cooked, which is why when you attempt to open the other map, all functionality may not be working. I'd recommend packaging the project and installing it on your device that way, as this should cook all of the maps.

Let me know if that helps.

Have a great day
