AI not initially moving in packaged game

Development Programming & Scripting AI

(Using 4.27)So I have an AI Monster that is supposed to wander around, and chase the player if they are seen. The AI uses a patrol path to navigate the map. It works fine in the UE4 Editor. But when I packaged the game and launch it, the creature won’t initially move. The only way to get it to move is to walk to it’s spawn area and have it see you. Then it will chase you. But I don’t understand why it won’t wander around from the start. When it works fine in the editor.

I have messed with Navigation Mesh in project settings. Checking on Forced Rebuild, and changing runtime Generation to Dynamic. But still no luck.
Any help would be much appreciated.

How large is the patrol path? If you are streaming levels and such it could be getting stuck trying to go to a place that hasn’t been loaded in yet?

I don’t think it’s that huge. I have one level at the moment. It’s basically a square building with 3 different floors.

I genuinely don’t know what the issue could be. Did you use any strange or unusual assets to make the monster that Unreal might not be creating when you package?

6

Are you using level streaming? There’s a particular way you have to set up nav meshes to work with level streaming

I think so? I’m not entirely sure though. How would I verify?
And how should I set up Nav Meshs?

8

When you open your level, do you use a node called “open streaming level?” Or do you just have this one map and it automatically opens on game launch?

I have this one map and it loads when I launch.

Gotchya. Then my point is moot.

You could try disabling automatic nav mesh generation in project settings, deleting your navigation mesh recast actor in your level and then rebuilding your navigation mesh maybe?
