Hey everyone.
The game I am working on involves AI and a large world composed of randomly generated world tiles. Due to this, I need to create a dynamic Nav Mesh with navigation invokers. My problem is water plays a big part in this game, and I have rising and falling tides which need to work with the AI pathfinding.
My current solution has been to have a Box Collision encompassing the space of the water, rising and falling as needed. However I have found when these volumes are in the scene set to anything other than NoCollision they seem to utterly break the Navigation Invokers ability to create a Nav Mesh surrounding itself. It seems to even not be really related to whether or not it is even in the same area as the Box Volumes.
I have made an image that will hopefully illustrate the problem…
I found [this thread][2], which seemed to experience similar problems involving physics volumes and nav invokers. Similar to them also, my AI characters remain static, but as I get closer to them the Navigation Invokers suddenly begin to work correctly.
I am also open to other ways in which to do water if anyone knows an alternative. As these pawns simply float on the surface and cannot dive it is effectively just a walking plane moving up and down. If anyone has any idea how to get that to work with a Nav Mesh, I would be grateful.
It should also be worth noting that the water is a giant plane interesecting these landscape meshes. I am unsure if the intersection between the two of them is the problem?
