As the title states, when my AI are following a target that is moving across water, the path will fail at certain points and after a while, teleport somewhere far away (usually underground somewhere).
The recast graph follows the ground on the bottom of the lake. The AI uses the RVO controller as well as the AI Path components. It can either be swimming on the surface of the water or somewhere between the surface and the ground and is completely determined by the target. For testing, I am having the AI follow the player. Swimming works great until the AI reaches a certain depth in the water.
Once this depth is reached, the path to the target will always fail with: Path Failed : Computation Time 0.00 ms Searched Nodes 0. After a few seconds, if you don’t push the AI back to shallow waters (or push them underwater), it will randomly teleport away.
To test that this does happen at a certain depth and it’s not just a random point on the graph, I swam across the bottom of the lake with the AI following me. Once I was at a certain distance from the shore, I swam straight up and sure enough, the AI lost it’s path on the way up.
Is the path failing because it is too far above the recast graph? If it is, is there a way to omit checking the height above the graph? It’s not really needed as the AI can both swim or levitate depending on situations.
