Hello, I am trying to create a simple movement script for bots. I created NavMesh, baked all static objects and added the agent.
Automatically I added some points which are the desirable locations for the bot to reach. Some of them lie outside the NavMesh. Is it possible to check: whether a target point is reachable or not? (lies in the NavMesh or outside)
Thank you very much!
The NavMesh.CalculatePath should be able to find which nodes are reachable inside the area mask.
http://docs.unity3d.com/ScriptReference/NavMesh.CalculatePath.html
Thank you for your help! The problem was in coordiates. I had different coordinates (local) for cubes and global for agent.
Here’s the working script to go from one point to another.
