I got the sample level up and running - and I'll let my video do the rest of the talking! :)
This was another landmark week. I was finally able to get navigation meshes working with all the behaviors I’d implemented so far. To see how important this is, let’s consider an example: The follower (the smaller model) needs to get to the target position (the other character in this case). However, there is an obstacle in between. The steering algorithm doesn’t know anything about obstacles. So it will continually push the follower towards the actor, and into the obstacle. With a navmesh, we can tell the steering algorithms to follow a sequence of points in order to reach the target actor. Now, calculating this every frame is very expensive. So what do we do here? First, we raycast to the target position to see whether the follower can reach there uninterrupted. If it can, fantastic. We just ask the follower to seek to the target position. If there isn’t a direct path, we request the navmesh to provide us with a set of points that we store, and then seek to one by one. Wh...
