Adding automated navigation
The first step is to modify the level to support automated navigation. In the original game, the players control all the moving objects (the tanks), so pathfinding is unnecessary. Now that we want to add AI, we need to have a world representation through which the AI can move. Luckily, this process is straightforward, thanks to NavMeshes.
Creating the NavMesh
To do this, perform the following steps:
- Open the Navigation window (Window | AI | Navigation) and look at the NavMesh generation parameters. In this case, NavMesh generation is relatively easy: we are only interested in moving around on the ground surface plane, so there are no jumps, no links, and no slopes we need to care of.
- The only adjustment to the default NavMesh parameters we need to make is for the baking agent size (that is, the measures of the virtual agent used by Unity to verify whether a location is large enough to allow the Agent to pass).
- The tanks used in the...
