Practical Game AI Programming

Generating grid nodes

Now we are going to implement what we have learned so far into a practical exercise. Let's start by creating or importing our scene into the game editor.

For this example, we are going to use buildings as non-walkable objects, but it can be anything that we choose, then we need to separate the objects that we just imported from the ground. To do this, we are going to assign them to a separate layer, and we are going to call it unwalkable.

Then we can start creating our first class of the game, and we are going to start from the node class:

public bool walkable; public Vector3 worldPosition; public Node(bool _walkable, ...
