6. Now, when you run the scene, assuming it is lit up and has the camera point-
ing where you want it to, you'll see
NPC
on
Terrain
.
7. Click somewhere on the
Terrain
object, and watch the
NPC
object move to
that point.
8. Although we might say that the pathfinding in this is clearly working, we
should also add an obstacle to the scene: something that shouldn't be
stepped on. To do this, add another cube somewhere. Go to the
Inspector
panel for the obstacle and tag it with
Obstacle
by selecting that tag from the
drop-down, or if it is not an option select
Add Tag...
and add
Obstacle
to
the tag list.
9. Next, in the
Terrain
game object, in the
Grid
component, expand
Disal-
lowed Tags
, increase the size to 1 and enter
Obstacle
for the new element.
10. Next, click on the
Bake
button at the top of the
Grid
component. Now you
will see that the grid markers skipped the cube as an option. If you want to
test more, click somewhere else on the
Terrain
object and watch the
NPC
object move to the clicked point avoiding the obstacle.
