Then, add two variables for the memory. The first is a Boolean called
donePatrolling
, which will initially be
false
but will become
true
when the
5-second timer runs out, signaling the ship to return to the base. The second is
a GameObject variable that will store the navigation waypoint for the game base.
Create
gameBase
and set it to the game base GameObject.
Now that we have a memory set up, we can start modifying our behavior tree. We
already have part of the behavior tree set up that patrols the waypoint route. So, as
a next step, we will only let the ship continue to patrol if our
donePatrolling
Boolean
variableis
false

node.Therecall
constraint is the node that uses a logical expression and can evaluate success or
failure. Add the
donePatrolling == false
line to the constraint field in the
Con-
straint
node. The
Constraint
node will look like this:
