to various AI classes, such as the AI's mind and senses. Here, we access
Work-
ingMemory
and can get the different memory items as well as set values for them.
That is all the action needs to do so that
ActionResult
can leave returning suc-
cess.
If we run the project now, we should see the ship patrol for 5 seconds, but instead of
moving back to the game base, the ship just stops. The last thing we need to add is
a
move
node to the home base. Set the move target to
"gameBase"
(RAIN requires
the quotes), and as we want the ship to return home faster than it patrols, change
the speed to
10
. And since we want the ship to stop as soon as it is near the base,
change the
Repeat
dropdown to
Until Success
and set a
Close Enough
distance
to
0.1
. This will make the ship go to the
gameBase
target and stop. The screen
should look as shown:
If we run the demo now, the ship will patrol for 5 seconds and then just stop again.
The issue here is the
Sequencer
node: it goes through its children returning on the
first fail. After the
stopPatrolling
node is activated, the
constraint
nodes will return
failure, so when the sequencer calls, it stops after the first constraint. To remedy this,
right-click on the
sequencer
node and change its type to
Selector
and rename it to
selector
.
