L3 Navigation and Pathing
Learning Objectives
• All to learn the steps involved in programming
at least two different methods to make a Kodu
move, one manual and one automatic
• Most to apply a range of skills to modify and
create a simple Kodu game world which
interacts with objects
• Some to be able to explain the advantages of
both clones and creatables in terms of ease of
program maintenance

Navigation
• Navigation in a computer game
is an important aspect to
program
• What different methods of
navigation do you think we
might use in Kodu?
• HINT: Navigation methods can
be either Automatic or Manual

Navigation and Pathing
• Challenges: Manual navigation, Automatic
navigation and Pathing.
• Instructions: You have just
learnt a variety of ways to
code navigation into your
games. Now it’s time to
experiment yourself. Use
Worksheet 3 and follow the
instructions.

Recap so far
• Navigation is an important part of computer games
• Navigation can be coded to be either:
– Manual
– Automatic
• Pathing is a powerful concept in Kodu
• Combining concepts such as:
– “When See…”
– “Near by” and “Far Away”
– Pathing
• …can result in intelligent navigation

term cloning
mean?

What does the term cloning mean?
• “Cloning” means to make an exact copy of
something
• When we clone an object or character in a
computer game we copy all of its attributes
(colour, size) and all of its code

Cloning in computer games
• Why might the concept of cloning be useful in
computer games design?

Cloning vs Creatables
• You are about to see a demonstration of the
power of creatables in Kodu
• This is an advanced form of cloning which has
big advantages
• It is unlikely you will have come across this
concept before. Pay close attention as you
will be having a go soon!
