2. You may remember these basic procedures walk, eat and breathe
Define breathe
Breathe in
Wait
Breathe out
wait
Define walk
Move right leg forward
Wait
Move left leg forward
wait
Main Algorithm
Loop always
breathe
if need to go somewhere
walk
if hungry AND food near
eat
Procedures
Define eat
Put food in hand
Lift hand to mouth
Put food into mouth
Loop until a paste
chew
swallow

3. Adaptable procedures are ones where we can add information to the procedure every time we run it.
Define walk (wait time)
Move right leg forward
Wait (wait time)
Move left leg forward
Walk (2 seconds)

4. Adaptable procedures are ones where we can add information to the procedure every time we run it.
Which will cause the procedure to walk faster walk (1 second) or walk (2 seconds) ?
Define walk (wait time)
Move right leg forward
Wait (wait time)
Move left leg forward
Walk (2 seconds)
Walk (1 second)

5. Adaptable procedures are ones where we can add information to the procedure every time we run it.
Which will cause the procedure to walk faster walk (1 second) or walk (2 seconds) ?
Define walk (wait time)
Move right leg forward
Wait (wait time)
Move left leg forward
Walk (2 seconds)
Walk (1 second)

6. We call the changeable part of a procedure a parameter
Walk (2 seconds)
Define walk (wait time)
Move right leg forward
Wait (wait time)
Move left leg forward

7. Here is another everyday example
Define breathe (wait time)
Breathe in
Wait (wait time)
Breathe out
Loop always
breathe (0.5 seconds)

8. Adaptable procedures can be used alongside basic ones
Define walk (wait time)
Move right leg forward
Wait (wait time)
Move left leg forward
Define breathe (wait time)
Breathe in
Wait (wait time)
Breathe out
Main Algorithm
Loop always
breathe (1 second)
if need to go somewhere
walk (1.5 seconds)
if hungry AND food near
eat
Define eat
Put food in hand
Lift hand to mouth
Put food into mouth
Loop until a paste
chew
swallow

9. Here is another everyday example
Define tongue_out (wait time)
Poke tongue out
Wait (wait time)
Hide tongue
tongue_out ( )
On your whiteboard change the parameter and see if your partner can act it out

10. Here is another everyday example
tongue_out ( )
Define tongue_out (wait time)
Poke tongue out
Wait (wait time)
Hide tongue
Can you use this adaptable procedure within a count controlled loop?
Write one for your partner to act out
