1. Welcome
Before we start please check that your
audio is setup and working
Use Tools->Audio->Audio Setup Wizard
and following the instructions
If you haven’t used OU Live before take a
moment to investigate the user interface
We’re aiming to start at 19:00 from 18:45
until then is for sorting out the technologies

2. BEFORE WE START...........
• I’d like to record this session for those unable
to attend
• If you would rather the session was not
recorded, i.e. if you do not consent, please
click the red cross. Otherwise click the green
tick
• The session will only be recorded if
everyone agrees to it

3. Sense and Sense Ability
Online session II
TU100 13J

4. We’re going to cover.....
• Palettes and where to find the various blocks
• Saving and loading scripts
• Distinguishing between types of block
• Creating and running scripts
• Editing scripts
• Troubleshooting
• We’re not doing loops and variablesWe’re not doing loops and variables

5. Multi task
• Open Sense in the background – I’ll leave
time for experimenting and looking around as
we work through this tutorial
• We’re going to take it slowly so don’t worry
• By all means play but show consideration for
others
• Let me know that you are ready to continue
by showing a green tick

6. Naming of the parts
• The next slide shows the names for some of
the bits of the UI (user interface)
• If I use any term which you don’t understand
you must stop me and ask!
• Note that the UI has a number of right-click
menus; if you can’t see what you need try the
right-click
• You won’t see a sprite just yet but don’t
worry.........

8. Saving and loading
• As with most applications use the “Save” or
“Save as” options to save the project
• Use the “About this project” section to keep a
note of what the project is about
• Load projects using the “Open” option
• As we work through this session you might
want to save your scripts….

9. Creating a sprite
Give the sprite a name
At this stage you will draw your sprite
using “Paint”
Use “Show” (on the right-click menu) to
put your sprite on the stage

10. An exercise
• Create, name and paint your sprite
• Green tick when you’ve finished

11. Now we can look at the palettes

12. Making them do something
• Drag components from the palette to the
“scripts” tab
• Create a “Start” event
• Add actions
• Tell it to stop
• String them together and run the script

13. Tracking progress
• If you want to see where the cursor has been
use the pen
• Start the pen drawing by putting it down
• Stop it by lifting it and get rid of the lines by
using “clear”

14. An exercise
• Put it together a script to draw a line for 50
steps

16. Space and time
• Use the “go to” to set the sprite position –
handy to reset the script........
• Use the speed slider to control how quickly
the script runs
• Show and hide are applied to the sprite and
do just that

17. An exercise
• Make your line start at 0,0 and hide the sprite
when the line is complete
• Green tick when you’ve done that – shout if
you have problems

19. Using blocks
• Duplicating a block
• Right click
• Deleting a block
• Right click
• Splitting a block
• Click and drag down

20. Planning the programme
• As the programs become more complex it’s
important to plan them first
• Use “plain language”
Start
Draw Sprite – circle?
Place sprite in the right place
Move it X steps
Rotate Y degrees
Do something else
Stop

21. An exercise
• Draw a square with a side length of 75 steps
and starting at 0,0
• Green tick when it’s done

22. An exercise

23. Troubleshooting
• Stepping through the code – use “Single step”
• Take out sections and run without them to see
what breaks
• Walk through the code (bench test) looking at
what you’ve asked it to do

24. Futures
• Heather Morris's R13 room
• 12th
December at 19:00 and repeated on 14th
December at 10:30
• Iteration and conditions

25. Q&A
• Hope this has been of use
