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

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

Sense and Sense Ability

Online session IITU100 13J

Page 4: Sense and sense ability - TU100 13J

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

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

Page 6: Sense and sense ability - TU100 13J

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.........

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….

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

Page 10: Sense and sense ability - TU100 13J

An exercise

• Create, name and paint your sprite

• Green tick when you’ve finished

Now we can look at the palettes

Page 12: Sense and sense ability - TU100 13J

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

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”

Page 14: Sense and sense ability - TU100 13J

An exercise

• Put it together a script to draw a line for 50 steps

Page 16: Sense and sense ability - TU100 13J

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

Page 17: Sense and sense ability - TU100 13J

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

Using blocks

• Duplicating a block

• Right click

• Deleting a block

• Right click

• Splitting a block

• Click and drag down

Page 20: Sense and sense ability - TU100 13J

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

Page 21: Sense and sense ability - TU100 13J

An exercise

• Draw a square with a side length of 75 steps and starting at 0,0

• Green tick when it’s done

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

Futures

• Heather Morris's R13 room

• 12th December at 19:00 and repeated on 14th December at 10:30

• Iteration and conditions
