We’re going to cover.....

• Palettes and where to find the various blocks

• Distinguishing between types of block

• Creating and running scripts

• Editing scripts

• Loading and saving scripts

• Trouble-shooting

Page 5: Sense and Sense Ability

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

• Let me know that you are ready to continue by showing a green tick

Page 6: Sense and Sense Ability

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.........

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 9: Sense and Sense Ability

An exercise

• Create, name and paint your sprite

• Green tick when you’ve finished

Page 10: Sense and Sense Ability

Now we can look at the palettes

Page 11: Sense and Sense Ability

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

Page 12: Sense and Sense Ability

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 13: Sense and Sense Ability

An exercise

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

Page 14: Sense and Sense Ability

Page 15: Sense and Sense Ability

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 16: Sense and Sense Ability

An exercise

• Make your line start at 0,0 and hide the sprite when the line is complete

Using blocks

• Duplicating a block

• Right click

• Deleting a block• Right click

• Splitting a block• Click and drag down

Page 19: Sense and Sense Ability

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

Page 20: Sense and Sense Ability

Planning the programme

• As the programs become more complex it’s important to plan them first

• Use “pseudocode”

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

An exercise

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

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

Q&A

• Hope this has been of use
