  • Trouble-shooting

5. Multi task

  • Open Sense in the background Ill leave time for experimenting and looking around as we work through this tutorial
  • Were going to take it slowly so dont worry
  • 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 dont understand you must stop me and ask!
  • Note that the UI has a number of right-click menus; if you cant see what you need try the right-click
  • You wont see a sprite just yet but dont worry.........

7. 8. 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 http://screenr.com/SR4s 9. An exercise

  • Create, name and paint your sprite
  • Green tick when youve finished

10. Now we can look at the palettes 11. 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

http://screenr.com/qm4s 12. 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

13. An exercise

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

14. http://screenr.com/fm4s 15. 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

16. An exercise

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

  • Use the About this project section to keep a note of what the project is about
  • Load projects using the Open option

20. Planning the programme

  • As the programs become more complex its 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 21. An exercise

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

22. An exercise http://screenr.com/jm4s 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 youve asked it to do
