What does a command do?  Commands in programming allow an object whatever it is to do something. In the case of this object it will be your character moving.

Step 1 – Open your game

Step 2 – Go to the Scripts tab

Step 3 – Select Control

Step 4 – Drag “When [Space] key pressed” box into script area

Step 5 – Change Space to Up Arrow

Step 6 – Go To Motion

Step 7 – Add “Point in direction 90” to your script

Step 8 – Change the direction to “(0) Up”

Step 9 – Add “move 10 steps” to your script

Step 10 – Go back to control

Step 11 – Add “Stop Script” to the bottom of your script

Step 12 – Repeat this 3 more times  You should now create 3 new scripts for the following: -  Move Down  Move Left  Move Right  This is done in the same way you just need to change the options for the key pressed and the direction. As below: - ScriptKeyDirection Move DownDown Arrow(180) Down Move LeftLeft Arrow(-90) Left Move RightRight Arrow(90) Right

You have now made your character move, however if it goes to the edge of the screen it doesn’t stop this need to be fixed. If your scripts work move on to the next slide. If not you need to go back over the steps making sure you haven’t made a mistake.

Step 1 – Add “When (Flag) Clicked”

Step 2 – Add “Forever” to the script

Step 3 – Go to the Motion options

Step 4 – Add “if on edge, bounce” option to the script.

Step 5 – Active the flag for this to work properly

Complete  You have now created your own character and it should be able to move around the white screen and stop at the edges.  Well Done.
