Following the next steps, you will have your first Scratch game:

• Make a road, where the Sprite is walking. Use the Estágio section and Paint.
• You can use any colour for that.
• Set the brush size to 100.

       

• Make the road something similar to the picture

     

• Make your Sprite smaller. It has to be two times smaller from the road width.
• Click on your Sprite and then use Traje button from the left corner.
• Use the arrow button to select the whole Sprite and use points to make it smaller.

   

• You can see the suggested size on the picture (with road and Sprite)

       

• Now we are going to program the Sprite.

 

• Program starts with the When <flag> clicked button from the Events section.
• Next step is to define the starting position for the Sprite. Place the sprite to desired location (totally on the road) and use the go to x … y… button from the Movimento
• Next add the set rotation style (left-right) button from the Movimento section to your program. This helps to hold the sprite for not rotating.
• Program should look something similar to the picture.

   

• Next step is to program your sprite to move with keyboard arrows.
• If you press Up arrow, Sprite will point up and moves 10 steps.
• If you press Down arrow, Sprite will point down and moves 10 steps.
• And the same with left and right arrow.
• Use the When (*direction* arrow) key pressed button from the Events Change the key accordingly to up arrow, left arrow, down arrow, and right arrow.

 

• Add the other buttons and change accordingly.

 

• Now you should move your sprite with keyboard arrow keys to up, down, left, and right

       

• Now we need to make the game harder.
• If the sprite goes outside of the road (touches white area) it will be transported back to the starting position.
• For that we need the if… then button from the Controlar
• Meaning: If the cat touches white then go back to starting position.
• For touching white we must use the touching color … ? button from the Sensing
• Change the color to white by clicking on the color, then click on color picker icon and then click on white or just put the values accordingly:Color 0, Saturation 0, Broghtness 100.

 

• Now add the go to x … y … script or glide 1 sec to x … y … script from Movimento section to your program.
• Change the x and y values accordingly.
• We need to check the white touching all the time. For that we need to add forever loop into our main program.
• Use the forever script from Controlar section to do it.
• Your main program should look similar to this.

     

• Try it out! Is the sprite gliding back to start when touching white?
• Cool! The game is almost ready.
• The game was called “Catch the bus”, so next step is to add the bus to your game. You can use the Choose a Sprite button for that and then choose the bus.
• Change the size of the bus as wide as the road (use Costumes for that) and place the bus to the end of the road.

     

• Now program the bus in a way that when it touches the cat (or your sprite), it says “Game over, you caught the bus. Good job!”
• Use the wait until script from Controls section and touching mouse-pointer? script from Sensing Change the last one for sensing your Sprite (Sprite1 for default)
• You can use the say Hello! script form the Looks
• Change the scripts accordingly
• Do not forget to use the green flag button and starting position

 

• Bus program should look something like this.
