Variables Intro 1 Solution

1. Count (and show) how many times you click on the button sprite. Assume we have already made a “clicks” variable.

   
       When this sprite clicked
       change [clicks v] by (1)
       
   

2. Reset the count of clicks to zero when you hit “r”.

   
       when [r v] key pressed
       set [clicks v] to (0)
       
   

3. There is a “Mario” sprite and a “Coin” sprite.

   • Show on the screen how many coins Mario has touched.
   • When Mario touches a coin, it reappears in a random location.
   • Assume you have already made a “coins” variable.

   
       when green flag clicked
       forever
       if < touching [Mario v] > then
         change [coins v] by (1) 
         go to [random position v]
       
   

4. Phil eats hamburgers. After he eats 5 burgers, he pixelates to “125”. When he eats 10 hamburgers, he “wins”. Have just one burger that reappears in a random position on the screen when Phil touches it.

   • Phil:

   
       when green flag clicked
       forever
       if < (burgers) = (5) > then
         set [pixelate v] effect to (125)
         end
       if < (burgers) = (10) > then
         broadcast [game over v]
         end
       
   

   • Burger:

   
       when green flag clicked
       forever
       if < touching [Phil v] > then
         change [burgers v] by (1) 
         go to [random position v]
