Scratch - Create a jumping game

• Launch Scratch or mBlock by double clicking on the icon 
• Change the background following the illustrations

We are going to add the obstacle for our player:

• Choose the pufferfish from the gallery. Click "choose a sprite " and choose the pufferfish from the list of elements                       
• If it's too big, you can reduce its size by decreasing the number in the field "size" from 100 to whatever you need.

• Bring the cat to the initial position. Click on the cat and drag it to the position where you want it at the beginning of the scene. Then insert a block "Go to x: .. y: .." from the movement category right below the beginning of the program
  
• Add movement to the cat, changing its costume every one second. Insert a loop ("Forever" block from the control category on the left). In the loop, insert a "Next costume" block and then a one second pause.
• Make it jump when clicking with the mouse: We add the event "when this sprite clicked", so this part is executed when we click on the cat. It will change the vertical position up and after 3 seconds it will go back to the initial position.

• Select the pufferfish
• Add the "Go to x...: y:" block with the position where you want it at the beginning of the scene (right end of the screen)
• Add a loop with the "forever" block
• Add a "Glide ... to x:... y:..."block. The first number of this block will indicate the speed of the pufferfish, the second and third will indicate the left limit of the scene
• Add an "If...then" block within the loop. The conditions should be: if the pufferfish reaches the left limit of the scene, it will restart from the right of the scene

The game ends when the cat touches the object. We are going to add this to the scene.

• Click on the cat to activate it
• Add the following condition: wait until the cat touches the pufferfish and then:
  • start sound
  • say "oh!"
