Step 1: Introduce Movement with Arrow Keys

🧍 Sprite: Player (e.g., Cat, Steve, or custom character)

Explain:

“We want the player to move when we press the arrow keys, just like in a real video game!”

🧩 Code for Left & Right Movement:

when green flag clicked
forever
if <key [right arrow] pressed> then
change x by (10)
end
if <key [left arrow] pressed> then
change x by (-10)
end
end

Code Explanation line-by-line:

• when green flag clicked → Start the game

• forever → keep checking the keyboard

• if key pressed → If you’re pressing that arrow key…

• change x by → move left or right (x-axis)

Step 2: Add Costume Animation While Moving

Explain:

“Just like in real games, we want our character to look like it’s walking while moving. We’ll use ‘next costume’ to do this!”

🎭 Costume Animation Code (Inside movement):

Add this inside each movement block:

next costume

🧩 Updated Code with Animation:

if <key [right arrow] pressed> then
change x by (10)
next costume
end
