Loops

🟨🐱 Technique Card: Using Loops in Scratch

Looking at how we can use loops in our Scratch projects!

🎯 What Are Loops?

Loops let you repeat blocks of code automatically, saving time and reducing errors. In Scratch, there are three main loop blocks in the Control category:

Loop Type	Description	Example Use
forever	Repeats the blocks inside endlessly	Make a sprite keep swimming
repeat (10)	Repeats the blocks a fixed number of times	Flap wings 10 times
repeat until	Repeats until a condition is met	Keep moving until mouse pointer is touched

🧪 Try It!

Make a sprite swim forever:

Make a sprite flap wings 6 times:

Make a sprite move until it touches the mouse pointer:

🎓 Top Tips

• Forever loops are great for movement, checking for input, or animations that never stop.
• Repeat loops are useful when you know how many times something should happen.
• Use repeat until with conditions like touching colour? or x position > 200.

💡 Handy Blocks to Combine

• wait (1) seconds – add a delay between repeats
• next costume – animate a sprite
• if on edge, bounce – keep sprites within the screen
• touching ___? – useful with repeat until

🛠️ Challenges

1. Make a sprite flap its wings 10 times using repeat
2. Make a sprite keep gliding across the stage forever using forever
3. Use repeat until to move a sprite until it reaches a certain x-position
