🎯 What you'll learn: How to simulate gravity in Scratch using a variable, making a character feel realistic as it falls and jumps. This is the most important technique in platform games like Mario!
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1Gravity means constantly:
2Jumping changes:
3Landing is detected with:
4If falling and touching platform, set:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5Gravity: change y by each frame.
6Jump uses the key usually.
7Write simple gravity for the player.
8Jump when space is pressed (only on ground).
9Why use a y-speed variable instead of fixed jumps?
🚀 Section C · Challenge ● CHALLENGE 5
10What happens when the player falls off the platforms?

1-A 2-A 3-A 4-A | 5 a negative number 6 space/up 7 = forever [ change y-speed by -1; change y by y-speed; if touching ground: set y-speed 0 ] 8 = if touching ground and space pressed: set y-speed to 12 9 = It makes natural accelerating/decelerating motion | 10 = Reset to the start position (lose a life)
