Step 1: Understand the Stage Size

📏 Scratch stage is:

• X-axis: from -240 (left) to 240 (right)

• Y-axis: from -180 (bottom) to 180 (top)

Explain:

“If your player keeps going past these edges, they’ll disappear! We’ll write code to stop them.”

🧩 Method 1: Prevent From Going Offscreen (Simple)

if <x position > 230> then
set x to 230
end
if <x position < -230> then
set x to -230
end

–> Add these checks inside the forever loop under the movement code.

Explanation for choosing position:

• x position > 230 → if a player is too far right

• set x to 230 → Move it back to the edge

Step 2: Use “if on edge, bounce” (Fun Visual Option)

This makes the sprite bounce back instead of going offstage—it works well for arcade-style games.
