Reference

Everything you can call in sprite code, grouped by what it does. Auto-generated from Leopard 1.2.1 — 125 free functions and 235 engine members.

🎮 Free functions

These are the functions you use every day when writing sprite code. Pick a category to see them all:

🎨 Color Build and work with colors for effects and the pen.

🔁 Control Loops, waits, clones, and stopping scripts.

⚡ Events React to clicks, key presses, broadcasts, and the green flag.

📐 Layers Control which sprites appear in front of or behind others.

👀 Looks Change costumes, size, visibility, and speech bubbles.

🏃 Motion Move, glide, bounce, and rotate sprites around the stage.

🔢 Operators Math, random numbers, and string operations.
