// === Looping horizontal movement with ease in/out ===
// Customize these values:
amplitude = 200; // movement distance (in pixels)
speed = 2; // how many cycles per second
// Calculate time
t = time * speed * Math.PI * 2;
// Calculate eased position using sine wave
xOffset = amplitude * Math.sin(t);
// Final position
value + [xOffset, 0];上下ループ
