GeoGebra 命令及参数

1. PointIn(e) → A
2. Vector((0, 0), A) → u
3. Polygon({(a, b), (a, (-b)), ((-a), (-b)), ((-a), b)}) → q1
4. Translate(P, Vector[(0.5 * u)]) → P'
5. Vector(P, P') → v
6. Circle(P, r) → c
7. RandomPointIn((-(a - 0.6)), a - 0.6, (-(b - 0.6)), b - 0.6 + (0 * n)) → food
8. Circle(food, 0.3) → foodC
9. Circle((0, 0), 1.5 + (0.08 * Min[25, n])) → f
10. RandomPointIn((-(a - 2)), a - 2, (-(b - 2)), b - 2 + (0 * bombn)) → bomb
11. Circle(bomb, bombr) → bombC
12. Circle((0, 0), 0.01 + (0.06 * Min[25, n])) → g
