I'm doing some animation and i'm trying to make the object I made move in a quadratic equation(parabola)

code:
x := 30
     d := 100
    y := round(-0.125 * (x - 300) * (x - 300) + 200)
    net (500, 0)
    for i : 1 .. 30
        x := x + 15
        y := y + 10
        basketball (x, round(y: real): int, 1)
        net (500, 0)
        delay (d)
        basketball (x, y, 0)
        net (500, 0)
    end for


It's not workign to well though...anyone see why?

where did you declare net? and where did you declare basketball?

code:
basketball (x, round(y: real): int, 1)


also, basketball cannot be called like that, it should be this instead:

code:
basketball (x, round(y), 1)
