Hi,

does anyone know how to recreate the bouncy ball effect in this game (Tangerines):

The most I can do at the moment is Pong-like rebounds off the wall...

Kind regards,

I think something like
 1  2  3  4  5  6  7  8  9  10  11  12  13  14  15  16  17  18  19  20  21  22  23  24  25  26  27  28  29  30 `// Ball.javaclass Ball{    public static final double GRAVITY = 6.0;    public double x, y; // position vector    public double vx, vy; // velocity vector    public Ball(double x, double y, double vx, double vy)    {        this.x = x;        this.y = y;        this.vx = vx;        this.vy = vy;    }    public move(double seconds)    {        x += seconds*vx;        y += seconds*vy;        if (somehow_collide_with_something)        {            x = collision_point_x; // that would be the same as x for floors            y = collision_point_y; // that would be the floor's height for floors            vx = reflection_of_vx_on_surface; // that would be the same as vx for floors            vy = reflection_of_vy_on_surface; // that would be -vy on floors        }        vy += seconds*GRAVITY;    }}`

or something like that (i would begin with something like the above and move forward modifying that).
