Just a math animation - no controls! This uses no costumes and to <touching?> sensing. Everything is math and pen.
The ball will bounce off the circles with mathematically correct precision. I mathed the formulas myself. HOW IT CALCULATES The ball has the center Hb, Kb, and the radius of 16. Each circle has the center Ha, Ka, with radius of Ra. Therefore, the angle from the ball to the circle θb is atan(Ka-Kb / Ha-Hb). The ball must bounce over the line P perpandicular to the line connecting the two circles. The ball approaches at angle θv. I can explain further, but I would need paper to explain the geometry. Finally, you get the formula (new direction) = -θv - 2θb When the ball bounces off the X edge, it calculates (new direction) = (old direction) * -1 And off the Y edge (new direction) = 180 - (old direction)
