Here's a common problem with a tricky complication. A 20 x 20 square is struck by a 5 diameter circle travelling on a vector with components x and y. We know the x-y coordinates of the center of the ball, center of the square and rotation of the square. We also know the x and y components of the vector. The zero angle of rotation is straight up. The 0,0 point is top left. x increases to the right and y increases downwards.
What would be the resulting bounce vector when the ball hits the square? The trick is when you see that a horizontal hit at a 45 degree rotation will give a bounce upwards if the strike is above the center or downwards if it is below the center. I need a really tight algorithm to calculate the bounce vector no matter what the ball or square coordinates are, or the impact vector is. Good luck! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
