# Java Puzzle Ball Basic #10

edited Nov 10, 2017 5:01AM

I think there is a slight issue with the basic puzzles # 10.   I have managed to solve all with the exception of 10.  The ball misses Duke by the breadth of a hair.   It almost seems as though the right most blue bumper is slightly out of place or Duke's glove arm is a bit shorter.

......can't be me!  Any ideas, clues?

Congratulations!  Yeah, discovering the solution for this one takes a bit of thinking (or luck). The effects of the rotation wall plays a big role in the solution.

It was difficult but I managed to get through it. Sorry though, it was luck and I don't remember how I did it.

Well done.    But, I also find it difficult to remember how I solved the puzzle but it sure seems easier each time I try.

It just seems that I miss it by a few pixels.

Rotation wall is placed in the most logical position at 45 deg to horizontal plane of the ball.   Blower placed at 45 deg from top dead center.  Ball strikes rotation wall then veers off at 90 deg comes into contact bith blower stream and is pushed in the direction of Duke.

The ball passes within 1 pixel from Dukes glove.

I have tried different combinations but this is the closest.

This would be the rotation wall:

If a rotation wall is struck by the ball, it causes the bumper to rotate 90 degrees.  But the ball has to get a certain distance away from the bumper before the rotation can occur.  I had to program it this way, or else other attachments might slam into the ball while the rotation is occurring.

Oh!  I should also mention that screenshot doesn't show the solution

What you just described is more than likely what occurred but with the rotation wall and blower not being visible on the playing area.   Your screenshot is the scenario I was trying to describe.   Other scenarios cause the ball at times to ping pong between bumpers.
