Problem with MMF2 Pinball Movement.

[droberson]

I was working on a simulation to explore the building of a Bell Curve. I drop a ball onto a grid of pegs. The movement is the "pinball" movement to randomly allow a ball to bounce down thru the grid. A ball is released every second. I randomly vary how the ball (balls) drop so some go to the right and some to the left. In the end you would expect to see a bell shaped curve of the balls evenly distributed. However, it appears due the pinball movement that the balls are being "pushed" or "biased" to the right.

Even if I force the balls to always drop to the left side of the grid they get "basically" pushed to the right as the bounce (pinball) down thru the grid.

It appears to me to be a possible bug in the pinball movement code.

See the program attached.

Could someone at Clickteam verify this and will it be fixed.

Interesting, but argh this is going to be difficult to correct...

Does that mean there is no fix or perhaps a fix? If no fix, are there any suggested work arounds. I tried the bounce movement but that did not work. A custom movement perhaps? I have never worked with it however.

I also had a problem of balls not staying within the play area at the bottom. They would stop at the bottom as the code says. But then some would start moving down and off the screen. I tried saying STOP and STOP Animation but still had the problem.

What I was going to do was to let the ball images "stack" on top of each other to form a bar chart of sorts to show how the bell curve was being generated. Have not gotten to that yet.
