With the recent discussion on Flipper accuracy yesterday, I created a flipper test table for VP

 

It has 2 tests currently.

1) Ball is released from top of guide lane.  Flipper is triggered automatically by triggers on the playfield in 5 different locations along the flipper

2) Ball is released at about the cradle location above the flipper

Report can be printed out for review and comparison

 

Desktop and Cab vpt attached

 

Here are results from my Pincab:

Each row represents a trigger location.  Number is how many times the ball entered that kicker location.  With FPS high, shots are accurate but there are some anomalies (vp921 test#1 row4).  With FPS low, shots are affected.  Run the table and the values will make more sense.  DX9 test does not display the textboxes, but the report can still be printed out.  Try first on a DX7 version of VP to see how it works

Give it a try and post your results.  You can move the trigger locations around if you want to see if all angles are achievable

 

Next step if it makes sense to pursue:

-Add some light animation to see what it takes to degrade performance

- Kick the ball out at angles towards the flipper and trigger the flipper to meet the ball

- Add statistics like angle info, mean and std deviation 

 

Any suggestions welcome.  Feel free to mod.  I quickly create the scripts, so lots of duplication and very little optimization but it works

When posting your results, copy it from the debug window and post it here.  Don't worry about formatting it nicely in notepad.  The debug output will show up formatted.

Well done.

[gtxjoe]

Ahh, yes.  I remember watching the cool Unit3d pinball flipper test video when it was first posted.  Looking at that post now, I see it was based on your FP table      

 

I am tempted to put the automatic flipper controls onto a real table and see how well it would do

Try my Daffy Duck table and press A. This will make the table play itself, it works so good I bet it can beat your high Score eventually. I use to do this to test tables, just let them run.

[toxie]

Great, that table should help improving this strange issue!

Fantastic! I love that someone is applying the scientific method to pinball simulation!

 

These are the results from the current DX9 version (a bit ahead of Test4) on my laptop (Win7, GT 540M).

Quite erratic, isn't it? I have to find out if script events are processed every physics cycle or if there is some lag there to exclude that as a source of variation. After that, I will definitely use this test as a starting point when I get into the physics code to see how consistent I can get it.

[mukuste]

I made a small change to the physics code, forcing it to always run at a fixed timestep instead of trying to make shorter increments towards the end of a frame.

Much better! I wonder where the remaining variation comes from.

[toxie]

my suspicion is still numerical precision, and that due to this different heuristics are triggered in the code. but that's just speculation.

[gtxjoe]

The kicker holes cover about 4 degrees each so if the shot is between the two kickers, you will see it bin in both adjacent kickers. So it may not be flipper variance but rather the kicker is not in the right spot

Could probably calculate the ball angle when it hits a kicker and plot that data

But then they shouldn't sum up to 25, right? But they always do.

[gtxjoe]

I meant if the ball trajectory is between 2 kickers, the ball total will be split between those two kickers. No double hits

[mukuste]

Ah, ok, I see what you meant now. My hope was that the simulation would be stable enough to produce the exact same shot into the same kicker 25 out of 25 times. With my little physics mod that's still not quite true; it might be down to floating point accuracy, as toxie suggested, or there may be something else going on. In either case the variation seems low enough to be happy with I guess. Probably I should repeat the experiment and see if I get the exact same result.

[koadic]

Here is a variation of the test table which will report 2 different angles... the ball's angle of velocity when hitting the outside trigger, and the angle on the protractor that is hit. I copied the kickers and the flipper triggers from the original table, but I used a trigger instead of a bunch of kickers to increment the test and redid the scripting to use about 100 lines. Also, it only has two boxes for data display instead of the 125, but will report min/max/average of each triggers test as well as the angle reading for each ball.

Also, only a desktop version is available, but the backdrop settings can easily be altered if one wishes to use it on a cab.

Nice, koadic, that gives us even more data to play with.

 

Here are two full runs, once with vanilla physics and once with my mod. Again the results with the modded timestep are MUCH more consistent. Without mod, the Cradle 5 test was pretty catastrophic since one ball even failed to reach the triggers and went down the drain... I had to manually throw in a new one from the debug menu

Nice. Here is function for calculating Std Deviation.  I guess I won't be able to blame the VP flipper physics for my low scores anymore...

 

Function StdDev(sizeArr, Arr)

Dim i

Dim avg, SumSq

 

avg = Mean(sizeArr, Arr) 

For i = 1 To sizeArr 

SumSq = SumSq + (Arr(i) - avg) ^ 2 

Next

StdDev = Sqr(SumSq / (sizeArr - 1))

End Function 

 

Function Mean(sizeArr, Arr)

Dim Sum

Dim i

 

Sum = 0 

For i = 1 To sizeArr 

Sum = Sum + Arr(i) 

Next

Mean = Sum / sizeArr

End Function

Here's some more good news: I ran koadic's version a second time, again with the mod, and I got the same result. And by "same" I don't mean approximately, I mean the exact same numbers up to the fourth decimal digit.

 

So this proves that while there is a small amount of variance left, it doesn't depend on FPS anymore.

I'll just dump my latest results here, mostly for my own reference. Physics now run at 400Hz, friction and scatter disabled.

 

This is pretty much the holy grail in reproducibility, almost no variance left.

Physics 400Hz; no PF, wall, or flipper friction; scatter disabled

[faralos]

egads sir rocket scientists whatever happened to starting a game then just playing it?

 seems that pin playing is going too scientific if you ask me

[Slydog43]

wasn't the physics at 100hz before?  Have you made changes to the physics already in VP9.dx9 test?

[mukuste]

No, this is a private physics branch I started hacking on.
