Quite often only the upper 16 bits of the 32 bit position is set, leaving the fractional part unaltered. This will generate a degree of randomness.

One visible example of this is sometimes the ball on the penalty spot will slowly roll away if you leave it long enough! Only the upper part of the velocity is zeroed.


Wow! This is impressive.

BTW, your 4.3 billion number was just a figure of speech, right?

Remember Einstein's "God does not play dice with the Universe" quote?

This was a topic of some of Bohr and Einsteins Copenhagen talks. Einstein didn't believe in quantum effects. He was wrong.

I'd say not.

He said that the lower 16 bits don't get cleared. If you apply that to the X and Y position, then you have a variance of 65536x65536 which comes to 4,294,967,296. As near as dammit 4.3 billion.

I know, i'm a progr too, but this says that there are so much combination of situations per pixel per move per push ......... that wind is not needed :D

Can we reduce this randomness please. I favour a more robotic game.

Nope with inventapizza you get a choice. Inventaresult is totally random!

I want to point out an another random factor in the KO2 code.
I'm sure that all off you "feel" that sometimes happens strange things in KO2. sometimes happens that you makes a move that you already made hundreds times but:" f**k, in this game it doesn't run!".

I'm sure that there is a random factor that infuences the control in game.




2 when ball is placed on centre spot. It's given some horizontal velocity


Seems that we have the reason... a sort of mini horizontal light wind...
Damn, my dream is indoor kickoff2 pitch... nothing that pollutes the ball control...

I know that, also this is applied on free kicks and penalty kicks, if you wait some minutes you'll see the ball slowly move pixel after pixel.

You can also wait till the ball move into goal, it'll take a couple of hours but it's a 100% goal (ask to Gunther :lol: )
