Random Integer Code?

[niffirg1]

So i need a code that can give me a random integer. So i did some research and i found a code on Phunland Forums but sadly it didn't work. So do any of yall know how to spawn a random integer that is between two numbers and i whole not 5.634141....1341324 and so on?

[RA2lover]

spawn something without speciying color, then read that color for the number. then you canuse multiplications and such for giving that random number area you want.

[niffirg1]

What do you mean by canuse multiplications?

[Sonic]

He means you could multiply the numbers together to make a random random number.
Or you could use this site.

Do you need it for Algodoo or just for something in real life?

[RA2lover]

the multiplication was just for determining range.

in normal spawning, it ranges between 0 and 1

so, the formula for giving that range would be

minimum range + [random number * (maxrange-minrange)]

if you want an integer, use math.toint(scene.my.randnumberresult)

[Sonic]

Ahh, but is it truely random? Remember, no human generated number is truely random.

[RA2lover]

and no nature-generated number is truly random. butterfly effect FTW!

[Sonic]

To get a truly random number, you have to do something with isotopes. I don't remember exactly what.

[KarateBrot]

I once made a random function for algodoo.
It produces random float numbers from min to max. Like RA2lover already said, use math.toInt( scene.my.random(min, max) ) to make random integer values.

Code: Select all

scene.my.memory = 17;

scene.my.random = (min, max)=>
{
      x := scene.my.memory;
      m := 1249 * 373;
      x = x ^ 2 % m;
      x == 0 ? {scene.my.memory = x + 1} : {scene.my.memory = x};
      x * (max - min) / (1249 * 373.0) + min
}


btw. it's no real randomness. No computer algorithm can produce real random numbers. But it's very good so even if you playback the exact same scene with scene.my.random in parallel you can't see any equalities between the "random" numbers.

There's quantum randomness. Some quantum-based processes, like radioactive decay are truely random. Decay counting detectors are used in cryptography to get really random numbers.

[Sonic]

I actually saw a book of a millon random numbers. Some people have too much time on their hands.

[RA2lover]

no numbers are random. if quantum decay would be random, then THROW AWAY THE ATOMIC CLOCKS!!!!1111eleven!one!!!!11

atomic clocks don't work with nuclear disintegration. time is derived with the frequency of photons that are emitted when isotops (mainly of cesium) change their energy state(?) (i don't know the exact english word for this)

[Sonic]

I'm no nuclear physiscist, but I but I beleive you mean when they "decay."

[KarateBrot]

yeah i don't know the correct english word so maybe "nuclear disintegration" is wrong but with "energy state" i don't mean "decay". i mean when electrons in an atom spontaneously give away energy

Can someone tell me if Math.toInt is supposed to work in Phun?
And if not, what's the sinplest solution?

[Mystery]

Nope it doesn't work in phun.

Code: Select all

scene.my.round = (x) => {(math.mod (x,1) < .5) ? (x - math.mod (x,1)) : (x - math.mod (x,1) + 1)}
scene.my.int10 = (x) => {X==0 ? 0 : X==1 ? 1 : X==2 ? 2 : X==3 ? 3 : X==4 ? 4 : X==5 ? 5 : X==6 ? 6 : X==7 ? 7 : X==8 ? 8 : X==9 ? 9 : 9}
Scene.my.float2int := (f)=>{f < 9.5 ? scene.my.int10(scene.my.round(f)) : {scene.my.float2int(f / 10) * 10 + scene.my.int10(math.mod(scene.my.round(f), 10))}}
infix 1 right: #_ => scene.my.float2int;

//now try:

12.444 / 5
// gives 2.4888

#12.444 / 5
// gives 2

Or you can be creative and invent a better one.

randomness has nothing to do with the actual possibility of prediction but rather if the observer can predict it so while you could predict a roll of dice with a bunch of cameras, sensors and a supercomputer if you dont then the roll of dice is for all intents and purposes - random. if you wanna be extra sure that no human can predict(yet) the outcome you basically have to hook a geiger counter to a barrel of plutonium, done!
for algodoo however random=(scene.addcircle()).color(0)

Now this is one random Thread reopening........

Your code isn't working good, a-a-a... it isn't working at all.
working code

Code: Select all

random=(scene.addcircle({density:=0})).color(0)

Nope i don't see it.

If you clone a circle 100 times upon itself what's deciding whether wich way each circle should go??(always wondered that )
