GroupPickRandomUnit isn't so random.

[cleeezzz]

set Hero[GetPlayerId(p)] = GroupPickRandomUnit(g)

this code always returns the same unit out of a group of 6 units, fixed random seed is UNCHECKED. workaround?

 

[Azlier]

Set every unit in the group into a unit array and use Random Integer to get one?

 

[cleeezzz]

i was hoping it would be easier, i mean, thats what a groupickRANDOMunit is for =/, whats the point of that function if its not even random -.- (between games)

Create your own and submit it as a snippit.

GroupPickRandomUnit uses GetRandomInt. Test it out in a game rather than through test map, and see if it is any different.

 

[cleeezzz]

set g = NewGroup()
            call GroupEnumUnitsInRect( g, bj_mapInitialPlayableArea, Condition(function PrivateFilter))
            set c = CountUnitsInGroup(g)
            loop
                exitwhen i == c
                set RandomHero<i> = FirstOfGroup(g)
                call GroupRemoveUnit(g,RandomHero<i>)
                set i = i + 1
            endloop</i></i>

omg. its still not random, argh

i thought unchecked fixed random seeds fixed this.

 

[AceHart]

Why would it? It's not using any "random"...

 

[cleeezzz]

my bad, didn't copy full trigger,

set g = NewGroup()
            call GroupEnumUnitsInRect( g, bj_mapInitialPlayableArea, Condition(function PrivateFilter))
            set c = CountUnitsInGroup(g)
            loop
                exitwhen i == c + 1
                set RandomHero<i> = FirstOfGroup(g)
                call BJDebugMsg(I2S(i))
                call BJDebugMsg(GetUnitName(RandomHero<i>))
                call GroupRemoveUnit(g,RandomHero<i>)
                set i = i + 1
            endloop
            call ReleaseGroup(g)
            set r = GetRandomInt(1,c)
            call BJDebugMsg(I2S(r))
            set Hero[GetPlayerId(p)] = RandomHero[r]</i></i></i>

r always returns 5 for some reason (at least 4 in a row)
if it IS random, imma go buy a lotto ticket. -.-

 

[cleeezzz]

bump, its not random. or will it be random when played out of test?

 

[Builder Bob]

4/5 is unlikely, but it is not a proper test.

Here's a test map for the function GroupPickRandomUnit(). What are your results? Is the function really not random on your computer? It gives the expected randomization when I test it.

 

[cleeezzz]

its random, but i dont know why, it doesn't seem to be random in my map.

i get 5 every time

 

[Builder Bob]

That's just weird... From the code you posted I'd expect your debugging to show a random number of all the numbers being run through the loop.

 

[cleeezzz]

well, its random AFTER the first run, but first run always returns 5 lol

 

[Gwypaas]

Maybe it uses an internal value that changes after every use if "GetRandomInt" so, the first is always the same but after that then it uses ingame parameters to calculate it.

Just a thought.

 

[emjlr3]

if your using test map - its always going to be the same during the first test - load the game individually from TFT and try again

And this from our very own Hulk3...
There's the "use fixed seed" option in "preferences", just for that.

And, with the exception of cleeeeeeeez' map, that option works just fine.

Should it be checked or not ? I have it checked, and it does not seem to affect to GetRandomInt.

Correction:
And, with the exception of cleeeeeeeez' map and uber's map, that option works just fine.


Unchecked.

who knew...

please download this map and then as player one, type -ffa, then type -save, and then copy the code into the chat box. ex: -load HIH-IHI

then wait until the building finishes, do not select a hero or else it will not random. when it finishes building and you get a hero other than Illusionist, please tell me.
