Android Question Rnd function gives upper half of numbers only

swabygw · Feb 1, 2024

Please consider following code:

B4X:

' the initializer: noteTimer.Initialize("noteTimer", 1)

Sub noteTimer_Tick()
    
    'ThisBeatTime = DateTime.Now
    Dim DTN As Long = DateTime.Now
    Dim BPM As Int = GetBPM
    Dim TIM As Int = 60000 / BPM
    Dim ERROR_ADJUSTMENT As Int = 25 'arbitrary value to compensate for inaccurate ticker
    
    If DTN >= ((LastBeatTime - ERROR_ADJUSTMENT) + TIM) Then
        '--------------------------------------
        ' Looping characteristics
        '--------------------------------------
        errorTime = DTN - (LastBeatTime + TIM)
        Log("#" & currentKeyCount & ", ErrorTime: " & errorTime & ", DTN: " & DTN & ", LastBeatTime: " & LastBeatTime & ", BPM: " & BPM & ", TIM: " & TIM)
        LastBeatTime = DTN - errorTime

    End If
    
End Sub

Sub GetBPM As Int
    
    Dim BPM_Out As Int
    
    Try
        
        'BPM_Out = lbl_Rate.Text
        
        'If rsb.SelectedMaxValue <> rsb.SelectedMinValue Then
            'BPM_Out = Rnd(rsb.SelectedMinValue, (rsb.SelectedMaxValue + 1))
            BPM_Out = Rnd(1, (100 + 1))
            'Log("BPM: " & BPM_Out)
        'End If
        
    Catch
        Log(LastException)
    End Try
    
    Return BPM_Out
    
End Sub

...produces BPM_Out always between 70 and 100, even though it should be picking between 1 and 100. Why wouldn't there be any random number generated below 70? Is there an error in the initialization maybe?

That was it. I moved the TIM declaration to Globals, added "TIM = (60000 / GetBPM)" inside of the loop (instead of before the loop), and it worked better.

I tried your code and seems fine to me. I get all kind of values for BPM:

How about adding RndSeed ?

B4X:

RndSeed(DateTime.Now)
BPM_Out = Rnd(1, 101)

Using RndSeed is a little different. Its main purpose is to obtain the same sequence of random values at each execution of the software; this is useful for debugging the project.
When your project is ready to publish, you delete RndSeed.

aeric · Feb 1, 2024

I don't agree.

Yes if you set a fixed value

B4X:

RndSeed(36)

but No if the value of seed is different every time

B4X:

#If RELEASE
Log("== RELEASE ==")
#Else
Log("** DEBUG **")
#End If
'Dim Seed As Long = 36
Dim Seed As Long = DateTime.Now
Log($"Seed=${Seed}"$)
RndSeed(Seed)
For i = 0 To 9
    Log( Rnd(1, 101) )
Next

It doesn't matter whether I am compiling in Debug or Release.

Okay I get what you mean now.

Randomize in b4a

Hi I tried to set an int to a random number, but always when I run the app, the value of the randome int is the same number overband over again. In Vb before setting a random value, there is a command - 'randomize' There is a way that the random number will be not the same any time?

www.b4x.com

It is only required if we need a fix sequence of random numbers. Otherwise it does nothing.

edit: Unless it is for OCD like me ?

The random number displayed in the Log on line 34 of the code shows random numbers, indeed, but the BPM seems to always be selecting the higher values. Could it be the timing of the loop condition on line 11 ("If DTN >= ((LastBeatTime - ERROR_ADJUSTMENT) + TIM) Then")? I was thinking that, maybe, because the GetBPM is before the looping condition, it changes the threshold needed to enter the loop, as a result (i.e., the TIM variable becomes a higher threshold)...not sure. Here's another output that demonstrates the strange behavior. It's a bit long but shows the random numbers, indeed, being generated but, coincidentally or not, the higher number just happens to be at the time of the entering of the loop:

I think it is better you upload a sample project.

I think I know the problem. It is the TIM variable. Because it's a division, the result can be very high (e.g., 60000 / 1 = 60000) which then makes the threshold to enter the loop too high when the BPM_Out is too low. So the BPM_Out must be high, to get a low TIM and enter the loop, thus, the higher BPM's process in the loop. The occurrence is still random, but the probability of entering the loop is significantly better with the higher BPM_Out and DTN which are both regenerated at each 1 tick. I think the solution is to get the random number once and wait until the DTN reaches it, at each round, instead of getting a new random number at each tick.

swabygw · Feb 1, 2024

That was it. I moved the TIM declaration to Globals, added "TIM = (60000 / GetBPM)" inside of the loop (instead of before the loop), and it worked better.
