Monkey-X - Beginners - Binary Addition - code example

' Adding binary up - getting every combination

Import mojo

' How long should the binary be
Global binlen:Int=14
' This contains the binary data. bin[0] is the most left
Global bin:Int[]

Class MyGame Extends App
    ' keep track of the number
    Field cnt:Int=0
    Method OnCreate()
        ' create our binary array
        bin = New Int[binlen]
    End Method
    Method OnUpdate() 
        If KeyHit(KEY_SPACE) Or MouseHit(MOUSE_LEFT) 
            ' Add one to the binary
            ' Add up one into our count
           End If
    End Method
    Method OnRender()
        Cls 0,0,0 
        SetColor 255,255,255
        Scale 2,2
        DrawText "Press Space or LMB(touch) to increase",0,0
        ' Draw the binary on the screen
        For Local i:Int=0 Until binlen
            DrawText bin[i],i*20,100
        DrawText cnt,0,120
    End Method
End Class

'We go from right to left turning each 1 into a zero until
'or if we find a 0 and then we then turn this into a 1 and then return
Function incbin()
    ' Loop from right to left
    For Local i:Int=binlen-1 To 0 Step -1
        ' if we encounter a 0 then turn it into a 1 and return
        If bin[i] = 0 Then 
            bin[i] = 1
