Monkey-X - inloop class creation and creating 2 dim array (meth) - code example

Here a example of how to remake classes in the main loop. This is done with a map class. Also a example of how to set up the map array in the class and creating that with a

method.

Import mojo

Class map
    Field mapwidth:Int,mapheight:Int
    ' the 2 dimensional array i set up here
    ' it needs no size yet.
    Field map:Int[][]
    Field tilewidth:Float,tileheight:Float
    Method New(mapwidth:Int,mapheight:Int)
        ' here we resize the map array
        map = makearray(mapwidth,mapheight)
        Self.mapwidth = mapwidth
        Self.mapheight = mapheight
        tilewidth = 640/mapwidth
        tileheight = 480/mapheight
        makemap
    End Method
    Method makemap() 'create random blocks
        For Local i=0 Until (mapwidth*mapheight)/10
            map    [Rnd(0,mapwidth)][Rnd(0,mapheight)] = 1
        Next
    End Method
    Method draw()
        For Local y=0 Until mapheight
        For Local x=0 Until mapwidth
            If map[x][y] = 1
                SetColor 150,150,150
                DrawRect     x*tilewidth,
                            y*tileheight,
                            tilewidth,tileheight
                            
            End If
        Next
        Next
    End Method
    ' this function creates and returns a 2
    'dimensional array
    Method makearray:Int[][](a:Int,b:Int)
        Local aa:Int[a][]
        For Local i=0 Until a
            aa[i] = New Int[b]
        Next
        Return aa
    End Method    
End Class
