Monkey-X - Screen Wipe method 3 - code example


Here another way to wipe the screens inbetween scenes.

Code below :

Import mojo

Class map
    Field tilewidth:Int,tileheight:Int
    Field mapwidth:Int,mapheight:Int
    Field map:Int[][]
    Field bwipe:Int[10]
    Field wipeactive:Bool=False
    Field wipemode:String
    Method New(mapwidth:Int,mapheight:Int,tilewidth:Int,tileheight:Int)
        Self.tilewidth = tilewidth
        Self.tileheight = tileheight
        Self.mapwidth = mapwidth
        Self.mapheight = mapheight
        map = New Int[mapwidth][]
        For Local i = 0 Until mapwidth
            map[i] = New Int[mapheight]
        Next
        For Local y=0 Until mapheight
        For Local x=0 Until mapwidth
            setmap(x,y,Rnd(0,5))
        Next
        Next
    End Method    
    Method update()
        If wipemode = "wipeout"
            For Local i=0 Until 10
                If bwipe[i] < 64 Then bwipe[i] +=2
            Next
            If bwipe[0] > 63 Then wipemode="black"
        End If
        If wipemode = "wipein"
            For Local i=9 To 0 Step -1
                If bwipe[i] > 0 Then bwipe[i] -= 2
            Next
            If bwipe[9] <= 0 Then wipemode="nothing"
        End If
    End Method
