FantomMappy v1.0.6


Written in: Fantom pod: v1.0.6 Licence: MIT

Overview

FantomMappy is a playback library for rectangular, hexagonal and isometric tile maps created with Mappy.

Mappy Screenshot

Use Mappy to create your maps, then use FantomMappy to embedd them in your games / applications.

Install

Install FantomMappy with the Fantom Repository Manager ( fanr ):

C:\> fanr install -r http://pods.fantomfactory.org/fanr/ afFantomMappy

To use in a Fantom project, add a dependency to build.fan:

depends = ["sys 1.0", ..., "afFantomMappy 1.0"]

Documentation

Full API & fandocs are available on the Fantom Pod Repository.

Quick Start

  1. Create a text file called Example.fan

    using gfx
    using fwt
    using web
    using afFantomMappy
    
    class Example {
        Void main() {
            fmaBuf  := WebClient(`http://static.alienfactory.co.uk/fantom-docs/alienEpidemic.fma`).getBuf
            pngBuf  := WebClient(`http://static.alienfactory.co.uk/fantom-docs/alienEpidemic.png`).getBuf
            pngFile := File.createTemp("alienEmdemic", "png").deleteOnExit
            pngFile.out.writeBuf(pngBuf).close
    
            map      := MapLoader.loadMap(fmaBuf.in)
            blocks   := Image(pngFile)
            renderer := FmaRenderer(map.mapHeader, blocks, true)
            canvas   := MappyCanvas(map, renderer)
    
            animate  := (Func?) null; animate = |->| {
                canvas.animate
                canvas.repaint
                Desktop.callLater(30ms, animate)
            }
    
            Window(null) {
                it.resizable = false
                it.title     = "Alien Epidemic"
                it.size      = Size(320, 240)
                it.content   = canvas
                it.onOpen.add(animate)
            }.open
        }
    }
    
    class MappyCanvas : Canvas {
        private MappyMap    map
        private Renderer    renderer
        private Int         speedX    := Int.random(1..4)
        private Int         speedY    := Int.random(1..4)
    
        new make(MappyMap map, Renderer renderer) {
            doubleBuffered  = true
            this.map        = map
            this.renderer   = renderer
        }
    
        Void animate() {
            mapViewer.updateAnimBlocks
            viewer := mapViewer.layerViewers[0]
            viewer.translatePixels(speedX, speedY)
    
            if (viewer.coorInPixels.x < 0) {
                speedX = -speedX ; viewer.translatePixels(speedX, 0)
            }
            if (viewer.coorInPixels.x >= (mapViewer.mapHeader.mapSizeInPixels.w - size.w)) {
                speedX = -speedX ; viewer.translatePixels(speedX, 0)
            }
            if (viewer.coorInPixels.y < 0) {
                speedY = -speedY ; viewer.translatePixels(0, speedY)
            }
            if (viewer.coorInPixels.y >= (mapViewer.mapHeader.mapSizeInPixels.h - size.h)) {
                speedY = -speedY ; viewer.translatePixels(0, speedY)
            }
        }
    
        once MapViewer mapViewer() {
            mapViewer := MapViewer(map, renderer, Rect(Point.defVal, size))
    
            x := Int.random(0..<map.mapHeader.mapSizeInPixels.w - size.w)
            y := Int.random(0..<map.mapHeader.mapSizeInPixels.h - size.h)
            mapViewer.coorInPixels = Point(x, y)
    
            return mapViewer
        }
    
        override Void onPaint(Graphics g) {
            g.brush = Color.black
            g.fillRect(0, 0, size.w, size.h)
            mapViewer.draw(g)
        }
    }
    
  2. Run Example.fan as a Fantom script from the command line:

And you should see a window with an animated map:

FantomMappy QuickStart Example

Usage

Most of the QuickStart example is fwt code, the actual FantomMappy usage is quite simple.

Use MapLoader to load the Mappy .fmp or .fma files:

map := MapLoader.loadMap(inStream)

Create a Renderer that will render the block images:

renderer := FmaRenderer(map.mapHeader, blockImage, true)

Use a Viewer to view the map, usually you would render it to an fwt Canvas. You can use a MapViewer or a LayerViewer.

mapViewer := MapViewer(map, renderer, Rect(x, y, w, h))
mapViewer.draw(g)

And that's about it.
