An side-scrolling game attempt.

I used two images, this mountain background made with Gimp (xcf sources here) and that ship above made with Inkscape (svg sources here).

import javafx.ui.*;
import javafx.ui.canvas.*;

var scroll;
scroll = [1..800] dur 60000 linear continue if true;

var mountains = Clip{
    transform: bind translate(-scroll,0)
    shape: Rect {x:bind scroll, y:0, width:400, height:200}
    content: [ImageView {
            transform: translate(0,0)
            image: Image { url: "http://silveiraneto.net/downloads/mountains.png"}
        },
        ImageView {
            transform: translate(800,0)
            image: Image { url: "http://silveiraneto.net/downloads/mountains.png"}
        }
    ]
};

var h = 50;

var ship = ImageView {
    cursor: HAND
    transform: bind translate(0,h)
    image: Image { url: "http://silveiraneto.net/downloads/jfx_plane.png"}
    onMouseDragged: operation(e) {
        h += e.localDragTranslation.y;
    }
};

Canvas {
    content: [mountains, ship]
}

An simple color picker that can be also used as a gadget.

import javafx.ui.*;
import javafx.ui.canvas.*;

var colors = [red:Color, orange:Color, yellow:Color, green:Color,
     cyan:Color,blue:Color, magenta:Color, gray:Color];

var chosenColor: Paint;
chosenColor = black:Color;

var x = 120;
var y = 70;

Canvas{
    content: Group{
        transform: bind translate(x,y)
        content: [Star{
            points: sizeof colors
            rin: 30
            rout: 50
            fill: bind chosenColor
            onMouseDragged: operation(e) {
                x += e.localDragTranslation.x;
                y += e.localDragTranslation.y;
            }
        },
        foreach (i in [1..sizeof colors]) Circle {
            var: self
            transform: [rotate(i*360/sizeof colors,0,0), translate(50,0)]
            radius: 10
            fill: colors[i%sizeof colors]
            onMouseClicked: operation (e){
                chosenColor = self.fill;
            }
        }]
    }
}

Two simple JavaFX code handling onMouseDragged event.

import javafx.ui.*;
import javafx.ui.canvas.*;

Canvas {
    content: Circle {
        var x = 50
        var y = 50
        transform: bind translate(x, y)
        radius: 30
        fill: red
        onMouseDragged: operation(e) {
                x += e.localDragTranslation.x;
                y += e.localDragTranslation.y;

        }
    }
}

import javafx.ui.*;
import javafx.ui.canvas.*;

Canvas {
    content: Circle {
        var x = 50
        var y = 50
        var radius = 30
        transform: bind translate(x, y)
        radius: bind radius
        fill: red
        onMouseDragged: operation(e) {
            if (e.button == 1){
                x += e.localDragTranslation.x;
                y += e.localDragTranslation.y;
            }
            if (e.button == 3) {
                radius += e.localDragTranslation.x;
            }
        }
    }
}

import javafx.ui.*;
import javafx.ui.canvas.*;

Canvas {
    content: [
    Rect {x: 50, y: 50, width: 50, height: 50, fill: orange },
    Circle {
        var x = 50
        var y = 50
        var radius = 30
        var color = red:Color
        transform: bind translate(x, y)
        radius: bind radius
        fill: bind color
        onMouseDragged: operation(e) {
            if (e.button == 1){
                x += e.localDragTranslation.x;
                y += e.localDragTranslation.y;
            }
            if (e.button == 3) {
                radius += e.localDragTranslation.x;
            }
        }
        onMousePressed: operation(e){
            color = Color {blue: 0.0, green: 0.0, red: 1.0, opacity: 0.5};
        }
        onMouseReleased: operation(e){
            color = red:Color;
        }
    }]
}

You can test this examples with thhe JavaFX Pad or using Netbeans with the JavaFX Plugin.

Disclaimer: from now on I will occasionally post in English too.

A first release of an Wheel of Fortune made with JavaFX. There’s still has a lot of bugs but is already usable. Let’s say that version is 0.8.
