This document summarizes a presentation by Richard and Jasper from Sun Microsystems on gaming with JavaFX. The speakers are core engineers on JavaFX who will demonstrate physics demos using APIs like Box2D. They will show how to integrate physics into JavaFX scenes using a PhysicalScene and PhysicalObjects with physics bodies. The demos will apply concepts like gravity and initial velocity. JavaFX's new graphics stack called Prism is introduced as well, which replaces AWT and allows straight hardware access for performance. The presentation aims to show that JavaFX 1.2.1 is ready for games and encourages developing apps for the Java Store.

Stop hitting me!
Hit (collision) detection is expensive
Broad phase uses AABB (axis aligned bounding box) and
tricks to trivially reject
Narrow phase performs hit detection on the geometry
Not dissimilar to how we do picking in JavaFX

Physics Integration
PhysicalScene
A Scene which contains a physics World
Gravity
Dampening / Iterations
PhysicalObject
A Node which has a physics Body
And a Body has a (non-fx) shape as geometry

This is Heavy Stuff Dude
Apply Gravity to Scene
Setup Body objects
Physics Engine does the rest

Watch where yer goin eh!
Same demo as before, but this time with an initial
velocity
b.adjustVelocity(new Vector2f(10000, 0));

17. www.devoxx.com
Prism
Internal working name for new graphics stack
Replaces AWT
Straight to the hardware (OpenGL or Direct3D)
Really Fast

Summary
JavaFX 1.2.1 is Game Ready
Write some apps for the Java Store
Have some fun, make some $$
Using Java APIs from FX is easy
