dyn4j-samples
A collection of samples that use the dyn4j library in a variety of ways.
The intent of these samples is to provide a simple framework for building applications with the dyn4j library. The samples show how to use features like joints, static collision detection, raycasting, CCD, and so on. They also provide some creative ways to solve common problems like one-way platforms, jumping, destruction, player control, and so on. That said, none of these are intended to be complete solutions or even the correct solution for your use-case.
- All samples support zoom and pan using the mouse and mouse wheel
- All samples support object manipulation with the mouse
- All samples have features like reset, reset camera, toggle rendering, etc.
- Each sample may have it's own controls - see the console output when running for the full list of controls

BasketBall
Use angle, power, and position to attempt to make baskets. The sample only scores goals, so don't miss! If you are close you get 2 points, far away you get 3. Only if you get it in when you launch it is counted.
Billiards
Use the cue stick to hit the cue ball to hit the other balls. You must wait until the balls settle before your next hit.
Platformer
Use the ball to "run" around the level and jump. You can jump onto platforms above you no matter where you are, but if you land on them, they are solid. You can drop down from the top level as well. Green means you are touching the ground and can jump. Purple means you are not touching the ground.
Ragdoll
Use your mouse to drag around and contort the ragdoll
Tank
Drive a tank! Independently operating the tracks and barrel. The barrel will be pushed aside by obstacles. The barrel is "shooting" a ray to see what it would hit. You can press a key to destroy the closest object you are aiming at.
Thrust
How hard can it be to fly a rocket? Using only front, back and side thrusters (applied force) fly a rocket around an enclosed area. Challenge yourself to land without tipping over or flying in a smooth trajectory.
Truck
Drive a truck with cargo! Accelerate and decelerate using the keyboard or stop immediately. Watch the contents slide around as you drive. Use the mouse to manipulate the truck frame to see the suspension compress.
