Flying Java 3D_3

To detect a collision, I added an inner class, in the following code CollisionDetectorGroup, to the Mykeynavbeh class.

The CollisionDetectorGroup class extends the Behavior class, so it has the processStimulus method, which can be executed when the wakeup condition is satisfied.

Within the method, you can write code for making the object bounce back, making a sound, or whatever you like.

Mini-games can be created using the above classes, but to make cool programs, you need something more.

Within the processStimulus method of the CollisionDetectorGroup class, you can write code for reading a .wav file to play a sound.

Also, after a .mid file is read, you can toggle music on and off by pressing a key.

If you change a crash sound file to a voice file, you can create a program where a character can speak when you type a string from the keyboard.

Using the Switch and BitSet classes, you can make a 3D version of a flip book. The bits in a BitSet are indexed like this: By default, all bits are set to false. 

When you set a certain bit to true, only the corresponding child connected under a Switch becomes visible. For example, if you set bit 0 in a BitSet to true, the first child under a Switch becomes visible.

The light comes from the side:

A shadow is created using OrientedShape3Ds with shadow images. When a model is rotated, the images are switched.

Using the code like this:

speed += 0.01f;

speed -= 0.01f;

accelerates or decelerates a moving object.

If an object, for example a car, is positioned like this:

the code like this:

speed -= 0.01f; 

accelerates the car.

If acceleration and deceleration are applied to the y-axis direction, an object flies through the air and follows a parabolic path.

I could fly if I had wings. If you are always thinking about that, try the followings:

To make an object move on the surface of a sphere,

the followings are needed:
