How to realize gluttonous Snake Game with Java
This article introduces the relevant knowledge of "how to use Java to achieve gluttonous snake game". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
1. Execution program: the entrance to the startup of the program
Package cn.hncu
Public?class?GreedySnake {
Public static void main (String [] args) {
Model model=new Model (80 and 50)
Control control=new Control (model)
View view=new View (model,control)
Model.addObserver (view)
(new Thread (model)) .start ()
}
}
Control class: mainly for keyboard keystroke collection and transmission
Package cn.hncu
Import java.awt.event.KeyEvent
Import java.awt.event.KeyListener
Public class Control implements KeyListener {
Model model
Public Control (Model?model) {
This.model=model
}
Public void keyPressed (KeyEvent?e) {
/ / this method collects buttons
Int key=e.getKeyCode ()
If (model.running) {
Switch (key) {
Case KeyEvent.VK_UP:
Model.changeDirection (model.up)
Break
Case KeyEvent.VK_DOWN:
Model.changeDirection (model.down)
Break
Case KeyEvent.VK_LEFT:
Model.changeDirection (model.left)
Break
Case KeyEvent.VK_RIGHT:
Model.changeDirection (model.right)
Break
Default:
Break
}
}
If (key==KeyEvent.VK_ENTER) {
Model.reset ()
}
}
Public void keyReleased (KeyEvent?e) {
}
Public void keyTyped (KeyEvent e) {
}
}
Model class: the implementation of creating snake bodies and snake movements, using threads.
Import java.util.Arrays
Import java.util.LinkedList
Import java.util.Observable
Import java.util.Random
Import javax.swing.JOptionPane
Public class Model extends Observable implements Runnable {
Public static final int left=1
Public static final int up=2
Public static final int right=3
Public?static?final?int?down=4
Public?boolean?coordinate [] []; / / use this as the coordinates of the interface
Public?LinkedList?node=new?LinkedList ()
Public?int?direction=2
Boolean?running=false
Public?int?maxX,maxY
Node?food
Public?int?sleeptime=200
Public?Model (int?maxX,int?maxY) {
This.maxX=maxX
This.maxY=maxY
Reset ()
}
Public?void?reset ()? {
Direction=this.up
Sleeptime=200
Coordinate=new?boolean [maxX] []
For? (int?i?=?0;?i?
