Android Combat Aircraft Game Menu Page Design (1) _android

This article aims to achieve control of small aircraft moving around, dodge bullets, hit boss.

This section implements the Start menu interface

1. First of all, the resource files are handcuffed.

2. Divide the game status

 public static final int game_menu = 0;//Game Menu public
 static final int gameing = 1;//game public
 static final int G Ame_win = 2;//Game victory public
 static final int game_lost = 3;//game failure public
 static final int game_pause = -1;//Game Menu c6/>//Current game state (default initial in Game menu interface) public
 static int gamestate = Game_menu;

Define five states

After the method is defined in the drawing method, the entity key presses the method, raises the method, touches the screen to monitor, the logical method, the switch

In those ways add this

  switch (gamestate) {case
  game_menu: Break

   ;
  Case gameing: Break
   ;

  Case Game_win: Break

   ;
  Case Game_lost: Break

   ;
  Case Game_pause: Break
   ;
  Default: Break
   ;
  }

Here's another statement.

Declare a resources instance to facilitate loading pictures
 Private Resources res = this.getresources ();
 Declare the game needs to use the picture resources (picture statement)
 Private Bitmap bmpbackground;//game background
 private Bitmap bmpboom;//explosion effect
 private Bitmap Bmpboosboom;//boos explosion effect
 private Bitmap bmpbutton;//game start button
 Private Bitmap bmpbuttonpress;//Game Start button is clicked
 Private Bitmap bmpenemyduck;//Monster Ducks
 private Bitmap bmpenemyfly;//monster flies
 private Bitmap bmpenemyboos;//monster pig head boos
 Private Bitmap bmpgamewin;//game victory background
 private Bitmap bmpgamelost;//game background
 private Bitmap bmpplayer;// Game lead airplane
 private Bitmap bmpplayerhp;//lead airplane blood volume
 private Bitmap bmpmenu;//menu background public
 static Bitmap bmpbullet;//bullets public
 static Bitmap bmpenemybullet;//enemy bullets public
 static Bitmap Bmpbossbullet;//boss Bullets

 /** * Load game resource/private void Initgame () {//load game Resource Bmpbackground = Bitmapfactory.decoderesource (res, R.DRAWABLE.BAC

Menu Class Gamemenu

Menu class
Includes initializing drawing buttons and background images

Package COM.GSF;
Import Android.graphics.Bitmap;
Import Android.graphics.Canvas;
Import Android.graphics.Paint;

Import android.view.MotionEvent;
 /** * * @author liuml * @time 2016-5-27 PM 5:43:34/public class Gamemenu {//menu background map private Bitmap bmpmenu;

 button to press the identity bit private Boolean ispress;
 The menu initializes public gamemenu (Bitmap bmpmenu, Bitmap Bmpbutton, Bitmap bmpbuttonpress) {this.bmpmenu = Bmpmenu;
 This.bmpbutton = Bmpbutton;
 this.bmpbuttonpress = bmpbuttonpress;
 X is centered, Y is immediately at the bottom of the screen btnx = MYSURFACEVIEW.SCREENW/2-Bmpbutton.getwidth ()/2;
 Btny = Mysurfaceview.screenh-bmpbutton.getheight ();
 Ispress = false;
 public void Draw (Canvas Canvas, Paint Paint) {//Draw menu background Image Canvas.drawbitmap (bmpmenu, 0, 0, Paint);
 if (ispress) {Canvas.drawbitmap (bmpbuttonpress, Btnx, Btny, paint);

 else {canvas.drawbitmap (Bmpbutton, Btnx, Btny, paint); }} public void OnToUchevent (Motionevent event) {//get current touch position int pointx = (int) event.getx ();

 }
  }

Then use the Gamemenu in the Mysurfaceview to use the menu class
