　Drawing airplane animations

Private List<Bitmap> bitmaps = new ArrayList<Bitmap> ();

Add four images to the list

   Private  Feijiimage (Bitmap my) {            this.my=my;            Bitmaps.add (Bitmap.createbitmap (My,0,0,my.getwidth ()/4,my.getheight ());            Bitmaps.add (Bitmap.createbitmap (My, (My.getwidth ()/4), 0,my.getwidth ()/4,my.getheight ());            Bitmaps.add (Bitmap.createbitmap (My, (My.getwidth ()/4) *2,0,my.getwidth ()/4,my.getheight ());            Bitmaps.add (Bitmap.createbitmap (My, (My.getwidth ()/4) *3,0,my.getwidth ()/4,my.getheight ());            Get the fighter's high and wide            width=my.getwidth ()/4;            Heigth=my.getheight ();            X= (Display_w-my.getwidth ()/4)/2;            Y=display_h-my.getheight () -30;        }

Public static Bitmap CreateBitmap (Bitmap source, int x, int y, int width, int height, Matrix m, boolean filter)
cutting an image from the original bitmap is an advanced way. You can use matrix to achieve advanced methods such as rotation
Parameter Description: Portal
Bitmap Source: The original bitmap from which to
int x: starting x coordinate
int y: start y coordinate
int Width: The width of the graph to be truncated
int Height: The width of the graph to be truncated
bitmap.config Config: A configuration of an enumeration type that can define the quality of the new bitmap that is truncated
Return value: Returns a cut-bitmap

　

　

draw an airplane flight animation (constantly switch four pictures, look like a plane fly)

Public Bitmap Getbitmap () {            Bitmap Bitmap = bitmaps.get (index);            Control the frequency of switching four aircraft           if (num = = ten) {               index++;               if (index = = bitmaps.size ()) {                   index=0;               }               num=0;           }            num++;            return bitmap;        }

For non-conflicting background movement and airplane flight speed, the airplane picture toggles 10 times times slower background image movement

Registering an airplane in a game event follows its own finger movement event

    Public Dafeijigameview (Context context) {        super (context);        Getholder (). Addcallback (this);        Event Registration        This.setontouchlistener (this);    }

　　Realizing that the airplane follows its own finger movement

Feijiimage Selectfeiji; @Override public boolean OnTouch (View V, motionevent event) {//hand near screen-generated event if (Event.getaction () ==motionev Ent.                    Action_down) {for (Gameimage game:gameimage) {if (game instanceof Feijiimage) {                    Feijiimage Feiji = (feijiimage) game; Select the aircraft if the condition is true (Feiji.getx ()<Event. GetX () && feiji.gety () <event.gety () && FEIJI.G EtX () +feiji.getwidth ( )>event.getx () && feiji.gety () +feiji.getheigth () >event.gety ())                    {Selectfeiji=feiji;                    }else{Selectfeiji=null;                } break; }}}else if (Event.getaction () ==motionevent.action_move) {//Move mouse if (selectfeiji!=                NULL) {selectfeiji.setx (int) event.getx ()-selectfeiji.getwidth ()/2);            Selectfeiji.sety ((int) event.gety ()-selectfeiji.getheigth ()/2);        }}else if (Event.getaction () ==motionevent.action_up) {//release mouse selectfeiji=null;    } return true; }
