Collect money bags for Android games (homemade)

I am interested in this piece of the game, just to learn Android, so I learned to do the next Android game

This article is my own study and record, like people can read, write bad don't spray

At first, the basics of Android and the environment are not in the detail, the basic analysis of the game:

Required elements: Money and money Bag Board

Little game, just a few tests of the function, so did not do well,

The reason that the individual likes to play the game is because the game and the real world are very close, can use the realistic thought to think the game

For example, the game: first of all, money is definitely the default in the case of non-stop movement, and then the money bag, by the player to control, can also move, when the money and money bag contact, to make extra points, and the money disappears, is such a simple idea

Main activity

Package Com.rp;import Android.app.activity;import Android.os.bundle;import android.view.window;import Android.view.windowmanager;public class Mainactivity extends Activity {@Overridepublic void OnCreate (Bundle Savedinstancestate) {super.oncreate (savedinstancestate);//Set Full screen This.getwindow (). SetFlags ( WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); Requestwindowfeature ( Window.feature_no_title);//Display Custom Surfaceview view Setcontentview (new Mysurfaceview (This));}}

Money This class

Package Com.rp;import Android.graphics.canvas;import Android.graphics.paint;import android.graphics.rect;public Class Money {//define coin private Rect money;public int moneyx=0,moneyy=0;//wallet coordinates public int speed=2;//The falling speed of the coin public int height; Private Boolean isdeath=false;private int cnt;//fractional public money (int moneyx,int speed,int height) {This.moneyx  = Moneyx;this.speed = Speed;this.height = height;this.cnt = speed;} public void Drawmoney (Canvas canvas,paint Paint) {money = new Rect (Moneyx, Moneyy, moneyx+10, moneyy+20); Canvas.drawrect ( Money, paint);} The logic of Money/*** * Free fall  When cross bounds when re-movement */public void logic () {if (Isdeath ()) {moneyy = 0;} Else{moneyy +=speed;}} /*** * Death function * When the money is over the bounds, or the money bag is met death */public Boolean Isdeath () {if (this.moneyy>=this.height) {Isdeath = true;} Else{isdeath = false;} return Isdeath;} public int getcnt () {return CNT;} public void setcnt (int cnt) {this.cnt = cnt;}}

A rocker system has been added here, no special effect, good-looking

Package Com.rp;import Android.graphics.canvas;import Android.graphics.paint;public class Yaogan {// Defines the center point coordinates of two circles with radius public float Smallcenterx = Smallcentery = 490, Smallcenterr = 20;public float Bigcenterx = +, bigcent ErY = 490, Bigcenterr = 40;public void Drawyaogan (Canvas canvas,paint paint) {//Draw great circle Canvas.drawcircle (Bigcenterx, Bigcentery, Bigcenterr, paint);//Draw Small Circle canvas.drawcircle (Smallcenterx, Smallcentery, Smallcenterr, paint);} /** * Small Circle for circular motion of the circle, set the coordinate position of the center point of the small circle * @param CenterX * Round (large circle) center point x Coordinate * @param centery * Around the circle (great circle) Center point y Coordinate * @param R * ROUND (circle) Radius * @param rad * rotational radian */public void setsmallcirclexy (float CenterX, float CenterY, float R, double rad) {//Get the x-coordinate of the circular motion Smallcenterx = (float) (R * Math.Cos (RAD)) + centerx;//get the y-coordinate of the circular motion Smallcent ErY = (float) (R * Math.sin (RAD)) + CenterY;} /** * Gets the radian between two points * @param px1 The X coordinate of the first point * @param py1 the Y coordinate of the first point @param px2 the X coordinate of the second point @param py2 the y-coordinate of the second point * @ret Urn */public double Getrad (fLoat px1, float py1, float px2, float py2) {//Get two points x distance float x = px2-px1;//get two points y distance float y = py1-py2;//calculate bevel length Float  hypotenuse = (float) math.sqrt (Math.pow (x, 2) + Math.pow (Y, 2));//Get the cosine of this angle (through the theorem in the trigonometric function: adjacent edge/hypotenuse = angle cosine) Float Cosangle = x  /hypotenuse;//obtains the radian of its angle by the inverse cosine theorem float rad = (float) math.acos (cosangle);//When the position of the touchscreen y-coordinate < The y-coordinate of the joystick we want to take the inverse value -0~-180 if (Py2 < PY1) {rad =-rad;} return rad;}}

The basic code has been given, there is no material, the code himself to test the success of the late has the possibility of planning to improve, of course, it is necessary to need a art to help
