public class TankGame {
public static void main ( String [ ] args ) {
final int WINDOW_ WIDTH = 800;
final int WINDOW_ HEIGHT = 800;
final float PI = 3.1415926F;
int x = 0;
int y = 0;
int w = 0; int h = 50;
int speed = 10;
boolean isLive = true;
float firection = PI/4;
int bulletSpeed = speed * 2;
System. out. println ( " 坦克当前位置：x=" +x+" y=" +y );
System. out. println( " 坦克向右移动一帧" );
x=x+speed; //x变，y不变
System. out. println( " 坦克当前位置：x1=" +x+" y1=" +y );
System. out. println( " 坦克向下纵向运动一帧" );
y+=speed;
System. out. println( " 坦克当前位置：x2=" +x+" y2=" +y);
System. out. println( " 坦克斜向45度运动一帧" );
System. out. println( " 坦克当前位置：坦克当前位置：x3=" +x+" y3=" +y );
}
}
