C + + game series 5: more than one weapon

Knowledge Point: An array of objects as a data member
Improvement: The weapons held by each character are not just one, so the weapons they hold are represented by an array of objects, and of course, they can be empty-handed.

As a result, it is also recorded that a common possession of a few weapons, currently armed with which weapons.

"Project-Role has a variety of weapons"
1.game.h: class declaration

2.point.cpp, defining the point class, representing the location

#include "game.h"#include <cmath>Point::P oint (intXintY): X (x), Y (y) {}intPoint::getx () {returnx;}intPoint::gety () {returnY;}//Move to a different pointvoidPoint::moveto (intXintY) { This->x=x; This->y=y;}//move from current positionvoidPoint::move (intDxintDY) { This->x+=dx; This->y+=dy;}DoublePoint::d istance (Constpoint& p) {DoubleDX = This->x-p.x;DoubleDY = This->y-p.y;return(sqrt (DX * dx + dy * dy));}

3.weapon.cpp, defining Weapon classes

#include "game.h"Weapon::Weapon(stringintdouble k):wname(wnam),force(f),killRange(k) {}Weapon::Weapon(const Weapon &w):wname(w.wname),force(w.force),killRange(w.killRange) {}string Weapon::getWname(){    return wname;}//返回杀伤力int Weapon::getForce(){    return force;}//返回杀伤距离double Weapon::getKillRange(){    return killRange;}

4.role.cpp, defines the role class. The role of participation in the game

5.main.cpp, test function, indicating position

#include <iostream>#include "game.h"Using namespaceSTD;int main () {Weapon w1[1]= {Weapon ("Gold stick", $, -)};//Golden CudgelWeapon w2[3]= {Weapon ("Fire-tip Lance", the, -),//Fire tip gun Weapon ("Universal Ring", -, -),//The Universe Circle Weapon ("Sky muddling Damask", -, +)//Mixed-day Aya};Role WuKong ("WuKong", -, Point (0,0), W1,1);Role Nezha ("Nezha", About, Point ( -, -), W2,3);WuKong.
