我一直在尝试使用 ncurses 库为 C++ 创建我的 roguelike 类型的游戏。在学习了许多不同的教程之后,我能够创建玩家角色、地图、防止玩家穿过墙壁的代码以及怪物角色的随机移动。
我遇到的下一个问题是实现一个布尔值,所以每当玩家角色与怪物角色交互时,游戏就会退出(很像 roguelike 游戏)。但是,我似乎无法让它以我想要的方式运行。我认为这与我为玩家和怪物设置的坐标有关,但我仍然不确定。谁能帮帮我?
这是代码:
#include <iostream>
#include <ncurses.h>
#define MAP_WIDTH 22
#define MAP_HEIGHT 15
#define TILE_FLOOR 0
#define TILE_WALL 1
int PlayerX, PlayerY;
void erase (int y, int x) {
mvaddch(y, x, '.');
}
