Unity3d 游戏设计(一)井字棋
3D游戏设计(一)井字棋
运行效果:
实现过程
声明变量:
public Texture2D O;
public Texture2D X;
GUIStyle myStyle;
private int turn = 1;
/*记录谁的回合:turn=1为⚪,turn==2为×*/
int[][] board = new int[3][] { new int[3], new int[3], new int[3] };
reset()函数:用于重新开始游戏
/*重新开局*/
void reset() {
turn = 1;
for (int i = 0; i < 3; ++i) {
for (int j = 0; j < 3; ++j) {
board[i][j] = 0;
}
}
Debug.Log("game reset");
}
check()函数:检查游戏是否结束:未结束返回0,O胜利返回1,X胜利返回2,平局返回3。
/*检查胜利条件*/
int check() {
/*横线获胜*/
for (int i = 0; i < 3; i++) {
if (board[i][0] != 0 && board[i][0] == board[i][1] && board[i][1] == board[i][2]) {
return board[i][0];
}
}
/*纵线获胜*/
for (int i = 0; i < 3; i++) {
if (board[0][i] != 0 && board[0][i] == board[1][i] && board[1][i] == board[2][i]) {
return board[0][i];
}
}
/*斜线获胜*/
if (board[1][1] != 0 &&
board[0][0]== board[1][1] && board[2][2] == board[1][1] ||
board[0][2] == board[1][1] && board[2][0] == board[1][1]) {
return board[1][1];
}
/*对局还没结束*/
for (int i = 0; i < 3; ++i) {
for (int j = 0; j < 3; ++j) {
if (board[i][j] == 0) return 0;
}
}
/*平局*/
return 3;
}
display_result()函数:显示目前的游戏状态。
/*显示对局情况*/
void display_result(int res) {
int m = Screen.width / 2;
if (res == 0) {
if (turn == 1)
GUI.Box(new Rect(m - 50, 115, 100, 35), "O is going");
else
GUI.Box(new Rect(m - 50, 115, 100, 35), "X is going");
}
else if (res == 1) {
GUI.Box(new Rect(m - 50, 115, 100, 35), "O WIN");
}
else if (res == 2) {
GUI.Box(new Rect(m - 50, 115, 100, 35), "X WIN");
}
else if (res == 3) {
GUI.Box(new Rect(m - 50, 115, 100, 35), "Draw");
}
}
OnGUI()函数:实时渲染,采用预设的O、X图片来表示O、X已经下过的棋子。
void OnGUI() {
int m = Screen.width / 2;
GUI.Box(new Rect(m - 150, 80, 300, 420), "井字棋");
/*如果reset被点击则重开*/
if (GUI.Button(new Rect(m - 50, 160, 100, 35), new GUIContent("Reset", "点击重新开始"))) reset();
GUI.Label(new Rect(m - 150, 170, 150, 35), GUI.tooltip);
int res = check();
for (int i = 0; i < 3; ++i) {
for (int j = 0; j < 3; ++j) {
if (board[i][j] == 1) {
GUI.Button(new Rect(m - 150 + i * 100, 200 + j * 100, 100, 100), O);
}
else if (board[i][j] == 2) {
GUI.Button(new Rect(m - 150 + i * 100, 200 + j * 100, 100, 100), X);
}
if(GUI.Button(new Rect(m - 150 + i * 100, 200 + j * 100, 100, 100), "")) {
if (res == 0) {
if (turn == 1) {
board[i][j] = turn;
turn = 2;
}
else {
board[i][j] = turn;
turn = 1;
}
}
}
}
}
display_result(res);
}
可能存在的问题及解决方案:
可能存在井字棋显示不全的问题,此时把视野调至标准的1024*768即可。
可能存在预设对象未绑定的问题,此时把O对象绑定图片red_circle,把X对象绑定red_cha即可。
