????????一個(gè)純純小白，想寫點(diǎn)什么，也想學(xué)習(xí)一下怎么在這里寫東西，就簡(jiǎn)單的寫個(gè)2048小游戲。寫的不好，大佬就不用看了，希望和大家交流學(xué)習(xí)，有寫的不好或有更好的建議也歡迎提出來(lái)。（需要用的可直接粘貼復(fù)制）（輕噴）

游戲展示
????????基本上做到了和手機(jī)上一樣。 我會(huì)按照我的思路為大家講解一下，有需要的可以看看，想直接看效果或者需要用的，可以直接滑倒最后粘貼復(fù)制。
講解?
目錄結(jié)構(gòu)如下
?按照我自己的思路講一下，可能有點(diǎn)亂。
? ? ? ? 1.首先初始化一下畫板，將不會(huì)改變的部分先完成。
private void initPaint(Graphics g) {
//TODO 畫方塊所造區(qū)域
g.setColor(new Color(192, 175, 159));
g.fillRect(10, 120, 360 + 8, 360 + 8);
//TODO 畫得分區(qū)域以及說(shuō)明區(qū)域
g.setColor(new Color(209, 132, 102));
g.fillRect(200, 15, 80, 50);
g.fillRect(290, 15, 80, 50);
g.setColor(Color.black);
g.setFont(new Font("宋體", Font.BOLD, 20));
g.drawString("得分", 220, 35);
g.drawString("最高分", 300, 35);
g.setFont(new Font("宋體", Font.BOLD, 35));
g.drawString("游戲說(shuō)明：", 15, 55);
g.setFont(new Font("宋體", Font.BOLD, 20));
g.drawString("按上下左右鍵控制;按空格鍵重新游戲", 15, 100);
//畫空白方塊
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
paintBlock(g, new Block(table[i][j]), j, i);
}
}
}? ? ? ? ?2.創(chuàng)建帶有數(shù)字的方塊，這里創(chuàng)建了一個(gè)block類，主要存儲(chǔ)了，每種方塊所顯示的數(shù)字，數(shù)字顏色，背景顏色等屬性。并且有一個(gè)setAllFont方法，來(lái)設(shè)置這些屬性。
package game_2048;
import java.awt.*;
public class Block {
int kind;
Font wFont;
Color wColor;
Color bColor;
String s;
public Block(int kind) {
this.kind = kind;
}
private final Font font1 = new Font("宋體", Font.BOLD, 46);
private final Font font2 = new Font("宋體", Font.BOLD, 40);
private final Font font3 = new Font("宋體", Font.BOLD, 34);
private final Font font4 = new Font("宋體", Font.BOLD, 28);
private final Color color1 = new Color(119,108,99);
private final Color color2 = new Color(254,254,254);
public void setAllFont() {
switch (kind) {
case 0 -> bColor = new Color(206, 194, 180);
case 1 -> {
wFont = font1;
wColor = color1;
bColor = new Color(237, 229, 218);
s = 2 + "";
}
case 2 -> {
wFont = font1;
wColor = color1;
bColor = new Color(237, 220, 190);
s = 4 + "";
}
case 3 -> {
wFont = font1;
wColor = color1;
bColor = new Color(242, 177, 123);
s = 8 + "";
}
case 4 -> {
wFont = font2;
wColor = color2;
bColor = new Color(246, 147, 92);
s = 16 + "";
}
case 5 -> {
wFont = font2;
wColor = color2;
bColor = new Color(245, 118, 86);
s = 32 + "";
}
case 6 -> {
wFont = font2;
wColor = color2;
bColor = new Color(245, 83, 45);
s = 64 + "";
}
case 7 -> {
wFont = font3;
wColor = color2;
bColor = new Color(237, 206, 115);
s = 128 + "";
}
case 8 -> {
wFont = font3;
wColor = color2;
bColor = new Color(230,209,81);
s = 256 + "";
}
case 9 -> {
wFont = font3;
wColor = color2;
bColor = new Color(207,163,12);
s = 512 + "";
}
case 10 -> {
wFont = font4;
wColor = color2;
bColor = new Color(229,180,6);
s = 1024 + "";
}
case 11 -> {
wFont = font4;
wColor = color2;
bColor = new Color(161,131,115);
s = 2048 + "";
}
default -> {
}
}
}
}
? ? ? ? 3.繪制每個(gè)方塊（這里在1里面已經(jīng)用過(guò)了，當(dāng)時(shí)是畫空白的）
//畫方塊
private void paintBlock(Graphics g, Block block, int x, int y) {
block.setAllFont();
g.setColor(block.bColor);
g.fillRect(10 + x * 90 + 7, 120 + y * 90 + 7, 83, 83);
if (block.kind > 0) {
g.setColor(block.wColor);
g.setFont(block.wFont);
FontMetrics fm = getFontMetrics(block.wFont);
String value = block.s;
g.drawString(value,
10 + x * 90 + 7 + (83 - fm.stringWidth(value)) / 2,
120 + y * 90 + 7 + (83 - fm.getAscent() - fm.getDescent()) / 2 + fm.getAscent());
}
}
? ? ? ? ?4.初始化界面，包括分?jǐn)?shù)，和最開(kāi)始顯示的方塊。
? ? ? ? 用random類來(lái)隨機(jī)刷新方塊存在的位置。
? ? ? ? 這里的getS()和后面的setS()分別是讀、取文件，為了顯示最高分用。（這兩個(gè)方法寫了不是很好，就不講了）
private void init() {
isOver = false;
source = 0;
try {
best = getS();
} catch (IOException e) {
throw new RuntimeException(e);
}
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
table[i][j] = 0;
}
}
bX = rand1.nextInt(4);
bY = rand2.nextInt(4);
table[bX][bY] = 1;
}? ? ? ? 5.?控制所有方塊的移動(dòng)。
? ? ? ? 通過(guò)一系列控制語(yǔ)句，來(lái)決定是否能移動(dòng)或者合并。我這里是為了做滑動(dòng)的效果，可能寫的有點(diǎn)啰嗦，反正能用就行吧。
private void bDown() {
for (int j = 0; j <= 3; j++) {
//第一個(gè)if是為了一種稍微特殊的地方
//后面的每個(gè)方向都一樣
if (table[0][j] == table[1][j] && table[2][j] == table[3][j]
&& table[0][j] != 0 && table[2][j] != 0) {
table[1][j]++;
table[0][j] = 0;
}
for (int i = 2; i >= 0; i--) {
if (table[i + 1][j] == 0) {
table[i + 1][j] = table[i][j];
table[i][j] = 0;
}
if (table[i][j] != 0 && table[i][j] == table[i + 1][j]) {
if (c[j]) {
table[i + 1][j]++;
table[i][j] = 0;
c[j] = false;
source += (int) Math.pow(2, table[i + 1][j]);
}
}
}
}
}? ? ? ? 6.我這里是用線程的方法，來(lái)實(shí)現(xiàn)滑動(dòng)的效果。
? ? ? ? 每次按按鍵后，將改變fx的值，然后啟動(dòng)線程，每次會(huì)執(zhí)行三次方塊的移動(dòng)，每次延遲40ms，依次來(lái)達(dá)到滑動(dòng)的效果。
@Override
public void run() {
for (int i = 0; i < 4; i++) {
c[i] = true;
}
int[][] tt = new int[4][4];
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
tt[i][j] = table[i][j];
}
}
for (int k = 0; k < 3; k++) {
switch (fx) {
case 0 -> bUp();
case 1 -> bRight();
case 2 -> bDown();
case 3 -> bLeft();
default -> {
}
}
try {
Thread.sleep(40);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
if (best < source) {
best = source;
try {
setS(source);
} catch (IOException ioException) {
ioException.printStackTrace();
}
}
repaint();
}
isMove = false;
loop:
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
if (tt[i][j] != table[i][j]) {
isMove = true;
break loop;
}
}
}
randomBlock();
}? ? ? ? 8.隨機(jī)生成新的方塊。?每次移動(dòng)之后，就會(huì)隨機(jī)產(chǎn)生新的方塊，并且也在這里設(shè)置了結(jié)束的條件。
private void randomBlock() {
v.clear();
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
if (table[i][j] == 0) {
v.add(i);
v.add(j);
}
}
}
if (v.size() > 0 && isMove) {
int kk = rand.nextInt(v.size() / 2);
table[v.get(kk * 2)][v.get(kk * 2 + 1)] = (rand.nextInt(7) % 6 == 0) ? 2 : 1;
}
if (v.size() == 0) {
boolean isSame = false;
loop1:
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 4; j++) {
if ((table[i][j] == table[i + 1][j]) || (table[j][i] == table[j][i + 1])) {
isSame = true;
break loop1;
}
}
}
if (!isSame) {
isOver = true;
repaint();
}
}
}就這樣吧，，，有啥問(wèn)題也可以問(wèn)，我也會(huì)回答。。。。。。
代碼
best.txt
? ? ? ? best.txt主要用來(lái)記錄最高得分，創(chuàng)建時(shí)候需要在里面存儲(chǔ)個(gè)0，不然讀取的時(shí)候會(huì)報(bào)錯(cuò)。
