比賽規(guī)則
9球足球比賽是一項(xiàng)激烈的比賽，需要技巧、策略和團(tuán)隊(duì)合作。比賽在9名球員組成的兩支球隊(duì)之間進(jìn)行，比賽場地為一個(gè)小型的室內(nèi)球場。
游戲的目標(biāo)是進(jìn)球比對手多。比賽分為兩節(jié)，每節(jié)15分鐘。球可以用腳、頭或胸部踢，但不能用手或手臂。
球員位置
在9球足球比賽中，球員通常被分為以下位置：
-
守門員：守衛(wèi)球門并防止對手進(jìn)球。
-
后衛(wèi)：負(fù)責(zé)防守并組織進(jìn)攻。
-
中場：連接后衛(wèi)和前鋒，參與進(jìn)攻和防守。
-
前鋒：主要負(fù)責(zé)進(jìn)球。

使用以下控件控制球員和球：
<script>
const field = document.querySelector(".field");const ball = document.querySelector(".ball");const players = document.querySelectorAll(".player");const speed = 5;let player1Pos = { x: 20, y: 20 };let player2Pos = { x: 80, y: 20 };let player3Pos = { x: 140, y: 20 };let player4Pos = { x: 20, y: 80 };let player5Pos = { x: 80, y: 80 };let player6Pos = { x: 140, y: 80 };let player7Pos = { x: 20, y: 140 };let player8Pos = { x: 80, y: 140 };let player9Pos = { x: 140, y: 140 };let ballPos = { x: 100, y: 100 };const movePlayer = (player, direction) => {switch (direction) {case "up":player.y -= speed;break;case "down":player.y += speed;break;case "left":player.x -= speed;break;case "right":player.x += speed;break;}};const moveBall = (direction) => {switch (direction) {case "up":ball.y -= speed;break;case "down":ball.y += speed;break;case "left":ball.x -= speed;break;case "right":ball.x += speed;break;}};const kickBall = () => {const direction = prompt("請輸入踢球方向（上/下/左/右）：");moveBall(direction);};const updatePositions = () => {players.forEach((player) => {const playerPos = player.dataset.player;player.style.left = eval(playerPos + "Pos.x") + "px";player.style.top = eval(playerPos + "Pos.y") + "px";});ball.style.left = ballPos.x + "px";ball.style.top = ballPos.y + "px";};const handleControls = (e) => {switch (e.target.id) {case "move-up":movePlayer(player1Pos, "up");break;case "move-down":movePlayer(player1Pos,"down");break;case "move-left":movePlayer(player1Pos, "left");break;case "move-right":movePlayer(player1Pos, "right");break;case "kick":kickBall();break;}updatePositions();};const init = () => {document.addEventListener("keydown", handleControls);updatePositions();};init();
