JS贪吃蛇游戏,个人练习之用,放在这备份一下,
复制代码 代码如下:
<!DOCTYPE html>
<html xmlns="http://mon.height - 1));
isCover = false;
if (pos instanceof Array) {
for (var i = 0; i < pos.length; i++) {
if (x == pos[i].X && y == pos[i].Y) {
isCover = true;
break;
}
}
}
} while (isCover);
this.pos = new Position(x, y);
document.getElementById("box_" + x + "_" + y).className = "food";
};
}
function Position(x, y) {
this.X = 0;
this.Y = 0;
if (arguments.length >= 1) this.X = x;
if (arguments.length >= 2) this.Y = y;
}
</script>
