【问题描述】:
我目前正在创建一个游戏,一个平台游戏。我已经让角色水平移动了,但是,我真的不知道如何让他跳跃......同时移动。
我决定不使用 jQuery animate 来移动角色,因此我不知道如何让角色在跳跃的同时移动。我在JSFiddle 上看到了一个使用 jQuery 完美跳跃和移动的示例,但是它使用了animate。
我怎样才能让角色跳跃(平稳),和 可以在跳跃的同时移动(不使用动画)?
我有一个CodePen(Pen 中的 CSS 是 SCSS,但这里是 CSS),但无论如何这里是代码:
var game_anim = function() {
var level = [
[0, 1, "l", 1, 1, 1, 1, 0, 0, 0, 1, 1, 1, "l", "l", 1],
[0, 0, 0, 0, 2, 2, 2, 2, 2, 2],
[0, 0, 0, 0, 0, 3, 3, 0, 3],
];
var $player = $(".player");
var $game = $(".game");
$(document).keydown(function(event) { // keycodes: left = 37, right = 39
if (event.which == 39 || event.which == 68) { // right arrow or D
if ($player.position().left < $game.width() - $player.width()) {
$player.css("left", "+=10");
}
}
if (event.which == 37 || event.which == 81 || event.which == 65) { // left arrow or Q on AZERTY or A on QWERTY
if ($player.position().left > 0) {
$player.css("left", "-=10");
}
}
if (event.which == 38) {
if ($player.position().top > 0) {
$player.css("top", "-=10");
}
}
});
}
$(document).ready(function() {
game_anim();
});
