跳入 Godot 感觉很糟糕，但代码似乎还可以 [关闭]

问：

跳跃是如此突然和紧张。 我想这可能是因为我将游戏的分辨率设置为 1980x1080，但谁知道呢。 当我想改变角色时，脚本还会切换动画。我不认为这是最好的方法，但它有效，但正因为如此，我不得不禁用插值。我不知道为什么。 代码如下：

        _AnimationPlayer = GetNode<AnimationPlayer>("AnimationPlayer");
        slowedTimer.Start();
    }

我想要一个平稳的跳跃，感觉不错。此外，此代码还包括玩家放慢速度的部分，因为我希望水滴在我的游戏中移动。
