Changes animations quickly will stall the animation

[FastestMolasses]

Typically, spritesheets will have rows that represent different directions of the same sprite with the same animation. With this library, each direction of the sprite's animation would be in a new animation clip. As a result, when switching between the directions of the animation, despite being the same animation type, the animation will stall and not progress.

The issue stems from setting the accumulated_time of the AnimationInstance back to zero when the animation changes. A proposed change will be to group the different directions of an animation to be able to determine whether to reset the accumulated_time or to leave it be.

Hi @FastestMolasses,

I'm guessing that you used the SpritesheetAnimation::switch() method for switching between animations.
Is that correct?

Does setting the animation_id of the SpritesheetAnimation component without calling switch() solve your issue?

From the source code:

/// Switches to a different animation.
///
/// # Note
///
/// To change the animation while keeping the current `frame` and `repetition` indices, directly set `animation_id` instead.
pub fn switch(&mut self, animation_id: AnimationId) {
    ...
}

No I don't utilize switch in my code. I am setting the animation id directly and manually calling .reset when the sprite sheet itself changes. When I'm only changing the row, that's when Im setting the animation id manually:

sprite_sheet.animation_id = anim;
    if sprite.image != new_sprite.image {
        *sprite = new_sprite.clone();
        sprite_sheet.reset();
    }

The issue comes when changing rows of the sprite sheet, the accumulated_time gets reset back to zero and makes it so that the animation doesn't continue to the next frame. This is desirable for most scenarios but not for scenarios where you want to maintain the animation playing but only change the direction (the row of the sprite sheet).

Edit: For clarification, when I say "changing rows" I mean changing the direction a sprite is facing. Each row of my sprite sheets is of the same sprite and animation, but for different possible directions.
