How to change the colors of a ColorMaterialColorLens of an existing tween in a system

[tvdboom]

Hi,

I have a tween spawned like this to animate the alpha of a mesh. This works.

let material =
    materials.add(ColorMaterial::from(OWN_COLOR_DEFAULT.with_alpha(0.)));
parent.spawn((
    Mesh2d(
        meshes.add(Annulus::new(planet.size() * 0.55, planet.size() * 0.57)),
    ),
    MeshMaterial2d(material.clone()),
    Transform::from_xyz(0., 0., 0.6),
    TweenAnim::new(
        Tween::new(
            EaseFunction::SineInOut,
            Duration::from_secs(2),
            ColorMaterialColorLens {
                start: OWN_COLOR_DEFAULT.with_alpha(0.),
                end: OWN_COLOR_DEFAULT.with_alpha(1.),
            },
        )
        .with_repeat_count(RepeatCount::Infinite)
        .with_repeat_strategy(RepeatStrategy::MirroredRepeat),
    ),
    AnimTarget::asset(&material),
    Visibility::Hidden,
    PlanetaryShieldCmp,
));

However, I want to change the color of the annulus when the player hovers over something. I have this code in a system:

if let Ok((mut visibility, mut tween)) = ps_q.get_mut(child) {
    *visibility = if has_ps {
        let color = if selected {
            OWN_COLOR_HOVER
        } else {
            OWN_COLOR_DEFAULT
        };
        *tween = TweenAnim::new(
            Tween::new(
                EaseFunction::SineInOut,
                Duration::from_secs(2),
                ColorMaterialColorLens {
                    start: color.with_alpha(0.),
                    end: color.with_alpha(1.),
                },
            )
            .with_repeat_count(RepeatCount::Infinite)
            .with_repeat_strategy(RepeatStrategy::MirroredRepeat),
        );
        Visibility::Inherited
    } else {
        Visibility::Hidden
    }
}

but then nothing shows.

I also tried this

if let Ok((mut visibility, tween)) = ps_q.get_mut(child) {
    *visibility = if has_ps {
        if let Some(material) = materials.get_mut(&*ps_m) {
            material.color = if selected {
                OWN_COLOR_HOVER.with_alpha(0.)
            } else {
                OWN_COLOR_DEFAULT.with_alpha(0.)
            };
        }
        Visibility::Inherited
    } else {
        Visibility::Hidden
    }
}

which works when I remove the animation, but doesn't work with the tween.

How can I make the color of the twee change? Thanks
