#include <Magnum/Ui/TextLayerAnimator.h>

Text layer style animator.

Each animation is a transition between two TextLayer styles, with individual properties interpolated with an easing function. BaseLayerStyleAnimator is a matching animator for the BaseLayer.

Setting up an animator instance

The animator doesn't have any shared state or configuration, so it's just about constructing it from a fresh AbstractUserInterface::createAnimator() handle and passing it to setStyleAnimatorInstance().

Ui::TextLayerStyleAnimator& animator = ui.setStyleAnimatorInstance(
    Containers::pointer<Ui::TextLayerStyleAnimator>(ui.createAnimator()));

After that, the animator has to be registered with a concrete layer instance. The animations make use of dynamic styles, so the text layer is expected to have at least one dynamic style enabled with TextLayer::Shared::Configuration::setDynamicStyleCount(). The more dynamic styles are enabled, the more style animations can be running for given layer at the same time, but also more data need to get uploaded to the GPU every frame. Finally, call TextLayer::assignAnimator(TextLayerStyleAnimator&) to assign the animator to the layer instance. Then, assuming AbstractUserInterface::advanceAnimations() is called in an appropriate place, the animator is ready to use.

Ui::TextLayerGL::Shared textLayerShared{
    Ui::TextLayer::Shared::Configuration{…}
        …
        .setDynamicStyleCount(10) /* adjust as needed */
};
Ui::TextLayer& textLayer = ui.setLayerInstance(
    Containers::pointer<Ui::TextLayerGL>(ui.createLayer(), textLayerShared));

…

textLayer.assignAnimator(animator);

Unlike builtin layers or layouters, the default UserInterface implementation doesn't implicitly provide a TextLayerStyleAnimator instance.

Creating animations

Assuming an enum is used to index the styles defined in TextLayer::Shared of the associated layer instance, an animation is created by calling create() with the source and target style indices, an easing function from Animation::Easing or a custom one, time at which it's meant to be played, its duration, and a DataHandle which the style animation should affect. Here, for example, to fade out a button hover style over half a second:

enum class TextLayerStyle {
    …
    Button,
    ButtonHover,
    …
};

Ui::DataHandle buttonText = …;

animator.create(TextLayerStyle::ButtonHover, TextLayerStyle::Button,
    Animation::Easing::cubicOut, now, 0.5_sec, buttonText);

Internally, once the animation starts playing, the animator allocates a new dynamic style index using TextLayer::allocateDynamicStyle() and switches the style index of given DataHandle to the allocated dynamic style with BaseLayer::setStyle(). During the animation the style data are updated to corresponding interpolation between the source and target styles, equivalent to calling TextLayer::setDynamicStyle(). When the animation stops, the data style index is switched to the target ID specified in create() and the dynamic style index is recycled with TextLayer::recycleDynamicStyle() is called for the dynamic style.

If the animator runs out of dynamic styles, newly played animations are left at the source style index until another dynamic style is recycled. If no dynamic style gets recycled until the animation ends, the data gets switched directly to the target style without animating.

The animation interpolates all properties of TextLayerStyleUniform as well as the style padding value. The font, alignment or text feature style properties cannot be animated and thus are set to properties of source style at the beginning. If the styles reference a cursor or editing style, the corresponding TextLayerEditingStyleUniform including its padding value, and the selection TextLayerStyleUniform override is animated as well.

At the moment, only animation between predefined styles is possible.

Animation lifetime and data attachment

As with all other animations, they're implicitly removed once they're played. Pass AnimationFlag::KeepOncePlayed to create() or addFlags() to disable this behavior.

Style animations are associated with data they animate, and thus as soon as the data or node the data is attached to is removed, the animation gets removed as well. If you want to preserve the animation when the data is removed, call attach(AnimationHandle, DataHandle) with DataHandle::Null to detach it from the data before removing.

If you call create() with DataHandle::Null, the animation will still allocate and interpolate a dynamic style, but the style won't be used anywhere. You can then retrieve the dynamic style index with dynamicStyle() and use it for example to make the same style animation on multiple different data. Note that in this case you're also responsible also for switching to the target style once the animation finishes — once the dynamic style is recycled, the same index may get used for arbitrary other style either by this animator or any other code, causing visual bugs.

Function documentation

Magnum::Ui::TextLayerStyleAnimator::TextLayerStyleAnimator(AnimatorHandle handle) explicit

Constructor.

Parameters
handle Handle returned by AbstractUserInterface::createAnimator()

Magnum::Ui::TextLayerStyleAnimator::TextLayerStyleAnimator(TextLayerStyleAnimator&&) noexcept

Move constructor.

Performs a destructive move, i.e. the original object isn't usable afterwards anymore.

AnimationHandle Magnum::Ui::TextLayerStyleAnimator::create(UnsignedInt sourceStyle, UnsignedInt targetStyle, Float(*)(Float) easing, Nanoseconds played, Nanoseconds duration, DataHandle data, UnsignedInt repeatCount = 1, AnimationFlags flags = {})

Create an animation.

Parameters
sourceStyle Style index to animate from
targetStyle Style index to animate to
easing Easing function between 0.0f and 1.0f, used for all style uniform values as well as the padding. Pick one from Animation::Easing or supply a custom one.
played Time at which the animation is played. Use Nanoseconds::max() for creating a stopped animation.
duration Duration of a single play of the animation
data Data the animation is attached to. Use DataHandle::Null to create an animation that isn't attached to any data.
repeatCount Repeat count. Use 0 for an indefinitely repeating animation.
flags Flags

Expects that TextLayer::assignAnimator(TextLayerStyleAnimator&) has been already called for this animator, that both sourceStyle and targetStyle are less than TextLayer::Shared::styleCount() (not TextLayer::Shared::totalStyleCount() — the style animation is not allowed to use the dynamic style indices) and that easing is not nullptr.

Delegates to AbstractAnimator::create(Nanoseconds, Nanoseconds, DataHandle, UnsignedInt, AnimationFlags), see its documentation for more information.

The animation affects the TextLayerStyleUniform and the padding value, if it differs between the styles. The animated dynamic style is initialized from font, alignment and features from styleSrc, if styleDst has them different, they don't affect the animation in any way. If given style references a cursor or editing style, it affects also the corresponding TextLayerEditingStyleUniform, the editing padding value, if it differs between the editing styles, and the TextLayerStyleUniform override for selected portions of the text, if referenced.

Returns Style properties that were affected by the animation

Used internally from TextLayer::advanceAnimations(Nanoseconds, Containers::MutableBitArrayView, const Containers::StridedArrayView1D<Float>&, Containers::MutableBitArrayView, const Containers::Iterable<AbstractStyleAnimator>&), which is called from AbstractUserInterface::advanceAnimations(). Exposed just for testing purposes, there should be no need to call this function directly and doing so may cause internal AbstractUserInterface state update to misbehave.

Expects that size of active, factors and remove matches capacity(), it's assumed that their contents were filled by update() before. Assuming the layer the animator is associated with doesn't contain editing styles, the dynamicStyleUniforms, dynamicStyleCursorStyles, dynamicStyleSelectionStyles and dynamicStylePaddings, are expected to all have the same size and should be large enough to contain any valid dynamic style ID, the dynamicEditingStyleUniforms and dynamicEditingStylePaddings views are then expected to be empty. Assuming the layer contains editing styles, the dynamicStyleUniforms is expected to be three times as large as the others, and the dynamicEditingStyleUniforms and dynamicEditingStylePaddings views twice as large as the others instead. The dataStyles view should be large enough to contain any valid layer data ID.
