Jazz2::UI::Menu::AnimatedValue struct

#include <Jazz2/UI/Menu/Tweening.h>

Self-advancing animated scalar.

Lightweight 0–1 (or arbitrary range) value that eases toward a target at a fixed per-frame speed. Replaces the dozens of hand-rolled if (_a < 1.0f) _a += timeMult * k; and _a -= timeMult * k; counters previously duplicated across menu sections. Convert to the eased value implicitly, or read Raw for the linear value.

Constructors, destructors, conversion operators

AnimatedValue(float value = 0.0f, float target = 1.0f, float speed = 0.016f, Easing::Fn ease = Easing::Linear)

operator float() const

Implicitly converts to the eased value.

Public functions

void Update(float timeMult)

Advances the value toward the target.

auto Eased() const -> float

Returns the eased value.

auto Raw() const -> float

Returns the raw (un-eased) value.

auto IsDone() const -> bool

Returns true if the value reached its target.

void Restart(float from = 0.0f, float to = 1.0f)

Restarts the animation from the specified value toward 1.0f.

Public variables

float Value

Current raw (un-eased) progress.

float Target

Target the value advances toward.

float Speed

Amount the raw value changes per timeMult unit.

Easing::Fn Ease

Easing function applied when reading the value.
