deki-tween

What it does

deki-tween animates any numeric property over time with a chosen easing curve. The module exposes two surfaces: a TweenComponent you configure in the inspector, and a TweenManager for programmatic control from C++.

Easing functions

30+ named easings, each in In, Out, and InOut variants where applicable:

• Linear
• Sine – SineIn, SineOut, SineInOut
• Quad / Cubic / Quart / Quint – standard polynomial families
• Expo – ExpoIn, ExpoOut, ExpoInOut
• Circ – CircIn, CircOut, CircInOut
• Back – overshoot at the end
• Elastic – spring oscillation
• Bounce – discrete-bounce decay

Example

Inspector-driven (drop a TweenComponent on an object, set fields):

auto* tween = obj->AddComponent<TweenComponent>();
tween->target_property = "x";
tween->from_value = 0.0f;
tween->to_value = 100.0f;
tween->duration = 1.0f;
tween->ease_type = EaseType::QuadOut;
tween->Play();

Code-driven, with a completion callback:

TweenManager::Get().TweenTo(
    &object->x,
    100.0f,
    1.0f,
    EaseType::BackOut,
    [](){ /* on complete */ }
);
