QuickTween is a lightweight, fast, and flexible tweening framework for Unreal Engine, designed to make value interpolation smooth and easy to use in both C++ and Blueprints.
Tweening, short for “in-betweening,” is the process of smoothly transitioning a value over time.
Instead of instantly jumping from one state to another, tweening calculates gradual steps in between, creating fluid motion or progression.
Tweening can be applied to many things:
Moving an actor from one location to another
Fading UI elements in or out
Changing colors, scales, or rotations
Animating camera transitions
Adjusting gameplay variables over time
Rather than manually updating values every frame, a tweening system handles the timing, interpolation, easing, and completion events for you.
Why is Tweening Useful?
Tweening allows developers to achieve polished motion and feedback with minimal effort.
Its benefits include:
Smoother and more natural animations
Reduced boilerplate code for time-based changes
Easy control over timing and easing styles
Cleaner logic that separates animation behaviour from game logic
Faster iteration when experimenting with motion or transitions
Whether used for subtle UI animations or dynamic gameplay sequences, tweening helps make interactions feel responsive, polished, and engaging.
This is where QuickTween comes in: providing an easy and flexible way to apply tweening inside Unreal Engine, both in C++ and Blueprints.
