Easing Effects

Easing is an animation technique that adds acceleration and deceleration to objects you want to move.

There are four types of Easing animations: Linear, Ease In, Ease Out, Ease In/Out.

While there are seven types of Varied Tweens: Quadratic, Quartic, Cubic, Sinusoidal (Sine), Qintic, Exponential and Circula.

Linear

Linear means that the object will animate in equal amounts of value/velocity and time.

Linear

There is no acceleration or deceleration

Ease In

Ease In means the object will start from zero value/velocity and then speeds up.

Accelerating from zero value

Ease Out

Ease Out means the object will start fast and then slows down to a stop.

Decelerating to zero value

Ease In/Out

Ease In/Out is half-half of the motion of Ease In and Ease Out. A visual example of Ease In/Out movement is an Elevator.

Accelerating until halfway

where it decelerates.

Varied Tweens

Varied Tweens are just different ways to do the easing motions based on a certain equation.

What's listed here is nothing more than a quick summary of the tweens. If you would like a more in-depth explanation, we will provide the links below.

Quadratic Easing - Also known as 'normal' easing, the motion is based on a square variable (t2).

Cubic Easing - The motion is based on the power of three (t3) and as a result, has a curved motion.

Quartic Easing - The motion is based on the power of four (t4) and as a result, applies a bend in the curved motion.
This causes the acceleration to be more exaggerated.
Quintic Easing - The motion is based on the power of five(t5) this causes the motion curve to be more pronounced. It starts quite slow then becomes quite fast.

Sinusoidal (Sine) Easing - The equation is based on a sine or cosine (p(t) = sin(t × π/2) which both results to a sine wave motion.
Exponential Easing - The motion is something that resembles a slope. You have precise control over the duration of the tween, and can jump to any point in time without running the tween from the starting point.
Circula Easing - This is based on the equation for half of a circle, which uses a square root. Similar to Quintic and Exponential, the acceleration for circular easing is dramatic and sudden than the others.
