Easing
Easing functions specify the rate of change of a parameter over time. The website https://easings.net/ is a good resource to visualize common easing functions.
Objects in real life donβt just start and stop instantly, and almost never move at a constant speed. When we open a drawer, we first move it quickly, and slow it down as it comes out. Drop something on the floor, and it will first accelerate downwards, and then bounce back up after hitting the floor.
γ½οΈ Using easing functions
To specify which easing function a tween uses, the property ease can be set. This property is backed by a custom enum called Ease containing 30+ ease types.
tween.ease = Ease.QuadOut;
You can also use the easing functions directly through the static class EaseFunction.
Every easing function takes the form f(x):
public float EaseFunction(float x);
