How to set transition from one animation to another unity?

Question

C++ / C#

The character has 2 animations, a state of rest and a state of running, how to make them switch between each other? or rather, you need a script to switch

Answer 1

There are three excellent tutorials for creating animations:
Fundamentals of creating a 2D character in Unity 3D 4.3. Part 1: character preparation and rest animation

The version of Unity is old, and some things will have to be changed in the code - first of all, add
a reference variable to the rigidbody and initialize it in Start ():

private new Rigidbody2D rigidbody2D;
void Start()
{
    rigidbody2D = GetComponent<Rigidbody2D>();
}
