Please tell me how to correctly implement the life bar in the UI, namely:
1. movement of the red bar to show the fullness of the heart.
2. Digital value display of life in the form of numbers.

How are you recording "life"? As a Global variable?

Variable values can be displayed in Label elements via text tokens - see this tutorial.

For your red bar, custom scripting would be necessary - since you'd be looking to control the size of the Image's RectTransform based on the variable's value.

First though, you'll need to set its RectTransform's Pivot X value to 0, so that changing its Scale X property is all you need - no need to also affect the position.

What is the maximum "life" value, and what is the maximum "Scale X" value on the RectTransform (i.e. the scale X when fully red)?

Made according to the lesson looks good.

Did as you said.

Regarding the maximum value, there is a difficult answer. Since the parameter life in the game is not an unambiguous parameter. This means that the player will have 100 life units and when the value is 0 he will die. But in the game I plan to implement the "Equipment" system, which means that if the player put on a T-shirt, then +2 units were added to the life parameter, if he put on a bulletproof vest, then +25 was added. And at the same time, the text value can reach 125 units, since it is a text and a number, but with a strip, the value here should remain no more than 100 (a red-foamed heart), since a red strip will appear in RectTranform. At the moment, I have 0 = 0 life from the length of the strip, and 100 units of life in RectTranform for X is 1.5.

Can you please tell me how to implement this mechanism?

Create a separate variable named MaxLife to represent the maximum health the player can have - with a default value of 100.

Then attach this script to your life icon:

using UnityEngine;
using AC;

public class LifeIcon : MonoBehaviour
{

    void Update ()
    {
        int life = GlobalVariables.GetVariable ("Life").IntegerValue;
        int maxLife = GlobalVariables.GetVariable ("MaxLife").IntegerValue;
        float lifeProportion = (float) life / (float) maxLife;
        Vector3 scale = GetComponent<RectTransform> ().localScale;
        scale.x = lifeProportion;
        GetComponent<RectTransform> ().localScale = scale;
    }
}

using UnityEngine;
using AC;

public class LifeIcon : MonoBehaviour
{
     int life;
     int maxLife ;
     float lifeProportion ;
     Vector3 scale;
     RectTransform _rect;

    void Start()
    {
       _rect = GetComponent<RectTransform> ();
    }

    void Update ()
    {
        life = GlobalVariables.GetVariable ("Life").IntegerValue;
        maxLife = GlobalVariables.GetVariable ("MaxLife").IntegerValue;
        lifeProportion = (float) life / (float) maxLife;
        scale = _rect.localScale;
        scale.x = lifeProportion;
        _rect.localScale = scale;
    }
} `

It works, but how do they organize the logic so that damage is done?
Or was life added from getting food?

A variable's value can be updated with the Variable: Set Action.
