How to change a float value with UI buttons,How Can I control a character with UI buttons?

Question

I want to change the value to -1 if the UI button is pressed and holded down and +1 if another button is pressed and holded down, then, in another script(character controller) i want to get the total of both( either -1, +1, or 0 if none(or both) of those 2 buttons are getting pressed). Thanks.

All this is for simulating a "GetAxisRaw" with two UI buttons, if you know how to do this in other way.,I'm trying to change the value of one float to -1 if one button is pressed and holded down, to 1 if another button is pressed and holded down and 0 if none of the buttons are getting pressed. The Main script to control the character is in the character, so I don't know how to interact between the two scripts

Let's say they are on the same gameObject. The first script is called Foo.cs and the second is called Bar.cs. To access the scripts if they are on the same object you can simply GetComponent<Foo>(); or GetComponent<Bar>();. If there's a value you are trying to get it could look like this:

 public class Bar: MonoBehaviour {
 
     void Start() {
         var foo_script = GetComponent<Foo>();
         float some_value = foo_script.some_value;
     }
 
 }

If they are on different gameObjects. Do the samething but from accessing that gameObject. If you have a tag on the gameObject called SomethingController you can do the same thing but with a minor adjustment:

 public class Bar: MonoBehaviour {
     
         void Start() {
             var foo_script = GameObject.FindWithTag("SomethingController").GetComponent<Foo>();
             float some_value = foo_script.some_value;
         }
     
     }
