Is there a way to manually change the Input.Axis values?

Question

I'm making a virtual controller, and I was wondering if I could manually change an Input.Axis's value. For example, when a game object is at a certain location, I want to be able to change the axis("horizontal") value to 1 or -1, without the help of hardware.

From what I've seen, I can only call GetAxis(name), but I'd like something like SetAxis(name, x). Is there any way to do this?

To answer my own question, it appears that you can not set custom values in the Input class. What I ended up doing was writing my own CustomInput class that allows for setting and getting input values.

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public static class CustomInput {
     static Dictionary<string,float> inputs = new Dictionary<string, float>();
     
     static public float GetAxis(string _axis){
         if(!inputs.ContainsKey(_axis)){
             inputs.Add(_axis, 0);
         }
         
         return inputs[_axis];
     }
     
     static public void SetAxis(string _axis, float _value){
         if(!inputs.ContainsKey(_axis)){
             inputs.Add(_axis, 0);
         }
         
         inputs[_axis] = _value;
     }
 }

All values are automatically added if they don't already exist. Use CustomInput.GetAxis(name) to get, and CustomInput.SetAxis(name, value) to set.

The only problem is, I'm not quite sure how optimized this will be for mobile, but feel free to use it anyways.

Another alternative - use CrossPlatformInput$$anonymous$$anager from Standart assets. See joystick script there as an example. To get values use: CrossPlatformInput$$anonymous$$anager.GetAxis(name) CrossPlatformInput$$anonymous$$anager.GetAxisRaw(name)

I have a certain use case wherein I could use your CustomInput class to get and set the axis value. The only caveat is that I'm using a library (Ros#) which uses Input.GetAxis(axisName) in some of their scripts. How would I expose the CustomInput to the Unity's own Input so that I could use this functionality without having to change much of the code in the library?

PS. I don't have much experience in Unity and I'm just beginning to learn concepts of Unity!

I've found another way - you can set input.GetAxis to a float and then change it's value.

private float horizontalInput;

void Update() { horizontalInput = Input.GetAxis("Horizontal");

 if (horizontalInput > 0) {// Move right}
 // Same as
 if (Input.GetAxis("Horizontal") > 0) { // Move right}}

That means you can change the horizontalInput if you want to but otherwise it will be equal to Input.GetAxis("Horizontal") - for example you can set it to a certain value if it meets a condition:

void Update() {

 if (!shouldMove) {
 horizontalInput = 0;

} else { horizontalInput = Input.GetAxis("Horizontal"); }

}

That's actually a really good solution that's so obvious that it's unintuitive.
