how to access a float from one script in other script in different objects

Questions & Answers

hi there, i have been digging for a while and tried multiple suggestions from similar questions but nothing is working, as you will understand i am very new to this and probably my problem is that i dont know exacly how to ask my issue. so here it goes:

i have a bunch of floats in various gameobjects and i want to have all that variable floats in one single component. so i created an empty object and named Controls and made a script to call for the floats.

i then call for a script from other object and tried to access the float from that script in this Controls script.

bellow the script i wanna call in Control:

public class PlayerMovement : MonoBehaviour

public float Jump;
public float Turn;

void Update() 
{
 if (Input.GetKey("space"))
    {
        Rb.AddRelativeForce(0, Jump * Time.deltaTime, 0, ForceMode.VelocityChange);          
    }

    if (Input.GetKey("e"))
    {
        transform.Rotate(0, Turn * Time.deltaTime, 0, (Space)ForceMode.VelocityChange);
    }

    if (Input.GetKey("q"))
    {
        transform.Rotate(0, -Turn * Time.deltaTime, 0, (Space)ForceMode.VelocityChange);
    }

}

Bellow the Universal Control Script

public class Controls : MonoBehaviour
{
public GameObject Player;
private PlayerMovement PM;

public float jump = 1000f;
public float turn = 200f;

public void Call()
{
    PM = Player.GetComponent<PlayerMovement>();
}
public void Control()
{
    PM.Jump = jump;
    PM.Turn = turn;
}

}
Clearly its not working as intended, but the idea would be to call multiple scripts and use all the variables as floats in this empty game object.

this would be only for development so i don’t care if its heavy its just for development faze then the variables would go to a settings menu or be fixed all together.

Thanks in advance i understand this might be straight forward but i didnt find the solution.

Why not just make it a constants:

public static class Constants
{
    public static class PlayerControls
    {
        public const float Jump = 1000f;
        public const float Turn = 200f;
    }
}

Then in your PlayerMovement class:

public class PlayerMovement : MonoBehaviour
{
    public float Jump = Constants.PlayerControls.Jump;
    public float Turn = Constants.PlayerControls.Turn;
}

You need to be careful, because modifying the jump/turn value of PlayerMovement in inspector, will overwrite constant value.
Better to then make the value either private, or use [HideInInspector] attribute to hide it.

You can also find an object in your scene and get the script component of that by using GameObject.Find("..."); where the ‘…’ is the name of the object in the scene

I don’t see why your script shoulnd’t work. You just have to call Call() in Controls start function.
