Add "speed" to an object every X seconds

Question

Hello everyone, my question is simple, I have t$$anonymous$$s script that moves blocks at a certain speed and destroys them as you can see in the script (and I have other script that spawns t$$anonymous$$s blocks) and I want that t$$anonymous$$s variable:

 public float movementSpeed = 10f;

to be more every X seconds, for example, every 10 seconds add 1 to the variable, so the speed of the objects is 11, and every other 10 seconds add another 1 to the variable so it is 12, and so on, but if I add a Coroutine and new objects are spawned they always have 10 in the variable, I want it to be like a "universal" variable so the new objects spawned have the "new" speed... I have no idea how to do it maybe it's very simple but if anyone could help me it would be appreciated. thanks and sorry for bad english, here's the script:

 using UnityEngine;
  using System.Collections;
  
  public class Block : MonoBehaviour {
  
      public float movementSpeed = 10f;
  
      void Start ()
      {
  
      }
  
      // Update is called once per frame
      void Update () {
  
          transform.Translate(Vector3.down * movementSpeed * Time.deltaTime);
  
          if (transform.position.y < -2f)
          {
              Destroy(gameObject);
          }
      }
  }

Use InvokeRepeating. It just lets you repeat a function over and over again. It has three parameters. The first is the function it is repeating (in your case it will be a function that will be increasing the variable), the second one is after how many seconds will t$$anonymous$$s start repeating. And the t$$anonymous$$rd one is how often it repeats. For example:

 public float movementSpeed = 10f;
  
  void increaseSpeed ()
     {
         movementSpeed = movementSpeed + 1f;
     }
 
   void Start()
     {
         InvokeRepeating("increaseSpeed", 5f, 10f); 
     }

What t$$anonymous$$s does it that it first makes a function, "increaseSpeed", and then when the game starts it waits five seconds, then it repeats that function every ten seconds

T$$anonymous$$s will help more: https://docs.unity3d.com/ScriptReference/MonoBehaviour.InvokeRepeating.html

Hope it helps -Ronnie

Sorry for asking t$$anonymous$$s question after so long. The code you gave worked for me as well, but is there a way to cap the speed? Thanks so much! @RonnieThePotatoDEV

If you mean by making the speed increase stop after it reaches a certain point then just add a if statement

 public float movementSpeed = 10f;
 
 void increaseSpeed ()
 {
     movementSpeed = movementSpeed + 1f;
 }
 
 void Start()
 {
     InvokeRepeating("increaseSpeed", 5f, 10f); 
 }
 
 void Update()
 {
     if (movementSpeed >= 50f)
     {
         CancelInvoke("increaseSpeed");
     }
 }

again I don't know if this is the best way, but it gets the job done

Add "speed" to an object every X seconds
