Add "speed" to an object every X seconds

Questions & Answers
1

Hello everyone, my question is simple, I have this 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 this blocks) and I want that this 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 this start repeating. And the third one is how often it repeats.
For example:

public float movementSpeed = 10f;
 
 void increaseSpeed ()
    {
        movementSpeed = movementSpeed + 1f;
    }

  void Start()
    {
        InvokeRepeating("increaseSpeed", 5f, 10f); 
    }

What this 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

Sorry for asking this 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

@RonnieThePotatoDEV is there a way to do this with prefabs that are continuously spawning?

The problem I’m running into is that every new instance of a spawned prefab is set to its original object speed, but I’d like for each subsequent spawned prefab to move slightly faster than the previous, in the same way you showed above.

Appreciate any help here!
