Need help making temporary pick-ups (on-click) within game.

Hi guys, need help making a temporary pick-up within the game on mouse click on the UI

e.g. a pick-up called the Boots of Hermes lasts for 5 seconds after being picked up. The pick-up is placed in the game world and once picked up, the UI button for it changes and when clicked, it changes the players speed for 5 seconds then turns off. I've got the script for picking it up and awarding the player some score and then the UI button for it changes from greyed out to colored to indicate to the player it is picked up however the script for on click in the inspector I can't seem to get it working. It seems like it would change the speed but not change back after 5 seconds (using coroutines). I can post the codes i've been trying to use but can't for the life of me figure it out as I am not an expert haha. also, how do I do it when the pick-up is picked up,the player can only use it once.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class onClickHermes : MonoBehaviour
7. {
8.  
9.     public playerScript pScript;
10.  
11.  
12.     // Use this for initialization
13.     void Start()
14.     {
15.     }
16.  
17.  
18.  
19.  
20.     public void changeSpeed()
21.     {
22.         StartCoroutine(myTime()); //this is what is clicked on mouse click
23.      
24.      
25.     }
26.  
27.     IEnumerator myTime()
28.     {
29.         pScript.movementSpeed -= -15f;
30.         print("speedchange");
31.         yield return new WaitForSeconds(5f);
32.         pScript.movementSpeed += 10f;
33.         print("speeddefault");
34.      
35.      
36.    }
37. }

 

At the beginning of the coroutine, you add speed by subtracting a negative value, and at the end you add speed again.

 

hi Reeii thank you for the quick reply, what do you mean by this? You mean within my code itself or something that I need to do?

EDIT: I see you mean within the code, I saw it while researching but it works - just doesn't change after 5 seconds. Do you know how to fix?

 

nevermind now, Reeii you were right I fixed it. The values were in the wrong place thank you
