foreach loop stops at first item

Question

hi! i have this is script and my foreach is not working properly, when i try to debug something inside it, it works perfectly, but if i put a if or for inside it, it only goes through it once

 public List<GameObject> allExercises = new List<GameObject>();
 public string[] exercisesSplitString;
 
 public void LoadData()
     {
           foreach(GameObject item in allExercises)
                 {
                     Debug.Log("hoo");
                     if(item.name == exercisesSplitString[0])
                     {
                         Debug.Log("heeey");
                     }
                 }

Some things to consider: - the first item name in allExercises IS the same as exercisesSplitString[0] - it doesn't debugs the 'heeey', only the 'hoo' and only once - if i erase the 'if', it debugs the 'hoo' correctly (which is 5 times) - obviously i'm not only trying to debug things, but i'm trying with debug to see if i can fix it before doing what i want to

thank you so much!

I have faced a similar problem. My solution was to simply use a coroutine instead. For example, in your case you could do:

 IEnumerator LoadData(){
          foreach(GameObject item in allExercises){
                      Debug.Log("hoo");
                      if(item.name == exercisesSplitString[0]){
                          Debug.Log("heeey");
                          yield return null;
                      }else{
                          //whatever you wanna do
                          yield return null;
                      }
           }
 }

And you could simply call this coroutine via:

 StartCoroutine(LoadData());

in whichever function you wish.

I don't think this is a solution to the problem, it only spreads the loop to do one item per frame instead of doing it all in one go.

foreach loop stops at first item
