Question by AlasdairHendry · May 10, 2017 at 06:26 PM · crashforeachfreezingnested

Nested Foreach Loop is freezing/crashing Unity.

Hi,

I am attempting to create a list of classes. These classes have categories. Each class within the same category can have a "Rival" of that same category.

I am using a nested foreach statement to find each class that is in my category and is not myself. The classes are rather large and have a lot of inheritence, so i don't know if Unity just can handle this much data, or i have some sort of error in my code that tunnel vision is blocking.

The Function that is crashing

 private void SetRivals()
     {
         foreach (Network network in Networks)
         {
             List<Network> matches = new List<Network>();
 
             foreach (Network target in Networks)
             {
                 if(target.Category == network.Category)
                 {
                     if(target != network)
                     {
                         matches.Add(target);
                     }
                 }
             }
 
             network.SetPossibleRivals(matches);
         }
     }

The Function being targetted

  public void SetPossibleRivals(List<Network> matches)
     {
         PossibleRivals.AddRange(matches);
     }

If needed, i can post the whole Class.

Thanks in advance!
