Check Player Quantities

Player Resources and Required Resources follow a similar pattern;

Code (CSharp):

1. public struct RequiredResources
2. {
3.     public Resource resource;
4.     public int quantityRequired;
5. }

Code (CSharp):

1. public class Resource : ScriptableObject
2. {
3.     [SerializeField]
4.     private string resourceName;
5.     public string GetName() { return resourceName; }
6.  
7.     [SerializeField]
8.     public Sprite icon;
9.     public Sprite GetIcon() { return icon; }
10. }
11.  

The resources available to the player are as follows;
Food, Gold, Wood, Stone

I wish to use a system like this so I can easily add more resources as needed. When a building is placed it has a list of resources required to build it, for example a house may cost;
Gold = 5
Wood = 3

With the code below this will loop through the resources and reduce the amount as required. Basically the amount the player has - the cost, then update the UI.

Code (CSharp):

1. public void UseResources()
2.     {
3.         foreach (RequiredResources requiredResources in building.GetResources())
4.         {
5.             foreach (ResourceManager.PlayersResources resource in player.playersResources)
6.             {
7.                 if (requiredResources.resource.Equals(resource.GetResourceType()))
8.                 {
9.                     resource.RemoveQuantity(requiredResources.quantityRequired);
10.                 }
11.             }
12.         }
13.     }

However, before running this I want to check if the player even has enough resources. When I use a similar logic to return true and false, and the player has enough wood (true) but not enough gold (false), it will remove the amount for both. I am at such a loss as to a way to do this correctly.

Please help!

 

Code (CSharp):

1.     public bool HasRequiredResources(RequiredResources[] requiredResources)
2.     {
3.         foreach (RequiredResources r in requiredResources) //go through all required resources
4.         {
5.             foreach (PlayersResources p in playersResources)
6.             {
7.                 if (r.quantityRequired > p.GetCurrAmount())
8.                     Debug.Log("Has enough " + r.resource.name);
9.                     return false;
10.             }
11.         }
12.         return true; //reaching this point means that the faction has all required resources
13.     }
14.  

This is what I have but it always return false, where am I going wrong? I believe this is due to the foreach inside of the foreach. But how can I run the search of the second (PlayersResources) list to return the same Resource?
