Ok, so I have several Scriptable Objects that are policies for governance, and each one has a public Sprite named 'icon' and a category and several float values. In another C# script (a MonoBehaviour) I'm trying to set an Image's sprite to that icon, but in my editor it says "Policy does not contain a definition for 'icon'..." but all the other values come up just fine, just not the Sprite.

Here's my Policy Scriptable Object code:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

[CreateAssetMenu(fileName = "New Policy", menuName = "Colony/Policy")]
public class Policy : ScriptableObject
{
    public string policyName;
    public string description;
    public enum Category { Health, Happiness, Control, Espionage, Defense, PopulationGrowth, Production, Research, Agriculture, FactionSpecific }
    public Category category;
    public float happinessModifier;
    public float healthModifier;
    public float controlModifier;
    public float espionageModifier;
    public float defenseModifier;
    public float productionModifier;
    public float researchModifier;
    public float agricultureModifier;
    public float populationGrowthModifier;
    public float diplomacyModifier;
    public Faction.FactionID factionID; // FactionID of faction that can use this policy (if faction-specific)
    public Sprite icon;
}

And here's the code where I'm trying to access the icon Sprite:

void ApplyPolicyFromDropdown(TMP_Dropdown dropdown)
    {
        int selectedIndex = dropdown.value;
        if (selectedIndex > 0) // Ignore "Select Policy"
        {
            Policy selectedPolicy = dropdownPolicies[dropdown][selectedIndex - 1]; // Offset by 1
            policyImages[selectedPolicy.category].sprite = selectedPolicy.icon;   //here is where my code breaks - says does not contain definition for 'icon'
            policyManager.ApplyPolicy(selectedPolicy);
        }
    }

            policyManager.ApplyPolicy(selectedPolicy);
        }
    }

• c#
• unity-game-engine

• Try changing from if (selectedIndex > 0) to if (selectedIndex >= 0) In c# index can be zero. – jdweng Commented Mar 9 at 19:52
• @jdweng but if it were 0, his -1 would make it invalid :D – BugFinder Commented Mar 9 at 19:56

Turns out all I had to do was restart my editor - Visual Studio wasn't seeing the changes in the Policy Scriptable Object for some reason.
