Problem with inheritance and access between scripts.

Questions & Answers
1

So I’m making an RTS game and I’m running into problems with inheritance. I’m going to strip to the basics to make the question more simple.
So I have four scripts,

Building_Main.cs

BuildingA.cs which inherits from building_Main

Base_Unit.cs

Soldier.cs - which inherits from Base_unit.
Building_Main has some methods that draw gui and builds the building queue which work perfectly.

So Building A’s start code looks like

  public GameObject x;    
  void Start () {
      base.unit = x;
 }

so x is the unit building A will produce. x is a gameobject in my assets folder, with the soldier.cs script attached. I attached building_A to an actual gameobject in the world and dragged the prefab soldier from my asssets and put it in x.
This is the Base_Unit script

    protected float health { get; set; }
    protected float speed { get; set; }
    protected int level { get; set; }
    internal float buildTime { get; set; }
  
    void Start () {
	    
	}
	
	// Update is called once per frame
	void Update () {
	
	}

This is the Soldier.cs which inherits

 void Start () {
            base.health = 10;
            base.speed = 10;
            base.defense = 10;
            base.buildTime = 10;
    	}

As you can see, soldier sets its building time to be 10.

The problem occurs in Building_main’s addToQueue function whose code is below:

public void addToQueue(GameObject bug)
    {
        buildQueue.Add(bug);
        Debug.Log("Adding to the queue, a build time of " + unit.GetComponent<Base_Unit>().buildTime); 
     
    }

Remember unit is what building_A sets to soldier in its start function.
However buildtime comes to be 0 even thought it should be 10.
Am I approaching this wrong? I have no idea how to proceed further. Please let me know if the question isn’t clear enough.

I’m not 100% sure but i think you might not be using the solider as intended.

 base.unit = x;

That just creates a reference in your file pointing to another reference. But neither reference is actually pointing to an “actual” object. You might need to instantiate a solider, THEN set it to base.unit = x.
