Cutting the trees, blacksmithies and trebuchets

Right, today was the hottest day ever in the Netherlands and tomorrow, they expect another record, so what did I do? I only worked on Holocene in the morning and now, in the middle of the night, right before going to bed, here's what I made.

Most of the stuff I've been working on is work in progress, except for turning trees into animals, like I announced yesterday. Turning trees into animals allows easier implementation of changing states. Trees will yield wood as resources, but only after cutting them. So first we're looking at a stationary unit and when it dies, it'll change into a resource object that has an animation and all the stuff we expect from resources. This is how it now looks.

The other thing I've been working on is trying to have the guy to the left have any say in the fall of the tree. The aim is to allow the unit to interact with the tree and then cut it. There are some different kinds of objects to interact with which will all need slightly different ways to do so. for instance, there's the ground and if you right click there with a unit selected, you order the unit to go there. If you right click on a building you own, you move the guy to the edge of the building and see if the building has any interaction of its own, like healing the unit or fortifying the building. If you right click on an enemy unit, you run to it and attack it. And if you right click an tree, you go towards it and start dealing damage.

In theory, this all works fine, but somehow I experience problems having the BigBookBasic script  find out what kind of object it is. Apart from the ground, all clickable objects derive from a WorldObject class, for now in this way:

• Building
• IncompleteBuildings
• Units
• Resources

All of these could have different members. A Barracks and a Wall are both buildings, A Worker and a Warrior are units and Rocks and Berry Bushes are resources. Further, Units could be animals too. BigBookBasic will need to find out what kind of object we're looking at a a certain moment. Well, that does not yet work. I'm sure I'll figure it our, but not today and I'm also sure that I need to figure it out soon, because it's central to give units the information they need to decide what to do with an order. In other words, I think this part of the program is what will turn it into a game. 

When I get this to work, there'll be some refactoring needed, because I have some scripts, like the gather script, that do work, but it a roundabout way and I have different variables to track target unit, building, resource and "object" for units. I want them in one variable. For that I made a small class to store both the object itself and some information on it. This class will be the main focus in interactions between objects.

In short, the trees do fall and turn into resources. I cheated, because you see the health bar decrease, but that's just because I added some testing code. Sneak preview perhaps, or will I delete it later?

    protected override void Update()
    {
        if (Input.GetKeyDown(KeyCode.T))
        {
            DamageHealth(10);
        }
        base.Update();
    }
