It's been a couple of days since I got to writing a blog post, because I wanted to finish what I was doing before sharing it.
I was refactoring the state machine to make the state transitions easier to implement without bugs. Like it always happens, when you try to make something to prevent bugs, it'll have a major bug. And when you finally find and fix the bug, you wonder how on earth that could ever take that long! Well, that's what happened.
In short, when the worker was sent to a goat to collect the food, he immediately started harvesting and it was not until I right clicked the goat again that he went there. This was because of a couple of things:
Firstly, the mechanism for deciding if the unit arrived at the destination, that was faulty. I have this method to give a arrived-signal when the distance between unit and target is smaller than the radius of the unit plus that of the target. This is to avoid units fighting for position. Problem was that the target was a spot on the edge of the target. This means that the unit would only walk to a certain distance from the edge of the target and that was too far away. I moved the target point to the center of the target object.
Secondly - and this is that major bug - the unit started in the walking state with the destination at its own position. It would just walk to its own position and wait for instructions. I don't really see what went wrong exactly, but the unit should start in the idle state. Once I did that, it all worked again.
Other things I did were to implement a new sub class of building: storage. Every storage thing can contain a certain amount of any resource type a d it'll become a resource with some of its resources when destroyed.
I also got the amphora to look alright from the inside and not be see-through. Last, I got the UI for resources working. Next will be the UI for the selection panel to show selected objects. After that, I'll start with either building or melee fighting.
