Tag Archives: Vector3D

So Chris’s book Real-World Flash Game Development introduced some concepts that I am not familiar with.  In particular vectors (like arrays, only typed), Vector3D (a way of calculating motion), and interfaces (I still don’t understand this) are new to me.  I understand vectors, those are not hard.  Vector3D was a little challenging to grasp, but I sat down with them today and after a couple hours I had programmed a little interface for making an avatar jump around the screen.  I used Chris’s book extensively for this, but wrote my own class using his as a reference.  I’m happy with the result and am even more happy that I understand it myself.  It always takes a little playing on my part before I really grasp a concept.

On the flip side, I still don’t understand interfaces for classes.  It seems like a lot of people speak of them in vague terms without a direct, appropriate, real-world example.  I think that’s why they’re hard to grasp.  But I’ll keep looking.

So in conclusion, I made some progress that I’m happy with.  Yesterday was really frustrating and I was questioning whether I should really be building my own classes or not.  But today with the progress I’ve made I’m confident in my decision and direction.  If I can tackle one or two problems like this each day, I should have a base game engine in a week or two.
