Space Invaders: Physics Revisit

So I've started looking at the physics implementation that I currently have in the JBEngine. It uses Physx but when I initially integrated it I must have literally got it working for the exact case that I needed it and then left it. I think that came from my inexperience in programming in general.

After looking through the code and playing with a few things I have managed to get the enemies to have box collision shapes and also have the update from physics to game scene working fairly well. 

I will definitely need to re-factor quite a bit of this code to get it to work in a way that would integrate a little easier with an Entity Component System. I have been thinking a little about my current design and have also made the code that was already there a little more flexible. 

I also got to look at this beauty again as well... The Physx Visual Debugger! It is pretty finicky to manoeuvre the camera but it does show a clear representation of your physics scene which is really good. Unfortunately I couldn't get a video of the physics objects moving so this screenshot will have to do. 

I think the next post will be mostly about the design that I am going to implement before I dive in and start coding. I don't want to make the same mistake as last time ;) 

As another note the fact that Unity uses Physx and also an Entity Component System may make my life a little easier as I can see how they have done it and take some guidance from that.

Would be great to get this physics work integrated fully and in a flexible way soon.

Cheers :)
