Last time I talked about serialization of C++ objects to and from an abstract archive format, using a templated interface similar to Boost Serialization. This time I want to get a little more specific and explain how objects can be converted to JSON (http://www.json.org/).

It's quite instructive to …

Getting data into a game is a big subject and I want to talk about some of the systems I'm using in some detail, so it may take a few posts to get through it. I will narrow the subject a little first though: this is not going to be about asset loading - textures, meshes, sounds and so on. Rather it…

Squad movement is looking ok now.

Given solid pathfinding code and physics, it was already working reasonably well in that units could simply push other units out of the way to get where they wanted to go. It just didn't look that good. I chose a simple solution; as my squads are quite small I don't…

Squad movement is giving me a bit of trouble.

I've got it working fine for one unit, but I want to select several units together and have them move as a group, without getting in each other's way. My first thought was to pick the closest unit to the destination, make that the leader, and have the ot…

My GUI is sort of done. Well, code is never really finished, but it's functional and I'm looking at other things now.

As it's almost stand-alone, I'm releasing the source too:

Here's an implementation of A* in C++ which hopefully works and is quite sensible.

Note that

• It doesn't use a million templates, or any for that matter (except std containers).
  
• It doesn't do stupid things like trying to erase out of the middle of a queue.
  
• It assumes nothing about data structures so is …
