Progress Update September 2016

Where to begin? Not long after my last post, development on Bulldog stalled badly. I had a few other game ideas kicking around and after some soul searching I decided to put Bulldog on the backburner for a while and start developing one of the more promising (and less ambitious!) ones. I made some good progress, and even trialled some changes to my development process.

At my day job as a developer we've been transitioning over to a Test Driven Development process. I've embraced a lot of these ideas, such as Dependency Injection and Mocking for my part-time games development. Its really shown me where I went very wrong with Bulldog's development from the outset.

Now, fast forward 6 months or so and I'm about to abandon the new project, (code-named "Collie") and switch back to Bulldog again. What the hell?!

This is for several reasons:

  1. My design for Collie isn't really mature enough. 
  2. While working on Collie, I never stopped thinking about Bulldog, and kept coming up with cool new ideas for it, which suggests to me that my subconscious really wants to build that game, not Collie. 
  3. I've hit a bit of a wall and can't find motivation to continue on Collie at the moment. Perhaps related to #2?

So... you wasted seven months?

Not exactly. Working on a new code base, it really illustrated to me the problems I was living with in Bulldog, and as mentioned earlier, I can really see where I've gone wrong with singletons and statics all over the place.

I'm excited about getting Bulldog back on track again, and have great plans for resuming development and refactoring the codebase to correct my previous mistakes that prevent proper unit testing etc.

I've also learnt a lot about focussing on the value of new features, and developing the most crucial things first, not the coolest or hardest ones.

On this note, I came to the schocking realisation recently that Bulldog is at its core supposed to be a survival game, but after 5 years of development, I haven't coded the ability for the player to die yet! I've got procedurally generated terrain, real time shadows, pathfinding, a custom UI, status effects, loot tables etc. But if the player's health hits 0, the game locks up. What the hell?!

So yeah, I'm coming back to the project with a healthy dose of "What the hell was I thinking?", a fresh perspective, some new development skills and a rewnewed passion for making this game.

Progress Update February 2016

As is rapidly becoming the norm, I've scope-creeped the hell out of this latest snapshot. I'd intended to wrap it up just before Christmas, but here it is, 2 months later and I've still got over a month of dev to go. I made the mistake of starting work on a feature I didn't have a really solid design for. I thought I could "wing it" and the gaps would naturally fill themselves in, but I hit a few issues that basically blew that out of the water. I've sorted out the design now, but there's more work to be done before I can tick crafting off my todo list.

I changed my mind re: the UI redesign I mentioned in my last post. It is going to be much harder to change in the future, so now is the best time. It ended up taking about 3 weeks, but I've replaced my old, half-assed layout system with a newer, more flexible one that's now using its whole ass. As a bonus I fixed a few lingering layout bugs that have been annoying me, so yay!

I've got a fairly good design & plan for the next month of development. Barring any unexpected hiccoughs, I hope to put crafting to bed and move on to some of the exciting new things I've been dreaming up over the past year.

Progress Update January 2016

Happy new year everyone!

What have I been up to since October? Less than I would have liked. However, I've made some excellent progress on the crafting system again, taking some influence from games I've been playing recently. Unfortunately I find it way too easy to make my game systems crazy complicated.

One of the risks of being a one man dev operation is you have to be your own bullshit filter. I often get so enamoured with an idea I'm working on I don't realise it will be terribly complicated for the player until I'm a decent way in. Eventually (once the shine wears off) the sanity police rock up and I drastically cut functionality and make it sane. I just wish it'd happen sooner, so I don't waste development effort. :)

On a related note, recently I've discovered some annoying issues in my codebase that are not going to be quick fixes and are preventing me from building certain pieces of functionality. They are relatively minor presentation things, so it isn't a big deal at this stage, but at some point I'm going to have to redesign my UI system to be more flexible. Not looking forward to that at all.

On a non coding front, I recently made some major breakthroughs on the backstory front. I've broadly defined the story elements that will occur leading up to the player taking control and even had some ideas for a short intro sequence to relate this to the player. Previously I had a general idea for what I wanted but there was no clear path from normal world to the game world, narratively speaking.

In the development pipeline for the future I have: Finishing off the crafting system, as well as some technical architecture things such as a procedural content system I've been itching to get going on, as well as rendering improvements such as LOD for my terrain meshes.

Until next time!

Progress Update October 2015

A while back I finished Snapshot 12. It turned out to be one of the longest snapshots I've worked on, coming out at about 8 months. Most of the changes were behind the scenes stuff, so to most users nothing has changed since the beginning of the year.

Under the hood, I've made quite a lot of changes. The biggest of which is splitting the codebase into a client and a server thread. Currently the server thread takes care of creating the initial terrain, and nothing more.  However, over the next few snapshots I'll gradually move more of the client's processing into the server, with the eventually goal of supporting multiplayer.

One of the biggest issues I encountered during that time was serialisation of gamestate. Somewhere around 2 years ago I made an error in judgement which made serialisation impossible without an extensive rewrite. I didn't notice at the time because I hadn't written any of the serialisation code yet.

In retrospect I should have implemented the save and load functions early on. This would have forced me to consider game state serialisation immediately.

So, lessons to be learned here:

1) As soon as you start creating game objects, write the code that serialises and deserialises them.
2) Maintain your serialising code. If you modify the game objects, modify the serialisers. Don't rely on coming back to it at a later date. You will forget.
3) Write unit tests to verify your serialisation/deserialisation process works correctly and then maintain them.
