Coding general AI.

As promised I've spent most of my time this week
on coding basic gameplay.

[text above each agent displays debug info]
I started out having separate state machines for AI decision making and actions/animation.

Sometimes AI control calls for very rapid switches of states which would also disrupt the animations. Causing them to stutter or jump.


But by setting up Animations to only switch after a short delay I eliminated the problem you get with having AI and actions in the same state.

If a call to switch animation occurs, but rapidly switches back (like stopping for an instant when walking) the switch is ignored.

So I refactored them in to a single finite state system with inheritance helping to structure things like animation and path finding.


[Blocked in!]
AI is pretty basic. They just try to get towards you avoiding squares they've already visited. But it works surprisingly well.

It's easy to get blocked in by the enemy, but you can use the nature of the grid to avoid fighting too many enemies at once.

I don't know how well this system will work once I introduce the other party members. That's going to take some serious testing to see if it's fun or not.

[Big and small agents interact seamlessly]
 I added the ability to rotate the camera 90 degrees, this keeps the WASD movement system working well, but allows you to see behind things or get a better view.

Controls are going to be all keyboard based, with a radial menu handling things like item use, switching control of party members, resting, using special abilities etc...

There will probably be a shortcut bar too, so you can map some short cuts to the number keys.

[Water shader]

I did spend some time this week mucking about with shaders again, but there seems to be some kind of bug when rotating the camera. Sigh.


You know, it's funny that shader isn't in the spellchecker dictionary...

Vinland 1936

What have I been up to this month?

Well you can see it in a couple of development blog videos, here, here and here.

Vinland 1936 is a game I've been working on (on and off) for about 3 years. It is somewhat based on the old Nirval interactive game, Blitzkrieg;





I hope you've played it since it is one of the best games ever!!! (IMHO)
Blitzkrieg was a real time tactics game. You didn't build a base, or spawn units. It wasn't about rushing the enemy. You got a small number of troops and vehicles that could be replenished or repaired if you had access to a supply base and the right supply trucks, but couldn't be replaced if lost. Once your vehicles were destroyed and your infantry killed you were finished. You couldn't just churn out some more from your factory and have another go at rushing the enemy guns. This made you invest a lot in each of your units. They really mattered.

It was also procedurally generated. Each mission (except for the historical missions) was…

Reboot / Remake / Restart

Although the roguelike project was going well I had a few issues with some parts of the code, and the sheer size of the project was something I could see stretching away in front of me for years with no guarantee that people would actually want to play it when it's finished.

It's time to try something a little less ambitious.
I'm going full rogueLITE!

Using a lot of the code from the roguelike project, I started making a more limited game.
There will be a single character, combat will be more arcade like, there will still be a chance to upgrade and develop your character's stats, but they represent only a single class and have fixed equipment.

I've got a fun character, an interesting setting and an exciting story lined up. It still utilizes my low poly style, but things are going to be a little more cartoony.

Game play involves mostly chucking bombs at the enemy.

But there's also a lot of platforming, jumping from multiple levels is part of the game. And you ca…

Telling a story; Creating a Compelling Narrative.

Telling a story; Creating a Compelling Narrative. In this blog I will talk about my own recent brush with story telling and go on to talk about how tools from creative wring can help you to better author the narrative in your games, whether they have a traditional linear narrative or a procedurally generated interactive narrative.

Narrative and structure in traditional fiction  last week I started writing a story set in the world I'm developing for my game Vinland: 1936.

I hope the story will help me to flesh out my game world and develop my own expanded universe which will be a good place to set my games in the future.

After about a week of work, on and off I've progressed the story to outline stage. For each character thread I have half a dozen chapters which plot a course through the events of the story. Each thread is told from the perspective of a different character.


Actually I started writing as soon as I had my outline, but I've since gone back and deleted what …
