Almost There

This summer is when we’ll really get down to business. So far I’ve just been picking at unimportant pieces of code, and the team has been going over design decisions and some more meta stuff unrelated to the core game itself, but rather to our company.

Work will start sometime late next week. There’s college work to get out of the way before then.

World Map Generator

Had to rework it a bit so that it would wrap around the globe this time. The colors are very rough, just for testing. We’ll have tiles ready soon.

So now, you’ll be able to move across the world in just one direction and end up where you started.

Lighting Stress Test

While at the studio I did tons of work organizing some internal… stuff. Nothing I can really show. So, at the end of the day, I decided to put the lighting system through its paces. I put a shadowed light source on each of 40 blue guys, who move around constantly. This was the result. And it ran fine!

It made me think there could be a dungeon or cave full of phosphorescent plants that light up like this. There’s lots of cool things we can do with the lighting.

Wrap Battle

I got to thinkin’ about the world map.

I thunk to myself, “Gee wiz, I’d sure like for it to loop around like an actual globe.”

So I did this in preparation.

Don’t worry, I can turn it off and on with a simple change of a number.

Turn Ordering Complete

This feature is an example of one of the advantages to rewriting a game.

In the Game Maker version, I hardly knew what I was doing when I started writing the turn controller. By the time I had realized what I SHOULD have done, it was too late to actually DO it.

But now it’s so much easier to work with.

I will list the ways.

-The player actor is now no longer treated as a special interrupt case by the turn controller. Which cleans up the code quite nicely.

-Any actor is now capable of pausing the simulation for its turn if it needs to. Turns must be explicitly ended by the actor itself, not the turn controller.

-There is now the feasibility of controlling multiple characters (or multiplayer?!) by simply adding another player actor on the scene. There’s no need for any other setup conditions.

-A pointer to the actor who’s turn it is is now available.

-The “simulations-per-frame” (game speed) variable is more optimized. Dealing ONLY in game turns, and not any other frame-by-frame logic events, like lighting updates and key presses.

-And to top it all off, turn delays/cooldowns for various actions and default game simulation speed are both increased in order to make the timing more precise.

Blue Man Group

In order to make way for the ability to add more than one kind of character in the game, I had to refactor and add a lot of things to the base actor implementation, so it took a while. Now that it’s squared away it’ll be easier to do the same thing for other kinds of objects in the game, since now I have a sort of template I can go back to and see “oh right, that’s how I set that up…”

Anyway, I tested this by adding about fifty of these A.I. controlled blue guys who just zip around the screen really really fast. Surprisingly, the framerate was also really really fast, despite all those pathfinding calls. It’s good to know that a bunch of actors on screen doesn’t slow anything down. Especially good seeing as how the actors were having their A.I. logic run about 50-100x more often than would be in an actual gameplay scenario, which is turn-based and slowed down.

Today’s Additions

I figured out a much more elegant way to save game data than what was in the previous GM version.

Each object defines its own behavior for how it saves itself to a file. This allows me to make a file that JUST stores data for a single actor, or a single tile. I can also store data for more abstract objects, like the game world itself, or the player’s current session. As well as calling functions to write its own data to a file, it will call the save functions of the objects it “owns”. It creates a convenient, modular chain that’s easy to change as I go.

I finished up a quick and dirty implementation of this today, and it works! Hopefully, it stays that way.

The next task is to take care of the message log. In the GM version, whole lines could be colored. In this version I will attempt to allow per-character coloring using formatted strings of text.

The text shaping options in Allegro 5 are quite limited, so this is going to be frustrating getting it to fit the dynamically-sized UI. To alleviate some of the pain, I’ll be using a monospaced font for the message log.

Lighting Engine Complete?

Sure seems like it. Got it done in one day!

Now that shadow-culling and day/night cycling is in place, Clarion’s new lighting engine is ready for action.

It allows me to have a virtually unlimited number of shadowed lights at almost no performance cost, which will make environments in the game far better looking. Especially dark dungeons with sparse lighting. The size of the lights are also improved, which frees me from the original annoyance of severely limiting the player’s field of vision in the last version.
