Spotted!

After some testing, I decided to rework the radio contact rules described in the previous post. I've been playing a lot of RPG and Strategy games lately and one thing I don't really enjoy is the micromanaging aspect of buffing and de-buffing.

Rather than force the player to make hard decisions on where to allocate their buffs, it just ends up with them having to devote too many resources to support. You end up having at least one team member out of four doing nothing but support.
It also wastes a lot of time clicking and selecting and so on.

So, I want support actions to offer a significant bonus when active, but most should be passive. They should have specific utility too, not a general buff which you simply apply to your best unit. If your tanks are getting swarmed with infantry, then rapid fire will help you clear them out. If there's an enemy who is well dug in behind cover, you can use steady aim or mark target to get a bead on them.

In the end I just made special actions and ability to receive buffs reliant on having a radio. While the support role requires the command radio. Infantry can't carry a radio (yet) but they don't need to as none of their special abilities are reliant on it.

I'm also working on air support.

It's nice to be able to abstract this element. Not having to have actual planes flying around the map makes coding it a whole lot easier. Later I may add some graphics to represent it, such as a shadow cast on the ground, or an inset box with a picture of the type of plane doing the action.

Three types are currently planned; Spotter Planes, Fighter Planes and Air Strike.
In both cases they start their first turn inactive. The icon is placed on the map, but nothing happens.

On its way.
On the very next turn, the effect becomes active. Either dropping some bombs or revealing some of the map.

Circling and looking for targets.
At this time, the enemy (or the player) has a chance to use anti-aircraft weapons (or Fighter Planes) to try and cancel the effect before it is active. The chance will depend on a number of factors, such as the weapon being used, distance from target and so on.
About to head home.
The big advantage of air support is they can be targeted on tiles which are covered by fog of war. You can use them to scout out objectives or soften up the enemy before an attack. The disadvantage is that they can be nullified by opposition air support or anti air defenses.

This is quite a significant development, as none of my previous versions of Vinland got as far as adding air support rules. I hope I can train the AI to use them effectively, along with anti-aircraft weapons.

Make your game models POP with fake rim lighting.

I was watching one of my son's cartoons today and I noticed they models were using serious amounts of simulated rim lighting. Even though it wasn't a dark scene where you'd usually see such an effect, the result was actually quite effective.



The white edge highlighting and ambient occluded creases give a kind of high contrast that is similar to, but different from traditional comic book ink work.


I'll be honest, I don't know if there's a specific term for this effect in 3d design, since my major at university was in traditional art. I learned it as part of photography.


You can find plenty of tutorials on "what is rim lighting" for photography. It basically means putting your main sources of light behind your subject so that they are lit around the edges. It can produce very arresting photographs, either with an obvious effect when used on a dark subject...


..,or as part of a fully lit scene to add some subtle highlights. See how alive the subject look…

How to... build a strong art concept.

So you want to make some art assets for your game. The first on the list is a Steampunk Revolver for your main character to shoot up Cthulhu with. Quickly opening your internet browser you start with a Google image search. Ah, there is is!

It might be a good idea to find a few influences so you don't accidentally end up copying a famous design.


Just mash them up and you're ready to go! Off to your favorite modeling program.
But wait! isn't there more to building a strong design concept than that?

Of course there is.
One of the diseases of modern design is that of recursion. Everything is a copy of a copy of a copy. This is especially a problem with "historical" concepts. Over the course of that recursive process the concept becomes infected with modern design elements, and ends up looking very similar to everything else that anyone else has ever made.
If you want to come up with a really fresh idea, you have to get beyond secondary references and go look at real …

Skynet

Ok, so it's not exactly skynet, but I have got my first AI state working, kind of.


The first state is "HOLD" in which case the agent stays in place where they are and shoots at any unit that comes in range. When I started writing this module, I found that the existing method of triggering actions wasn't good enough to allow the AI to choose the best weapon or target. It worked by simply sending a command to the unit to trigger the currently selected action.

If the action is valid, it triggered, if not it didn't.
That's fine for play controlled units, as that's all they need to do. But AI needs to know in advance if the action is valid. The player can get that info from UI feedback, but that wasn't available to the AI player.

There were three problems:

1. The UI feedback duplicated code in the action trigger function. These  two sets of code could get out of phase so that UI feedback was wrong.

2. The action trigger didn't give enough feedback for …
