2D filters and effects.

I did some work on particle systems earlier this month, and today I tried out coding some 2D GLSL filters.

The effect I wanted was a kind of localized distortion. Initially I wanted it for spell effects, but the required set up is too cumbersome and would require multiple layers of filters for different spell effects. In the end I decided it would make a good effect for representing monsters with magical radiation.

In the game world, magic is pretty dangerous stuff. You can get irradiated by using it, and it drains your focus, dropping you in to a coma or even death if you receive a lethal dose.

There are some monsters though who are suffused with magic. These will be dangerous opponents as they are effectively radioactive.

I think it's a fun game mechanic for making bosses more interesting. I can think of a number of ways it can be used to make things interesting tactically. And it could also be used as a kind of environmental hazard. It could be good for dynamic puzzles, similar to the anomalies in STALKER.

There are a few other filter effects I can use to buff up some of the later enemies, I want to make them more individual, and seem more powerful in their spell like abilities.

Usually such filters are usually just after thoughts, just to make the game look better. However, if you know what effects are available, you can use them more creatively to create more believable gameplay mechanics. After all, I could just use a light to illuminate a monster to show radiation, but the more disturbing effect offered by the 2d filter makes the player really feel the threat from such a creature.

It feeds in to the psychological effects mechanic I want to include too. If I want to make fear a real aspect of the game, I've got to imbue the more terrifying creatures with more of an impressive aura, If they are just glowing with a green light, it's not very scary, but if they look like they are half way between dimensions, tearing at the very fabric of reality... Then you've got really scary monsters.

    1. Thanks for the help, I tried the blogger recommended way of embedding videos, but it didn't work. From now I'll be posting an image related to the video and giving it a link.

  2. The second one with the 2d displacement effect looks great.

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 …
