Processing Game

2010-02-19T13:20:00.000-05:00

I finally made some headway in producing a game concept I have been thinking about for a while. Its my modified version of a game mechanic that has been around for a while. I saw an implementation of the same mechanic in a mini game in Time Splitters 2 that I liked. I reproduced the vector feel of the mini game and changed the flat landscape from that one into a circular one, a planet. I've tried to code something like this many times without a lot of success.

I stumbled across Kokoromi's call for submissions for consideration in GAMMAIV shortly after starting again on my coding. The deadline, which was less than a week away, gave me enough motivation to finish.

It also caused me to produce some pretty messy code, though I am satisfied with what I accomplished in that short time. I used this method to rotate my points and simple multiplication for the zoom as opposed to the built in Processing transforms which tend to confuse me. A lot of sin and cos were used for gravity, thrust, etcetera including this little gem I found somewhere -- sin(pangle-angle2) -- to compare angles without wrapping problems. This code on Processing Hacks handles collisions.

It was suggested that the games be kept secret until they were exhibited or until we got word they were not selected. Check out the other non-selected games currently being collected in this forum post.

Big Update

2009-12-18T16:42:00.001-05:00

Tonight I'm "going live" with an update to my main site (which is what you are looking at right now, hopefully, after being redirected from r6753.blogspot.com) which contains all my new work. Since creating the new site I haven't got around to doing a lot of Processing but I have uploaded a new sketch in honor of the big update.

It may not seem like a big update, but it was quite a pain. This site (accessible via http://r6753.com although it is currently at http://studentpages.scad.edu/~rbraue20) now pulls my posts from Blogspot. I'm using Magpie which in turn uses a PHP library called Snoopy that acts like a web browser usable inside scripts. Snoopy gets the feed and Magpie formats it for display. I'm not sure if its the best solution as the project looks a little run down but it seems to work okay so far. It seems to lag behind a little on the updating with new posts. I don't know how its cache system works and its not to well documented.

r6753.com improvements

2009-06-10T16:58:00.003-04:00

Worked on some little things on the site today and added to the RSS to make it more compliant. The dates on the RSS are approximate upload dates. Last time I put up new work I uploaded a batch of stuff I had done in the previous couple of months. Now my RSS thing reads the "last modified" dates on the files, so I just touched them with times a minute apart in the order I wanted.

I've been trying to work on a project that is more extensive than my usual explorations so I could maybe learn some new Java stuff. I hope to have it up sometime in the near future.

As you can see I haven't posted much of anything lately. You haven't missed much, but I do have a new site up for my sketches and other work:

r6753.com

I will probably continue the blog separately from the gallery site. I haven't decided what exactly I want to do yet so there are not links back here on the gallery site.

Bear with me I'm still working on it. If you have problems with it please email r6753.com@gmail.com. I've added an RSS feed but I have to get the domain fowarding/masking set up right so my meta and link tags will work.

prime music

2008-09-02T11:59:00.005-04:00

Here it is as promised. Press 'm' to change the view mode. Note that the zoomed mode was a little twitchy when tested on Firefox 2.x but fine in 3.x. Press ']' and '[' (keys 93 and 91) to increase or decrease playback rate. Press space to play / pause.

While paused press '-' or '=' or numberpad '-' or '+' (keys 45, 61, 43) to increase or decrease the number of rows. To set the number of columns type a three digit number between 3 and 120. For 57 as an example, type 057 and then enter/return. It doesn't give you feedback on what you have typed until you hit enter. If you get mixed up hit backspace or delete to clear and start over.

WIP: Prime Number Music

2008-08-24T16:18:00.003-04:00

The next project in progress here is a data-player of sorts that creates MIDI music from prime numbers (or any other sequence on ints) as input. It was first executed in V4. Preview it here: http://vvvv.org/tiki-index.php?page=UserPageRick

discs + blog status

2008-07-14T17:02:00.007-04:00

Discs is a sketch that came out of more experimentation with agents. In this setup the agents can see and individually identify others in their site range. The possibilities of this are not pushed very far in this particular sketch but it creates nice visual compositions.

A contact form is the newest addition to the blog but the layout seems to be messed up in Internet Explorer now. A javascript framework might be a good way to go. If anyone has any suggestions about how to easily avoid cross-browser inconsistency it would be highly appreciated.

This image shows how its supposed to work. Notice the right side is scrolled while the stuff on the left stays static.

agents

2008-06-27T17:04:00.007-04:00

Four-thousand software agents live and die to compose this sketch. Simple logic controls their lives. They are sensitive to the amount of dark pixels directly surrounding them and try to move towards the lighter ones. By clicking the sketch to focus then moving your mouse you can control their environment and sensitivity to overcrowding. The agents respawn in a randomly selected uncrowded location after death.

circles + backbuffer

2008-06-24T11:09:00.008-04:00

This is a fairly simple combination of my modified circles code and the backbuffer stuff from the last post.

extended patterns

2008-06-23T11:24:00.007-04:00

This is an extension on the code from the last post. This one does the same pixel operations but does them on an invisible array of pixels and streams them into the viewable area. There are also more controls on this one:

1-7 : # keys 1,2,3...7 change mode
animation position/rate :

r : random position
p : pause/unpause
- : decrease display rate (tap)
= : increase display rate (tap)

backbuffer size :

s : random size square
n : random size non-square
x : random size square > view
z : random size non-square > view
f : fill view (backbuffer 400, 400)

Information is displayed to the Java console each time a key is pressed.

patterns

2008-06-20T11:01:00.009-04:00

Patterns are generated with simple operations on each pixel in the frame. Combining the pixel index (j) with the width and height of the frame and a small incrementing decimal (count, the frame number of the animation) through modulus and scaling determines if the pixel is filled black or passed over.

pixels[floor(constrain(((j%height)*width+(j%(count*j)%width)), 0, pixels.length-1))]

press 1-7 for variations, p to pause/unpause, r to go to random position in animation

bouncing circles

2008-06-18T18:05:00.010-04:00

Seen here are some sketches that came out of exploration of the basic bouncing circles code provided for the 'Remix' my sketch post on processing.org. The first one uses straight mathematical operations on the colors which produces somewhat strange results. The second one uses more graceful color mixing and is more finished.

uses addition and modulus (which produces the "tearing") on colors

perlin experiments

2008-06-17T14:04:00.021-04:00

Here we have some Perlin noise sketches. The first two came about while heading towards the third and getting off track or screwing up. Learning about color mixing and the visual presentation of the first one was worth it:

pixels[i+j*width] = color(red(pixels[i+j*width])+a[0], green(pixels[i+j*width])+a[1], blue(pixels[i+j*width])+a[2]);

experimental processing sketchbook

2008-06-16T17:00:00.011-04:00

This is an attempt at putting together a blog with the main purpose being a gallery of Processing sketches. Some input on this as far as how it works and any other feedback would be great (maybe screenshots in your browser). It most likely has some problems and probably doesn't work very well in some browsers. This is the first successful iteration of it and the code is still sketchy.

The space to the right is an iframe that loads the auto-generated sketch sites output from Processing. It is inside a div with a fixed position so if scrolling is required the applet display box will stay in one place while the posts scroll. Each link to a sketch closes any sketch that is currently in the display box before displaying the linked sketch.
