  • RPi and Java Embedded GPIO: Sensor Connections for Java Enabled Interface

    - by hinkmond
    Now we're ready to connect the hardware needed to make a static electricity sensor for the Raspberry Pi and use Java code to access it through a GPIO port. First, very carefully bend the NTE312 (or MPF-102) transistor "gate" pin (see the diagram on the back of the package or refer to the pin diagram on the Web). You can see it in the inset photo on the bottom left corner. I bent the leftmost pin of the NTE312 transistor as I held the flat part toward me. That is going to be your antenna. So, connect one of the jumper wires to the bent pin. I used the dark green jumper wire (looks almost black; coiled at the bottom) in the photo. Then push the other 2 pins of the transistor into your breadboard. Connect one of the pins to Pin # 1 (3.3V) on the GPIO header of your RPi. See the diagram if you need to glance back at it. In the photo, that's the orange jumper wire. And connect the final unconnected transistor pin to Pin # 22 (GPIO25) on the RPi header. That's the blue jumper wire in my photo. For reference, connect the LED anode (long pin on a common anode LED/short pin on a common cathode LED, check your LED pin diagram) to the same breadboard hole that is connecting to Pin # 22 (same row of holes where the blue wire is connected), and connect the other pin of the LED to GROUND (row of holes that connect to the black wire in the photo). Test by blowing up a balloon, rubbing it on your hair (or your co-worker's hair, if you are hair-challenged) to statically charge it, and bringing it near your antenna (green wire in the photo). The LED should light up when it's near and go off when you pull it away. If you need more static charge, find a co-worker with really long hair, or rub the balloon on a piece of silk (which is just as good but not as fun). Next blog post is where we do some Java coding to access this sensor on your RPi. Finally, back to software! Ha! Hinkmond

  • Using copyrighted sprites

    - by Zertalx
    I was thinking about making a pacman clone, I know there is a similar question here Using Copyrighted Images , but I know i can't use the original art from the game because it belongs to Namco, so if I design a character that has the shape of the slice circle it will look exactly like pacman, maybe if I use green instead of yellow? Also if the game plays like the original pacman, it is wrong? I just want to make the game as a personal project and and publish it in my site without getting in trouble

  • How to implement an intelligent enemy in a shoot-em-up?

    - by bummzack
    Imagine a very simple shoot-em-up, something we all know: You're the player (green). Your movement is restricted to the X axis. Our enemy (or enemies) is at the top of the screen, his movement is also restricted to the X axis. The player fires bullets (yellow) at the enemy. I'd like to implement an A.I. for the enemy that should be really good at avoiding the players bullets. My first idea was to divide the screen into discrete sections and assign weights to them: There are two weights: The "bullet-weight" (grey) is the danger imposed by a bullet. The closer the bullet is to the enemy, the higher the "bullet-weight" (0..1, where 1 is highest danger). Lanes without a bullet have a weight of 0. The second weight is the "distance-weight" (lime-green). For every lane I add 0.2 movement cost (this value is kinda arbitrary now and could be tweaked). Then I simply add the weights (white) and go to the lane with the lowest weight (red). But this approach has an obvious flaw, because it can easily miss local minima as the optimal place to go would be simply between two incoming bullets (as denoted with the white arrow). So here's what I'm looking for: Should find a way through bullet-storm, even when there's no place that doesn't impose a threat of a bullet. Enemy can reliably dodge bullets by picking an optimal (or almost optimal) solution. Algorithm should be able to factor in bullet movement speed (as they might move with different velocities). Ways to tweak the algorithm so that different levels of difficulty can be applied (dumb to super-intelligent enemies). Algorithm should allow different goals, as the enemy doesn't only want to evade bullets, he should also be able to shoot the player. That means that positions where the enemy can fire at the player should be preferred when dodging bullets. So how would you tackle this? Contrary to other games of this genre, I'd like to have only a few, but very "skilled" enemies instead of masses of dumb enemies.

  • Randomly generate directed graph on a grid

    - by Talon876
    I am trying to randomly generate a directed graph for the purpose of making a puzzle game similar to the ice sliding puzzles from Pokemon. This is essentially what I want to be able to randomly generate: http://bulbanews.bulbagarden.net/wiki/Crunching_the_numbers:_Graph_theory. I need to be able to limit the size of the graph in an x and y dimension. In the example given in the link, it would be restricted to an 8x4 grid. The problem I am running into is not randomly generating the graph, but randomly generating a graph, which I can properly map out in a 2d space, since I need something (like a rock) on the opposite side of a node, to make it visually make sense when you stop sliding. The problem with this is that sometimes the rock ends up in the path between two other nodes or possibly on another node itself, which causes the entire graph to become broken. After discussing the problem with a few people I know, we came to a couple of conclusions that may lead to a solution. Including the obstacles in the grid as part of the graph when constructing it. Start out with a fully filled grid and just draw a random path and delete out blocks that will make that path work. The problem then becomes figuring out which ones to delete to avoid introducing an additional, shorter path. We were also thinking a dynamic programming algorithm may be beneficial, though none of us are too skilled with creating dynamic programming algorithms from nothing. Any ideas or references about what this problem is officially called (if it's an official graph problem) would be most helpful. Here are some examples of what I have accomplished so far by just randomly placing blocks and generating the navigation graph from the chosen start/finish. The idea (as described in the previous link) is you start at the green S and want to get to the green F. You do this by moving up/down/left/right and you continue moving in the direction chosen until you hit a wall. In these pictures, grey is a wall, white is the floor, and the purple line is the minimum length from start to finish, and the black lines and grey dots represented possible paths. Here are some bad examples of randomly generated graphs: http://i.stack.imgur.com/9uaM6.png Here are some good examples of randomly generated (or hand tweaked) graphs: i.stack.imgur.com/uUGeL.png (can't post another link, sorry) I've also seemed to notice the more challenging ones when actually playing this as a puzzle are ones which have lots of high degree nodes along the minimum path.

  • Genetic Considerations in User Interface Design

    - by John Paul Cook
    There are several different genetic factors that are highly relevant to good user interface design. Color blindness is probably the best known. But did you know about motion sickness and epilepsy? We’ve been discussing how genetic factors should be considered in user interface design in one of my classes at Vanderbilt University School of Nursing. According to the National Library of Medicine, approximately 8% of males and 0.5% of females have red-green color discrimination problems with the most...(read more)

  • How do I disable network connection at prelogin?

    - by ProGNOMmers
    --- This question is related to Ubuntu 12.10, since previous versions did not connect to network before login --- I had a bad boot today: the Ubuntu screen was blocked at startup time, after a green [OK] and a white blinking underscore. In recovery mode I figured out the problem: NetworkManager hung trying to connect to a wireless network that wasn't available anymore, and so I couldn't reach the prelogin level. Anyway: I really don't like that the pc connects to a network before the user logging in. How is it possible to disable it?

  • Ubuntu Lock Screen Conflict with Google Chrome

    - by S.K.
    I don't know if this is a "feature" or not, but when I lock my screen in Ubuntu (GNOME 3), if Google Chrome needs to show a JavaScript alert (like if I set a reminder for an event in Google Calendar), Chrome will show up on top of the lock screen. If you'd like to simulate it, try running this JSFiddle, just click on the green box and lock your screen before the alert shows up - http://jsfiddle.net/skoshy/ZYSYr/ Anyone know how to fix/avoid this?

  • I get GL_INVALID_VALUE after calling glTexSubImage2D

    I am trying to figure out why my texture allocation does not work. Here is the code: glTexStorage2D(GL_TEXTURE_2D, 2, GL_RGBA8, 2048, 2048); glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, 2048, 2048, GL_RGB, GL_UNSIGNED_SHORT_5_6_5_REV, &BitMap[0]); glTexSubImage2D returns GL_INVALID_VALUE but the maximum texture allowed is 16384x16384 on my card. The source of the image is 16bit (Red 5, Green 6, Blue 5).

  • Defining and selecting an area from an image

    - by meth0d_
    I want to create a game, where the world is loaded from an image file, much like Paradox Interactive does it for their games. If I have this image: Then the red, green, blue, cyan, magenta, white, black and grey should be different provinces. I know how to loop through them, and check if it's a new province, the problem is that I don't know how to define the region of the province for selection: I don't know how I can load in data, to make sure you can click anywhere on that province, and make sure it gets selected.

  • WCF Routing Service Filter Generator

    - by Michael Stephenson
    Recently I've been working with the WCF routing service and in our case we were simply routing based on the SOAP Action. This is a pretty good approach for a standard redirection of the message when all messages matching a SOAP Action will go to the same endpoint. Using the SOAP Action also lets you be specific about which methods you expose via the router. One of the things which was a pain was the number of routing rules I needed to create because we were routing for a lot of different methods. I could have explored the option of using a regular expression to match the message to its routing but I wanted to be very specific about what's routed and not risk exposing methods I shouldn't via the router. I decided to put together a little spreadsheet so that I can generate part of the configuration I would need to put in the configuration file rather than have to type this by hand. To show how this works download the spreadsheet from the following url: https://s3.amazonaws.com/CSCBlogSamples/WCF+Routing+Generator.xlsx In the spreadsheet you will see that the squares in green are the ones which you need to amend. In the below picture you can see that you specify a prefix and suffix for the filter name. The core namespace from the web service your generating routing rules for and the WCF endpoint name which you want to route to. In column A you will see the green cells where you add the list of method names which you want to include routing rules for. The spreadsheet will workout what the full SOAP Action would be then the name you will use for that filter in your WCF Routing filters. In column D the spreadsheet will have generated the XML snippet which you can add to the routing filters section in your configuration file. In column E the spreadsheet will have created the XML snippet which you can add to the routing table to send messages matching each filter to the appropriate WCF client endpoint to forward the message to the required destination. Hopefully you can see that with this spreadsheet it would be very easy to produce accurate XML for the WCF Routing configuration if you had a large number of routing rules. If you had additional methods in other services you can simply copy the worksheet and add multiple copies to the Excel workbook. One worksheet per service would work well.

  • Validation and Error Generation when using the Data Mapper Pattern

    - by AndyPerlitch
    I am working on saving state of an object to a database using the data mapper pattern, but I am looking for suggestions/guidance on the validation and error message generation step (step 4 below). Here are the general steps as I see them for doing this: (1) The data mapper is used to get current info (assoc array) about the object in db: +=====================================================+ | person_id | name | favorite_color | age | +=====================================================+ | 1 | Andy | Green | 24 | +-----------------------------------------------------+ mapper returns associative array, eg. Person_Mapper::getPersonById($id) : $person_row = array( 'person_id' => 1, 'name' => 'Andy', 'favorite_color' => 'Green', 'age' => '24', ); (2) the Person object constructor takes this array as an argument, populating its fields. class Person { protected $person_id; protected $name; protected $favorite_color; protected $age; function __construct(array $person_row) { $this->person_id = $person_row['person_id']; $this->name = $person_row['name']; $this->favorite_color = $person_row['favorite_color']; $this->age = $person_row['age']; } // getters and setters... public function toArray() { return array( 'person_id' => $this->person_id, 'name' => $this->name, 'favorite_color' => $this->favorite_color, 'age' => $this->age, ); } } (3a) (GET request) Inputs of an HTML form that is used to change info about the person is populated using Person::getters <form> <input type="text" name="name" value="<?=$person->getName()?>" /> <input type="text" name="favorite_color" value="<?=$person->getFavColor()?>" /> <input type="text" name="age" value="<?=$person->getAge()?>" /> </form> (3b) (POST request) Person object is altered with the POST data using Person::setters $person->setName($_POST['name']); $person->setFavColor($_POST['favorite_color']); $person->setAge($_POST['age']); *(4) Validation and error message generation on a per-field basis - Should this take place in the person object or the person mapper object? - Should data be validated BEFORE being placed into fields of the person object? (5) Data mapper saves the person object (updates row in the database): $person_mapper->savePerson($person); // the savePerson method uses $person->toArray() // to get data in a more digestible format for the // db gateway used by person_mapper Any guidance, suggestions, criticism, or name-calling would be greatly appreciated.
