• Castle Bash [iPad, Games] Castle Bash is a remake of Atari's 1980 arcade release Warlords, which is probably best known for its release on the Atari 2600 console in 1981. Rated the 25th greatest video game of all time by Game Informer, Warlords allows up to four players to compete in a castle defense bout that's something of a combination of Breakout and Elimination / Quadrapong. If you ask me, this looks like great fun. Castle Bash was developed by TouchGrove, who brought us the retro '70s LED Basketball [App Store] To read more, see this post by Blake Patterson on Touch Arcade.

• Horizons [iPhone, iPad, oF] Horizons is a interactive sound toy which brings together the atmospheric sounds of Eli Murray (Gentleforce) and generative visuals of Lukasz Karluk. The app is an exploration of colour, sound and form. The design of the piece focuses on creating subtle colour refractions in a rich colour scape using an algorithmic process known as triangulation. Fluidity of interaction is achieved using real-time physics made using the Box2d library and openFrameworks. Using the UIKit (Apple GUI standard) in combination with oF, you are able to modify a number of parameters in the app. These include the amount of points triangulations use, the colour of gradients as well as randomise the colour and save screens to the library. The triangles themselves react to accelerometer and are multitouch allowing you to move multiple points at the same time across the screen. In the process, Lukasz has also made some of the work available open source, including the colour picker code which you can download here. Mac version of the app + source coming soon.. The app was finally released today. We have had it for few days now and not only thats it's a joy by itself it also works great in combination with other apps if you are looking for some awesome looking gradients. A must for your app collection.. Gentleforce has also recently released his debut album "Sacred Spaces" on Feral Media which can be downloaded from iTunes.

• SpringMesh [iPhone, iPad, openFrameworks] Inspired by the natural phenomena of cloths and liquids, Ricardo Sanchez explores spring mesh dynamics using box2D physics. SpringMesh is an interactive cloth you can twist, pull and deform using multitouch or gravity. Created by Ricardo and published by apps.CAN, SpringMesh is available now in the AppStore for both iPhone and iPad as an universal app ($1.99). Features: - Tap and drag to control the deformers (multitouch supported) - Adjust spring damping, frequency and force radius - Adjust mesh appearance including fills, wireframe or points - Adjust mesh density - Gravity - mesh gets twisted according to device orientation - Change mesh color gradient - Save image to photo library - Universal - one app for all your iOS devices. For more information, see http://springmesh.creativeapplications.net For more examples, see our group on Flickr http://www.flickr.com/groups/springmesh/ (40% of proceeds go to CAN. Thank you for your support) -- Details SpringMesh was built using ofxBox2d physics addon for openFrameworks. It consists of a series of particles interconnected by springs, border particles are static allowing the mesh to maintaing its original form, while inner particles repel, attract to user input (multitouch) or fall under gravity. Its colour is a direct representation of the forces applied, the stronger the force the lighter the colour. Building the mesh The grid is build by specifying the number of horizontal cells, from it we calculate the number of vertical cells float gridRatio = gridWidth / gridHeight; rows = (int)( cols / gridRatio ); The rest fall in place with a couple of for loops, but first we calculate cell dimensions. float colCellDist = gridWidth / cols; float rowCellDist = gridHeight / rows; int idx = 0; for ( int j = 0; j for ( int i = 0; i 0 ) { Here we create horizontal connections by using the newly create particle and the previous in the container with index [idx - 1]. Store in a spring container. } if ( j > 0 ) { Vertical connections follows same principle as before but now we take the previous particle from the container with index [idx - cols - 1]. Store in a spring container. } idx++; } } -- Rendering wireframe mesh For the wireframe view we loop through the springs container, getting both sides of the spring, its colour is calculated by the separation distance of both particles for ( int i = 0; i < springs.size(); i++ ) { Get one side position springs[i].joint->GetAnchorA() Get the other side position springs[i].joint->GetAnchorB() Calculate distance between spring bodies positions to change colours float dist = bodyAPos.distance( bodyBPos ); float k = (dist / springs[i].getLength()); Here we draw all springs but no the edge ones, remember that edge particles contain no mass if ( springs[i].joint->GetBodyA()->GetMass() != 0 || springs[i].joint->GetBodyB()->GetMass() != 0 ) { Change colour ofSetColor( 255 * (colR * k), 255 * (colG * k), 255 * (colB * k) ); springs[i].draw(); } } -- Building UI The UI is built upon basic UIKit example bundled with openFrameworks. Additional views are created physicsView, meshView and infoView which are the pop-ups you see when clicked on buttons. The app variables such as adjustSpringDamping, adjustSpringFrequency, adjustForceRadius are connected to sliders. Likewise, their values are updated by init() (example: guiViewController.springDampingSlider.value = drag;). One all the dots were connected, adding a random button was easy by simply void testApp::runRandom() which randomises those values. Saving settings was done using ofxXmlSettings where slider values and switches are written to the xml file. When the app opens, the XML is read and values mapped to setup(). -- Addons used • MSAShape3D - by Memo Atken • ofxBox2d - box2d wrapper for OF by Tod Vanderlin • ofxXmlSettings -- About Ricardo Sanchez: Ricardo Sanchez a computer graphics enthusiast, originally from Maracaibo, Venezuela now residing in Bournemouth, UK.

• Flowerium [iPhone, iPad, openFrameworks] "Flowerium" is an iPhone/iPad application that observes the grow of digital plants. The seed is sown when you touch the screen, it falls on the ground and the new bud is born. The flowers bloom when they grow and you can preserve your favourites in your own flower library. It becomes a seed when there is a sufficient nutrition when the flower is in blossom. The seed has succeeded parents' genes. It hybridizes and it is inherited ..both characters.. when other plant flower is in blossom. The mutation might sometimes occur, and a change different from usual hybridization be done.

• Shot Shot Shoot [iPad, Games, oF] Shot Shot Shoot is the latest offering from Erik Svedang, the name behind Kometen we already mentioned on CAN. Shot Shot Shoot represents (Erik writes) a new way of playing games with your friends, combining the magic of computers with the special interactions made possible by board games. The goal of the game is simple: destroy the five squares on the opponent’s side of the board. Manoeuvre single shots with high precision or overwhelm the other player with massive attack waves. Go to the Shot Shot Guide if you want to know more about the rules of the game, strategy tips, etc. Made with openFrameworks, using CFXR (the Mac port of SFXR) for sound effects. Here is what our own Andreas Zecher says about the game: "If you have an iPad, a friend and $0.99, you need to get Shot Shot Shoot right now!" The game is currently on sale for a limited time — only $0.99! Sounds like a must. Platform: iPad Version: 1.0 Cost: $0.99 (limited time) Developer: Erik […]
• The Pirata Boat Race [iPhone, Flash, Games] The Pirata Boat Race pits two teams against one another to row themselves to victory. With up to ten shipmates split between two vessels, the aim is to propel your boat to the finish line before the other team, using your iPhone as your oars. The experience is much closer to console gaming than usually found online. The site itself acts as a hub, allowing multiple people to huddle around the screen, snap the QR code on their iPhones and propel their boat via the built-in accelerometer. To play the Boat Race head on over to piratalondon.com/boatrace and download the free app from the App Store. (Thanks Pieter) Platform: iPhone Version: 1.0 Cost: Free Developer: Pirata London […]
• Halcyon [iPad, Games, oF] – Preview Created by Zach Gage, Halcyon is the new iPad game from the creator of synthPond, Sonic Wire Sculptor, Lose/Lose, Bit Pilot and Unify, games and apps we loved on CAN. Halcyon is the result of months of Zach trying to figure out what would make a good iPad game. Although it took a lot longer than expected, Zach says it was about getting used to what the iPad was as an object, and how it was comfortable to use. I asked Zach few questions about his new game: FV: What was the inspiration behind Halcyon? ZG: One way to look at Halcyon is that it's what Unify would be if it had been developed for the iPad instead of the iPhone. Unify looked at what could be done in a casual puzzle game with multitouch, and that resulted in managing two pieces at the same time. Halcyon builds on that and says, "okay, we have a much larger screen now, what if instead of managing two pieces, we manage and entire system of possibly more than 100 pieces?". FV: How did you achieving this? ZG: I borrowed management systems of drawing lines like in Flight Control, but reduced them to the simplicity of control in a game like Tetris. In Flight control you have to manage pixel perfect collisions, meaning a plane can be in hundreds of thousands of unique positions. Tetris (and other similar puzzle games) work so well because a piece can be in one of only a few unique positions on one axis. In Halcyon pieces can only be in up to 9 positions on the vertical axis, so instead of making dozens of tiny tweaks to individual objects, the player has to make one tweak to dozens of objects. This puts the emphasis on understanding the system as a whole. FV: How would you describe the game? ZG: You take on the role of the Halcyon- a greek mythological bird that calmed the wind and seas during the winter solstice. You play as a conductor, untangling and calming systems of currents. To make this work, I decided that I wanted the game field to be extremely minimal and function as both a stringed instrument and a playing field. This meant removing any heads up display entirely (although there is one in the screens below because it's endless mode, there isn't one in the normal game). FV: You also refer to it "as a marriage of a generative musical instrument and a game"? ZG: As you play the game (or if you watch the video), all of the sounds are generated based on a chord. Each string has notes that relate to that chord and are strummed whenever you touch or when a piece moves up or down them. The background music is generated based on that chord whenever new pieces appear in the playing field (this is why the music speeds up or slows down when the field gets heavier or lighter with pieces). Additionally, as you start to do worse and pieces get closer to collisions, the chord shifts to a minor version of that chord, and than and even more minor one, subtlety changing the entire system and all the notes you are playing. This constant shift and unshift creates a very dynamic soundscape. FV: Tell us a little about the levels, modes, etc.. ZG: Halcyon will have 36 levels when I release it, along with two endless modes (Aggression and Harmony). These endless modes are very different than the ones in Unify or other puzzle games though. Aggression and Harmony are named for the type of AI that governs the experience. In both, the AI watches how you behave in the game and judges your skill level. In Aggression, the AI makes the game increasingly more difficult, attempting to push you to a place out of your skill level where you will lose. In Harmony, the AI attempts to keep you engaged by incrementing the difficulty, but also tries very hard to keep you from losing. Thanks Zach. The game has been submitted to this years IGF and we hope available in the AppStore soon is now available in the AppStore.
