  1. Thanks guys! @ Thekill473: I didn't call it free because on PlayBook the app is $1.99 upfront
  2. Hey guys, I'd like to present my newest app for iOS, Android, and PlayBook: Phyzicle - the 2D physics sandbox that can bring your imaginations to life! Use a variety of shapes, constraints, and even FLUIDS to build amazing contraptions! Instantly share your creations with friends and check out what others have made! iOS: Android: Playbook: http://appworld.blac...content/109011/ Facebook: Twitter: [media][/media] Simulation: - Infinite undo/redo - Multiple snapping options including snap-to-grid and snap-to-object-center - Tilt-based (accelerometer) gravity, zero gravity, and normal gravity - Complete customization of all objects, including bounciness, friction, density, collision groups, color, and more - On-screen action buttons to control motors and thrusters - Save, load, and upload your creations, and download others’ creations Fluids: - Complete interaction with rigid bodies - floating, sinking, pushing, and more - Multiple mixable colors Shapes: squares, rectangles, circles, gears, free-form convex/concave shapes Constraints: springs, rods, welding, pins (free or motorized), thrusters, sliders Phyzicle includes a comprehensive guide, multiple tutorials, and more! Found a bug? Want to request a feature? Have something to tell us? Visit the Contact section in the guide! We’re committed to our players and will do our best to fix every bug, implement every feature, and reply to all feedback! With a multitude of features and such loyal developers, Phyzicle is THE physics sandbox you want to be playing on your mobile device!
  3. Hm, that's odd. I don't really go on Gamedev too often anymore anyways, so feel free to shoot me an email at nullsquared at google's email (heh, avoiding spam) I'm not sure if this is directed towards me, but I just want to throw it out there that I rated Tom Sloper down for responding to such a detailed, intriguing post with a mere "Yes."
  4. Fellow Playbook developer here I'm not using their native SDK, though, I'm using Marmalade (so I can deploy to iOS/Android/Playbook at once). The App World is an interesting place, as people are desperate for good apps. I'm about to release an app called Phyzicle on the App World: It's gonna be $1.99 so we'll see how well it sells on the App World... Either way, I believe the $10,000 incentive is for BB10 (their smartphone platform), not Playbook OS.

    Crossmobs SDK

    Look interesting, albeit slightly sketchy like you mentioned. A similar SDK is Marmalade (clicky). It's a very professional, flexible, big-name SDK that allows you to deploy to iOS and Android (among many other platforms, like bada, webOS, Playbook, etc.) using C++.

    TreeD - 3D isometric pixel art editor

    That looks insanely cool!
  8. Viewing this from the perspective of an average user, I think it might be even more annoying than just having to register, haha - I certainly wouldn't want some random game asking me for my facebook username and password just so I can upload a custom level I made. Either way, thanks for the idea! That said, I think I'm just going to keep it IP-based. I know IPs change and such, but all I'm really looking for is "hey, you can't upload more than 1 level every N seconds/minutes". In order for someone to spam my server, they would have to constantly spoof their IP and their user-agent, in which case I can implement a global maximum-uploads-per day limit and simply delete the entire pending levels directory and ask users to reupload their genuine levels. I suppose having a UID generate per-game is useful in this case instead of using their IP.
  9. only problem with IPs is they aren't static for each machine. multiple machines behind the same router share an IP. computers can go from place to place using different IPs and a lot of ISPs provide dynamic IPs rather than static IPs. You could try using some type of uid system for tracking users rather than user registration. So the game would store locally a uid and if it doesn't have one it would ask the server for one, the server would then generate a new uid for the user that they can use to use the service. If they don't provide a valid uid for the system when using other services than uid generation you can lock them out. [/quote] Alright thanks a bunch for your input!
  10. Thanks for the help! I don't want to force users to register...I think I'm just going to use IPs combined with timeouts
  11. Hey, I'm working on a game that allows players to upload and download custom levels and replays. The uploading is done by connecting to my webpage and sending custom level/replay data to a PHP script, which then stores it on the server for review. Since I have to review all custom content, the end-users will never have an issue. However, *I* might have an issue with people uploading spam data by mimicking my game. How can I prevent people from mimicking my game and uploading a bunch of spam to fill my server?

    Faking 3rd dimension in 2D game

    Also, note that much of the "3D illusion" comes from the shadow of the ball. As the "height" of the ball increases, the shadow goes further from the ball in the direction of the light.

    UV coordinate on a 2D quadrilateral

    Thank you very, very much! This came out to be the easiest solution to implement and it works great! In case anyone is interested in the same problem, here's some code: double C = (double)(a.Y - p.Y) * (d.X - p.X) - (double)(a.X - p.X) * (d.Y - p.Y); double B = (double)(a.Y - p.Y) * (c.X - d.X) + (double)(b.Y - a.Y) * (d.X - p.X) - (double)(a.X - p.X) * (c.Y - d.Y) - (double)(b.X - a.X) * (d.Y - p.Y); double A = (double)(b.Y - a.Y) * (c.X - d.X) - (double)(b.X - a.X) * (c.Y - d.Y); double D = B * B - 4 * A * C; double u = (-B - Math.Sqrt(D)) / (2 * A); double p1x = a.X + (b.X - a.X) * u; double p2x = d.X + (c.X - d.X) * u; double px = p.X; double v = (px - p1x) / (p2x - p1x); u and v are then [0,1] coordinates you can sample a texture from, etc. Thanks again!

    UV coordinate on a 2D quadrilateral

    Hm, you're right. Any other ideas? I'm basically trying to map out a virtual 2D quadrilateral onto a physical, rectangular screen. (Basically, texture mapping it.)

    UV coordinate on a 2D quadrilateral

    Ok, cool, thanks for the information. I'll try it If anyone has any other ideas, feel free to chip in.
