• How does one block unsupported web browsers?

  - by Sn3akyP3t3

  Web browsers with an end of life no longer receive security updates which not only makes them vulnerable to the end user, but I imagine its not safe for the server's which receive visits by them either. Is it practical to block or enforce and notify the end user that their browser is unsafe and unsupported? If so, how would one achieve that? I…

• Pixel perfect collision with paths (Android)

  - by keysersoze

  Hi I'm writing a game and I'm trying to do some pixel perfect collisions with paths. The player's character has a bitmask which looks for example like this: Currenly my code that handles player's collision with path looks like this: private boolean isTerrainCollisionDetected() { if(collisionRegion.op(player.getBounds(),…

• Trouble with AABB collision response and physics

  - by WCM

  I have been racking my brain trying to figure out a problem I am having with physics and basic AABB collision response. I am fairly close as the physics are mostly right. Gravity feels good and movement is solid. The issue I am running into is that when I land on the test block in my project, I can jump off of it most of the time. If…

• How are trajectories calculated and transmitted to other players in Multi-Player ?

  - by giulio

  I play alot of COD4. And can see tracers for gunfire, missles, care packages fall from helicopters etc. There is alot of activity. I am curious to know the algorithm (at a high level) that manages all this action when you have 20 people on a map shooting each other to death ? This question touches on the subject but doesn't ask…

• most efficient AABB vs Ray collision algorithms

  - by Asher Einhorn

  Is there a known 'most efficient' algorithm for AABB vs Ray collision detection? I recently stumbled accross Arvo's AABB vs Sphere collision algorithm, and I am wondering if there is a similarly noteworthy algorithm for this. One must have condition for this algorithm is that I need to have the option of querying the result for…

• Circle physics and collision using vectors

  - by Joe Hearty

  This is a problem I've been having, When making a set number of filled circles at random locations on a JPanel and applying a gravity (a negative change in the y), each of the circles collide. I want them to have collision detection and push in the opposite direction using vectors but I don't know how to apply that to my scenario…

• How to avoid circular dependencies between Player and World?

  - by futlib

  I'm working on a 2D game where you can move up, down, left and right. I have essentially two game logic objects: Player: Has a position relative to the world World: Draws the map and the player So far, World depends on Player (i.e. has a reference to it), needing its position to figure out where to draw the player character,…

• Detailed Modern Opengl Tutorial?

  - by Kogesho

  I am asking for a specific modern opengl tutorial. I need a tutorial that does not skip to explain any lines of code. It should also include different independent objects moving/rotating (most tutorials use only one object), as well as imported 3d objects and collision detection for them. It should also avoid stuff that won't…

• How should I choose quadtree depth?

  - by Evpok

  I'm using a quadtree to prune collision detection pairs in a 2d world. How should I choose to what depth said quadtree is calculated? The world is made mostly of moving objects1, so the cost of dispatching the objects between the quadtree cells matters. What is the relationship between the gain from less collision checking and…

• Detecting pixels in a rotated Texture2D in XNA?

  - by PugWrath

  I know things similar to this have been posted, but I'm still trying to find a good solution... I'm drawing Texture2D objects on the ground in my game, and for Mouse-Over or targeting methods, I'm detecting whether or not the pixel in that Texture at the mouse position is Color.Transparent. This works perfectly when I do not…

• How to determine collision direction between two rectangles?

  - by Jon

  I am trying to figure out how to determine the direction a collision occurs between two rectangles. One rectangle does not move. The other rectangle has a velocity in any direction. When a collision occurs, I want to be able to set the position of the moving rectangle to the point of impact. I seem to be stuck in…

• Collision representation in game overworlds

  - by Akroy

  I'm implementing a 2D overworld where one can walk through an area that is not tile based. I was wondering the best way to implement collisions. In the past when I've done similar things, I've used one image (or set of images) to show an elaborately drawn world and then a second binary image that does nothing but…

• XNA 2D Rotated Rectangle Collision Response

  - by Kyle Uithoven

  I am using Rotated Rectangles which collide using the Separating Axis Theorem and they work perfectly fine for collision detection using Intersects and Contains. However, I am starting to use faster objects in my game now and there is the issue of the two object overlapping during collision due to their higher…

• Edge Detection on Screen

  - by user2056745

  I have a edge collision problem with a simple game that i am developing. Its about throwing a coin across the screen. I am using the code below to detect edge collisions so i can make the coin bounce from the edges of the screen. Everything works as i want except one case. When the coin hits left edge and…

  [I originally posted on SO but it earned me a Tumbleweed badge. This looks like a better venue for the question.] I have Apache (XAMPP 1.8.0) running on Vista Pro x64. A couple times now I have seen a pattern like the example below in access.log. Concerning is the "attack" seems to somehow shift from a…

• Collision detection when pathfinding with pathnodes, UDK

  - by Dave Voyles

  I'm trying to create a class that allows my AIController to path find using pathnodes (NOT NavMeshes). It's doing a swell job of going from point to point in a set order (although I would like for it to be a random patrol at some point), but it gets caught up on collision from time to time. I.E. He'll…

• Performance issues with visibility detection and object transparency

  - by maul

  I'm working on a 3d game that has a view similar to classic isometric games (diablo, etc.). One of the things I'm trying to implement is the effect of turning walls transparent when the player walks behind them. By itself this is not a huge issue, but I'm having trouble determining which walls should…

• Object detection in bitmap JavaScript canvas

  - by fallenAngel

  I want to detect clicks on canvas elements which are drawn using paths. So far I have stored element paths in a JavaScript data structure and then check the coordinates of hits which match the element's coordinates. Rendering each element path and checking the hits would be inefficient when there…

• Mobile phone detection (brand, model, browser etc)

  What do you use to detect visitor's mobile phone, down to the model if possible? Currently we maintain our own database but it's really getting behind due to lack of manpower to maintain it, so we decided to give 3rd party solution a try. These are my candidates but I don't have time to really…
