  1. ok, got it, i report when i implemented it, thanks
  2. I hava a 3d map consisting out of triangles and player with a collision sphere. it looks a bit like this: http://ika.wdfiles.com/local--files/terrain-generation/Terrain.png I've Managed to reslove collisions with just one triangle. But i don't get it to resolve with multple objects, the sphere sinks in the floor time to time when i just resolve every MTV. So how can i make it right?
  3. Collision with polygon or Polyeder

    you mean even the player as a bunch of triangles?
  4. There's something i don't understand about collision: When i want to detect a collision between a polyeder (obstacle) and a sphere(Player), do i have to check collision between the Sphere and the polyeder(Sep. Axis th. 3d) or between the sphere and every face of the polyeder?
  5. ok, thanks, that helps me a lot
  6. ok the code should look like this -loop objects and flag if behind the player. -sort the objects, ignore the flaged ones. -check for collision on each face of each object, break if collision with face. -save face normal,bulletpositiono. -draw the bullet hole. is this right?
  7. ok so should check and loop all faces of all thetrahedrons, and not check all thetrahedrons first? wouldn't it save processor time by checking all thetrahedrons first, or did i missunerstand something?
  8. i think the title explains it pretty good: i want to make a function that takes the player position(start of the bullet path,vector)and the bullets direction, loops through all the Objects(thetrahedrons) and returns the Vectors Position and angle of the BUllet decal. although I have a fairly understanding of 3D geometry, i Have no Idea how i should solve it, expecialy the position in the thetrahedral.
  9. sorry, a friend has just told me, so it has done itself.
  10. no I ve got another Problem with the same Project: I made a little map format to create a map with a text editor and an interpreter for it. but haw can i dynamicly add new Objects to the level?
  11. thank you both, but i think Aardvajk, is right, i'll have to make an extra array
  12. sorry but i don't get the pointer cast, can you show me how I workds with pointers?
  13. To describe my Problem I have to expand a little: I wrote a game all of whose Objects(Timers,Inventory-Itemens, Walls, Trees...) are classes based on a subclass calleg gobject. The classes which are direct in the world(Trees, Players, Walls) are also based on a class called wobject which is based on gobject. always when an Object is created it gets automaticly added to a huge array of gobject pointers. The trick here is, that that even the most unimportant object has a virtual handle function, which is called on a big loop, that calls every handle for each pointer in the array. For example if the Player has an Item in his inventory, that automaticly heals him, I can write this in the virtual function of the class autopotion. but the Problem is, for example in the collision detection, I have to acess Attributes like height, width and position. How can I acess this attributes form the Pointer-Array?
  14. Resolve Collision

    Ok I finally figured out how to use SAT 3d But how can i resolve the collision. I first wantet to just reset the last step at a collision, but that seams unnatural. Does anyone have a better Idea?
