  2. HUD-less Camera System
  3. by MP2
  4.  
  5. Set a player's camera WITHOUT THE HUD!
  6.  
  7. Version: 3.0 (3th of April 2013)
  8.  
  9.  
  10. HOW IT WORKS
  11.  
  12. There are 3 ways to set a camera:
  13.  
  14.     - Set (SetPlayerCamera)
  15.         • Set a player's camera instantly to a static location
  16.        
  17.     - Move (SetPlayerCamera: )
  18.         • Move (interpolate) a player's camera from it's current position to a new one
  19.        
  20.     - Interpolate (InterpolatePlayerCamera)
  21.         • Like Move but with a specified delay. Doesn't interpolate from current pos,
  22.         can interpolate from anywhere, TO anywhere.
  23.    
  24. To remove the HUD, the player is placed in to 'spectator mode'.
  25. When in spectator mode and not spectating a player/vehicle, the player will see
  26. a bridge, which I refer to as 'Spectator's Bridge'. If you set the player's camera
  27. straight away, it will not work; they will be staring at that brige.
  28. To get around this, you have to have a small delay. A timer would be your first thought
  29. (as it was mine) but I use OnPlayerUpdate (hooked) as if a player was paused when
  30. their camera was set, when they resume the game they will be still staring at
  31. Spectator's Bridge. This fixes that.
  32.  
  33. This include can be used for many things:
  34. - Login screens
  35. - Ban screens
  36. - Tutorials
  37. - 'CCTV' cameras
  38. - Menus
  39. - Cutscenes
  40. - and whatever else your imagination can think of!
  41.  
  42. If you have any suggestions, have found a bug (problem/issue) or just want to give some feedback
  43. (negative or positive, I'm always open to advice!)
  44. feel free to do so here: http://forum.sa-mp.com/showthread.php?p=2362690
  45.  
  46. Enjoy!
