Locking Cameras

[shadowmapper]

Basically I need to lock custom cameras, so that the player cannot adjust the camera at all. The camera is generally locked to a fixed unit (invisible dummy unit). Right now I'm using a trigger which executes every .5 seconds of the game and applies the camera and locks it to the dummy unit if the player has entered a region with a locked camera (say, a building interiors).

The cameras and their unit focuses are declared as global variables during initialization (camera array, unit array) and when the unit enters the a region with a locked camera, a Boolean variable (array) is set to true, meeting the 'if' statement conditions for whatever integer in the array the region corresponds too, and then setting the corresponding camera and unit to be locked.

To clarify, I don't want to just limit the field of view, I want to prevent the user from zooming in or out with the mouse wheel, basically from adjusting the camera at all.

Locking the camera to the player's main unit is also not an option here for various reasons.

The trigger is GUI generated and seems to be working fine, just wondering if there is a better way to do this, as executing the trigger every .5 seconds of the game may cause memory issues on other systems, I really don't know. Any comment on this would be appreciated too.

Try this:

//TESH.scrollpos=0
//TESH.alwaysfold=0
scope Camlock initializer InitTrig

globals
    //trigger CamLock
    integer INDEX = 0
    boolean array DEAD
    unit array HERO
    player array PLAYERS
    integer array IND
    //location LOC
endglobals

//private function Actions takes nothing returns nothing
//local integer index = 0
//local real x
//local real y
//local real z

//loop
    //exitwhen index == INDEX
    //set x = GetUnitX(HERO[index])
    //set y = GetUnitY(HERO[index])
    //call MoveLocation(LOC,x,y)

    //if GetLocalPlayer() == PLAYERS[index] then
        //if udg_Inventory_Player_Is_Viewing[index] == false then

            //if DEAD[index] == false then
            //set z = GetCameraField(CAMERA_FIELD_ZOFFSET)+300 - (256- GetLocationZ(LOC))-GetCameraTargetPositionZ()
            //call SetCameraField(CAMERA_FIELD_ZOFFSET,z,1.0)
            //call SetCameraPosition(x,y)
            //call SetCameraField(CAMERA_FIELD_TARGET_DISTANCE,1850,0.1)
            //call SetCameraField(CAMERA_FIELD_ANGLE_OF_ATTACK,315,0.1)
            //call SetCameraField(CAMERA_FIELD_ROTATION,140,0.1)

            //endif
        //endif
    //endif
    //set index = index + 1
//endloop
//endfunction

private function InitTrig takes nothing returns nothing
    //set CamLock = CreateTrigger()
    //set LOC = Location(0,0)
    set DEAD[0] = false
    set DEAD[1] = false
    set DEAD[2] = false
    set DEAD[3] = false
    set DEAD[4] = false
    set DEAD[5] = false
//call TriggerRegisterTimerEvent(CamLock,0.2,true)
//call TriggerAddAction(CamLock, function Actions)
endfunction


endscope

Thanks for the reply. Unfortunately I think that code is a little over my head... will I be able to set different camera attributes (i.e. target distance, angle of attack, rotation) for respective locations? If so it looks like I could at least take the stats off my cameras and then apply them to the script... but as I said, it's too advanced for me at the moment, but it's good study material xD

FYI Here's the GUI script I'm using now...

• CAMERA LOCK
  • Events
    • Time - Every 0.05 seconds of game time
  • Conditions
  • Actions
    • For each (Integer A) from 1 to 10, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • CAMERA_Locked[(Integer A)] Equal to True
          • Then - Actions
            • Camera - Apply CAMERA_LockedCameras[(Integer A)] for Player 1 (Red) over 0.00 seconds
            • Camera - Lock camera target for Player 1 (Red) to CAMERA_FocusPoints[(Integer A)], offset by (0.00, 0.00) using Default rotation
          • Else - Actions
            • Do nothing

As I said CAMERA_LockedCameras and CAMERA_FocusPoints are set at initialization, although I'm thinking now I could just set/change them just before CAMERA_Locked is set to True, which is usually when a unit enters a region, eliminating the loop.
