GetCameraPos

llGetCameraPos

Summary

Function: vector llGetCameraPos( );

0.0	Forced Delay
10.0	Energy

Returns a vector that is the current camera position for the agent the task has permissions for.

To run this function the script must request the PERMISSION_TRACK_CAMERA permission with llRequestPermissions.

Caveats

Permissions

Do not depend upon the auto-grant status of permissions. Always use the run_time_permissions event. If the script lacks the permission PERMISSION_TRACK_CAMERA, the script will shout an error on DEBUG_CHANNEL and the operation fails (but the script continues to run). Once the PERMISSION_TRACK_CAMERA permission is granted there is no way to revoke it except from inside the script (for example, with a new llRequestPermissions call) or the script is reset or deleted.

• Seems to act weird when the camera gets too far from the agent.

Examples

//Camera Follower Script
//llGetCameraPos & llGetCameraRot Example
//By Nika Rugani

integer perm_track = 0x400;
float second_check = 0.1;

vector object_offset = <2,0,0>; //Offset of the cameras position where the object will set itself

integer die_channel = 0;
string die_command = "/die";

quickPosRot(vector pos, rotation rot)
{//This way you don't have the 0.2 second sleeps from llSetPos and llSetRot
    llSetLinkPrimitiveParamsFast(LINK_THIS, [PRIM_POSITION, pos, PRIM_ROTATION, rot]);
}

default
{
    on_rez(integer a)
    {
        llResetScript();
    }
    state_entry()
    {
        llRequestPermissions(llGetOwner(), perm_track);
    }
    run_time_permissions(integer permission)
    {
        if(permission == perm_track)
        {
            llSetTimerEvent(second_check);
            llListen(die_channel, "", llGetOwner(), "");
        }
        else
        {
            //llResetScript(); //Remove comment to loop the process of requesting permissions if user deny's permission
            //llDie(); //Remove comment to kill the object if user deny's it
        }
    }
    listen(integer channel, string name, key id, string str)
    {
        str = llToLower(str);
        if(str == die_command)
        {
            llDie();
        }
    }
    timer()
    {
        vector c_pos = llGetCameraPos(); //Get Users Camera Position
        rotation c_rot = llGetCameraRot(); //Get Users Camera Rotation
        c_pos = (c_pos+object_offset*c_rot); //Apply the offset to the position
        quickPosRot(c_pos, c_rot); //EXECUTE ORDER!
    }
