LSL Wiki : llSetCameraParams

llSetCameraParams(list rules)

Sets multiple camera parameters at once.
List format is [rule1, value1, rule2, value2 . . . ruleN, valueN]

Requires PERMISSION_CONTROL_CAMERA. The agent/avatar camera function targets the agent that gave PERMISSION_CONTROL_CAMERA to the script. (The UUID of which is returned by llGetPermissionsKey.)

For more information and example script see follow cam.

Rule	Value	Type	Default	Value Range	Description
`CAMERA_ACTIVE`	12	integer isActive	`FALSE`	`TRUE` or `FALSE`	Turns on or off scripted control of the camera.
`CAMERA_BEHINDNESS_ANGLE`	8	float degrees	10.0	0 to 180	Sets the angle in degrees within which the camera is not constrained by changes in target rotation.
`CAMERA_BEHINDNESS_LAG`	9	float seconds	0.0	0 to 3	Sets how strongly the camera is forced to stay behind the target if outside of behindness angle.
`CAMERA_DISTANCE`	7	float meters	3.0	0.5 to 10	Sets how far away the camera wants to be from its target.
`CAMERA_FOCUS`	17	vector position	n/a	n/a	Sets camera focus (target position) in region coordinates.
`CAMERA_FOCUS_LAG`	6	float seconds	0.1	0 to 3	How much the camera lags as it tries to aim towards the target.
`CAMERA_FOCUS_LOCKED`	22	integer isLocked	`FALSE`	`TRUE` or `FALSE`	Locks the camera focus so it will not move.
`CAMERA_FOCUS_OFFSET`	1	vector meters	<0.0, 0.0, 0.0>	<-10,-10,-10> to <10,10,10>	Adjusts the camera focus position relative to the target.
`CAMERA_FOCUS_THRESHOLD`	11	float meters	1.0	0 to 4	Sets the radius of a sphere around the camera's target position within which its focus is not affected by target motion.
`CAMERA_PITCH`	0	float degrees	0.0	-45 to 80	Adjusts the angular amount that the camera aims straight ahead vs. straight down, maintaining the same distance; analogous to 'incidence'.
`CAMERA_POSITION`	13	vector position	n/a	n/a	Sets camera position in region coordinates.
`CAMERA_POSITION_LAG`	5	float seconds	0.1	0 to 3	How much the camera lags as it tries to move towards its 'ideal' position.
`CAMERA_POSITION_LOCKED`	21	integer isLocked	`FALSE`	`TRUE` or `FALSE`	Locks the camera position so it will not move.
`CAMERA_POSITION_THRESHOLD`	10	float meters	1.0	0 to 4	Sets the radius of a sphere around the camera's ideal position within which it is not affected by target motion.

Example using default values:

llSetCameraParams([
        CAMERA_ACTIVE, 1, // 1 is active, 0 is inactive
        CAMERA_BEHINDNESS_ANGLE, 10.0, // (0 to 180) degrees
        CAMERA_BEHINDNESS_LAG, 0.0, // (0 to 3) seconds
        CAMERA_DISTANCE, 3.0, // ( 0.5 to 10) meters
        // CAMERA_FOCUS, <0,0,0>, // region-relative position
        CAMERA_FOCUS_LAG, 0.1 , // (0 to 3) seconds
        CAMERA_FOCUS_LOCKED, FALSE, // (TRUE or FALSE)
        CAMERA_FOCUS_THRESHOLD, 1.0, // (0 to 4) meters
        CAMERA_PITCH, 0.0, // (-45 to 80) degrees
        // CAMERA_POSITION, <0,0,0>, // region-relative position
        CAMERA_POSITION_LAG, 0.1, // (0 to 3) seconds
        CAMERA_POSITION_LOCKED, FALSE, // (TRUE or FALSE)
        CAMERA_POSITION_THRESHOLD, 1.0, // (0 to 4) meters
        CAMERA_FOCUS_OFFSET, ZERO_VECTOR // <-10,-10,-10> to <10,10,10> meters
    ]);

Q: How can you make the camera move smoothly from one CAMERA_POSITION to another? Or pan smoothly from one CAMERA_FOCUS to another?
A: Hmm thats a tough one. What you could do, is have a volume-detect prim as a vehical, then have the avatar sit on the vehical, next drop the camera at the static location. Make the box invisible and have the avatar underground (flip the box upside down). That may allow you to move the box, which should change the focus. If you made the camera follow instead, you could use that to change it's position. - BW

Q: It seems like the camera only moves into its position when the user touches a the Left or Right rotate key. Does this make any sense?
A: Sounds like an issue with one of the Threshold parameters - Anon
A: Could also be due to the fact that their camera isn't set into the default position (esc key) before sitting so by pressing the Left or Right arrow key sets it to the default position which is what's speicified by the script

Q: How would I have the camera follow the vehicle an avatar is sitting on even if the sit target is far away. Also, have the camera follow it smoothly, not reset everytime the vehicle moves?
A:
