llSetSunDirection

	LSL Feature Request
	The described function does not exist. This article is a feature request.

Summary

Function: llSetSunDirection( vector direction, float Delay );

	Forced Delay
	Energy

Requests the UserAgent's Viewer to change the phase of day/night to a specific Direction while sitting on the object containing the script. (This function prototype assumes that the parameter specifying the SunDirection would be a vector, which is probably wrong, as Windlight appears to control this with a float which is the Arc of the Sun.) The transition should take the number of seconds specified by the Delay parameter. llSetSunDirection recognizes 5 preset vectors that function similar to the Menu choice World->Force Sun

A related JIRA feature request exists at VWR-7677. Please go vote for it if this is important to you.

• vector	direction	–	A vector that is the direction of the sun in the region
• float	Delay	–	Seconds to allow for the change

Constants		Action
SUNRISE	<?,?,?>	Sets the Direction to the East.
NOON	<?,?,?>	Sets the Direction to up.
SUNSET	<?,?,?>	Sets the Direction to the West.
MIDNIGHT	<?,?,?>	Sets the Direction to down.
REGION_DEFAULT	<?,?,?>	Sets the Direction to the region's current Direction.

Examples

Notes

Useful for nightclubs and space oriented sims, which will prefer night environments. Also for items such as sailboats that tend to prefer day. This function applies to an avatar who is currently seated on a prim with a script that makes this call, much as llForceMouselook is able to implicitly get permission to change the viewer state. This might suggest a likely permission (i.e. PERMISSION_CONTROL_ENVIRONMENT) that could be requested of the avatar: llRequestPermissions( AvatarKey, PERMISSION_CONTROL_ENVIRONMENT ) and detected when granted, by the event: run_time_permissions(integer perm) by testing the permission value against the appropriate constant if(perm & PERMISSION_CONTROL_ENVIRONMENT). Alternatively, this function might have the Avatar Key passed as a parameter. Which could remove the implicit permission that the SIT action would grant.

Functions

•	llGetSunDirection	–	Setting the Direction, then waiting the Delay period, and calling llGetSunDirection should return the vector specified in the original llSetSunPosition.
•	llForceMouselook	–	Suggests that this type of request is reasonable to send to a User Agent/Viewer.
•	llAvatarOnSitTarget	–	Call this to determine what agent would be affected by this call.
