SetAgentEnvironment

llSetAgentEnvironment

Summary

Function: llSetAgentEnvironment( key agent_id, float transition, list params );

	Forced Delay
	Energy

This function sets environment values for an individual agent in an experience. The changes to the environment persist until the agent moves to a new region or llSetAgentEnvironment is called for an agent with an empty list. Passing an empty list in params will strip all environmental settings applied to this agent as part of the experience

• key	agent_id	–	The key for an agent in the region. The agent must be in the region and must be participating in the experience.
• float	transition	–	The number of seconds over which to transition to the new settings.
• list	params	–	A list of parameters to retrieve from the current environment. See table below for details.

Return Values

Value	Constant	Description
	1	The agent has been instructed to change their environment.
ENV_NOT_EXPERIENCE	-1	The script is not running as part of an experience with a valid experience key.
ENV_NO_EXPERIENCE_PERMISSION	-2	The agent has not granted permission.
ENV_NO_ENVIRONMENT	-3	The environment inventory object could not be found.
ENV_INVALID_AGENT	-4	Unable to find specified agent.
ENV_INVALID_RULE	-5	There was an issue with one of the rules.
ENV_VALIDATION_FAIL	-6	Unable to validate values passed.
ENV_NO_EXPERIENCE_LAND	-7	The experience has not been enabled or can not run on the land.
ENV_THROTTLE	-8	The scripts have exceeded the throttle. Wait and retry the request.

Caveats

• The list of valid parameters differs from those available for llGetEnvironment.
• The agent's viewer may choose to ignore this command.
• An environment set locally on the viewer will override any environment set from this function.
