Emblem-important-red.png Pre-release Documentation Warning!

This function is not available yet. This documentation was written prior to its final release so it may not match the final implementation.

Summary

Function: integer llSetLinkMedia( integer link, integer face, list params );

Set the media params for a particular face on the linked prim(s) without a delay.
Returns an integer that is a STATUS_* flag which details the success/failure of the operation(s).

• integer link
• integer face face number
• list params a set of name/value pairs (in no particular order)

Success/Failure Flags Description
STATUS_OK 0 Result of function call was success
STATUS_MALFORMED_PARAMS 1000 Function was called with malformed parameters
STATUS_TYPE_MISMATCH 1001 Argument(s) passed to function had a type mismatch
STATUS_BOUNDS_ERROR 1002 Argument(s) passed to function had a bounds error
STATUS_NOT_FOUND 1003 Object or other item was not found
STATUS_NOT_SUPPORTED 1004 Feature not supported
STATUS_INTERNAL_ERROR 1999 An internal error occurred
STATUS_WHITELIST_FAILED 2001 Whitelist Failed
Parameter Additional Parameters Description
PRIM_MEDIA_ALT_IMAGE_ENABLE ] 0 [ integer boolean ] Sets the default image state (the image that the user sees before a piece of media is active) for the chosen face. The default image is specified by Second Life's server for that media type.

Note: This flag is not currently implemented.

PRIM_MEDIA_CONTROLS ] 1 [ integer control ] Sets the style of controls. Can be either PRIM_MEDIA_CONTROLS_STANDARD or PRIM_MEDIA_CONTROLS_MINI.
controls Flags Description
PRIM_MEDIA_CONTROLS_STANDARD 0 Standard web navigation controls.
PRIM_MEDIA_CONTROLS_MINI 1 Mini web navigation controls; does not include an address bar.
PRIM_MEDIA_CURRENT_URL ] 2 [ string current_url ] Sets the current url displayed on the chosen face. Changing this URL causes navigation. 1024 characters Max
PRIM_MEDIA_HOME_URL ] 3 [ string home_url ] Sets the home url for the chosen face. 1024 characters max
PRIM_MEDIA_AUTO_LOOP ] 4 [ integer boolean ] Sets whether auto-looping is enabled.
PRIM_MEDIA_AUTO_PLAY ] 5 [ integer boolean ] Sets whether the media auto-plays when a Resident can view it.
PRIM_MEDIA_AUTO_SCALE ] 6 [ integer boolean ] Sets whether auto-scaling is enabled. Auto-scaling forces the media to the full size of the texture.
PRIM_MEDIA_AUTO_ZOOM ] 7 [ integer boolean ] Sets whether clicking the media triggers auto-zoom and auto-focus on the media.
PRIM_MEDIA_FIRST_CLICK_INTERACT ] 8 [ integer boolean ] Sets whether the first click interaction is enabled.

Note: This flag appears not to work.

PRIM_MEDIA_WIDTH_PIXELS ] 9 [ integer width ] Sets the width of the media in pixels.
PRIM_MEDIA_HEIGHT_PIXELS ] 10 [ integer height ] Sets the height of the media in pixels.
PRIM_MEDIA_WHITELIST_ENABLE ] 11 [ integer boolean ] Sets whether navigation is restricted to URLs in PRIM_MEDIA_WHITELIST.
PRIM_MEDIA_WHITELIST ] 12 [ string CSV ] Sets the whitelist as a string of escaped, comma-separated URLs. This string can hold up to 64 URLs or 1024 characters, whichever comes first.
PRIM_MEDIA_PERMS_INTERACT ] 13 [ integer perms ] Sets the permissions mask that control who can interact with the object:
PRIM_MEDIA_PERMS_CONTROL ] 14 [ integer perms ] Sets the permissions mask that control who can see the media control bar above the object:

Caveats

  • The function silently fails if its face value indicates a face that does not exist.
  • If prim-media is not already on this object, add it.
  • Params not specified are unchanged, or if new media is added set to the default specified.
  • Both width and height must be specified together to work, and they narrow the texture space while inversely widening the aperture.
    • width and height scaled larger than 1024pixels will require the texture backdrop to be resized to fit(see Useful Snippets)
      • if resized to fit, the resulting view will cut off scrolled content outside the bounds making it impossible to be viewed
