FFHUD: a simple FriendFeed HUD

  • An idea by Opensource Obscure
  • Current release: 0.7.1
  • One-button, Custom messages, Rooms and Profile Image support

FFHUD lets you publish to the FriendFeed microblogging service from inside Second Life. Your posts will always include a SLURL link to your actual location. You can send a quick update that automatically includes the parcel description, or write a custom message. If available, the owner or owner-group profile image is also published, accordingly to their privacy settings.

FFHUD is an ideal way to participate on web social networks while you're enjoying Second Life. You can publish a quick review of an interesting place you just found in-world, or share with your friends your random thoughts from your home.

Setup

  • Put the script (see below) in a prim (you may also want to rename it).
  • Edit the script and insert your FriendFeed account data. You may also specify a room.
  • Wear the prim as an HUD. Resize and replace as needed.

How to use FFHUD

Touch it once to get information about the parcel you're in (printed in private chat via llOwnerSay). Then:

  • if you're not publishing a post, just wait until FFHUD resets itself before touching it again;
  • touch it again within 20 seconds to publish a post on FriendFeed that includes available info about the parcel: SLURL, description, owner profile image;
  • or say a message on channel 8 within 20 seconds to publish a post that includes both parcel info and your message. Example:
/8 This is my message

Do you need help? Feel free to contact me (Opensource Obscure) in-world, through this wiki or on FriendFeed.

Notes

FFHUD builds your posts this way:

  • LINK = SLURL of your location
  • TITLE = parcel name
  • COMMENT = parcel description (if available) OR your message
  • IMAGE = profile image of resident or group that owns the parcel
  • ROOM = according to your settings

FFHUD shows the FriendFeed logo by default. After you touch it once, it will display the parcel owner profile image, if available.

Profile images are shown by using llSetTexture; the UUID is retrieved using the Second Life Search; the image web address (not the image itself) is sent to FriendFeed, that then retrieves and hosts a copy of the image.

If you're on FriendFeed, you may want to join this room:

Script

This code works but may be horrible and flawed. Feel free to suggest me how to improve it. I am not a real developer and I lack some programming basis, so any feedback can help me. I usually make the LSL scripts I need by reading around, cutting, pasting and tweaking code from other sources. To write FFHUD I used snippets by User:Ordinal Malaprop, User:Cory Linden, MarcoDuff Palen, User:Jana Kamachi and others.

To do:

<lsl>// FFHUD 0.7 // free for public use // A project started by Opensource Obscure //

// Look for your username and FriendFeed key here: https://friendfeed.com/account/api string user=""; // your FriendFeed username string ffkey=""; // your FriendFeed key

// You can send messages to a FriendFeed room: // "" -----------> default setting - you won't share messages to any room // "ffhud" ------> a test room you can freely use // "secondlife" -> an unofficial SL room - http://friendfeed.com/rooms/secondlife // Change accordingly the line below: string room="";


// after 1st click you have a few seconds to write and send // your text message before FFHUD comes back to default state. // you can change the timing below: float listentime = 20.0;


/////////////////////////////////////////////////// // you don't need to modify anything below
