- Back to MLPV2_Addons
- MLPV2
Basically this is an alternative way of adding particle chain support to MLP2 using the LockGuard protocol. When the object is rezzed in world the script makes a list of the prim names and keys for later. It then reads the note card with the linking information each time inventory changes. When MLP2 gives pose info the script determines if it pertains to it's list and if so notifies lockguard enabled attachments of what to do and what prim keys to do it to.
Ed: Note that this script requires a build which has linked, at the point when the script starts up, the prim points (e.g. posts, etc) to which the chains from the person's cuffs etc will attach themselves.
So what do you need to do?
Step 1: Figure out what prims you want to use as anchor points, and give each a unique name. Personally I recommend the boring yet easy to remember format of point1, point2, point3, etc. Remember these names for later.
Step 2: Add the following script to your furniture. It may complain, but you can ignore that for now.

// ---------------------------------------------------------------------------------- // Changes: // ---------------------------------------------------------------------------------- // Version 1.3 // - Fixed an error that was causing multiple avatar chain sets from working // - Fixed chainData not properly clearing on a reload // - Changed the order of operations in the changed state for better tracking and simplified // // Version 1.2 // - Large overhaul of how the data on the cards is stored. Original format was made // to preserve the working of the MLP2 swap function. However no one ever uses the // swap function in a chained context, so why complicate the notecard files? Plus // new format is more memory friendly. // - Note card separator changed from ; to | to match favorite RLV plugin format // - Changed the need for the animation name to just the ball number in the note card // - Removed some unused variables // - Note card renamed to .CHAINDATA to follow MLP2 naming conventions // - Removed sim ratings data poll. // - Added warning if the desired target point does not exist in the linkset // - Added more comments because comments are good. // // Version 1.1 // - Added a data reload on inventory change // // Version 1.0 // - Changed script name from ~chaincontrol // - Cleaned up old comments and made it more readable // - First post to lsl wiki ( https://wiki.secondlife.com/wiki/MLPV2_Addons )
