MLPV2 LockGuard plugin
- Back to MLPV2_Addons
- MLPV2
Basically this is an alternate 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.
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.

Step 3: Create the data note card. This card needs to be named .chains, but can have a further name past that if you need to use more than one card. The card will look something like this:
////////////////////////////////////////////////// // Chain control ////////////////////////////////////////////////// // Part 1: menulable // Part 2: animation chain is linked to // Part 3: prim name to link to // Part 4: LG attach point // Part 4 optional commands: // texture key // size # # // life # // gravity # // speed # // color # # # ////////////////////////////////////////////////// Bound;Short Posts-1;point2;rightwrist gravity 0.2 life 0.75 Bound;Short Posts-1;point4;leftwrist gravity 0.2 life 0.75 Bound;Short Posts-1;point3;collarfrontloop gravity 1.75 life 1.5 Displayed;dungeon-2;point1;wrists gravity 0.0 life 2.0 Hung;dungeon-3;point1;wrists gravity 0.0 life 0.75 Dangled;Hung-2A;point1;ankles gravity 0.0 life 0.75 Captured;Why Me-v2;point3;wrists gravity 0.0 life 0.25
