// :DESCRIPTION:
// ZHAO=II compatible AO using the new LSL Animation functions, timer is now used only to detect swimming
// :CODE:
// As an exercise, I took a version of ZHAO II core and rewrote it to be compatible with a linked message interface, but used the new functions;
// It still needs to poll for swimming but I figured that could be done at a much slower rate than normally used in an AO.
// I had to forgo the ability to replace the typing anim since that would require a faster timer.
//  The new animation override functions don't allow for stacking anims in the way you used to with the , separator so that was given up.
// Finally, in the interests of cramming the core into a single 16k LSL compiled script I didn't implement the timing option for the different anims;
// it could certainly be done, I just chose not to do so!

// Evie Moriguchi/Edie Shoreland, 10/05/15 - Allow (but ignore) any [ Typing ] animations
//                   included in notecards without the script sending an error message.
//                   [No need to edit the "Default" notecard, Making it easier to dump ZHAO
//                   contents from an older ZHAO into a bot friendly single prim style AO.
//                   Put all animations (including the typing ones), this script, and the
//                   unedited "Default" notecard into a prim and reset the script.]
//                   Fixed so sitOverride == FALSE actually turns off the sitting override
//                   [Sit Override OFF is just the better option for bots and NPCs, no more
//                   weird glitchy sits while two priority 3 animations fight it out.]
//
// Chloe1982 Constantine, 05/08/13 - Modified/Updated to use the new LSL Animation functions, timer is
//                   now used only to detect swimming (timerEventLength)
//
// Ziggy, 07/16/07 - Warning instead of error on 'no animation in inventory', that way SL's built-in
//                   anims can be used
//
// Ziggy, 07/14/07 - 2 bug fixes. Listens aren't being reset on owner change, and a typo in the
//                   ground sit animation code
//
// Ziggy, 06/07:
//          Reduce script count, since idle scripts take up scheduler time
//          Tokenize notecard reader, to simplify notecard setup
//          Remove scripted texture changes, to simplify customization by animation sellers

// Fennec Wind, January 18th, 2007:
//          Changed Walk/Sit/Ground Sit dialogs to show animation name (or partial name if too long)
//          and only show buttons for non-blank entries.
//          Fixed minor bug in the state_entry, ground sits were not being initialized.
//
//
// Dzonatas Sol, 09/06: Fixed forward walk override (same as previous backward walk fix).

// New notecard format
//
/////////////////////////////////////////////////////////////////////////////////////////////////////
// Lines starting with a / are treated as comments and ignored. Blank lines are ignored. Valid lines
// look like this:
//
// [ Walking ]SexyWalk1|SexyWalk2|SexyWalk3
//
// The token (in this case, [ Walking ]) identifies the animation to be overridden. The rest is a
// list of animations, separated by the '|' (pipe) character. You can specify multiple animations
// for Stands, Walks, Sits, and GroundSits. Multiple animations on any other line will be ignored.
// You can have up to 12 animations each for Walks, Sits and GroundSits. There is no hard limit
// on the number of stands, but adding too many stands will make the script run out of memory and
// crash, so be careful. You can repeat tokens, so you can split the Stands up across multiple lines.
// Use the [ Standing ] token in each line, and the script will add the animation lists together.
//
// Advanced: Each 'animation name' can be a comma-separated list of animations, which will be played
// together. For example:
//
// [ Walking ]SexyWalk1UpperBody,SexyWalk1LowerBody|SexyWalk2|SexyWalk3
//
// Note the ',' between SexyWalk1UpperBody and SexyWalk1LowerBody - this tells ZHAO-II to treat these
// as a single 'animation' and play them together. The '|' between this 'animation' and SexyWalk2 tells
// ZHAO-II to treat SexyWalk2 and SexyWalk3 as separate walk animations. You can use this to layer
// animations on top of each other.
//
// Do not add any spaces around animation names!!!
//
// The token can be one of the following:
//
// [ Standing ]
// [ Walking ]
// [ Sitting ]
// [ Sitting On Ground ]
// [ Crouching ]
// [ Crouch Walking ]
// [ Landing ]
// [ Standing Up ]
// [ Falling ]
// [ Flying Down ]
// [ Flying Up ]
// [ Flying ]
// [ Flying Slow ]
// [ Hovering ]
// [ Jumping ]
// [ Pre Jumping ]
// [ Running ]
// [ Turning Right ]
// [ Turning Left ]
// [ Floating ]
// [ Swimming Forward ]
// [ Swimming Up ]
// [ Swimming Down ]
