Live Features

• Thread Control
  • %threadid%
    • Returns the current ID of a thread, which is a record with the following fields:
      • entity: a reference to the thing the thread is running on
      • thread: an id number for a thread unique to the entity
  • killthread
    • Stops the specified script thread
• 64 bit
  • The script engine now uses 64 bit math; this allows for a MUCH greater range of numbers ( > 2 billion, < -2 billion) and more accuracy in decimal math
• New xor logic
  • A ^^ B
  • "true" if either A or B is true, but not if both are true
• Bitwise logic
  • New bitwise operators &, |, ^, <<, >>
  • "val1 & val2" returns an intersection of the bits of val1 and val2 (only the bits that are set in both values)
  • "val1 | val2" returns a union of the bits of val1 and val2 (a combination of all set bits in both balues)
  • "val1 ^ val2" returns an exclusive union of the bits of val1 and val2 (only the bits that are set in either value but not both)
  • "val1 << val2" shifts the bits of val1 left by val2 bits
  • "val1 >> val2" shifts the bits of val1 right by val2 bits
  • ~ unary operator (~value) inverts the bits of the value
• Allowing ~ as a character in all editable text
• Filters
  • %var.filter(FILTER SPEC)%
  • A list may be filtered as a series of values, objects, or records, with a comparison to another value. Anything not matching the filter is discarded.
  • Example: %self.room.people.filter("race == Alien")%
  • This would return a list of characters in the room that are Aliens
• Threading a function onto an object
  • thread <target> Function(args)
  • A function in a script may be 'threaded' onto another object, that is, a new script is created on the target object, and it starts executing the function. When the function ends or halts, the script disappears. This is similiar to attaching a script to an object and then 'calling' that script, without the need to create a second script.
  • Functions in imported scripts can be threaded onto an object as well
• Function arguments
  • Now a function definition can include the list of variables to fill in based on the comma-separated arguments passed to it:
  • function Func(var1, var2, var3)
  • calling Func like: %Func(foo, bar, baz 45)% will fill in the variables as such:
    • var1 = foo
    • var2 = bar
    • var3 = baz 45
    • arg is NOT set, any excess parameters passed would be ignored
  • A function with no ( ) in it's definition will still get %arg%
  • A function with ( ) but no variables in the list will NOT get %arg%, it will not get any variables set
  • No variable name, like: function Func(var1, , var3) will work, with the middle paramter ignored (that is, the results will be the same as above; var1 = foo, var3 = baz 45, var2 will not exist)
• Constant Data
  • constant <varname> <value>
  • Just like a variable! However, it cannot be set. If you do set it, you are merely creating a new local/global that overrides it.
  • Accessible like a function, within the current script (including functions), and anything in the script that imports it
• %players% - returns a list of all live connected sockets
• clan() returns a record of clan data
  • Returns list of allies
• Hexadecimal and octal numbers supported through most of the script engine
• room.newexit(dir) returns the new-format exit data
• value.paramfind(match) finds a matching parameter
• object.gun returns an object's gun data as a record
• character.bonusarmor returns bonus armor of a character
• send, echo, echoaround, echoaround2 can take optional +sleeping argument to also send to sleeping characters
• inc/increment and dec/decrement variable commands added
• endcombat renamed stopcombat
• Behavior Sets
  • A "Set" of scripts and predefined variables that an object/mob/room can inherit from, without having to manually set the scripts/variables on the object. When the set is modified, all of the objects that use that set will be updated properly.
• oset command to alter object variables
• text.splat(num) - given the text string, repeat it num times.
  • Example: %foo.splat(3)% - repeats contents of %foo% 3 times. %string("BLAM!").splat(4)% produces "BLAM!BLAM!BLAM!BLAM!"
• list.intersection(list2) - given list and list2, produces a list of words that are common to both
• mob kill trigger - functions like obj kill trigger, triggers whenever the mob kills something

Planned

• Specifically saved variables
  • SAVE-VARIABLES flag will go away, and only variables that are marked as saving, will save
• Persistent Data storage/retrieval
