These expressions can set and retrieve variables, control chat output, and more.
This adds the "Expression" meta condition and the "Expression Action" and "Chat Expression" meta actions.
The "/vt mexec [expression]" command is used for testing these expressions
Notes
- true is the same as 1, false is the same as 0. There are no actual booleans, just numbers.
- There are two extra operators added since monster expressions: the ^ (xor) operator, and the ; operator. The ; operator works on any two types and simply returns the value of the first one. It has the lowest possible precedence. The idea is to use it to string together commands when you don't care about the result.
- Unlike monster expressions, meta expressions do not trim spaces from the ends of strings.
- Set variables persist until cleared by a command or until relog.
- Formatting during the conversion of number to string is a string like this: http://msdn.microsoft.com/en-us/library/kfsatb94%28v=vs.110%29.aspx
- All operator characters which occur in a string must be escaped with \
- All numbers in a string must also be escaped.
