These expressions can set and retrieve variables, react to object/char properties, use and combine objects, and more.
This adds the "Expression" meta condition and the "Expression Action" and "Chat Expression" meta actions.
The "/vt mexec [expression]" command can be used instead of the meta rules when appropriate. It is also a great testing tool.
There are two ways to use Expressions, your situation will determine the best choice.
The first is through sending the command like any other chat command. Ex: "/vt mexec [expression]". This can be useful if you want to issue the command without using a meta rule, or simply want to test an expression without using meta.
The second is by utilizing the "Expression" meta condition and the "Expression Action" and "Chat Expression" meta actions.
The "Expression" meta condition is like any other meta condition, if the parameters are met then it will initiate the action. You can use this to detect world objects, character properties, react to custom variables and more.
The "Expression Action" meta action initiates the expression written within.
The "Expression Chat" meta action is used to output expression strings to chat. You can use regex and meta functions to format an expression. When outputting numbers from a variable you must first convert it to a string.
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.
