addhook("say","_s")
function _s(id,t)
if t == "!off" then
bool = false
elseif t == "!on" then
bool = true
end
end
He didn't want to explain it but it's enough of an explanation. He wants to be able to control something by saying "on/off".

Dousea: Ooooh. I was aware of a similar method for writing an IF but not like how you did. You're incorporating an 'if' while assigning a value to 'boolean'. Daaam. I learned sth new today. Dousea has written1

That's still going over my head.
Wouldn't variable 'boolean' return the text instead of a true boolean value? How does this work?
Nekomata: well, he's comparing the message just like you do in an if. An if always returns either 'true' or 'false' values (not in text of course) and then he assigns the boolean to be the result of the if

boolean = message == "!on"
Either I'm missing out something really simple minded (I tend to do that) or I need to hit the basics of conditions.
Nevertheless, til here as well. Time to rewrite parts of my scripts and to hit the reference & docs.
Nekomata: Well message must be either "!on" or "!off" because of message == "!off" or message == "!on" condition. boolean must be the value of message == "!on" comparison. boolean must be either true or false based on the comparison. Dousea: that's a damn smartass if-condition 
But ya all forgot string.lower
VADemon: Are you praising or insulting ? About the string.lower, put it under line 3.1
message = message:lower()

LUA - Precedence
I would use parenthesis just to make it clearer tho.
(message == "!on") as a condition, returns true or false, which is a boolean value. Then the condition's result is assigned to a variable. In this case the variable's name is "boolean".
Dousea: Oh, wow that's something new for me. Though I haven't learn many things in Lua, this trick actually intrigued me. Maybe shouldn't you post in
Tricks in CS2D Scripting that you might not know.? Just asking. GeoB99: I thought everyone knows it. It just uses logic. 1

print((type({1,2,3}) == "string") and "this is a string") or "this is not a string" ) -- Prints "this is not a string"
print((type("Hello") == "string") and "this is a string") or "this is not a string" ) -- Prints "this is a string"

_Yank: You have a typo in that example. You're opening 3 brackets and closing 4 brackets. Fixed version:

print(type({1, 2, 3}) == "string" and "this is a string" or "this is not a string")
print(type("string") == "string" and "this is a string" or "this is not a string")

print("This is " .. type("") == "string" and "" or "not" .. " a string!") -- Wrong!
print("This is " .. (type("") == "string" and "" or "not") .. " a string!") -- Right!
