You need to add a input box. Player enter string in the input box

local _input_string = nil --- fill your element	
function game(event) 
	if _input_string == event.uielement then
      	local variable_lucky_number = math.random(0, 100)
      	if string.find(event.content, variable_lucky_number) then
          		Chat:sendSystemMsg("Congratulation! Your lucky number is: " .. variable_lucky_number)
      	else
          		Chat:sendSystemMsg("Error Code " .. variable_lucky_number)
      	end
  		end
end
ScriptSupportEvent:registerEvent('UI.LostFocus',game)

Line 1:

local _input_string = nil --- fill your element	

• Local: This keyword is used to declare a variable with local scope, which means it’s only accessible within the block of code where it’s defined.
• _input_string: This is a variable name. You can change to another name, but if your variable has 2 letters, you need to add _ to replace for space character
• nil: This is a special value, it doesn't have any specific values. You need to change it to fit your map
• - - - fill your element: This comment line will help others understand your code

Line 2 - 10:

function game(event) 
	if _input_string == event.uielement then
      	local variable_lucky_number = math.random(0, 100)
      	if string.find(event.content, variable_lucky_number) then
          		Chat:sendSystemMsg("Congratulation! Your lucky number is: " .. variable_lucky_number)
      	else
          		Chat:sendSystemMsg("Error Code " .. variable_lucky_number)
      	end
  		end
end

• function game(event) … end: for Lua script, you need to call the function. It is the same actions in trigger.
• Function must have end and a variable name, here “game” is variable name“. You need it to register the event.
• if _input_string == event.uielement then … end: This condition will compare your string with lucky number, if they're the same - the game will chat ” Congratulation! Your lucky number is: “ .. variable_lucky_number”. However, they aren't the same - the game will chat “ Error Code ” .. variable_lucky_number“.

Line 5:

      if string.find(event.content, variable_lucky_number) then
      

• if: This starts a conditional statement in Lua.
• string.find: This is a function in Lua’s string library that searches for a pattern in a given string. It returns the start and end indices of the first occurrence of the pattern if it’s found, or nil if it’s not found.
• event.content: This likely refers to a string that is part of an event object, which might contain text that you want to search through.
• variable_lucky_number: This is a variable that holds the pattern you’re searching for within event.content.
• then: This indicates the beginning of the block of code that will execute if the condition is true.

The last line:

ScriptSupportEvent:registerEvent('UI.LostFocus',game)

• ScriptSupportEvent:registerEvent(EventName, FunctionToExecute): This method is used to register an event listener.
• EventName: This is the name of the event you want to listen for.
• FunctionToExecute: This is the function that will be called when the event occurs.
