Hello

i made a script using this topic [TUT] Protect Client Script at the Highest Level

and i know that loadstring() is used to read string (functions) etc

but is there any way that i can unload this function ?

without restarting the resource

i tried to create another resource (temporary)

then the script will write meta.xml and write the script file then .. rewrite the script file and meta.xml and restart resource ..

but this is a long story ..

is there any why ?

You have to code it manually [make sure event handlers are added/removed at the right times, if timers are used, kill any and all when wanting to 'unload' it]

ok ... for example i used loadstring() for a script is full of timers .. then i want to unload it .. how i can detect the timers created by the loadstring .. i hope you understand

[UAEpro]

ummm .. no one know ? !

function overriding, like i told you on skype.

function overriding, like i told you on skype.

i still didn't understood what is that ..

but as i think i need to get all handlers,commands,timers,binds and disable it after knowing the name

For example .. removeEventHanler .. removeCommandHandler etc ..

but the problem now .. how i can get (handler name) from a string

string.find 

?

or create wrappers.

i know that .. but

if it was

addEventHandler( "onPlayerSpawn", rootElement, onPlayerSpawnHandler ) 

string.find(scriptString, "addEventHandler")

then i can find the handler but how i can know the string (event) 'onPlayerSpawn'

eventName: the name of the event which triggered the handler function.

table ,, i mean in String.find ..

[Tete omar]

string.find("the string")

[TAPL]

addEventHandler("onPlayerSpawn", rootElement, onPlayerSpawnHandler) 
  
if string.find(scriptString, "addEventHandler") then 
eventString = string.sub(scriptString, 18, #scriptString) 
end 

i think this will return "onPlayerSpawn", rootElement, onPlayerSpawnHandler)"

try to fix it..

[Arisu]

addEventHandler("onPlayerSpawn", rootElement, onPlayerSpawnHandler) 
  
if string.find(scriptString, "addEventHandler") then 
eventString = string.sub(scriptString, 18, #scriptString) 
end 

You are wrong. What would you do with compiled scripts?

You could override addEventHandler with such code:

  
local __eventsList = {}  -- table to save event handlers data 
local __addEventHandler = addEventHandler  -- save original function address 
local addEventHandler = function (eventName, element, handlerFunc)  -- override with own 
    if __addEventHandler(eventName, element, handlerFunc) then 
       table.insert(__eventsList, { ["name"] = eventName, ["element"] = element, ["handler"] = handlerFunc}) 
    end 
  end 
  

Now, think of what you can do with that events table.

Same method could be applied to other functions, liek setTimer, removeEventHandler and so on.

Of course, this should be loaded before executing any loadstring.

WRAPPER.

Code extracted from NPG, please credits us where due: http://pastebin.com/BmfYYPyn

use addCommand to add it to the list.

then use installCommands() to load all commands and removeCommands() to delete all commands. doing installCommands after deleting commands will work (because its still listed)

[UAEpro]

  
local __eventsList = {}  -- table to save event handlers data 
local __addEventHandler = addEventHandler  -- save original function address 
local addEventHandler = function (eventName, element, handlerFunc)  -- override with own 
    if __addEventHandler(eventName, element, handlerFunc) then 
       table.insert(__eventsList, { ["name"] = eventName, ["element"] = element, ["handler"] = handlerFunc}) 
    end 
  end

ok i have add this table to the script string and i load it with the script string .. but it didn't work .. did i do something wrong ?

[UAEpro]

ok .. i don't need help anymore .. i found another easier way

[Tete omar]

Good luck.
