This function allows tracing of MTA functions and events. It should only be used when debugging scripts as it may degrade script performance.

Syntax

bool addDebugHook( string hookType, function callbackFunction )

Required Arguments

  • hookType: The type of hook to add. This can be:
    • preEvent
    • postEvent
    • preFunction
    • postFunction
  • callbackFunction : The function to call

Returns

Returns true if the hook was successfully added, or false otherwise.

Callback parameters

pre/postEvent( resource sourceResource, string eventName, element eventSource, element eventClient, string luaFilename, int luaLineNumber, eventArguments )
pre/postFunction( resource sourceResource, string functionName, bool isAllowedByACL, string luaFilename, int luaLineNumber, functionArguments )

Example

This example will dump info about all triggered events: 

function onPreEvent( sourceResource, eventName, eventSource, eventClient, luaFilename, luaLineNumber, ... )
    local args = { ... }
    local resname
    if sourceResource then
        resname = getResourceName(sourceResource)
    else
        resname = "unknown"
    end
    outputDebugString( "preEvent"
        .. " " .. tostring(resname)
        .. " " .. tostring(eventName)
        .. " source:" .. tostring(eventSource)
        .. " player:" .. tostring(eventClient)
        .. " file:" .. tostring(luaFilename)
        .. ":" .. tostring(luaLineNumber)
        .. " #args:" .. tostring(#args)
        .. " args[1]:" .. tostring(args[1])
        )
end
addDebugHook( "preEvent", onPreEvent )
