This function retrieves the resource from which the function call was made.

[[{{{image}}}|link=|]] Note: Every resource has a predefined global variable called resource that contains the resource pointer for that resource, in other words, the value that this function returns.

Syntax

resource getThisResource ( )

OOP Syntax Help! I don't understand this!

Note: This function is a static function underneath the Resource class.
Method: Resource.getThis(...)


Returns

Returns the resource in which the current script is.

Example

This example retrieves the current resource's root element and attaches it to an onResourceStart event handler. This causes the event handler to get called only when the current resource is started rather than when any resource is started, thereby reducing unnecessary overhead. 

local thisResource = getThisResource()
local resRoot = getResourceRootElement(thisResource)

addEventHandler("onResourceStart", resRoot, function()
   local resourceName = getResourceName(thisResource)
   iprint("You are in the " .. resourceName .. " resource!")
   iprint(thisResource == resource) -- true
   iprint(resRoot == resourceRoot) -- true
end)
