From Multi Theft Auto: Wiki
This event is triggered before a resource is loaded.
Important: If you attach this event to the root element it will called when any resource starts, not just the resource your script is running inside. As such, most of the time you will want to check that the resource passed to this event matches your resource (compare with the value returned by getThisResource) before doing anything. Alternatively you can attach the event to getResourceRootElement(getThisResource()).
- startingResource: The resource that is starting
This code will output the name of any resource that is starting.
