I often see people use url in projects, but I have no idea what a url is and what it’s used for. In my humble opinion, it is a string that describes the address of something, but I am not sure. Is there a document that introduces url?
In a map travel in a cooked game you might see a line like this:
/Game/Maps/MyMap?listen
This is telling the game to load MyMap.umap and be a listen server. Clients would be passed the url /Game/Maps/MyMap so it simply loads them into the map. The LoadLevel method/node is simply a wrapper for this type of URL.
