Difference between remote functions and remote events and difference between client and servers?

You can learn more about this by watching this quick video covering a bit of FE, and some reading. It’s mandatory you gather a collective knowledge on this as it is an imposed requirement as of ROBLOX’s Experimental Mode update of early September 2017. It’s also quite interesting and can increase performance between both the Client and the Server.

FilteringEnabled (FE) prevents automatic communication of LocalScripts to ServerScripts, primarily to reduce the probability of exploitation. Though because of this, these Scripts have been ultimately divided into their proper relationships.

####LocalScripts - Client, ServerScripts - Server

Meaning that any work related or directed towards these categories can only be achievable accordingly. Though loopholes can achieve some amount of work in its opposite.

FilteringEnabled doesn’t fully cut off communication though, it only prevents automatic communication. You can learn how to gain manual connection between these Scripts with RemoteEvents and RemoteFunctions
