Duplicate lua network variable

Recommended Posts

Well now I've run into another fundamental issue I don't understand; replicas

I believe I've gleaned from context from other threads I've been reading trying to solve this issue that replicas are essentially the client-side component of any object that needs to be referenced by said clients, but I don't understand what drives this or even if it's 100% correct.

So recently I created a system by which Guano is renamed to a playfully ambiguous title in keeping with the game's sort of vague reference to natural bodily functions. I do this in my modmain.lua with the following code;


and everything is well and good until I try to perform this in a world with caves. I'm assuming it's because I added the named component artificially with no supporting logic of when to replicate it? (I notice there's a named_replica.lua in the components folder) but I have no idea how to go about fixing this. The specific error log being

Clients should not have components, unless it is a replica of another component. Replicas are used when the client is supposed to read/write something from/to the server. If you have no need for something like that, then you have to remember that when adding components to an instance of a prefab, you should only do it when the code is being run on the server. To do this, you enclose the code in a server check.

if GLOBAL.TheNet and GLOBAL.TheNet:GetIsServer() then
	AddPrefabPostInit("guano", function(inst)
