Possible to save Instances in DataStore?

You can't directly save instances in a data store. However, you could store a literal interpretation of the instance. The two easiest ways to do this is to store an integer or a string.

###Integer Method ####Example:

local objects = {part, sword, tool, block} -- assuming those are defined

for index, object in next, objects do
	print(index, " = ", object)
end

--[[
Output:
	1 = part
	2 = sword
	3 = tool
	4 = block
]]

Thus you could save the index, and then later retrieve the index and thus the object by objects[index].

###String Method This method requires you to have a folder or model of all the objects you want to save. All you do is simply save the name of the object and then you can later retrieve the object with a simple FindFirstChild call. However, each object will need to have a unique name unlike the integer method.
