Accesing and editing a CVAR in Lua

[amperbee]

Another problem.
I'm understanding Lua so I'm having way lesser problems than I had before.

How do I make a CVAR and how do I access it?
I made a CVAR but everytime I access it to set a variable with the value of this CVAR, it says it has a problem because Lua expected a number and not userdata.
Then how do I use the CVAR I just made, making sure only the server/admin can edit it and accesible for Lua?

You make a cvar using the CV_RegisterVar function, which returns the consvar_t data for the new cvar created:
https://wiki.srb2.org/wiki/Lua/Functions#CV_RegisterVar

local mycvar = CV_RegisterVar(table of data, see wiki)

Refer to this for dealing with the variable itself (note you cannot directly modify it in this manner):
https://wiki.srb2.org/wiki/Lua/Userdata_structures#consvar_t

If you DO intend to manually edit it's value, you may be better off using CONS_BufInsertText and using "mycvarname value" to run it in the console:

Thank you Monster Iestyn, I don't know how did I miss that part.
I just needed to access the CVAR.
