Having trouble making commands.

[Dodobee]

So I am attempting to make a mod where you can kind of create small lua scripts in game using console commands (i don't know why i'm doing this but now i'm not satisfied until i finish this complicated mod) and i literally have no idea how to do it. Here is what I have so far. Would appreciate if somebody explained how to make commands. (i am planning to make a command for every character too so that its not only sonic that you can add a script to in game)

if player.luasonic ==nil then
    player.luasonic = 0
end
   
local function playerissonic()
        if player.mo.skin ~= "sonic" then
        return
    end
   
        player.luasonic = 1
    end
   
        if player.luasonic = 1 then
        print("true")
    end

COM_AddCommand("playerissonic", playerissonic)
