I need help with move saver, can anyone help me?

You can find a list of all hook names in startup.lua:

local events = {
	"new_game",
	"new_mp_game", --Called when you join a new server
	"enter_frame",
	"end_game",
	"leave_game",
	"enter_freeze",
	"exit_freeze",
	"match_begin",
	"key_up",
	"key_down",
	"mouse_button_up",
	"mouse_button_down",
	"mouse_move",
	"player_select",
	"joint_select",
	"body_select",
	"draw2d",
	"draw3d",
	"play", --Part of torishop.
	"camera",
	"console",
	"bout_mouse_down",
	"bout_mouse_up",
	"bout_mouse_over",
	"bout_mouse_outside",
	"spec_mouse_down",
	"spec_mouse_up",
	"spec_mouse_over",
	"spec_mouse_outside",
	"command", --Called when an unused /command is entered.
	"unload",
}

You can look into /data/script/sdk/ for little examples of most of the functions.

You can also create a list yourself. Every global variable is stored in a table called _G that maps the variables name to its value. To generate a ordered list from that you can use this little script:

local names = {}
local types = {}

local function find(tab, val)
	for k, v in pairs(tab) do
		if v == val then
			return k
		end
	end
	
	return -1
end

for k, v in pairs(_G) do
	names[type(v)] = names[type(v)] or {}
	table.insert(names[type(v)], k)
	if(find(types, type(v)) == -1) then
		table.insert(types, type(v))
	end
end

table.sort(types)

local out = assert(io.open("_G.txt", "w"))
for _, t in pairs(types) do
	out:write(t .. "s:\n")
	table.sort(names[t])
	
	for __, n in pairs(names[t]) do
		out:write(n .. "\n")
	end
	
	out:write("\n")
end

out:close()

echo("done")

It writes the result to a file called "_G.txt".

This of course only gives you a name without any documentation but with a bit of searching in the sdk folder, a bit of googling or some experimenting you will find out what most of them do.

Also, some functions are deprecated and don't do anything.
