Command parsing with arguments in Particubes

commands_in_particubes.lua

-- define your commands here
commands = {
	help = {
		description = "List all commands, or see one's description",
		exec = function(cmd)
			if cmd[2] ~= nil then -- if user supplied a command name
				if commands[cmd[2]] ~= nil then -- and if that command exists
					print(cmd[2] .. ": " .. commands[cmd[2]].description) -- print the command's description
				else -- if it does not exist
					print("Command not found: " .. cmd[2]) -- inform the user
				end
			else -- if the user wants to know all commands
				print("Available commands: ")
				for cmdname in pairs(commands) do -- in all commands
					print(cmdname) -- print the name
				end
			end
		end
	},
}

Client.OnChat = function(m)
	-- replace with your command prefix, can be any length
	local pfx = '%.'
	if m:find("^" .. pfx) then
		-- remove prefix
		local full = m:gsub("^" .. pfx, "")
		if (full == "") then return end -- if no command is supplied, end command parsing
		-- make a table for command and arguments
		local cmd = {}
		-- split the command by spaces and add to table
		for part in full:gmatch("([^ ]+)") do
			 table.insert(cmd, part)
		end
		if commands[cmd[1]] then -- if the command exists
			commands[cmd[1]].exec(cmd) -- run it
		else print("Command not found: " .. cmd[1]) end -- if it doesn't, inform the user
	else -- default behavior
		print(Player.Username .. " said " .. m)
		Player:TextBubble(m, 3, true)
	end
end

You can add your own commands. For example, I added a pos command that prints your position

pos = {
	description = "Print your position",
	exec = function(cmd)
		print(Player.Position)
	end
}

My first attempt at lua but thought this was neat 😄

1	fullsend = {
2		description = "Teleport to Crosshair",
3		exec = function(cmd)
4		local impact = Player:CastRay()
5			if impact.Block ~= nil then
6	    			print("RayCast:" .. " X: " .. impact.Block.Pos.X .. " Y: " .. impact.Block.Pos.Y .. " Z: " .. impact.Block.Pos.Z .. "!")
7	    			Player.Position = Number3(impact.Block.Pos.X, impact.Block.Pos.Y+15, impact.Block.Pos.Z)
8			end
9		end
10	}
