I am using these Lua scripts to update the motion of objects in a gl world, but I can't seem to format the output lists so that I don't need to use a zl.join when I get back to Max. Any help is appreciated!

    values[5] = Sc*values[10]*(math.sin(2*math.pi*values[9]))

    values[6] = Sc*values[11]*(math.cos(2*math.pi*values[9]))

    values[9] = values[9]+S*((values[8]-.5)/100.)

Here is the patch in which I'm using these scripts:

this.outlets=2
local S = 1.
local Sc = 1.

function list(...)
    local values = {...}
	local message={}

	values[5] = Sc*values[10]*(math.sin(2*math.pi*values[9]))
	values[6] = Sc*values[11]*(math.cos(2*math.pi*values[9]))
	values[7] = 0.
	values[9] = values[9]+S*((values[8]-.5)/100.)

	values[5] = values[5]*2.-1
	values[6] = values[6]*2.-1
	values[7] = values[7]*2.-1

Here is the patch in which I'm using these scripts:

Aha -- solved it. Here's how to join tables (lists) in Lua where RIGHT and LEFT are two tables to be joined:

    for k,v in ipairs(RIGHT) do LEFT[#LEFT+1]=v end    

for i=1, #RIGHT do
  LEFT[#LEFT+1] = RIGHT[i]
end
